The short explanation
It could be. When blood sugar is high, sugar spills into the urine, which can give it a sweet or fruity smell. Feeling very thirsty, passing urine often, tiredness and weight loss are common signs of high blood sugar, including undiagnosed diabetes. These symptoms deserve a blood sugar test soon. Other things can change the smell of urine, such as some foods, vitamins and dehydration, but the combination with constant thirst makes checking your sugar the priority.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A fasting blood sugar, a random sugar or an HbA1c test is usually enough to start. Many PHCs and government hospitals offer these tests at low or no cost. A family history of diabetes, being overweight, a past diagnosis of diabetes in pregnancy, or PCOS increase the chance.
- High sugar also makes urine infections and genital thrush more likely, so mention any itching or burning.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether you have diabetes. That needs blood tests and a clinician's assessment.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Could my symptoms be due to high blood sugar?
- Which blood tests should I do?
- Should my urine be tested for sugar, ketones or infection?
- What should I do while I wait for the results?
