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.
