Here are 12 foot-related signs that may indicate high blood sugar or early diabetes.
1. Tingling or “Pins and Needles”
High blood sugar can damage nerves, especially in the feet.
If you often feel tingling, buzzing, or light electrical sensations, it may be a sign of diabetic neuropathy.
2. Numbness
Losing feeling in your feet or toes is one of the most common early symptoms of nerve damage caused by elevated blood sugar.
3. Burning Sensation
A hot, burning feeling in the feet — especially at night — is a strong indicator of nerve stress related to diabetes.
4. Cold Feet
Poor circulation caused by high blood sugar can make your feet unusually cold, even if the rest of your body feels warm.
5. Sharp or Stabbing Pain
6. Slow-Healing Cuts
High blood sugar affects blood flow and slows down the healing process.
If small cuts or blisters take a long time to heal, it may be a warning sign.
7. Dry, Cracked Skin
Diabetes can affect sweat glands, causing severely dry, flaky, or cracked skin on the feet.
8. Foot Swelling
Poor circulation and fluid retention — both linked to diabetes — can cause swelling in the feet and ankles.
9. Frequent Foot Cramps
Low circulation or nerve dysfunction due to high blood sugar can trigger cramps, especially at night.
