Have you ever woken up in the middle of the night feeling unusually thirsty, needing to urinate, or experiencing unexplained sweating? Although these symptoms can have many causes, they may sometimes be associated with changes in blood sugar levels.
Diabetes is a chronic condition that affects how the body regulates glucose, commonly known as blood sugar. When glucose levels remain too high, the condition can affect various parts of the body, including the kidneys, nerves, eyes, and cardiovascular system.
Some people notice diabetes-related symptoms more clearly at night because these symptoms interrupt their sleep. Others may experience few or no noticeable symptoms, particularly during the early stages of type 2 diabetes.
Recognizing possible warning signs is important, but symptoms alone cannot confirm a diagnosis. A blood test is needed to determine whether someone has diabetes.
Here are five symptoms worth understanding and knowing when to seek medical advice.
1. Frequent Urination During the Night
One possible symptom of diabetes is needing to urinate more frequently than usual, including during the night.
When blood glucose becomes excessively high, the kidneys work to remove some of the excess glucose through urine. This process can increase urine production and cause more frequent bathroom visits.
You might notice that you wake up several times during the night to urinate, even when you have not intentionally increased your fluid intake.
However, nighttime urination does not automatically indicate diabetes. Other possible causes include drinking fluids shortly before bed, urinary tract problems, certain medications, sleep disorders, and prostate enlargement.
What should you do?
If you regularly wake up to urinate more often than usual, especially if you also experience excessive thirst or unexplained weight loss, arrange a medical assessment.
2. Unusual Thirst and a Dry Mouth
Persistent thirst is another common symptom of elevated blood sugar.
When the body loses additional fluid through increased urination, dehydration can develop. This may cause a dry mouth and a strong desire to drink water.
You might wake up feeling thirsty even after drinking water before going to sleep.
Some people also notice that they need to keep water beside their bed because their mouth feels unusually dry during the night.
Nevertheless, dry mouth can also result from sleeping with the mouth open, nasal congestion, certain medications, or inadequate fluid intake.
What should you do?
Pay attention to thirst that is persistent, unexplained, or accompanied by frequent urination. A healthcare professional can determine whether blood glucose testing is appropriate.
Severe thirst accompanied by vomiting, abdominal pain, confusion, or rapid, deep breathing requires urgent medical attention because these can be warning signs of a serious diabetes complication.
