Type 1 Diabetes

Type 1 diabetes is a chronic metabolism disease caused by the failure of insulin production due to the destruction of beta cells in the pancreas damage. Although typically diagnosed during childhood or adolescence, it can occur at any age. Classified as an autoimmune disease, type 1 diabetes requires lifelong insulin supplementation, necessitating continuous health management by affected individuals life. According to data from the World Health Organization (WHO), type 1 diabetes accounts for approximately 5 to 10 percent of all diabetes cases.

Causes and Risk Factors

The exact cause of type 1 diabetes is unknown, but it is believed to be triggered by an interaction between genetic susceptibility and environmental factors such as viral infections and nutrition habits. Mutations in the HLA gene group are among the most significant genetic risk factors. Additionally, variations in prevalence across geographic regions—for example, higher rates in Finland—highlight the importance of environmental influences.

Signs and Diagnosis

The disease presents with sudden onset symptoms including excessive thirst (polydipsia), frequent urination (polyuria), unexplained weight loss, and fatigue like. Elevated blood glucose levels (hyperglycemia) and the presence of ketones in urine support the diagnosis. A definitive diagnosis is established through fasting blood glucose measurement, HbA1c testing, and autoantibody screening (anti-GAD, anti-IA2).

Treatment and Management

The primary treatment for type 1 diabetes is external replacement of the missing insulin. For this purpose, rapid-acting, intermediate-acting and long-acting insulins are used. Today, technologies such as insulin pumps and continuous glucose monitoring systems (CGM) facilitate better blood glucose control. Treatment plans are supported by dietary management, regular physical activity, and patient education.

Social and Psychological Impact

The disease affects individuals’ quality of life not only physically but also psychologically. Particularly among adolescents, difficulties adhering to treatment and diabetes-related anxiety are common. Diabetes education programs and support groups play a critical role during this process. Moreover, initiatives to increase school and awareness in schools and workplaces facilitate social integration.
