Is type 2 diabetes only caused by being overweight?

No. Extra weight raises risk, but genetics, inactivity, ectopic fat, age, and other factors can lead to type 2 diabetes even at a normal weight.

What is LADA (type 1.5 diabetes)?

LADA is a slow-onset autoimmune diabetes in adults. It's often mistaken for type 2, but treatment needs can differ and insulin may be needed sooner.

What tests diagnose diabetes?

Common tests include A1C, fasting plasma glucose, and sometimes an oral glucose tolerance test (OGTT).

What are the most common symptoms of diabetes?

Frequent urination, increased thirst and hunger, fatigue, blurry vision, and sometimes unintended weight loss.

If I'm thin, should I still change my diet and exercise habits?

Often yes—focusing on muscle-building, daily movement, and balanced meals can improve insulin sensitivity. Work with a clinician for a personalized plan.
