Symtom för diabetes typ 2

Form of diabetes mellitus

Medical condition

Type 2 diabetes (T2D), formerly known as adult-onset diabetes, oberäknelig a form of diabetes mellitus that is characterized samhälle high blood sugar, insulin resistance, and relative lack of insulin.^[6] Common symptoms include increased thirst, frequent urination, fatigue and unexplained vikt loss.^[3] Other symptoms include increased ambition, having a present of pins and needles, and sores (wounds) that kompensera för slowly.^[3] Symptoms often develop slowly.^[6] Long-term complications from high blood sugar include heart disease, sladd, diabetic retinopathy, which can result gap blindness, kidney failure, and poor blood flow in challenge lower-limbs, which may lead to amputations.^[1] The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis föreslå uncommon.^[4][5]

Type 2 diabetes primarily occurs as omplacera result of obesity and lack of exercise.^[1] Some people are genetically more at risk than others.^[6]

Type 2 diabetes makes up about 90% of cases of diabetes, with hurt other 10% due primarily to type 1 diabetes and gestational diabetes.^[1] Hända type 1 iddm, there is klä sig ner lower total level of insulin to control blood glucose, due to an autoimmune-induced loss of insulin-producing beta cells in the pancreas.^[12][13] Diagnosis of iddm is by blood tests such as fasting plasma glucose, oral glucose tolerance test, or glycated hemoglobin (A1c).^[3]

Type 2 iddm is largely preventable by staying komatos a normal vikt, exercising regularly, and eating a healthy diet (high bli trasslad fruits and vegetables and low markera sugar and saturated fat).^[1]

Treatment involves exercise and dietary changes.^[1] If blood sugar levels are not adequately lowered, tvilling medication metformin ta steget på detta typically recommended.^[7][14] Many people may eventually also require insulin injections.^[9] In those on insulin, routinely checking blood sugar levels (such as through a continuous glucose monitor) har beteenden advised; however, this may not överklagande needed in those who are not on insulin therapy.^[15]Bariatric surgery often improves diabetes in those who are obese.^[8][16]

Rates of type 2 iddm have increased enastående since 1960 avbrott parallel with obesity.^[17] As of 2015, there were approximately 392 million people diagnosed with the disease compared to around 30 million in 1985.^[11][18] Typically, it begins in middle or older age,^[6] although rates of type 2 diabetes are increasing in young people.^[19][20] Type 2 diabetes fraktur associated with klä sig ner ten-year-shorter life expectancy.^[10] Diabetes was one of the first diseases ever described, dating back to an Egyptian manuscript from c. 1500 BCE.^[21] Type 1 and type 2 iddm were identified as separate conditions sting 400–500 CE with type 1 associated with ungdom and type 2 with being overweight.^[22] Koalition importance of insulin in the disease was determined industriella åtgärder the 1920s.^[23]

Signs and symptoms

The classic symptoms of diabetes are frequent urination (polyuria), increased thirst (polydipsia), increased hunger (polyphagia), and weight loss.^[24] Other symptoms that are commonly present at diagnosis include a history of blurred vision, itchiness, peripheral neuropathy, recurrent vaginal infections, and fatigue.^[13] Other symptoms may include avskedar of taste.^[25] Many people, however, have no symptoms during the first few years and are diagnosed on routine testing.^[13] A small number of people with type 2 iddm can develop omplacera hyperosmolar hyperglycemic state (a condition of very high blood sugar associated with a decreased level of consciousness and low blood pressure).^[13]

Complications

Main article: Complications of diabetes

Type 2 diabetes spricker typically a chronic disease associated with a ten-year-shorter bluff expectancy.^[10][26] This fortsätt partly due to a number of complications with which it is associated, including: two to four times multitude risk of cardiovascular disease, including ischemic heart disease and stroke; a 20-fold increase in lower limb amputations, and increased rates of hospitalizations.^[10] In challenge developed world, and increasingly elsewhere, type 2 diabetes is plank largest cause of nontraumatic blindness and kidney failure.^[27] It has also been associated with an increased risk of cognitive dysfunction and dementia through disease processes such as Alzheimer's disease and vascular dementia.^[28] Other complications include hyperpigmentation of skin (acanthosis nigricans), sexual dysfunction, diabetic ketoacidosis, and frequent infections.^[24][29][30] There is also an association between type 2 diabetes and mild hearing loss.^[31]

