Diabetic peripheral neuropathy is an irreversible condition causing tingling and even numbness or pain in your arms and legs. This is caused by not controlling your blood sugar which leads to damage to the nerves in your limbs. If you get your Diabetes in check you can sometimes lessen the symptoms and stop it from progressing further.
If you have diabetes or are at risk for developing it, it is important that you lose weight. Being overweight or obese can cause blood glucose levels to be dangerously high, which can cause severe complications, including coma or death. Try to eat healthier and stick to a moderate exercise plan. It's never to late to change, and you can be successful no matter how many previous failed attempts you've had.
