Diabetes Symptoms at Night: 7 Signs of High Blood Sugar
High blood sugar can cause symptoms at any time of day. Some may become more noticeable at night, especially when they interrupt sleep.
1. Frequent Nighttime Urination
High blood sugar can cause increased urination, which may mean waking up several times during the night.
2. Excessive Thirst
You may wake up feeling unusually thirsty or have a dry mouth.
3. Blurred Vision
High blood sugar can temporarily affect vision, causing blurriness.
4. Unusual Tiredness
Persistent high blood sugar can leave you feeling weak or unusually tired.
5. Headaches
Headaches can occur when blood sugar is high, although they have many other possible causes.
6. Tingling or Burning Feet
Diabetes-related nerve damage can cause burning, tingling, numbness, or pain in the feet. These symptoms can be worse at night.
7. Increased Hunger
Some people with diabetes experience increased hunger even after eating.
Important: These symptoms do not prove that your blood sugar is high. Many can have other causes. If you regularly experience several of them, ask a healthcare professional about checking your blood glucose or A1C.
If you have diabetes and develop very high blood sugar with vomiting, trouble breathing, fruity-smelling breath, severe weakness, confusion, or fainting, seek urgent medical care.
Bottom line: Don’t wait for symptoms to appear after 10 p.m. Regular blood sugar testing is a much more reliable way to know your glucose level.
