Diabetes can affect nerves over time, especially when blood sugar remains high. This may cause tingling, numbness, burning, or discomfort in the feet or legs. At night, these sensations may feel more noticeable because there are fewer distractions.
Some people describe it as pins and needles, heat, crawling sensations, or mild burning in the toes or soles of the feet.
Mayo Clinic notes that tingling and numbness in the hands and feet can happen in people with diabetes because too much blood sugar can affect nerve function.
7. Leg Cramps or Foot Discomfort
Nighttime leg cramps can have many causes, including dehydration, muscle fatigue, circulation issues, low minerals, medications, or long sitting. But diabetes can also contribute to leg and foot discomfort through nerve and circulation changes.
If cramps or foot pain happen together with numbness, tingling, slow-healing sores, or changes in skin temperature or color, it is important to seek medical advice.
People with diabetes need to take foot symptoms seriously because nerve changes can make injuries harder to notice.
8. Feeling Very Hungry at Night
Unusual hunger can happen when the body is not using glucose properly. Even if there is sugar in the blood, the cells may not receive enough energy, especially when insulin is not working normally.
Some people wake up hungry or feel the need to snack during the night. Others may feel shaky, weak, or anxious if blood sugar drops too low.
The CDC lists increased hunger among common diabetes symptoms, along with frequent urination, increased thirst, fatigue, mood changes, blurry vision, and frequent infections.
9. Feeling Exhausted in the Morning
