High blood sugar can be easy to miss during the day. You may be busy, distracted, or blaming tiredness on stress. But at night, when the body is resting, some symptoms can become more noticeable. Waking up to urinate, feeling extremely thirsty, sleeping poorly, sweating, waking with headaches, or feeling drained in the morning may all be signs that blood sugar is not well balanced.
This does not mean every nighttime symptom is diabetes or high blood sugar. Many other things can cause poor sleep, thirst, sweating, urination, and fatigue. These include caffeine, stress, dehydration, urinary tract infections, menopause, sleep apnea, certain medications, kidney problems, and other health conditions.
Still, if these symptoms happen repeatedly or appear together, it is worth speaking with a healthcare professional and asking whether blood sugar testing is needed. High blood sugar, also called hyperglycemia, may not cause symptoms until glucose levels are significantly elevated, and some people with type 2 diabetes may have few symptoms even when levels are high. Mayo Clinic explains that symptoms of hyperglycemia often develop slowly and may include increased thirst, frequent urination, blurred vision, tiredness, and headache.
