Overview

Type 2 diabetes is a long-term condition in which the body becomes resistant to insulin or doesn't produce enough, causing blood sugar to rise. It's strongly linked with lifestyle and genetic factors.

Symptoms

Early symptoms can be subtle and include increased thirst, frequent urination, fatigue, and blurred vision. Many people have no symptoms for years.

Causes and risk factors

Risk factors include excess weight, physical inactivity, family history, and age. Insulin resistance develops gradually over time.

Treatment

Management combines lifestyle changes — diet, exercise, weight management — with medication when needed. Regular blood-sugar monitoring is key.
