diverticulitis : most common ~ 60%
colorectal cancer (CRC) : ~ 20%
Crohns disease : ~ 10%
radiotherapy
appendicitis

According to the DSM-5, if the Adjustment disorder lasts less than six months, then it may be considered acute. If it lasts more than six months, it may be considered chronic. Moreover, the symptoms cannot last longer than six months after the stressor(s), or its consequences, have terminated. : 679  However, the stress-related disturbance does not only exist as an exacerbation of a pre-existing mental disorder.Unlike major depression, the disorder is caused by an outside stressor and generally resolves once the individual is able to adapt to the situation. The condition is different from anxiety disorder, which lacks the presence of a stressor, or post-traumatic stress disorder and acute stress disorder, which usually are associated with a more intense stressor. Suicidal behavior is prominent among people with Adjustment disorder of all ages, and up to one-fifth of adolescent suicide victims may have an adjustment disorder. Bronish and Hecht (1989) found  that 70% of a series of patients with Adjustment disorder attempted suicide immediately before their index admission and they remitted faster than a comparison group with major depression. Asnis et al. (1993) found that Adjustment disorder patients report persistent ideation or suicide attempts less frequently than those diagnosed with major depression. According to a study on 82 Adjustment disorder patients at a clinic, Bolu et al. (2012) found that 22 (26.8%) of these patients were admitted due to suicide attempt, consistent with previous findings. In addition, it was found that 15 of these 22 patients chose suicide methods that involved high chances of being saved.
