Diabetes symptoms can sometimes become more noticeable at night, but there is no single set of “night-only” warning signs that proves someone has diabetes. These symptoms can also have other causes. If several occur together—especially with risk factors for diabetes—it may be worth getting a blood glucose test.
9 possible nighttime signs linked with diabetes
- 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 fluid through urination can lead to increased thirst.
- Waking up hungry
- Some people experience increased hunger due to the body’s difficulty using glucose effectively.
- Night sweats
- Low blood sugar episodes (especially in people taking insulin or certain diabetes medications) can cause sweating, shakiness, or waking suddenly.
- Poor sleep or frequent waking
- Blood sugar fluctuations, thirst, or urination can disrupt sleep.
- Tingling or numbness in the feet
- Nerve damage related to diabetes (diabetic neuropathy) can cause burning, tingling, or discomfort that may be more noticeable at night.
- Leg cramps or unusual sensations
- Nerve or circulation issues can contribute to nighttime discomfort.
- Slow-healing cuts or skin problems
- Diabetes can affect the body’s ability to heal and fight infections.
- Unexplained fatigue
- Poor sleep and difficulty using glucose for energy can contribute to tiredness.
When to get checked
Consider speaking with a healthcare professional about diabetes testing if you have symptoms such as increased thirst, frequent urination, unexplained weight changes, fatigue, or vision changes—especially if you have risk factors like family history, high blood pressure, being overweight, or a history of gestational diabetes.
