| Ulcerative Colitis
Ulcerative
colitis is a chronic, recurring disease of the large bowel. The large
bowel (colon) is the 5 to 6 foot segment of intestine that begins in the
right-lower abdomen, extends upward and then across to the left side,
and downward to the rectum. It dehydrates the liquid stool that enters
it and stores the formed stool until a bowel movement occurs.
When ulcerative colitis affects the colon, inflammation and ulcers, or
sores, form in the lining of the colon. The disease may involve the entire
colon (pancolitis), only the rectum (ulcerative proctitis) or, more commonly,
somewhere between the two.
Causes
The cause of ulcerative colitis is unknown. Some experts believe there
may be a defect in the immune system in which the body's antibodies actually
injure the colon. Others speculate that an unidentified microorganism
or germ is responsible for the disease. It is probable that a combination
of factors, including heredity, may be involved in the cause.
Who Develops Ulcerative Colitis?
The disorder can occur in both sexes, all races and all age groups. It
is a disease that usually begins in young people.
Symptoms
The disorder typically begins gradually, with crampy abdominal pain and
diarrhea that is sometimes bloody. In more severe cases, diarrhea is very
severe and frequent. Loss of appetite and weight loss occur. The patient
may become weak and very sick. When the disease is localized to the rectum,
the symptoms are rectal urgency and passage of small amounts of bloody
stool. Usually the symptoms tend to come and go, and there may be long
periods without any symptoms at all. Usually, however, they recur.
Diagnosis
Diagnosis of ulcerative colitis can be suspected from the symptoms.
Certain blood and stool tests are performed to rule out an infection that
can mimic the disorder. A visual examination of the lining of the rectum
and lower colon (sigmoidoscopy) or the entire colon (colonoscopy) is always
required. This exam typically reveals a characteristic pattern. Small,
painless biopsies are taken which show certain features of ulcerative
colitis. A barium enema x-ray of the colon may be needed at some point
during the course of the disease.
Complications
Most patients with this disease respond well to treatment and go about
their lives with few interruptions. However, some attacks may be quite
severe, requiring a period of bowel rest, hospitalization and intravenous
treatment. In rare cases, emergency surgery is required. The disease can
affect nutrition causing poor growth during childhood and adolescence.
Liver, skin, eye or joint (arthritis) problems occasionally occur, even
before the bowel symptoms develop. Other problems can include narrowing
and partial blocking of the bile ducts which carry bile from the liver
to the intestine. Fortunately, there is much that can be done about all
of these complications.
In
long-standing ulcerative colitis, the major concern is colon cancer. The
risk of developing colon cancer increases significantly when the disorder
begins in childhood, has been present for 8 to 10 years, or when there
is a family history of colon cancer. In these situations, it is particularly
important to perform regular and thorough surveillance of the colon, even
when there are no symptoms. Analysis of colon biopsies performed during
colonoscopy can often predict if colon cancer will occur. In these cases,
preventive surgery is recommended.
Treatment
There are several types of medical treatments available:
Cortisone, Steroids, Prednisone -- These powerful drugs usually
provide highly effective results. A high dose is often used initially
to bring the disorder under control. Then the drug is tapered to low,
maintenance doses, even to a dose every other day. These medications are
given by pill, enema or intravenously during an acute attack. In time,
the physician will usually try to discontinue these drugs because of potential
long-term, adverse side effects.
Other Anti-inflammatory Drugs -- There are increasing numbers
of these drugs available. They can be given by pill or enema. The generic
and trade names of some of these drugs are sulfasalazine (Azulfidine),
olsalazine (Dipentum), mesalamine (Asacol, Pentasa and Rowasa) and balsalazide
(Colazal).
Immune System Suppressors -- An overactive immune system is probably
important in causing ulcerative colitis. Certain drugs such as azathioprine
(Imuran), 6-MP (Purinethol), cyclosporine (Neoral, Sandimmune), and methotrexate
(Rheumatrex) suppress the immune system and at times are effective.
Diet and Emotions
There are no foods known to injure the bowel. However, during an acute
phase of the disease, bulky foods, milk, and milk products can increase
diarrhea and cramping. Generally, the patient is advised to eat a healthy,
well-balanced diet with adequate protein and calories. A multiple vitamin
is often recommended. Iron may be prescribed if anemia is present.
Stress and anxiety may aggravate symptoms of the disorder, but are not
believed to cause it or make it worse. Any chronic disease can produce
a serious emotional reaction in the patient. This can usually be handled
through discussion with the physician. There are excellent support groups
available in most communities. The Crohn's
and Colitis Foundation is one of them.
Surgery
For patients with longstanding disease that is difficult or impossible
to control with medicine, surgery is a welcomed option. In these rare
cases, the patient's lifestyle and general health have been significantly
affected. Surgical removal of the colon cures the disease and returns
good health and a normal lifestyle to the patient. In the past a permanent
bag, or ileostomy, was required for this surgery. Advances in surgery
now can avoid this problem. The colon is removed and a pouch or reservoir
is created from the small intestine. Three to six liquid bowel movements
occur daily. Most patients are extremely pleased with this new surgery.
Summary
Most people with ulcerative colitis lead normal, active lives with few
restrictions. Although there is no cure (except by surgery), the disorder
can be managed with present treatments. For a few patients, the course
of the disease may be more difficult and complicated, requiring more testing
and intensive therapy. Surgery sometimes is required. In all cases, follow-up
care with the physician is essential to monitor the disease and prevent
and treat any complications that arise.
