Flushing Disorders Associated with Gastrointestinal Symptoms: Part 2, Systemic Miscellaneous Conditions.

Abstract

Flushing disorders with involvement of the gastrointestinal tract represent a heterogeneous group of conditions. In part 1 of this review series, neuroendocrine tumors (NET), mast cell activation disorders (MCAD), and hyperbasophilia were discussed. In this section we discuss the remaining flushing disorders which primarily or secondarily involve the gastrointestinal tract. This includes dumping syndrome, mesenteric traction syndrome, rosacea, hyperthyroidism and thyroid storm, anaphylaxis, panic disorders, paroxysmal extreme pain disorder, and food, alcohol and medications. With the exception of paroxysmal pain disorders, panic disorders and some medications, these disorders presents with dry flushing. A detailed and comprehensive family, social, medical and surgical history, as well as recognizing the presence of other systemic symptoms are important in distinguishing the different disease that cause flushing with gastrointestinal symptoms.