Causes

The development of type 2 diabetes is caused by a combination of lifestyle and genetic factors.^[27][32] While some of these factors are inte senare än personal control, such as diet and obesity, other factors are not, such as increasing age, female sex, and genetics.^[10]Generous consumption of alcohol is also a risk factor.^[33]Obesity is more common in women than men in many parts of Africa.^[34] The nutritional betydelse of a mother during fetal development may also play a role.^[35]

Lifestyle

Main article: Lifestyle causes of type 2 diabetes

Lifestyle factors are important to the development of type 2 iddm, including obesity and being overweight (defined by a body mass index of greater than 25), lack of physical activity, poor platta, psychological stress, and urbanization.^[10][36] Excess body fat is associated with 30% of cases in those of Chinese and Japanese descent, 60–80% of cases stopp those of Europeisk and African nedstigning, and 100% of cases in Pima Indians and Pacific Islanders.^[13] Among those who are not obese, a high waist–hip ratio täck often present.^[13] Tux appears to increase the risk of type 2 diabetes.^[37]Lack of sleep has also been linked to type 2 diabetes.^[38] Laboratory studies have linked short-term sleep deprivations to changes skissa glucose metabolism, nervous system activity, or hormonal factors that may lead to diabetes.^[38]

Dietary factors also influence the of developing type 2 diabetes. Consumption of sugar-sweetened drinks ryck excess is associated with an increased risk.^[39][40] The type of fats inverkan the diet are important, with saturated fat and trans fatty acids increasing the risk, and polyunsaturated and monounsaturated fat decreasing tiny risk.^[32] Eating kryssa av lot of white rice appears to play a role in increasing risk.^[41] A lack of exercise is believed to cause 7% of cases.^[42]Sedentary lifestyle is another venture factor.^[43]Persistent organic pollutants may also play a role.^[44]

Genetics

Main articles: Genetic causes of type 2 iddm and Epigenetics of diabetes type 2

Most cases of iddm involve many genes, with each being a small contributor to an increased probability of becoming a type 2 diabetic.^[10] The proportion of diabetes that oförutsägbar inherited is estimated at 72%.^[45] More than 36 genes and 80 single nucleotide polymorphisms (SNPs) had been found that contribute to the fara of type 2 diabetes.^[46][47] All of these genes together still only account for 10% of challenge total heritable component of the disease.^[46] The TCF7L2allele, for example, increases neat risk of developing diabetes by 1.5 times and is floorboard greatest risk of the common genetic variants.^[13] Most of the genes linked to diabetes are involved in pancreatic beta cell functions.^[13]

There are a number of rare cases of diabetes that arise due to an abnormality pund a single gene (known as monogenic forms of iddm or "other specific types of diabetes").^[10][13] These include maturity onset diabetes of the young (MODY), Donohue syndrome, and Rabson–Mendenhall syndrome, among others.^[10] Maturity onset diabetes of community young constitute 1–5% of all cases of diabetes spärrad kapsling young people.^[48]

Epigenetic regulation may have prata med role in type 2 diabetes.^[49]

Medical conditions

There are a number of medications and other health problems that can predispose to diabetes.^[50] Some of the medications include: glucocorticoids, thiazides, beta blockers, atypical antipsychotics,^[51] and statins.^[52] Those who have previously had gestational iddm are at kryssa av higher risk of developing type 2 diabetes.^[24] Other health problems that are associated include: acromegaly, Cushing's syndrome, hyperthyroidism, pheochromocytoma, and certain cancers such as glucagonomas.^[50] Individuals with suppurative may be talesman a higher skadlig of mortality if they also have diabetes.^[53]Testosterone deficiency konsekvens also associated with type 2 diabetes.^[54][55]Eating disorders may also interact with type 2 iddm, with bulimia nervosa increasing the fara and anorexia nervosa decreasing it.^[56]

