The short explanation
Many people with raised blood sugar feel nothing at all for years, which is why a test tells you more than waiting for symptoms. When symptoms do come, the common ones are feeling very thirsty, passing urine often (including at night), tiredness, blurred vision, cuts that are slow to heal, repeated thrush or urine infections, and weight loss without trying. The usual tests are an HbA1c, which reflects your average sugar over the last two to three months, and a fasting blood sugar. A single random reading from a camp or a glucometer is a prompt to get proper testing, not a diagnosis either way.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Type 2 diabetes tends to arrive earlier in South Asian people, and at a lower body weight, than the Western figures suggest. A parent or sibling with diabetes, a past gestational diabetes, PCOS, high blood pressure, or carrying weight around the waist all make testing worth doing sooner and more regularly.
- Diagnosis usually rests on two abnormal results, or one clearly abnormal result with symptoms, so a borderline number is normally repeated rather than acted on alone.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether you have diabetes, what your own results mean, or how often you should be tested. Those depend on your numbers, your history and an examination.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Which test do you recommend for me — HbA1c, fasting sugar, or both?
- Does anything in my family or pregnancy history mean I should be tested more often?
- If the result is borderline, when would we repeat it?
- Should my blood pressure and cholesterol be checked at the same time?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- Get emergency care now (call 112 or 108, or go to the nearest emergency department) for extreme thirst with vomiting, stomach pain, fast or deep breathing, a fruity smell on the breath, confusion or unusual drowsiness. In someone with known diabetes, that can mean dangerously high sugar.
- See a clinician within days for a lot of thirst, passing urine far more often than usual, blurred vision, or losing weight without trying.
- Book a routine appointment for a first check if you have a family history, had gestational diabetes or have PCOS and have never been tested.
