What are the early signs of diabetes?
Last updated September 3, 2026.
The classic early signs: constant thirst, peeing more than usual (especially at night), unusual tiredness, and weight loss without trying. Supporting signs: blurred vision, slow-healing cuts, frequent thrush or UTIs, genital itching, and tingling feet. The nuance that matters: type 2 often has NO symptoms for years, so risk factors justify asking for a blood test (HbA1c) even when you feel fine - over 40, overweight, family history, or past gestational diabetes. Type 1 comes on fast over days to weeks; the same symptoms plus vomiting and stomach pain are urgent. Pymander is a free AI doctor, 24/7 by text, and can help you weigh symptoms and risk.
What to do
- Know the four classics: thirst, frequent urination, tiredness, unexplained weight loss.
- Test on risk, not just symptoms: type 2 hides for years; HbA1c is a simple blood test.
- Treat fast-onset with vomiting as urgent: that pattern can be diabetic ketoacidosis.
- Do not panic, do not shelve: early type 2 is highly manageable - the miss is the risk.
