1. Frequent Urination at Night (Nocturia)
High blood sugar causes the kidneys to remove excess glucose through urine, which can lead to waking up multiple times to urinate.
2. Excessive Thirst
Losing more fluid through urination can make you feel unusually thirsty, including during the night or upon waking.
3. Night Sweats
People taking insulin or certain diabetes medications may experience low blood sugar during sleep, which can cause sweating, nightmares, or restless sleep.
4. Restless or Poor-Quality Sleep
Blood sugar fluctuations, discomfort, or frequent bathroom trips can interfere with sleep.
5. Dry Mouth During the Night
Dehydration related to high blood sugar can contribute to waking up with a dry mouth.
6. Leg Cramps or Tingling
Over time, diabetes can damage nerves, a condition called Diabetic Neuropathy. Symptoms may be more noticeable at night.
7. Burning or Painful Feet
Some people with nerve damage experience burning, stabbing, or aching sensations in their feet that worsen in the evening.
8. Blurred Vision
High blood sugar can affect the lenses of the eyes, sometimes causing vision changes that may be noticed during the day or night.
9. Unexplained Fatigue
Poor sleep, blood sugar fluctuations, and the body’s difficulty using glucose effectively can contribute to persistent tiredness.
Other Common Diabetes Symptoms
In addition to nighttime symptoms, watch for:
- Increased hunger
- Unexplained weight loss
- Slow-healing cuts or wounds
- Frequent infections
- Blurred vision
- Increased thirst and urination
These symptoms are often associated with Type 2 Diabetes and can also occur with Type 1 Diabetes.
When to Get Checked
Consider speaking with a healthcare professional if you have:
- Frequent nighttime urination
- Excessive thirst
- Unexplained weight changes
- Persistent fatigue
- A family history of diabetes
A simple blood glucose test or HbA1c test can help determine whether diabetes is present.
Important Note
Many people with early Type 2 Diabetes have no symptoms at all, which is why regular screening is important if you have risk factors such as obesity, a family history of diabetes, high blood pressure, or a history of gestational diabetes.
