5 Diabetes Symptoms That May Appear at Night
Some symptoms of diabetes can become particularly noticeable during the nighttime. They can also have many other causes, so experiencing one symptom does not mean you have diabetes.
1. Waking Up Frequently to Urinate
High blood sugar can cause the kidneys to remove extra glucose through urine. This can increase urine production and lead to repeated nighttime trips to the bathroom.
2. Excessive Thirst
Frequent urination can cause fluid loss, which may leave you unusually thirsty. Some people notice that they repeatedly wake during the night needing water.
3. Night Sweating or Shakiness
People taking insulin or certain diabetes medications can sometimes experience low blood sugar during the night. Sweating, shaking, hunger, a racing heartbeat, or waking suddenly can occur.
4. Tingling or Burning Feet
Persistently high blood sugar can damage nerves over time. This may cause burning, tingling, numbness, or unusual sensations in the feet that become more noticeable when resting at night.
5. Dry Mouth and Restless Sleep
High blood sugar and dehydration can contribute to a dry mouth and disrupted sleep. However, snoring, mouth breathing, medications, dehydration, and other conditions can cause similar symptoms.
When Should You Get Checked?
If several of these symptoms are occurring repeatedly—especially increased thirst, frequent urination, unexplained weight changes, persistent fatigue, or blurred vision—talk with a healthcare professional about blood-glucose testing.
Nighttime symptoms alone cannot diagnose diabetes. A simple blood test can help determine whether blood sugar levels are in the normal, prediabetes, or diabetes range.
