5- Constipation
Constipation is the infrequent and difficult passage of
stools. It is the most common digestive complaint in the United States,
resulting in approximately two million doctor visits annually. Women, especially
those who are pregnant, and adults aged 65 and older are most commonly
affected. Virtually everyone experiences an occasional bout of constipation
that resolves itself with dietary changes and time. Although uncomfortable, it
is usually not dangerous. However, it can lead to other problems such as
hemorrhoids or signal an underlying health condition.
Although bowel movement frequency varies
greatly for each person, if more than three days pass without a bowel movement,
the contents in the intestines may harden, making it difficult or even painful
to pass. Straining during bowel movements or the feeling of incomplete emptying
also may be considered constipation. Constipation is a symptom, not a disease, and can be caused by
many factors. The most common are poor diet and lack of exercise. Other causes
include irritable bowel syndrome, pregnancy, laxative abuse, travel, specific
diseases, hormonal disturbances, loss of body salts and nerve damage. A variety
of medications also can cause constipation, such as pain medications,
especially narcotics, antacids that contain aluminum, antispasmodic drugs,
antidepressant drugs, tranquilizers, iron supplements, anticonvulsants for
epilepsy, antiparkinsonism drugs and antihypertensive calcium channel blockers.
Each individual may experience symptoms of
constipation differently. However, some of the most common symptoms include:
- The inability to have a bowel movement for
several days or passing hard, dry stools
- Abdominal bloating, cramps or pain
- Decreased appetite
- Lethargy
Your doctor will ask about
your medical history, perform a physical examination and order routine blood,
urine and stool tests. Other diagnostic tests used to make a diagnosis of
constipation include sigmoidoscopy and colonoscopy.
Sigmoidoscopy
For a sigmoidoscopy, the doctor uses a special
instrument called a colonoscope, which is a long, flexible tube that is about
as thick as your index finger and has a tiny video camera and light on the end,
to exam your rectum and lower part of your colon. During the procedure,
everything will be done to help you be as comfortable as possible. Your blood
pressure, pulse and the oxygen level in your blood will be carefully monitored.
Colonoscopy
Colonoscopy is used to evaluate symptoms such
as abdominal pain, bloody bowel movements, altered bowel habits such as
constipation or diarrhea, and weight loss. This test is similar to
sigmoidoscopy, but the doctor looks at the entire colon, rather than just the
left side. The term "colonoscopy" means looking inside the colon.
Colonoscopy is a procedure performed by a gastroenterologist, a well-trained
specialized doctor.
Colonoscopy also is
performed using a colonoscope, which is a long, flexible tube that is about as
thick as your index finger and has a tiny video camera and light on the end, to
exam your rectum and lower part of your colon. During the procedure, everything
will be done to help you be as comfortable as possible. Your blood pressure,
pulse and the oxygen level in your blood will be carefully monitored.
By adjusting the various controls on the colonoscope,
the gastroenterologist can safely maneuver the instrument to carefully examine
the inside lining of the colon from the anus to the cecum. The colonoscope
contains a channel that allows instruments to be passed in order to take tissue
or stool samples, remove polyps and provide other therapy. The high quality
picture from the colonoscope, shown on a TV monitor, provides a clear, detailed
view of the colon. It provides a more precise examination than X-ray studies.
Your doctor will do a
rectal exam with a gloved, lubricated finger; then the lubricated colonoscope
will be gently inserted. As the scope is slowly and carefully passed, you may
feel as if you need to move your bowels, and because air is introduced to help
advance the scope, you may feel some cramping or fullness. Generally, however,
there is little or no discomfort. Occasionally, some abdominal pressure, which
may be provided by your nurse, or a change in position may be needed to avoid
looping of the colonoscope within the abdomen. Your doctor will advance the
scope until he or she reaches the beginning of the colon, called the cecum.
After reaching this point, the scope is then carefully withdrawn while a
thorough exam of the colon is performed. At this point in the exam, your doctor
will use the colonoscope to look closely for any polyps or other problems that
may require evaluation, diagnosis or treatment. The procedure typically takes
between 10 and 15 minutes.
Treatment for constipation depends on the
cause, severity and duration. However, in most cases, dietary and lifestyle
changes will help relieve symptoms and prevent the condition altogether. A
well-balanced diet that includes fiber-rich foods, such as unprocessed bran,
whole-grain bread and fresh fruits and vegetables, is recommended. Ideally, you
should consume 20 to 35 grams of fiber each day. In addition, drinking plenty
of fluids and exercising regularly helps stimulate intestinal activity.
Although most people who
are mildly constipated do not need laxatives and an overuse of laxatives can
actually cause constipation, they may be recommended for those who are still
suffering from the condition even after making diet and lifestyle changes. Your
doctor is best qualified to determine when a laxative is needed and which type.
