What is it?
Our bodies use food as a source of energy. The main source of energy in
food is glucose, a form of sugar. As food is digested, it is broken down
into glucose molecules which enter the bloodstream and are distributed
to cells throughout the body. For glucose to enter cells, however, insulin,
a hormone produced by the pancreas, must be present.
Normally, enough insulin is produced to move glucose into cells. In people
with diabetes, however, either not enough insulin is produced or cells
do not respond properly to the insulin. As a result, glucose remains in
the blood and cells are not provided with their main energy source.
High blood sugar levels affect
many tissues in the body including the skin, heart, kidneys, nervous system,
feet, teeth, gums and eyes. Diabetic retinopathy refers to damage to the
blood vessels of the retina caused by diabetes. These blood vessels bring
oxygen and nutrients to the retina. When the blood vessels become damaged,
they weaken and sometimes break, leaking fluid into the retina and causing
the retina may to swell. As new blood vessels grow on the retina, blurred
vision or temporary blindness can result. Scare tissue can form and cause
blindness where old blood vessles were attached to the retina.
Diabetic neuropathy may cause:
Spots floating in the visual
Poor night vision
Kidney Disease: people with
kidney disease have an increased risk of diabetic retinopathy.
High Blood Pressure: people
with high blood pressure have an increased risk of diabetic retinopathy.
High Blood Fat: people with
high blood fat have an increased risk of diabetic retinopathy.
Obesity: people who are overweight
have an an increased risk of diabetic retinopathy.
Pregnancy: women who are
pregnant have an increased risk of diabetic retinopathy.
