The short explanation
Slim people can and do get type 2 diabetes, and this is especially common in South Asians. Many Indians carry more fat inside the belly and around the liver even when they look thin, and have less muscle, which makes the body less sensitive to insulin. Genes and family history also play a big role, as does how much insulin the pancreas can make. In a young, slim woman with high sugar, doctors may also consider other types of diabetes, such as type 1 or forms that come on slowly in adults, because treatment can differ. Tests such as antibodies or other blood tests may help. It is worth discussing this with your doctor rather than assuming it is the usual type.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Family history, PCOS, a past pregnancy with high sugar, low physical activity and poor sleep all raise risk regardless of weight.
- Losing weight without trying, excessive thirst and tiredness at a young age may point towards other types and should be mentioned.
- Building muscle with strength exercises can help the body handle sugar better even if you do not need to lose weight.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you which type of diabetes you have or why. Your doctor may need further tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Which type of diabetes do you think this is?
- Do I need antibody or other tests?
- Will my treatment differ because I am slim?
- What exercise would help me?
When to seek help
