Diabetes: 5 warning signs of high blood sugar that appear at night

Shweta Singh

Here are 5 signs of high blood sugar that show up at night

High blood sugar levels force the kidneys to work harder to flush out the excess glucose, leading to increased urination at night (nocturia), which may interrupt your sleep.

Frequent Urination

Waking up with a dry mouth or an unquenchable thirst is a red flag. As your body loses fluids through frequent urination, it triggers intense thirst to compensate for the loss.

Excessive Thirst

Discomfort from dehydration, frequent trips to the bathroom, or blood sugar fluctuations can make it hard to fall or stay asleep, leading to poor-quality rest.

Restless Sleep

Some people experience night sweats due to blood sugar spikes, especially when paired with insulin resistance or uncontrolled diabetes.

Night Sweats

High blood sugar overnight can leave you waking up feeling unusually tired or with a headache, caused by poor glucose control during your sleep cycle.

Headaches or Fatigue
