Nerve damage caused by fluctuating blood sugar can be dangerous, particularly for people with diabetes.

The condition can affect most any tissues of the body, but notably the heart and circulatory system.

The American Diabetes Association says potential warning signs of neuropathy include:

• Feeling dizzy or fainting after standing up.
• Fainting for no apparent reason.
• Rapid heartbeat when you are at rest.
• Having a heart attack without chest pain or other common warning signs.
