6. Tingling or numbness in fingers and toes
This is another one of the prediabetes signs and it might surprise many people. The high levels of blood sugar can affect the nerves, which can lead to this sensation of tingling or numbness.
This phenomenon is called diabetic neuropathy, and it is recommended that you go to your doctor immediately if you notice any unexplained numbness in your fingers and toes.
Nerve damage is a serious condition, and the main problem with it is that it is irreversible. Once the nerves suffer damage, it is already done, and you can’t do anything about it. So, the best choice is to visit your doctor, and if that is the case, start treatment as soon as possible.
