15 Sneaky Symptoms That May Indicate High Blood Sugar

2. Tingling or Numbness in Your Hands and Feet

That strange “pins and needles” sensation in your fingers or toes might seem harmless at first—perhaps you’ve been sitting in an awkward position or your circulation is slightly off. But if you find yourself frequently experiencing tingling, numbness, or even burning sensations in your hands and feet, it could be a warning sign of diabetic neuropathy. High blood sugar damages the tiny blood vessels that supply oxygen and nutrients to your nerves. Over time, this can lead to nerve dysfunction, making it harder for them to send proper signals to your brain. This often starts in the extremities—feet, toes, hands, and fingers—where circulation is naturally weaker. Many people brush off these sensations as temporary discomfort, but persistent tingling or numbness could indicate the early stages of nerve damage. If left untreated, diabetic neuropathy can lead to more severe nerve issues, including chronic pain, weakness, or even loss of sensation. This can increase the risk of unnoticed injuries, infections, or foot ulcers, which are particularly dangerous for those with diabetes. If you frequently experience these sensations with no clear cause, a blood sugar check could provide important insight into what’s going on beneath the surface.
