9 Signs of Diabetes That May Appear at Night
Diabetes can sometimes cause symptoms that are more noticeable during the night. These signs do not always mean someone has diabetes, but they may be reasons to get blood sugar checked.
- Frequent nighttime urination (nocturia)
High blood sugar can cause the kidneys to remove extra glucose through urine, leading to more trips to the bathroom. - Excessive thirst at night
Losing more fluid through urination can cause increased thirst, including waking up needing water. - Night sweats
Sweating during sleep may occur with blood sugar fluctuations, especially episodes of low blood sugar in people taking diabetes medications. - Trouble sleeping
Frequent urination, thirst, discomfort, or blood sugar changes may disrupt sleep. - Tingling or numbness in hands and feet
Nerve damage related to diabetes (diabetic neuropathy) can cause burning, tingling, or pain that may feel worse at night. - Increased hunger after dinner or overnight
Blood sugar problems can affect how the body uses energy, sometimes causing unusual hunger. - Dry mouth or dry skin
Dehydration from high blood sugar can contribute to dryness. - Blurred vision that comes and goes
Changes in blood sugar levels can temporarily affect the eye’s lens and cause fluctuating vision. - Slow-healing cuts, itching, or recurring infections
High blood sugar can affect the immune system and circulation, increasing the risk of certain infections.
Important: Many people with type 2 diabetes have few or no symptoms for years. The most reliable way to know is through testing, such as fasting blood glucose, HbA1c, or other tests recommended by a healthcare professional.
Seek urgent medical help if symptoms include severe weakness, confusion, vomiting, difficulty breathing, or very high blood sugar readings.
