Type 2 diabetes is a long-term metabolic disorder in which the body cannot properly use insulin or does not produce enough of it, resulting in high blood sugar levels. If it is not controlled over time, it may cause serious health problems such as heart disease, nerve damage, kidney complications, and vision difficulties. Unlike type 1 diabetes, which develops from an autoimmune reaction, type 2 diabetes is usually associated with lifestyle factors such as excess weight, limited physical activity, and unhealthy eating habits, although genetic factors can also influence its development. Proper management typically includes lifestyle modifications like a balanced diet and regular exercise, and sometimes treatment with medication or insulin when required.
