What is Ulcerative
Colitis? Some informations of ulcerative ( courtecy;- medicinenet.com )
What is Ulcerative Colitis?
Ulcerative
colitis is a disease in which there is chronic inflammation of the inner lining
of the colon. The inflammation can cause the lining tissue to break down,
forming ulcerations that can bleed. Inflammation can involve the entire colon
or only parts of it. Almost always, ulcerative colitis requires treatment.
Warning Sign: Abdominal Pain
The main
symptoms caused by ulcerative colitis are abdominal pain and diarrhea, usually
bloody. Symptoms vary in severity from mild to severe. The photograph shows the
typical pattern of ulcerative colitis with ulcerations covered by white pus.
Warning Sign: Weight Loss
The chronic
inflammation and symptoms of ulcerative colitis, if not controlled, have
general effects on nutrition; poor appetite, loss of weight, and poor growth in
children are common.
Other Warning Signs
Associated with
the colonic inflammation in ulcerative colitis are complications that are not a
direct result of the inflammation in the colon. Some of these complications are
generalized symptoms and signs of inflammation such as fever, fatigue, and
anemia. Others are the result of inflammation occurring outside of the colon
such as arthritis and skin sores.
Ulcerative Colitis or Crohn’s Disease?
Ulcerative
colitis is considered to be related to Crohn's disease, another chronic
inflammatory disease of the intestines (both are referred to as inflammatory
bowel disease); however, Crohn's disease, unlike ulcerative colitis, is not
limited to the colon. In fact, Crohn's disease usually involves the small intestine
or small intestine and colon although occasionally it too is limited to the
colon. Another chronic gastrointestinal disorder, irritable bowel syndrome,
shares with ulcerative colitis abdominal pain and diarrhea as its main
symptoms; however, the cause of irritable bowel syndrome is believed to be
dysfunction of the nerves and muscles of the intestines since there is no
identifiable inflammation.
Who is Affected by Ulcerative Colitis?
Ulcerative
colitis is a disease that occurs in developed nations, and is more common in
cities than in the countryside. Approximately 700,000 people in the U.S. suffer
from ulcerative colitis. Individuals with ulcerative colitis usually develop
the disease between ages 15 and 25 although the disease may begin at any age.
There seems to be a genetic component since ulcerative colitis is more common
among relatives of individuals with ulcerative colitis. Caucasians and
individuals of eastern European Jewish descent are more likely to develop
ulcerative colitis.
What Causes Ulcerative Colitis?
The cause of
ulcerative colitis is unknown, but it is believed to be somehow related to
abnormal immunologic reactions of the body to the bacteria normally found in
the colon. There is no evidence that diet is the cause of ulcerative colitis.
Diagnosing Ulcerative Colitis
The best way of
diagnosing ulcerative colitis is with colonoscopy, a procedure in which a
camera on the end of a long flexible tube is passed through the anus and into
the colon and then traverses the entire colon. Although ulcerative colitis also
can be diagnosed by barium enema, a procedure that requires X-rays of a
barium-filled colon, colonoscopy is more sensitive, that is, it identifies
lower levels of inflammation than can be identified by barium enema. Colonoscopy
also allows biopsies to be taken of the colonic lining to confirm the
diagnosis.
The Course of Ulcerative Colitis
The course of
ulcerative colitis is variable. Untreated, it usually fluctuates in severity
from mild to severe in the same individual, most often over years.
Occasionally, the disease "burns out," becoming inactive although
residual scarring usually is visible with colonoscopy.
Urgent Care for Ulcerative Colitis
During a flare
of ulcerative colitis, treatment is important to avoid complications. The most
common complication is bleeding that can lead to anemia. With a severe flare,
the colon may stop working and dilate (enlarge). If not successfully treated,
the colon may rupture and become a medical emergency. If treatment is not
successful, surgery may be necessary. Usually, the entire colon is removed.
Ulcerative Colitis and Colon Cancer
Individuals
with ulcerative colitis are at increased risk for colon cancer. The risk of
colon cancer increases as the duration of disease, and the extent of the
disease in the colon increase. To prevent colon cancer, screening colonoscopy
with biopsies are recommended on a regular basis (usually annually) in order to
detect precancerous cells so that the colon can be removed surgically before
cancer develops. Screening usually is begun approximately eight years after the
onset of the disease, the time at which the incidence of colon cancer begins to
increase.
Other Complications
Ulcerative
colitis is associated with important complications in parts of the body unconnected
with the colon. Inflammation may involve the spine and large joints
(arthritis). Serious skin ulcerations may occur. A serious liver disease,
sclerosing cholangitis, occurs in a small number of people with ulcerative
colitis. All of these complications involve inflammation and the immune system
just like in the colon. Some of these complications improve with successful
treatment of the colitis, others do not.
Medications for Ulcerative Colitis
Treatment of
ulcerative colitis aims to reduce the inflammation in the colon. The
inflammation-reducing drugs with the most extensive experience are the
aminosalicylates, drugs that are related to aspirin. If aminosalicylates are
ineffective, corticosteroids (for example, prednisone) are used. A third type
of drug that is used is immunomodulators, drugs that reduce the immune response
and thereby the inflammation. It may take several weeks to months for the drugs
to become maximally effective.
