Diabetes Nighttime Symptoms and What To Do
Diabetes can cause your blood sugar to get too high or too low during the night.
If it gets too low, you might sweat, have bad dreams, or feel tired.
If it's too high, you might need to pee a lot, be really thirsty, or get headaches.
These problems can mess up your sleep.
If you notice these things, check your sugar levels, be careful about what you eat before bed, and talk to your doctor.
Taking care of your blood sugar at night helps you sleep better and stay healthy.
