9 Signs of Diabetes That May Appear at Night
Some symptoms of diabetes can become more noticeable at night, although they are not always caused by diabetes. If these signs are frequent or persistent, it is worth discussing them with a healthcare professional and considering a blood sugar check.
1. Waking up often to urinate
High blood sugar can cause the kidneys to remove extra glucose through urine, which may increase nighttime urination.
2. Excessive thirst at night
Frequent urination can lead to fluid loss, causing increased thirst, including waking up thirsty.
3. Night sweats
Episodes of sweating at night can occur for several reasons, including blood sugar fluctuations, especially in people taking diabetes medications that can cause low blood sugar.
4. Feeling unusually hungry at night
Changes in how the body uses glucose may contribute to increased hunger.
5. Trouble sleeping
Blood sugar changes, frequent bathroom trips, thirst, or discomfort can interfere with sleep.
6. Tingling, burning, or numbness in the feet
Nerve damage related to diabetes (diabetic neuropathy) can cause uncomfortable sensations that are often more noticeable at rest or at night.
7. Slow-healing cuts or skin problems
Diabetes can affect circulation and immune function, which may make wounds heal more slowly.
8. Blurry vision
Changes in blood sugar levels can temporarily affect the eye’s lens and cause fluctuating vision.
9. Unexplained fatigue
Poor sleep, blood sugar changes, or difficulty using glucose for energy can contribute to tiredness.
When to consider getting checked
Talk with a healthcare professional if you have several of these symptoms, especially along with risk factors such as:
- Being overweight
- A family history of diabetes
- High blood pressure
- High cholesterol
- A history of gestational diabetes
A simple blood test, such as a fasting glucose test or HbA1c test, can help determine blood sugar status.
Important: These symptoms are not proof of diabetes on their own. Many other conditions can cause similar signs, so proper evaluation is the best way to know the cause.
