Abstract
Recurrent abdominal pain is a common reason for consultation in Gastroenterology. The differential diagnosis includes hereditary angioedema (HAE), a rare disorder characterized by recurrent episodes of angioedema, without urticaria or pruritus, which most often affects the skin, but also mucosal tissues of the gastrointestinal tract, triggered by diverse factors such as infections, trauma, surgery, drugs, or stress. It is a disease with a difficult diagnosis due to its heterogeneous and transitory clinical features, so having a clinical suspicion in the appropriate context would allow the administration of a specific treatment and avoid unnecessary examinations. We present the case of a 19-year-old male followed-up for recurrent abdominal pain that, after numerous microbiological, endoscopic, and radiological examinations, complement tests were requested, obtaining low levels of C4 with increased levels of C1 inhibitor and reduced functional activity, being diagnosed with HAE type II.
