The idea that there are “9 signs of diabetes that appear at night” is a popular health headline, but nighttime symptoms are not unique to diabetes and can have many other causes. However, some people with diabetes may notice certain symptoms more at night because of changes in blood sugar during sleep.
9 Possible Nighttime Signs Linked With Diabetes
- Waking up often to urinate
- High blood sugar can cause the kidneys to remove extra glucose through urine, increasing urination.
- Excessive thirst at night
- Frequent urination can lead to dehydration and increased thirst.
- Night sweats
- Sweating during sleep may occur during episodes of low blood sugar (hypoglycemia).
- Feeling hungry soon after dinner or during the night
- Blood sugar fluctuations can sometimes trigger hunger.
- Tingling, burning, or numb feet
- Nerve changes related to diabetes may cause discomfort that becomes more noticeable at rest.
- Poor sleep or frequent waking
- Blood sugar changes, thirst, or the need to urinate may disrupt sleep.
- Dry mouth
- Dehydration from elevated blood glucose may contribute to a dry mouth sensation.
- Morning fatigue despite enough sleep
- Interrupted sleep or overnight blood sugar changes can leave some people feeling tired.
- Slow healing or frequent infections
- These are not only nighttime symptoms, but they can be warning signs associated with diabetes.
When to Consider Getting Checked
Talk with a healthcare professional about diabetes testing if you have symptoms such as:
- Increased thirst and urination
- Unexplained weight loss
- Persistent fatigue
- Blurred vision
- A family history of diabetes
- Risk factors such as high blood pressure or excess body weight
A simple blood test, such as fasting blood glucose or HbA1c, can help determine whether blood sugar levels are in a healthy range.
