It is clear from the passage that ulcer----.
An ulcer is an erosion of the top layer of cells from
an area, such as the wall of the stomach or
duodenum. This erosion leaves the underlying
layers of cells unprotected and exposed to gastric
juices. The erosion may proceed until the gastric
juices reach the capillaries that feed the area,
leading to bleeding, and reach the nerves, causing
pain. If Gl bleeding is excessive, iron deficiency
may develop. If the erosion penetrates all the way
through the Gl lining, a life-threatening infection
can develop. Many people naively believe that an
ulcer is caused by stress or spicy foods, but this is
not the case - at least not at first. The stomach
lining in a healthy person is well protected by its
mucous coat. What, then, causes ulcers to form?
Three major causes of ulcers have been identified:
bacterial infection with Helicobacter pylori, the use
of certain anti-inflammatory drugs such as
ibuprofen and naproxen, and disorders that cause
excessive gastric acid secretion. The cause of the
ulcer dictates the type of drug treatment. For
example, people with ulcers caused by infection
receive antibiotics, whereas those with ulcers
caused by drugs discontinue their use. In addition,
all treatment plans aim to relieve pain, heal the
ulcer, and prevent recurrence.
