(BlackDoctor.org) — WHAT IS DIABETES?
• Diabetes is a group of diseases
marked by high levels of blood glucose resulting from defects in insulin
production, insulin action, or both. Diabetes can lead to serious complications
and premature death, but people with diabetes can take steps to control the
disease and lower the risk of complications.

• Diabetes is one of the leading causes of death and disability in the
United States. Total health care and
related costs for the treatment of
diabetes run about $132 billion annually.

WHAT ARE THE DIFFERENT TYPES OF DIABETES?
• Type 1 diabetes (formerly
called juvenile diabetes) results when the body’s immune system attacks and
destroys its own insulin-producing beta cells in the pancreas. People with type
1 diabetes must have insulin delivered by injection or a pump. Symptoms of type
1 diabetes – increased thirst and urination, constant hunger, weight loss,
blurred vision, and extreme fatigue – usually develop over a short period of
time. If type 1 diabetes is not diagnosed and treated, a person can lapse into a
life-threatening coma. Type 1 diabetes accounts for 5% to 10% of all diagnosed
cases of diabetes.

• Type 2 diabetes (formerly called adult-onset diabetes) occurs when the
body does not make enough insulin or cannot use the insulin it makes
effectively. This form of diabetes usually develops in adults over the age of 40
but is becoming more prevalent in younger age groups including children and
adolescents. The symptoms of type 2 diabetes – feeling tired or ill, unusual
thirst, frequent urination especially at night, weight loss, blurred vision,
frequent infections, and slow-healing wounds – may develop gradually and may not
be as noticeable as in type 1 diabetes. Some people have no symptoms.Type 2
diabetes accounts for about 90% to 95% of all diagnosed cases of diabetes. The
following factors increase a person’s chances of having type 2 diabetes: a
family history of diabetes, being a member of an ethnic group such as African
Americans, being overweight or obese, having had diabetes while pregnant
(gestational diabetes), having high blood pressure, having abnormal cholesterol
(lipid) levels, and not getting enough physical activity.

• Gestational diabetes develops during pregnancy. Women who have had
gestational diabetes have a 20 to 50 percent chance of developing diabetes,
mostly type 2, in the next 5 – 10 years.

HOW MANY AFRICAN AMERICANS HAVE DIABETES?
• 3.2 million African
Americans ages 20 years and older (or 13.3 percent) have diabetes, one-third of
whom are undiagnosed.
• On average, African Americans are 1.8 times more
likely to have diabetes as non-Hispanic whites of similar age.

WHAT IS THE LINK BETWEEN CARDIOVASCULAR DISEASE AND DIABETES?

Cardiovascular disease is the leading cause of death for people with diabetes —
accounting for about 65 percent of all deaths.
• People with diabetes are 2
to 4 times more likely to have heart disease or suffer a stroke than people
without diabetes.
• People with type 2 diabetes have the same high risk for
heart attack as people without diabetes who already have had a heart
attack.
• About 73 percent of people with diabetes also have high blood
pressure.
• Smoking doubles the risk for heart disease in people with
diabetes.

WHAT CAN AFRICAN AMERICANS DO TO PREVENT HEART DISEASE OR STROKE
AND
OTHER DIABETES COMPLICATIONS?
• Diabetes is a self-managed disease.
People with diabetes must take responsibility for their day-to-day care.

The chances of having diabetes complications can be reduced or delayed
significantly by keeping blood glucose (blood sugar), blood pressure, and
cholesterol levels (called the ABCs of Diabetes) in the target range. The
National Diabetes Education Program (NDEP) recommends the following targets for
reducing risk of heart disease and stroke for people with diabetes:

A1C (Blood Glucose)
Less than 7 percent
(check at least twice a
year)
Blood Pressure
Less than 130/80 mmHg
(check every doctor’s
visit)
Cholesterol (LDL)
Less than 100 mg/dl
(check once a year)

• People with diabetes can manage their disease by eating healthy foods,
being physically active, taking diabetes medicine as prescribed, and testing
blood glucose levels.
• Community education and support programs can help
people with diabetes and their families to manage their diabetes.
CAN TYPE 2
DIABETES BE PREVENTED?

• YES! The Diabetes Prevention Program (DPP), an important trial
sponsored by the National Institutes of Health, showed that type 2 diabetes can
be delayed or prevented in overweight adults with prediabetes, including African
Americans. Pre-diabetes is a condition where blood glucose levels are higher
than normal, but not yet high enough for a diagnosis of diabetes.
• Risk
factors for pre-diabetes are the same as those listed for type 2 diabetes.

To prevent diabetes, the people who participated in the DPP study:
Lost 5 to
7 percent of their body weight (that’s 10 to 15 pounds in a person who weighs
200 pounds).
Were physically active for 30 minutes a day, 5 days a week. Most
participants chose brisk walking.
Made healthier food choices and limited the
amount of calories and fat in their diet.

Suffering From Constipation

Are you suffering Constipation

Constipation is passage of small amounts of hard, dry bowel movements,
usually fewer than three times a week. People who are constipated may find it
difficult and painful to have a bowel movement. Other symptoms of constipation
include feeling bloated, uncomfortable, and sluggish.