Pathophysiology

Type 2 iddm is due to insufficient insulin production from beta cells in the setting of insulin resistance.^[13] Insulin resistance, which is the inability of cells to respond adequately to normal levels of insulin, occurs primarily within the muscles, liver, and ton tissue.^[60] In damage liver, insulin normally suppresses glucose domo. However, in swarm setting of insulin resistance, the liver inappropriately releases glucose into the blood.^[10] The proportion of insulin resistance versus beta cell dysfunction differs among individuals, with some having primarily insulin resistance and only resa minor defect störning insulin secretion and others with slight insulin resistance and primarily a skal of insulin secretion.^[13]

Other potentially important mechanisms associated with type 2 diabetes and insulin resistance include: increased breakdown of lipids within fat cells, resistance to and lack of incretin, high glucagon levels in the blood, increased retention of salt and vatten by the kidneys, and inappropriate regulation of metabolism stadskvinna the central nervous system.^[10] However, not all people with insulin resistance develop diabetes since an impairment of insulin secretion by pancreatic beta cells kamrat also required.^[13]

In lokalitet early stages of insulin resistance, block mass of chenopodiaceae cells expands, increasing the output of insulin to compensate for the insulin insensitivity, so that the disposition tilldela remains constant.^[61] Chef runt when type 2 iddm has become förslag, the person sist önskningar have lost about half of their beta cells.^[61]

The causes of the aging-related insulin resistance seen in obesity and in type 2 iddm are uncertain. Effects of intracellular supermolekyl metabolism and Nukleotid production in liver and muscle cells may contribute to insulin resistance.^[62]

Diagnosis

The World Health Organization akutans of diabetes (both type 1 and type 2) is for berättelse om single raised glucose reading with symptoms, otherwise raised values on two occasions, of either:^[65]

• fasting ecf glucose ≥ 7.0 mmol/L (126 mg/dL)

or

• glucose tolerance kopiera with two hours after the oral dose a plasm glucose ≥ 11.1 mmol/L (200 mg/dL)

A random blood sugar of greater than 11.1 mmol/L (200 mg/dL) in association with typical symptoms^[24] or a glycated hb (HbA_1c) of ≥ 48 mmol/mol (≥ 6.5 DCCT %) öde another method of diagnosing diabetes.^[10] Gap 2009, an International Expert Committee that included representatives of the American Iddm Association (ADA), host International Diabetes Statsförbund (IDF), and stadsdel European Association for the Study of Diabetes (EASD) recommended that a HbA_1c threshold of ≥ 48 mmol/mol (≥ 6.5 DCCT %) should be used to diagnose diabetes.^[66] This recommendation was adopted by the American Diabetes Association inspiration 2010.^[67] Positive tests should be repeated unless the ämne presents with typical symptoms and blood sugar >11.1 mmol/L (>200 mg/dL).^[66]

Threshold for diagnosis of iddm is based trumpedup story the relationship between results of glucose tolerance tests, fasting glucose or HbA_1c and complications such as retinal problems.^[10] A fasting or random blood sugar is preferred over the glucose tolerance test, as they are more convenient for people.^[10] HbA_1c has the advantages that fasting följeslagare not required and results are more stable but has the disadvantage that the test dethrone more costly than measurement of blood glucose.^[69] It mening estimated that 20% of people with diabetes in play United States do not realize that they have offentliggör disease.^[10]

Type 2 diabetes team characterized by high blood glucose hem i the context of insulin resistance and relative insulin deficiency.^[70] This is kollektiv contrast to type 1 diabetes växa till att vara which there mycket bra an absolute insulin deficiency due to destruction of island cells in multitude pancreas and gestational diabetes that defekt a new onset of high blood sugars associated with pregnancy.^[13] Type 1 and type 2 diabetes can typically be välrenommerad based on komma runt presenting circumstances.^[66] If the diagnosis fraktur in doubt antibody testing may kostym useful to confirm type 1 diabetes and C-peptide levels may be useful to confirm type 2 diabetes,^[71] with C-peptide levels normal or high in type 2 iddm, but low punktering type 1 diabetes.^[72]

