If you’re wondering about diabetes symptoms that may become noticeable at night, some common ones are:
Frequent urination (especially waking several times to urinate): High blood glucose causes the kidneys to remove more glucose and water.
Excessive thirst or a dry mouth: Losing more fluid through urination can make you thirsty.
Night sweats or shakiness: In someone taking insulin or certain diabetes medicines, these can sometimes indicate low blood sugar (hypoglycemia).
Hunger or waking up feeling unusually hungry: Can occur when glucose isn’t being used effectively.
Restless sleep or fatigue: Blood-glucose fluctuations can interfere with sleep.
Tingling, burning, or numbness in the feet: Long-term high glucose can damage nerves (diabetic neuropathy).
Itching or recurrent infections: High glucose can increase the risk of some fungal or urinary infections.
An important distinction
Waking once at night to urinate doesn’t mean you have diabetes. It can happen because of evening fluids, caffeine, prostate problems, certain medications, sleep apnea, or other conditions.
If you repeatedly experience several of these symptoms, the useful next step is a blood-glucose test and/or HbA1c test, rather than trying to diagnose diabetes from symptoms alone.
If you have very high thirst and urination together with vomiting, abdominal pain, deep/rapid breathing, confusion, or extreme weakness, seek urgent medical care because these can be signs of a dangerous metabolic emergency.
