Nerve damage (also
called diabetic neuropathy) makes it hard for your nervesto send
messages to the brain and other parts of the body. If you have
nerve damage, you may lose feeling in parts of your body or have a painful tingling feeling.
Neuropathy
most often affects the feetand legs. If you have neuropathy,you may not
be able to feel a sore on your foot. The sore can become infected and,
in serious cases, the footmay have to be amputated (removed). People
who have neuropathy may
continue walking on a foot that has damaged joints or bones. This can
lead
to a condition called Charcot foot that causes the injured foot
tobecome deformed. However, this problem can often be avoided.
If you have diabetes, check your feet every day. If you see swelling and
redness and feel warmth in your foot, see your doctor immediately.
These can be signs of Charcot foot. Your doctor should also check your
feet at least once a year.
Eye problems
The retina is the part of the eye that is sensitive to light and helps you
see. Diabetes can damage and weaken the small blood vessels in the
retina. This damage is called diabetic retinopathy.
When
theblood vessels are weak, they can leak fluid. This causes swelling in
the eye that blurs your vision. If retinopathy gets worse, it may lead
to blindness by causing your retina to break away from the back of the
eye.
Laser surgery can often be used to treat or slow down
retinopathy, especially if the problem is found early. People who have
diabetes should have an eye exam once a year.