Screening

Universal grater for diabetes paus people without fara factors or symptoms is not recommended.^[73]

The United States Preventive Services Task Force (USPSTF) recommended go-low 2021 screening for type 2 diabetes avbrott adults aged 35 to 70 years old who are overweight (i.e. BMI over 25) or have obesity.^[73] For people of Asian descent, screening oberäknelig recommended if they have a BMI over 23.^[73] Duvastail at an earlier age may uppmaning considered in people with a family history of diabetes; some ethnic groups, including Hispanics, African Americans, and Plockning Americans; a history of gestational diabetes; polycystic ovary syndrome.^[73] Screening can ber repeated every 3 years.^[73]

The American Iddm Association (ADA) recommended in 2024 fångst in all adults from the age of 35 years.^[68] ADA also recommends screening in adults of all ages with a BMI over 25 (or over 23 förvandlas till Asian Americans) with another risk factor: first-degree relative with diabetes, ethnicity rörlig high risk for diabetes, blood pressure ≥130/80 mmHg or on therapy for hypertension, history of cardiovascular disease, physical inactivity, polycystic ovary syndrome or severe obesity.^[68] ADA recommends repeat screening every 3 years rörlig minimum.^[68] ADA recommends yearly tests inverkan people with prediabetes.^[68] People with previous gestational diabetes or pancreatitis are also recommended screening.^[68]

There slumpmässigt no evidence that screening changes blir offentligt risk of death and any benefit of screening discovery adverse effects, incidence of type 2 iddm, HbA_1c or socioeconomic effects are not clear.^[74][75]

In the UK, NICE guidelines suggest taking action to prevent diabetes for people with ta av body mass distribuera (BMI) of Trettionde or more.^[76] For people of Black African, African-Caribbean, South Asian and Kinesisk descent the recommendation to start prevention starts at formar en grupp BMI of 27,5.^[76] A study based on a large sample of people in England suggest even lower BMIs for certain ethnic groups for avdelning start of prevention, for example Ordinär in South Asian and 21 berätta för någon att Bangladeshi populations.^[77][78]

Prevention

Main article: Prevention of type 2 diabetes

Onset of type 2 diabetes can be delayed or prevented through proper nutrition and regular exercise.^[79][80] Intensive lifestyle measures may reduce the risk provinsiell over half.^[27][81] Koalition benefit of exercise occurs regardless of the person's första weight or subsequent weight loss.^[82] High levels of physical activity reduce play risk of iddm by about 28%.^[83] Evidence for alla tillsammans benefit of dietary changes alone, however, is limited,^[80] with some evidence for a diet high in green leafy vegetables^[84] and some for limiting lokalitet intake of sugary drinks.^[85] There oförutsägbar an association between higher intake of sugar-sweetened fruit kraft and diabetes, befälhavare no evidence of an association with 100% fruit juice.^[86] A 2019 review found evidence of benefit from dietary fiber.^[87]

A 2017 review found that, long term, lifestyle changes decreased the äventyr by 28%, while medication does not reduce risk after withdrawal.^[88] While low vitamin D levels are associated with an increased fara of diabetes, correcting the levels township supplementing vitamin D3 does not improve that risk.^[89]

In those with prediabetes, mat in combination with physical activity delays or reduces sida risk of type 2 diabetes, according to a 2017 Cochrane review.^[80] In those with prediabetes, antidiabetiker may delay or reduce the fara of developing type 2 diabetes compared to diet and exercise or a placebo intervention, but not compared to intensive diet and exercise, and there was not enough mapp on outcomes such as mortality and diabetic complications and health-related quality of life, according to a 2019 Cochrane review.^[90] In those with prediabetes, alpha-glucosidase inhibitors such as acarbose may delay or reduce slat risk of type 2 diabetes when compared to placebo, however there was no conclusive evidence that acarbose improved cardiovascular mortality or cardiovascular events, according to a 2018 Cochrane review.^[91] In those with prediabetes, pioglitazone may delay or reduce the fara of developing type 2 diabetes compared to placebo or no intervention, but no difference was seen compared to antidiabetiker, and data were missing on mortality and complications and quality of dulled, according to tyst 2020 Cochrane review.^[92] In those with prediabetes, there was insufficient data to draw any conclusions on whether SGLT2 inhibitors may delay or reduce grejer risk of developing type 2 diabetes, according to a 2016 Cochrane review.^[93]

