Understanding Diabetes

Diabetes is a chronic condition affecting how the body processes glucose. It impacts millions of people worldwide and requires careful management of blood sugar levels through diet, exercise, and sometimes medication.

Types of Diabetes

Type 1 diabetes is an autoimmune disorder where the body doesn’t produce insulin. It typically develops in childhood or adolescence. Type 2 diabetes is more common, accounting for about 90% of cases. In this type, the body becomes resistant to insulin or doesn’t produce enough.

Gestational diabetes occurs during pregnancy and usually resolves after childbirth. However, it increases the risk of developing type 2 diabetes later in life.

Blood Sugar Management

Blood sugar control is crucial for diabetics. Regular monitoring helps track glucose levels and guide treatment decisions. Diet plays a key role, with emphasis on balanced meals and portion control.

Exercise improves insulin sensitivity and helps lower blood sugar. Many diabetics benefit from 150 minutes of moderate activity per week. Medications like metformin or insulin may be necessary to maintain target glucose levels.

Stress management and adequate sleep also contribute to better blood sugar control. Regular check-ups with healthcare providers ensure proper management and early detection of complications.
