Restless Sleep
Diabetes doesn’t only lead to dangerous spikes in blood sugar, but can cause dips — known as hypoglycemia — as well. Nighttime hypoglycemia may cause nighttime sweats, as well as vivid dreams. “I’ve heard these described as horrible nightmares,” says Paul. If hypoglycemia is suspected, it’s important to test blood-sugar levels and follow the 15/15 rule if numbers are low: Experts recommend having a 15-gram serving of carbohydrates, such as 4 ounces of fruit juice or 2 tablespoons of raisins, then waiting 15 minutes before retesting numbers.