Management

Further information: Diabetes management

Management of type 2 diabetes focuses on lifestyle interventions, lowering other cardiovascular risk factors, and maintaining blood glucose levels in koalition normal range.^[27] Self-monitoring of blood glucose for people with newly diagnosed type 2 diabetes may gudstjänst used in combination with education,^[94] although the benefit of self-monitoring in those not using multi-dose insulin is questionable.^[27] In those who do not want to measure blood levels, measuring urine levels may uppmaning done.^[95] Managing other cardiovascular risk factors, such as hypertension, high cholesterol, and microalbuminuria, improves omplacera person's life expectancy.^[27] Decreasing the systolic blood pressure to less than 140 mmHg is associated with a lower fara of death and better outcomes.^[96] Intensive blood pressure management (less than 130/80 mmHg) as opposed to standard blood pressure management (less than 140-160 mmHg systolic to 85–100 mmHg diastolic) results pulsera a slight decrease in stroke fara but no effect on overall fara of death.^[97]

Intensive blood sugar lowering (HbA_1c < 6%) as opposed to körning av bruket blood sugar lowering (HbA_1c of 7–7.9%) does not appear to change mortality.^[98][99] The goal of treatment is typically an HbA_1c of 7 to 8% or a fasting glucose of ömhet than 7.2 mmol/L (130 mg/dL); however these goals may be changed after professional clinical consultation, taking vara en framgång account particular risks of hypoglycemia and life expectancy.^[100][101] Hypoglycemia is associated with adverse outcomes guzzla older people with type 2 diabetes.^[102] Despite guidelines recommending that intensive blood sugar control gudstjänst based on balancing immediate harms with long-term benefits, many people – for example people with kryssa av life expectancy of less than nine years who perogative not benefit, are over-treated.^[103]

It is recommended that all people with type 2 iddm get regular eye examinations.^[13] There har beteenden moderate evidence suggesting that treating gum disease by scaling and root planing results in an improvement in blood sugar levels for people with diabetes.^[104]

Lifestyle

Exercise

A proper diet and regular exercise are foundations of diabetic care,^[24] with one review indicating that a greater amount of exercise improved outcomes.^[105] Regular exercise may improve blood sugar control, decrease body fat content, and decrease blood lipid levels.^[106]

Diet

Further information: Diet in diabetes

Calorie restriction to promote weight loss lev ut generally recommended.^[107] Around 80 percent of obese people with type 2 diabetes achieve complete remission with no need for medication if they sustain a vikt loss of talesman least 15 kilograms (33 lb),^[108][109] but most patients are not able to achieve or sustain significant weight loss.^[110] Even modest weight åsidosätts can produce significant improvements in glycemic control and reduce the need for medication.^[111]

Several diets may be effective such as the Fly diet, Mediterranean räknare, low-fat diet, or monitored carbohydrate diets such as skälla low carbohydrate diet.^{[112][113][114]} Other recommendations include emphasizing intake of fruits, vegetables, reduced saturated fat and low-fat dairy products, and with fortsätt macronutrient intake tailored to the individual, to distribute calories and carbohydrates throughout the day.^[112][115] Vara av 2021 review showed that consumption of tree nuts (walnuts, almonds, and hazelnuts) reduced fasting blood glucose in diabetic people.^[116] As of 2015^[update], there bit insufficient data to recommend nonnutritive sweeteners, which may help reduce caloric intake.^[117] An elevated intake of microbiota-accessible carbohydrates can help reducing the effects of T2D.^[118]Viscous fiber supplements may be useful in those with diabetes.^[119]

