Although
there is no cure for diabetes yet, daily treatment helps control blood sugar,
and may reduce the risk of complications. Under a doctor's supervision,
treatment usually involves a combination of weight loss, exercise, and medication.
What Is Diabetes?
The two
types of diabetes, insulin-dependent (type 1) and noninsulin-dependent
(type 2), are different disorders. While the causes, short-term effects, and
treatments for the two
types differ, both can cause the same long-term health
problems. Both types also affect the body's ability to use digested food for
energy. Diabetes doesn't interfere with digestion, but it does prevent the body
from using an important product of digestion, glucose (commonly known as
sugar), for energy.
After a
meal the digestive system breaks some food down into sugar. The blood carries
the sugar throughout the body, causing blood sugar levels to rise. In response
to this rise the hormone insulin is released into the bloodstream to signal the
body tissues to metabolize or burn the sugar for fuel, causing blood sugar
levels to return to normal. A gland called the pancreas, found just behind the
stomach, makes insulin. Sugar the body doesn't use right away goes to the
liver, muscle, or fat for storage.
In
someone with diabetes, this process doesn't work correctly. In people with type
1 diabetes, the pancreas doesn't produce insulin. This condition usually
begins in childhood. People with this kind of diabetes must have daily insulin
injections to survive.
In people
with type 2 diabetes the pancreas usually produces some insulin, but the
body doesn't respond very well to the insulin signal and, therefore, doesn't
metabolize the sugar properly, a condition called insulin resistance.
Insulin resistance is an important factor in type 2 diabetes.

Remember
- Only a doctor can treat diabetes.
- Treatment usually involves weight loss, exercise, and medication.
- Daily treatment helps control diabetes and may reduce the risk of complications.
- Diabetes interferes with the body's use of food for energy.
- While type 1 and type 2 diabetes are different disorders, they can cause the same complications.
What Are the Symptoms of Diabetes?
The symptoms of
diabetes may begin gradually and can be hard to identify at first. They may
include fatigue, a sick feeling, frequent urination, especially at night, and
excessive thirst. When there is extra sugar in blood, one way the body gets rid
of it is through frequent urination. This loss of fluids causes extreme thirst.
Other symptoms may include sudden weight loss, blurred vision, and slow healing
of skin, gum, and urinary tract infections. Women may notice genital itchingA
doctor also may suspect a patient has diabetes if the person has health
problems related to diabetes. For instance, heart disease, changes in vision,
numbness in the feet and legs, or sores that are slow to heal, may prompt a
doctor to check for diabetes. These symptoms do not mean a person has diabetes,
but anyone who has these problems should see a doctor.

What Causes Type 2 Diabetes?
There is
no simple answer to what causes type 2 diabetes. While eating sugar, for
example, doesn't cause diabetes, eating large amounts of sugar and other rich,
fatty foods, can cause weight gain. Most people who develop diabetes are
overweight. Scientists do not fully understand why obesity increases someone's
chances of developing diabetes, but they believe obesity is a major factor
leading to type 2 diabetes. Current research should help explain why the
disorder occurs and why obesity is such an important risk factor.
A major
cause of diabetes is insulin resistance. Scientists are still searching for the
causes of insulin resistance, but they have identified two possibilities. The
first could be a defect in insulin receptors on cells. Like an appliance that
needs to be plugged into an electrical outlet, insulin has to bind to a
receptor to function. Several things can go wrong with receptors. There may not
be enough receptors for insulin to bind to, or a defect in the receptors may
prevent insulin from binding.
A second
possible cause involves the process that occurs after insulin plugs into the
receptor. Insulin may bind to the receptor, but the cells don't read the signal
to metabolize the sugar. Scientists are studying cells to see why this might
happen.
Points to
Remember
- In people with type 2 diabetes, insulin doesn't lower blood sugar, a condition called insulin resistance.
- Obesity is a risk factor for diabetes.
Who Develops Type 2 Diabetes?
Age, sex,
weight, physical activity, diet, lifestyle, and family health history all
affect someone's chances of developing type 2 diabetes. The chances that
someone will develop diabetes increase if the person's parents or siblings have
the disease. Experts now know that diabetes is more common in African
Americans, Hispanics, Native Americans, and Native Hawaiians than whites. They
believe this is the result of both heredity and environmental factors, such as
diet and lifestyle. The highest rate of diabetes in the world is in an Arizona
community of American Indians called the Pimas. While the chances of developing
diabetes increase with age, gender isn't a risk factor, although African
American women are more likely to develop diabetes than African American men.
While
people can't change family history, age, or race, it is possible to control
weight and physical fitness. A doctor can decide if someone is at risk for
developing diabetes and offer advice on reducing that risk.

- The following factors increase someone's chances of developing diabetes: obesity, family history of diabetes, and advancing age.

How come I've always believed over consupmtion of sugar(glucose) could cause, or increase one's chances of suffering from Diabetes?
ReplyDeleteThanks for the education Doc, at least now I can go about consuming sugar without fears.
Someone once told me I should go for a diabetes test coz I pee often during the day bt I don't get thirsty often?
