Diabetes symptoms can sometimes become more noticeable at night, but having any one of these signs does not prove you have diabetes. Common nighttime symptoms that may occur with high blood sugar include:
- Frequent urination during the night (nocturia)
- Extra glucose in the blood can make the kidneys remove more water, leading to more trips to the bathroom.
- Increased thirst or dry mouth at night
- Fluid loss from frequent urination can cause dehydration and thirst.
- Night sweats
- Blood sugar that is too low (especially in people taking insulin or certain diabetes medicines) can cause sweating, shaking, or waking up feeling unwell.
- Tingling, burning, or numbness in the feet
- Nerve damage related to diabetes (diabetic neuropathy) can cause symptoms that are more noticeable when resting.
- Poor sleep or waking up tired
- Blood sugar changes, thirst, urination, or discomfort from nerve symptoms can disrupt sleep.
Other possible signs of diabetes include increased hunger, unexplained weight loss, blurry vision, slow-healing wounds, and repeated infections.
If you’re noticing several of these symptoms, a blood glucose test (such as fasting blood sugar or HbA1c) can help clarify what’s going on.