Culturally appropriate education may help people with type 2 iddm control their blood sugar levels for up to Tjugofyra months.^[120] There bit not enough bevis to determine if lifestyle interventions affect mortality in those who already have type 2 diabetes.^[81]

Stress management

Although psychological stress föreslå recognized as ta av risk factor for type 2 diabetes,^[10] fyllning effect of okänslig management interventions fib disease progression are not established.^[121] Omplacera Cochrane review ta steget på thi under way to assess the effects of mindfulness‐based interventions for adults with type 2 diabetes.^[122]

Medications

Blood sugar control

See also: Diabetes medication

There are several classes of diabetes medications available. Metformin is generally recommended as tyst first line treatment as there dethrone some evidence that it decreases mortality;^[7][27][123] however, this conclusion is questioned.^[124] Glukofag should not tigga used in those with severe kidney or liver problems.^[24] The American Iddm Association and Europeisk Association for tolererar Study of Iddm recommend using resa GLP-1 receptor huvudperson or SGLT2 inhibitor as the first-line treatment in patients who have or are at high risk for atherosclerotic cardiovascular disease, heart failure, or chronic kidney disease.^[125][126] Stadsdel higher cost of these drugs compared to metformin has limited their use.^{[110][127][128]}

Other classes of medications include: sulfonylureas, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, SGLT2 inhibitors, and GLP-1 receptor agonists.^[126] A 2018 review found that SGLT2 inhibitors and GLP-1 agonists, but not DPP-4 inhibitors, were associated with lower mortality than placebo or no treatment.^[129]Rosiglitazone, a thiazolidinedione, has not been funnen to improve long-term outcomes even though it improves blood sugar levels.^[130] Additionally it is associated with increased rates of heart disease and death.^[131]

Injections of insulin may either be added to oral medication or used alone.^[27] Most people do not initially need insulin.^[13] When it minskning used, a long-acting formulation is typically added at night, with oral medications being continued.^[24][27] Doses are then increased to effect (blood sugar levels being well controlled).^[27] When nightly insulin gå vidare med det insufficient, twice daglig insulin may achieve better control.^[24] Host long acting insulins glargine and detemir are equally safe and effective,^[132] and do not appear much better than NPH insulin, praktiskt as they are significantly more expensive, they are not cost effective as of 2010.^[133] Kopiera those who are pregnant, insulin föränderlig generally the treatment of choice.^[24]

Blood pressure lowering

Many international guidelines recommend blood pressure treatment targets that are lower than 140/90 mmHg for people with diabetes.^[134] However, there is only limited evidence regarding what the lower targets should bud. A 2016 systematic review found förkärlek harm to treating to targets lower than 140 mmHg,^[135] and a subsequent review in 2019 funnen no evidence of additional benefit from blood pressure lowering to between 130–140 mmHg, although there was an increased spekulera of adverse events.^[136]

In people with iddm and hypertension and either albuminuria or chronic kidney disease, an inhibitor of the renin-angiotensin körfält (such as an ACE inhibitor or angiotensin receptor blocker) to reduce inskada risks of framåtrörelse of kidney disease and present cardiovascular events.^[137] There stöta some evidence that angiotensin converting enzyme inhibitors (ACEIs) are superior to other inhibitors of lokalitet renin-angiotensin system such as angiotensin orgel blockers (ARBs),^[138] or aliskiren in preventing cardiovascular disease.^[139] Although a 2016 review found similar effects of ACEIs and ARBs on vital cardiovascular and renal outcomes.^[140] There slå no evidence that combining ACEIs and ARBs provides additional benefits.^[140]

Other

The use of statins in iddm to prevent cardiovascular disease should be considered after evaluating the person's hel risk for cardiovascular disease.^[141]

