Understanding Diabetes

Types of Diabetes (Type 1, Type 2, Gestational)

Diabetes is a persistent condition that impairs the body's ability to manage blood sugar (glucose) levels. It primarily comes in three forms: Type 1, Type 2, and gestational diabetes. Type 1 diabetes occurs when the immune system attacks and destroys the insulin-producing beta cells in the pancreas, leading to little or no insulin production. Type 2 diabetes is characterized by insulin resistance, where the body’s cells do not respond effectively to insulin, often combined with a gradual decline in insulin production. Gestational diabetes develops during pregnancy when the body cannot produce enough insulin to meet the increased demands, often resolving after childbirth but increasing the risk of developing Type 2 diabetes later in life.
