Type 2 diabetes: symptoms, causes & treatment
Type 2 diabetes means blood sugar stays too high — often linked to weight, diet and inactivity. Many people are diagnosed after routine blood tests; early management prevents complications.
Editorial information by Kaiser Khan. Not clinically reviewed.
Why it happens
Insulin resistance and reduced insulin production — strongly associated with obesity, family history, ethnicity and age. Not caused by eating sugar alone.
Treatment
NHS care is first-line for diagnosis and ongoing diabetes management. Private online clinics may support weight management where appropriate — diabetes medicines require GP or specialist oversight.
Self-care that helps
Weight loss where indicated, balanced diet, regular activity, and attend NHS diabetic screening if diagnosed.
When to get help
Suspected diabetes needs blood tests — do not self-diagnose. Chest pain, confusion or very high blood sugar are emergencies.
