why do people with gastric ulcers get weight loss?

[sarah90222]

is it because of the loss in apetite? if so why do they have a loss in apetite? is it because of the epigastric pain it causes?

or maybe it is because of the acid that goes into the duodenum and so limiting the enxymes which work there?

It is mostly due to pain and discomfort related to eating: people with severe enough ulcers simply cannot eat enough to gain/maintain their bodyweight.
