Type 2 diabetes is a lifelong (chronic)
disease in which there is a high level of sugar (glucose) in the
blood. Type 2 diabetes is the most common form of diabetes.
When you have type 2 diabetes, your fat, liver, and muscle cells
do not respond correctly to insulin.
This is called insulin resistance. As a result, blood sugar does not get into
these cells to be stored for energy.
When sugar cannot enter cells, a high level of sugar builds up in
the blood. This is called hyperglycemia.
Type 2 diabetes usually occurs slowly over time. Most people with
the disease are overweight when they are diagnosed. Increased fat makes it
harder for your body to use insulin the correct way.
Type 2 diabetes can also develop in people who are thin. This is
more common in the elderly.
Family history and genes play a role in type 2 diabetes. Low activity
level, poor diet, and excess body weight around the waist increase your chance
of getting the disease.
People with type 2 diabetes often have no symptoms at first. They
may not have symptoms for many years.
Early symptoms of diabetes may include:
·
Bladder, kidney, skin, or other infections that are more frequent
or heal slowly
·
Fatigue
·
Hunger
·
Increased thirst
The first symptom may also be:
·
Blurred
vision
