The short explanation
Increased thirst and passing urine often, especially at night, are classic signs of high blood sugar, so it is sensible to get a sugar test soon. When sugar is high, the kidneys pass the extra sugar into the urine, drawing water with it. That makes you urinate more and feel thirsty. There are other possible reasons too, such as drinking more fluids, tea or coffee in the evening, a urine infection, certain medicines, pregnancy, or less commonly kidney or hormonal problems. A simple blood test for sugar, sometimes with HbA1c and a urine test, can quickly tell which applies.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Tiredness, blurred vision, slow-healing wounds, repeated thrush or weight loss alongside these symptoms make high sugar more likely.
- A family history of diabetes, PCOS or a past pregnancy with high sugar increases risk.
- Burning while passing urine points more towards a urine infection.
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 or another cause. A blood and urine test are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Can we check my blood sugar and HbA1c?
- Should my urine be tested for infection?
- Could any of my medicines cause this?
- What should I do if the test is high?