Biologic Therapies
The most recent
innovation in the treatment of ulcerative colitis is what is referred to as
biologic therapy. Biologic therapy is therapy with antibodies that are directed
against molecules that the immune system produces and that cause the inflammation.
The biologic therapy with the most experience is directed against a protein
produced by the immune system called tumor necrosis factor. The antibodies must
be given intravenously every few weeks.
Whipworm Therapy
An interesting
observation is that infection with the pig whipworm may be effective treatment
for ulcerative colitis. Scientists believe that the worms that inhabit the
colon alter the immune response and thereby reduce the inflammation. In one
study, 43% of patients with ulcerative colitis improved after ingesting pig
whipworm eggs for 12 weeks. The impetus for investigating treatment with the
whipworm came from the observation that ulcerative colitis was not common in
developing countries where intestinal parasitic diseases are common.
Surgery for Ulcerative Colitis
Despite drug
therapies, approximately one-third of people with ulcerative colitis will need
surgery to treat the inflammation, prevent or treat cancer, or to treat a
complication such as rupture of the colon. Surgery in which the entire colon is
removed cures the person of their ulcerative colitis. In the past they were
left with ileostomies, external bags into which the small intestine emptied.
Surgical techniques have been developed, however, that now allow the colon to
be removed without the need for an ileostomy.
Ulcerative Colitis in Children
Children with
ulcerative colitis that is not controlled often grow more slowly than normal,
and may end up shorter than they would have. This occurs because when there is
active inflammation, appetite is reduced and an insufficient amount of food is
eaten. It may be necessary to recommend high calorie diets or even augment the
diet with supplements. Children with psycho-social problems because of their
disease may need a therapist to help them develop strategies to cope with the
disease.
Living With UC: Reducing Flares
There are few
non-drug, controllable factors that can reduce the symptoms of ulcerative
colitis. Stress reduction is important although it probably makes the symptoms
seem less severe without actually reducing them. Of course, it is of utmost
importance for patients to take their medications regularly and not miss doses.
Although smoking can reduce the inflammation of ulcerative colitis, smoking
cannot be recommended as treatment because of its many other detrimental
effects.
Living With UC: Diet Changes
Although it has
not been found that diet has an effect on ulcerative colitis, it generally is
recommended that patients eliminate any foods that they find are making their
symptoms worse. For example, milk in people with UC who are intolerant to the
sugar in milk, lactose, may be causing gastrointestinal symptoms such as
abdominal bloating, flatulence, and diarrhea, symptoms that may overlap with
those of ulcerative colitis. Despite not being the cause of the ulcerative
colitis, eliminating milk may improve gastrointestinal symptoms in these
people. It is important to be sure that the diet is nutritionally adequate, and
this may require the assistance of a dietician.
Living With UC: Supplements
The bleeding
caused by ulcerative colitis may lead to iron deficiency anemia due to the loss
of the body's store of iron in the red blood cells that are lost into the
colon. Iron supplementation may be necessary. Medications used to treat ulcerative
colitis may reduce the absorption of nutrients such as folic acid and calcium.
Supplements of vitamins and minerals may be necessary.
Living With UC: Probiotics
Probiotics
consist of bacteria that confer a health benefit on the person who ingests them.
In general, they are bacteria that are normally found in the human intestine.
Probiotics have beneficial effects in several medical conditions. Studies have
shown that probiotics help people with ulcerative colitis maintain their
remissions. Probiotics are found in yogurts and some other foods, but the
probiotics that have been studied and found to be effective are sold separately
as supplements and are not food products. The effects of probiotics vary
greatly and depend on the exact bacteria that are present. Therefore, it is
likely that many probiotics that are sold have no beneficial effect, and,
therefore, the one that is used for treatment needs to be chosen carefully on
the basis of scientific studies.
Living With UC: Staying Hydrated
Chronic diarrhea
can lead to dehydration, particularly if individuals feel ill and are not
eating or drinking enough fluids. It is important to maintain an adequate fluid
intake. The simplest way to judge whether intake is adequate is to look at the
volume and color of urine each the day. A small amount or a dark color of the
urine suggests that the intake of water is not adequate. A suggested amount of
liquid to drink each day is half an ounce per pound of weight.
Living With UC: Relationships
Ulcerative
colitis can have a major effect on relationships, particularly intimate ones.
Issues of feeling ill or needing to visit the restroom frequently can be
socially limiting. Both of these issues can be controlled by adequate treatment
of the ulcerative colitis. Medications, for example, corticosteroids can cause
changes in mood such as depression or euphoria. Libido also can be reduced. It
is important to be open about these issues with intimate partners and with
physicians. It may be of value to see a specialist - psychologist or
psychiatrist - to help deal with the issues.
Living With UC: Travel
People with ulcerative
colitis in remission usually have no problems when traveling. If some symptoms
are present, it may be necessary to take several precautionary steps including:
·
Asking employees or use
web sites to learn where bathrooms are located in airports and other public
buildings ahead of a visit.
·
Carry a change of
underwear and moist towlettes
·
Make sure that enough
medication is taken to last the entire trip. It probably also is valuable to
take copies of prescriptions in case a visit to a medical facility is
necessary.
·
Discuss your plans for
the trip with a doctor to determine if any other steps should be taken, for
example, taking additional medications in case symptoms become problematic or a
flare of the disease occurs.
