5 Diabetes Symptoms That Can Appear at Night
Some diabetes-related symptoms can become especially noticeable at night. They aren’t specific to diabetes, but recurring symptoms are worth discussing with a healthcare professional.
- Frequent urination — High blood glucose can cause the kidneys to remove extra glucose and water, leading to repeated nighttime trips to the bathroom.
- Excessive thirst or a dry mouth — Fluid loss from frequent urination can leave you unusually thirsty.
- Night sweats or shakiness — In people taking insulin or certain diabetes medications, blood sugar can sometimes fall too low during sleep, causing sweating, trembling, a racing heart, or nightmares.
- Tingling, burning, or pain in the feet — Diabetes-related nerve damage can cause symptoms that become more noticeable when you’re resting at night.
- Persistent tiredness or disrupted sleep — Frequent urination, thirst, nerve discomfort, or blood-glucose fluctuations can interfere with sleep and leave you exhausted the next day.
Important: These symptoms don’t prove that you have diabetes. If they’re recurring—especially excessive thirst and urination—ask about a blood-glucose test such as fasting glucose or HbA1c.
If you have diabetes and experience confusion, fainting, seizures, or severe symptoms of very low or very high blood sugar, seek urgent medical care.
