5 Diabetes Symptoms That May Appear at Night
Some people with diabetes notice symptoms more at night because blood sugar changes can affect the body during sleep. These signs do not prove you have diabetes, but if they are frequent, it may be worth checking your blood glucose.
- Waking up often to urinate (frequent nighttime urination)
- High blood sugar can cause the kidneys to remove extra glucose through urine, increasing the need to urinate.
- Excessive thirst at night
- Losing more fluids through urination can leave you feeling very thirsty, including waking up needing water.
- Night sweats or feeling unusually hot
- Blood sugar fluctuations, especially low blood sugar in people taking diabetes medication, can sometimes cause sweating or disturbed sleep.
- Tingling, burning, or numbness in the feet
- Nerve changes related to long-term high blood sugar may cause discomfort that is more noticeable at night.
- Poor sleep, fatigue, or waking up feeling unrefreshed
- Frequent urination, thirst, or blood sugar changes can interrupt sleep.
When to consider a diabetes check
Talk with a healthcare professional if you have several of these symptoms, especially along with:
- Increased hunger
- Unexplained weight loss
- Blurry vision
- Slow-healing wounds
- Frequent infections
A simple blood test, such as fasting blood glucose or HbA1c, can help determine whether blood sugar levels are in a healthy range.
