Diabetes symptoms can sometimes become more noticeable at night because changes in blood sugar levels may affect sleep, thirst, and urination. Here are 5 symptoms that may appear or worsen at night:
- Frequent nighttime urination (nocturia)
High blood sugar can cause the kidneys to remove extra glucose through urine, leading to more trips to the bathroom during the night. - Excessive thirst at night
Fluid loss from increased urination can cause strong thirst, including waking up needing water. - Night sweats or sudden sweating
Low blood sugar (hypoglycemia), especially in people taking insulin or certain diabetes medicines, can trigger sweating, shakiness, or a racing heartbeat during sleep. - Trouble sleeping or waking frequently
Blood sugar swings, thirst, urination, or discomfort from nerve symptoms can disrupt sleep. - Tingling, burning, or numbness in the feet
Diabetes-related nerve damage (diabetic neuropathy) can cause symptoms that become more noticeable at night when there are fewer distractions.
These symptoms do not always mean someone has diabetes—they can occur with other conditions too. If you notice several of these signs, especially along with increased hunger, unexplained weight loss, fatigue, or blurred vision, it is a good idea to speak with a healthcare professional and consider a blood glucose test.
