Type 2 diabetes is one of the most common metabolic diseases in the world, often starting gradually and without obvious symptoms. This disease occurs when the body becomes resistant to insulin or does not secrete enough of it. The result of this disorder is increased blood sugar and damage to vital organs such as the heart, kidneys and eyes. An unhealthy lifestyle, excessive consumption of sugar and fat, and inactivity are the main factors in the development of type 2 diabetes. The good news is that it can be prevented by changing daily habits. A balanced diet, regular physical activity and weight control play a key role in managing this disease. Affected patients should regularly check their blood sugar and use medication or insulin if necessary. Education and awareness about diabetes can help reduce its prevalence. Also, family and community support, along with medical treatment, improves the quality of life of patients. Although type 2 diabetes is a chronic disease, with proper management, it is possible to live a healthy and dynamic life.
