9 Signs of Diabetes That Appear at Night

Frequent nighttime urination (nocturia)
Waking up several times to pee can happen when excess sugar pulls fluid into the urine.

Excessive thirst at night
Feeling very thirsty—especially after waking up—can be your body trying to replace lost fluids.

Night sweats
Low blood sugar (hypoglycemia), particularly in people already on diabetes meds, can cause heavy sweating during sleep.

Restless or poor sleep
Blood sugar swings can interfere with deep, restful sleep, leading to tossing and turning.

Leg cramps or tingling
Nerve issues (diabetic neuropathy) may cause burning, tingling, or cramps that feel worse at night.

Itchy skin
High blood sugar can lead to dry, itchy skin, which is often more noticeable when you’re lying in bed.

Headaches upon waking
