Other factors also seem to contribute to ulcer formation.

The size, number, location, healing time and periodicity between episodes of ulcer formation are all dependent upon the subtype of aphthous stomatitis (see classification).

Before considering, in detail, the treatment of peptic ulcers by using drugs, it is necessary to consider the factors that lead to ulcer formation.

These findings suggest that loss of intercellular communication via gap junctions is associated with gastric ulcer formation.

We have therefore studied gastric secretion in this model to test whether ulcer formation is associated with an increased acid-pepsin attack.

These studies therefore show that the ulcer formation is not due to hypersecretion of acid or pepsin.

After 12 weeks of treatment, a device called an endoscope was then used to examine their gastrointestinal tract for signs of ulcer formation.

This is a painful condition marked by swelling and ulcer formation in the mouth or lining of the digestive tract.

There may also be impaired wound healing or ulcer formation because of the immunosuppressive effects.

Vitamin C deficiency may lead to scurvy which impairs wound healing, which can contribute to ulcer formation.
