Diabetes doesn’t always show obvious symptoms during the day — sometimes, your body sends subtle warning signs while you sleep. These nighttime symptoms are often overlooked, but recognizing them early can make a huge difference in managing or even preventing diabetes complications.
Here are 9 important signs that may appear at night and what they mean for your health.
1. Frequent Nighttime Urination (Nocturia) 🚽
If you find yourself waking up multiple times to use the bathroom, it may be a sign of high blood sugar. When glucose levels are elevated, your kidneys work harder to filter and remove excess sugar through urine — making you need to go more often, even during the night.
2. Excessive Thirst While Sleeping 💧
Waking up with a dry mouth or craving water constantly at night can be another red flag. High blood sugar causes dehydration because your body is losing fluids through frequent urination.
