Maturity-onset diabetes, or type 2 diabetes, is a metabolic disease characterized by elevated blood glucose levels due to insulin resistance and/or insufficient insulin secretion. The condition often develops in older people, but in recent years it has also been detected in younger patients, causing concern among health care professionals. The causes and mechanisms of this disease are multifactorial, including both genetic predispositions and external factors such as lifestyle and environment. The constant increase in the incidence of type 2 diabetes among young people highlights the need for early diagnosis and effective preventive measures.
History of the disease and interesting historical facts
Diabetes has been known to mankind for thousands of years, and its description can be found in ancient texts. The first mentions of the disease date back to ancient Egyptian papyri, which recorded symptoms consistent with diabetes. The term “diabetes” itself comes from the Greek word “siphon,” which refers to excessive urination, one of the characteristic symptoms of the disease. In the 20th century, with the discovery of insulin in 1921, there was a significant change in approaches to the treatment of diabetes, which significantly improved the quality of life of patients. The increase in the incidence of type 2 diabetes among young people is a relatively new phenomenon, which has become noticeable due to global changes in lifestyle, such as urbanization and the spread of fast food.
Epidemiology
According to the World Health Organization, the incidence of type 2 diabetes is growing steadily and is becoming one of the most serious public health problems. In 2021, more than 537 million cases were registered worldwide, and this figure is expected to increase to 783 million by 2045. There has been a significant increase in cases of this disease among young people, especially in the 18-30 age group. In particular, in recent decades, there has been a noticeable increase in the incidence of this disease among adolescents and young adults, which is associated with an increase in the number of overweight people and a sedentary lifestyle.
Genetic predisposition to this disease
Maturity-onset diabetes has a significant genetic component. Research shows that having a family history of diabetes more than doubles an individual’s risk of developing the disease. Many genes associated with type 2 diabetes have now been identified. These include genes involved in glucose metabolism, insulin resistance, and inflammatory modulation. Mutations in genes such as TCF7L2, FTO, and PPARG have been associated with increased risk of developing diabetes in a number of large epidemiological studies. Genetic predisposition combined with environmental factors creates a dangerous tandem that contributes to the development of the disease.
Risk factors for the development of this disease
The risks associated with developing adult-onset diabetes can be divided into several categories:
- Physical factors: sedentary lifestyle, overweight and obesity, poor diet high in sugar and fat.
- Chemical factors: Exposure to toxic substances such as some pesticides and chemicals that can negatively affect carbohydrate metabolism.
- Social factors: insufficient level of education, access to health services, unstable social environment.
- Other possible factors: stress, high cholesterol, hypertension.
Diagnosis of this disease
Diagnosis of type 2 diabetes involves several stages. The main symptoms of the disease may include:
- Frequent urination
- Increased thirst
- Fatigue and weakness
- Unexplained weight loss
- Blurred vision
Laboratory tests are key to diagnosis. Basic tests include fasting blood glucose levels and blood glucose levels two hours after a meal. In addition, a glycated hemoglobin (HbA1c) test is used, which provides an idea of the average blood sugar concentration over the past three months. Radiological examinations, such as an abdominal ultrasound, may be needed to rule out other metabolic diseases. The differential diagnosis includes type 1 diabetes and other endocrine disorders.
Treatment
Treatment of type 2 diabetes requires a comprehensive approach. Primary measures include lifestyle modifications, such as dietary changes, increased physical activity, and weight loss. Pharmacological treatment begins with metformin, which helps lower blood sugar levels. If metformin is ineffective, other groups of drugs such as sulfonylurea, GLP-1 agonists, or incretins may be added. Surgical treatment in the form of bariatric surgery may also be recommended for obesity leading to diabetes. Current research shows that such surgeries can significantly improve metabolic parameters in patients with type 2 diabetes. Other treatments may include the use of traditional medicine and nutritional counseling.
List of medications used to treat this disease
The main classes of drugs used to treat type 2 diabetes include:
- Metformin
- Sulfonylureas (glimepiride, glibenclamide)
- DPP-4 inhibitors (sacogliptin, sidogliptin)
- GLP-1 agonists (liraglutide, semaglutide)
- SGLT2 inhibitors (dapagliflozin, canagliflozin)
Disease monitoring
Monitoring the condition of a patient with type 2 diabetes is a key element in disease management. Glucose levels should be monitored regularly, with HbA1c determined at least twice a year. The prognosis with timely and adequate therapy is quite favorable, but there are risks of complications associated with cardiovascular diseases, nephropathy, retinopathy, and neuropathy. Educational programs on diabetes management play an important role in reducing the risk of complications and improving the quality of life of patients.
Age-related features of the disease
Type 2 diabetes may present differently in younger people than in older adults. Younger patients often have a more aggressive course of the disease and more pronounced metabolic disturbances. They are also more likely to have associated pathologies, such as polycystic ovary syndrome or hypertension. Importantly, obesity in childhood and adolescence increases the likelihood of early onset of type 2 diabetes, which requires increased monitoring and intervention by health care professionals.
