The Stomach is an organ which has the primary function of breaking up
food into smaller pieces. This process is called digestion. The stomach does this
by using acid, enzymes, and mechanical forces. Acid and enzymes break down and dissolve
food. The mechanical force of the stomach helps to mix the enzymes and acid with
the food and break large pieces into smaller pieces. Once food is broken up it is
passed on into the small intestine for absorption.
Diseases of the Stomach
The following is a brief discussion of
some problems that can arise in the stomach. It is for information only and is not
complete. You should always talk to your physician about the diagnosis or treatment
of any medical condition.
Gastric Ulcer- Ulcers are cuts
or abrasions of the stomach. The most common causes of ulcers are Helicobacter Pylori
and non-steroidal anti-inflammatory drugs (NSAIDs). Helicobacter Pylori is a bacteria
that can live in the stomach. NSAIDs include aspirin most over the counter pain
medications. Ulcers may cause pain but can also be asymptomatic. The biggest risk
of an ulcer is bleeding which may present with vomitting up blood or passing large
amounts of blood or melana (black tarry stool) being from the rectum. Blood loss
from ulcers is significant and these symptoms require immediate medical attention.
Gastric ulcers can also in some cases occur with stomach cancer and should be followed
up to document healing.
Gastritis- Gastritis refers to
inflammation in the stomach. The same things that cause ulcers can cause gastritis.
It can also be caused by other things such as bile and poor movement of material
through the stomach. It often has no symptoms but may cause abdominal pain.
Polyps- Polyps are small growths
which come off of the stomach wall. There are many types of polyps which can be
present in the stomach. Most stomach polyps are benign. If you have stomach polyps
you should discuss them with your physician to determine what needs to be done.
Gastric Cancer- Gastric cancer
refers to cancer of the stomach. The most common gastric cancer is adenocarcinoma.
There are a variety of other stomach cancers which are less common. The symptoms
of stomach cancer can include abdominal pain, nausea, vomiting, weight loss, feeling
full quickly when eating, vomiting up blood, or passing blood or black tarry stools
per rectum. You should rely on your physicians for information on diagnosis and
treatment of stomach cancer.
Gastroparesis- Gastroparesis
is a condition where the stomach does not mechanically break up food as well. This
results in food staying in the stomach longer before being passed on to the small
bowel. It is more common in people with diabetes and people who have had surgery
on their stomach. In very severe cases on rare occasions a bezoar or giant
indigestible
food ball may form in the stomach. Patients with gastroparesis are more likely to
reflux acid up into their esophagus. The symptoms of gastroparesis can include abdominal
fullness, abdominal bloating, abdominal pain, nausea, vomiting, and heartburn.
