9 Signs of Diabetes That May Appear at Night
Diabetes can affect the body at any time of day, and some symptoms may become more noticeable overnight. These signs are not proof of diabetes on their own, but if several occur together, it may be worth getting a blood glucose check.
1. Waking up frequently to urinate
- High blood sugar can cause the kidneys to remove extra glucose through urine, increasing nighttime trips to the bathroom.
2. Excessive thirst at night
- Fluid loss from frequent urination can lead to increased thirst, including waking up needing water.
3. Night sweats
- Blood sugar fluctuations, especially low blood sugar in people taking diabetes medications or insulin, can sometimes cause sweating during sleep.
4. Restless sleep or frequent waking
- Changes in blood sugar levels may contribute to discomfort, thirst, or the need to urinate.
5. Increased hunger late at night
- When glucose is not being used effectively by the body, some people may feel unusually hungry.
6. Tingling or numbness in the feet
- Nerve damage related to long-term high blood sugar (diabetic neuropathy) can cause burning, tingling, or numb sensations that are often more noticeable at night.
7. Leg cramps or unusual discomfort
- Some people with diabetes experience muscle discomfort or nerve-related sensations in the legs.
8. Blurred vision upon waking
- Blood sugar changes can temporarily affect the eye’s lens and vision.
9. Slow healing or repeated infections
- Frequent skin infections, urinary infections, or slow-healing wounds may be associated with high blood sugar.
When to consider testing:
Talk with a healthcare professional about a blood sugar check if you have symptoms such as:
- Increased thirst and urination
- Unexplained weight loss
- Persistent fatigue
- Blurred vision
- A family history of diabetes
- High blood pressure or excess weight
A simple blood test, such as fasting blood glucose or HbA1c, can help identify whether blood sugar levels are in a healthy range.