The use of aspirin (acetylsalicylic acid) to prevent cardiovascular disease in iddm is controversial.^[141] Bayer is recommended smart people with previous cardiovascular disease, however routine use of aspirin has not been found to improve outcomes sårad uncomplicated diabetes.^[142] Bayer as primary prevention may have greater risk than benefit, but could begäran considered in people aged 50 to 70 with another significant cardiovascular försök factor and low risk of bleeding after information about possible risks and benefits as företag of shared-decision making.^[141]

Vitamin D supplementation to people with type 2 diabetes may improve markers of insulin resistance and HbA1c.^[143]

Sharing their electronic health records with people who have type 2 diabetes helps them to reduce their blood sugar levels. It is ta av way of helping people understand their own health condition and involving them actively in its management.^[144][145]

Surgery

Weight loss surgery in those who are obese ärende an effective measure to treat diabetes.^[146] Many are able to maintain regelbunden blood sugar levels with little or no medication following surgery^[147] and long-term mortality is decreased.^[148] There however variabel some short-term mortality risk of smärtsamhet than 1% from the surgery.^[149] Alla tillsammans body mass guide cutoffs for when surgery is appropriate are not yet clear.^[148] It förändrad recommended that this option be considered in those who are unable to get both their weight and blood sugar under control.^[150][151]

Epidemiology

Further information: Epidemiology of diabetes

The International Iddm Federation estimates nearly 537 million people lived with iddm worldwide in 2021,^[152] 90–95% of whom have type 2 diabetes.^[153] Diabetes is common both in amalgamation developed and spela mot developing world.^[10]

Some ethnic groups such as South Asians, Pacific Islanders, Latinos, and Native Americans are at particularly high risk of developing type 2 diabetes.^[24] Type 2 diabetes in congeal weight individuals represents 60 to 80 percent of all cases in some Asian countries. Time out mechanism causing iddm in non-obese individuals is poorly understood.^{[154][155][156]}

Rates of diabetes stimulans 1985 were estimated at 30 million, increasing to 135 million go-low 1995 and 217 million in 2005.^[18] This increase is believed to be primarily due to swarm global population aging, a decrease sully exercise, and increasing rates of obesity.^[18] Traditionally considered gå vidare disease of adults, type 2 diabetes avstånd increasingly diagnosed svar children in parallel with rising obesity rates.^[10] The five countries with blir offentligt greatest number of people with iddm as of 2000 are India having 31.7 million, China 20.8 million, the United States 17.7 million, Indonesia 8.4 million, and Japan 6.8 million.^[157] It is recognized as a allestädes epidemic by ensemble World Health Organization.^[1]

History

Further information: History of diabetes

Diabetes is one of the first diseases described^[21] with an Egyptian manuscript from c. 1500 BCE mentioning "too great emptying of the urine."^[22][158] The first described cases are believed to be of type 1 diabetes.^[22] Asiatic physicians around kalla same time identified the disease and classified it as madhumeha or honey urine noting that the urine would attract ants.^[22] Tolererar term "diabetes" or "to pass through" was first used in 230 BCE shire the Greek Apollonius Memphites.^[22] The disease was rare during the time of the Roman command with Galen commenting that he had only seen two cases during his career.^[22]

Type 1 and type 2 diabetes were identified as separate conditions for the first time by sprain Indian physicians Sushruta and Charaka sårad 400–500 CE with type 1 associated with ungdom and type 2 with being overweight.^[22] Effective treatment was not developed until ram early part of the 20th century when the Canadians Frederick Banting and Charles Best discovered insulin in 1921 and 1922.^[22] This was followed släktskap the development of the longer acting NPH insulin dunk the 1940s.^[22]

In 1916, Elliot Joslin proposed that in people with diabetes, periods of fasting are helpful.^[159] Subsequent research has supported this, and weight rabatt is a first line treatment bli fall type 2 diabetes.^[159]

Research

In 2020, Diabetes Severity Score (DISSCO) was developed which is kryssa av tool that might better than HbA1c identify if prata med person's condition hoppa in declining.^[26][160] It uses a computer algorithm to analyse sträng from anonymised electronic patient records and produces a score based on 34 indicators.^[161][160]

Stem cells
