Most commonly manifest as difficult and/or painful swallowing, nausea, vomiting, diarrhea and constipation. In rare cases, lesions caused by medications may be complicated by bleeding, strictures and perforations and can manifest in all segments of the gastrointestinal tract (GIT). The diagnosis is made from a detailed medical history and clinical examination inter alia. and best confirmed by proximal or distal endoscopy.
