The idea that there are “9 signs of diabetes that appear at night” is a common health headline, but nighttime symptoms alone cannot diagnose diabetes. Some people with high blood sugar may notice symptoms that are more noticeable during the night or that disturb sleep.
Possible nighttime signs associated with diabetes or high blood sugar include:
- Frequent urination at night (nocturia)
- Excess glucose in the blood can cause the kidneys to remove more water, leading to more trips to the bathroom.
- Excessive thirst at night
- Fluid loss from frequent urination can leave you unusually thirsty.
- Night sweats
- Can occur in some people, especially if blood sugar drops too low (hypoglycemia), though many other conditions can also cause sweating.
- Trouble sleeping
- Blood sugar fluctuations, thirst, or frequent urination may interrupt sleep.
- Tingling, burning, or numbness in the feet
- Nerve damage related to diabetes (diabetic neuropathy) can cause symptoms that are often more noticeable at night.
- Leg cramps or restless legs sensations
- Nerve or circulation issues may contribute in some people.
- Increased hunger or waking up hungry
- Blood sugar problems can affect how the body uses energy.
- Dry mouth
- Dehydration from high blood sugar can contribute to a dry mouth.
- Slow-healing cuts or recurring infections
