Five diabetes-related symptoms that may become noticeable at night include:
- Frequent urination during the night (nocturia)
High blood sugar can cause the kidneys to remove extra glucose through urine, leading to more trips to the bathroom while sleeping. - Excessive thirst at night
Fluid loss from frequent urination can cause strong thirst, including waking up needing water. - Night sweats
Some people with diabetes experience sweating at night, particularly during episodes of low blood sugar (hypoglycemia). - Sleep disturbances and fatigue
Blood sugar fluctuations may cause difficulty staying asleep, frequent waking, or feeling unusually tired despite getting enough rest. - Tingling, burning, or numbness in the feet
Diabetic nerve damage (neuropathy) can cause uncomfortable sensations that may feel worse at night when there are fewer distractions.
These symptoms can have many causes besides diabetes. If they are persistent—especially increased urination, unusual thirst, unexplained weight changes, blurred vision, or ongoing fatigue—a healthcare professional can check blood glucose levels and evaluate the cause.
