Excess Stress
While there is no scientific evidence linking emotional or mental stress to ulcers, experts believe that stress increases the likelihood of a stomach ulcer. Stress, particularly prolonged stress, can affect the production of stomach acid. It can cause increased stomach acid release and increase inflammation.
Although stress alone can, in some cases, cause ulcers, stress is most often associated with a bacterial infection or the use of anti-inflammatory drugs that further leads to ulcers. Chronic stress can even prevent the healing of existing ulcers.
