Diabetes symptoms can sometimes become more noticeable at night because changes in blood sugar may affect sleep, hydration, and the body’s normal functions. These signs do not prove someone has diabetes, but they can be reasons to check blood glucose levels or speak with a healthcare professional.
9 possible nighttime signs associated with diabetes
- Waking up often to urinate
- High blood sugar can cause the kidneys to remove extra glucose through urine, increasing the need to urinate.
- Excessive thirst at night
- Frequent urination can lead to dehydration and increased thirst.
- Night sweats
- Some people experience sweating episodes, especially during episodes of low blood sugar.
- Trouble sleeping
- Blood sugar fluctuations, thirst, or frequent bathroom trips can interrupt sleep.
- Feeling unusually hungry at night
- Some people with blood sugar problems may experience increased hunger, including after meals.
- Tingling or numbness in the feet
- Nerve damage related to diabetes can cause burning, tingling, or reduced sensation, often noticed when resting at night.
- Leg cramps or discomfort
- Some people with diabetes report muscle cramps or restless sensations, though there can be many causes.
- Blurred vision
- Changes in blood sugar can temporarily affect the shape of the eye’s lens, causing vision changes.
- Slow-healing cuts or frequent infections
- High blood sugar can affect immune function and circulation, making some infections more likely.
When to get checked
Consider talking with a healthcare professional if you have several of these symptoms, especially along with risk factors such as:
- Family history of diabetes
- Overweight or obesity
- High blood pressure
- History of gestational diabetes
- Age-related risk factors
A simple blood test, such as an A1C test or fasting blood glucose test, can help determine whether diabetes or prediabetes is present.