Many people think they are constipated when, in fact, their bowel movements
are regular. For example, some people believe they are constipated, or
irregular, if they do not have a bowel movement every day. However, there is no
right number of daily or weekly bowel movements. Normal may be three times a day
or three times a week depending on the person. Also, some people naturally have
firmer stools than others.

At one time or another, almost everyone gets constipated. Poor diet and lack
of exercise are usually the causes. In most cases, constipation is temporary and
not serious. Understanding its causes, prevention, and treatment will help most
people find relief.

Who gets constipated?

According to the 1996 National Health Interview Survey, about 3 million
people in the United States have frequent constipation. Those reporting
constipation most often are women and adults age 65 and over. Pregnant women may
have constipation, and it is a common problem following childbirth or
surgery.

Constipation is one of the most common gastrointestinal complaints in the
United States, resulting in about 2 million doctor visits annually. However,
most people treat themselves without seeking medical help, as is evident from
the millions of dollars Americans spend on laxatives each year.

What causes constipation?

To understand constipation, it helps to know how the colon (large intestine)
works. As food moves through the colon, it absorbs water while forming waste
products, or stool. Muscle contractions in the colon push the stool toward the
rectum. By the time stool reaches the rectum, it is solid because most of the
water has been absorbed.

The hard and dry stools of constipation occur when the colon absorbs too much
water or if the colon’s muscle contractions are slow or sluggish, causing the
stool to move through the colon too slowly. Common causes of constipation
are

  • not enough fiber in the diet
  • not enough liquids
  • lack of exercise
  • medications
  • irritable bowel syndrome
  • changes in life or routine such as pregnancy, older age, and travel
  • abuse of laxatives
  • ignoring the urge to have a bowel movement
  • specific diseases such as stroke (by far the most common)
  • problems with the colon and rectum
  • problems with intestinal function (chronic idiopathic constipation)

Not Enough Fiber in the Diet

The most common cause of constipation is a diet low in fiber found in
vegetables, fruits, and whole grains and high in fats found in cheese, eggs, and
meats. People who eat plenty of high-fiber foods are less likely to become
constipated.

Fiber—both soluble and insoluble—is the part of fruits, vegetables, and
grains that the body cannot digest. Soluble fiber dissolves easily in water and
takes on a soft, gel-like texture in the intestines. Insoluble fiber passes
through the intestines almost unchanged. The bulk and soft texture of fiber help
prevent hard, dry stools that are difficult to pass.

According to the National Center for Health Statistics, Americans eat an
average of 5 to 14 grams of fiber daily,* short of the 20 to 35 grams
recommended by the American Dietetic Association. Both children and adults eat
too many refined and processed foods from which the natural fiber has been
removed.

A low-fiber diet also plays a key role in constipation among older adults,
who may lose interest in eating and choose convenience foods low in fiber. In
addition, difficulties with chewing or swallowing may force older people to eat
soft foods that are processed and low in fiber.

Not Enough Liquids

Liquids like water and juice add fluid to the colon and bulk to stools,
making bowel movements softer and easier to pass. People who have problems with
constipation should drink enough of these liquids every day, about eight 8-ounce
glasses. Liquids that contain caffeine, like coffee and cola drinks, and alcohol
have a dehydrating effect.

Lack of Exercise

Lack of exercise can lead to constipation, although doctors do not know
precisely why. For example, constipation often occurs after an accident or
during an illness when one must stay in bed and cannot exercise.

Medications

Some medications can cause constipation. They include

  • pain medications (especially narcotics)
  • antacids that contain aluminum and calcium
  • blood pressure medications (calcium channel blockers)
  • antiparkinson drugs
  • antispasmodics
  • antidepressants
  • iron supplements
  • diuretics
  • anticonvulsants

Irritable Bowel Syndrome (IBS)

Some people with IBS, also known as spastic colon, have spasms in the colon
that affect bowel movements. Constipation and diarrhea often alternate, and
abdominal cramping, gassiness, and bloating are other common complaints.
Although IBS can produce lifelong symptoms, it is not a life-threatening
condition. It often worsens with stress, but there is no specific cause or
anything unusual that the doctor can see in the colon.

Changes in Life or Routine

During pregnancy, women may be constipated because of hormonal changes or
because the heavy uterus compresses the intestine. Aging may also affect bowel
regularity because a slower metabolism results in less intestinal activity and
muscle tone. In addition, people often become constipated when traveling because
their normal diet and daily routines are disrupted.

Abuse of Laxatives

Myths about constipation have led to a serious abuse of laxatives. This is
common among people who are preoccupied with having a daily bowel movement.

Laxatives usually are not necessary and can be habit-forming. The colon
begins to rely on laxatives to bring on bowel movements. Over time, laxatives
can damage nerve cells in the colon and interfere with the colon’s natural
ability to contract. For the same reason, regular use of enemas can also lead to
a loss of normal bowel function.

Ignoring the Urge to Have a Bowel Movement

People who ignore the urge to have a bowel movement may eventually stop
feeling the urge, which can lead to constipation. Some people delay having a
bowel movement because they do not want to use toilets outside the home. Others
ignore the urge because of emotional stress or because they are too busy.
Children may postpone having a bowel movement because of stressful toilet
training or because they do not want to interrupt their play.

Specific Diseases

Diseases that cause constipation include neurological disorders, meta
