Recurrent Nausea and Vomiting with Weight Loss Associated with Hypothyroidism: Fact or Myth

Abstract

Background: Hypothyroidism is a commonly encountered endocrine disorder presenting in various clinical settings. It usually presents with classic manifestations, which are readily recognized and, therefore, easy to diagnose. However, occasionally, patients present with unusual symptoms, which becomes a challenge to diagnose. Thyroid dysfunction affects many body organs, including the gut and viscera. Studies show that intestinal motility might be affected by multiple factors, such as neuromuscular dysfunction, myopathy, or alterations in hormone receptors. Case Presentation: Here, we present the first case of a 21-year-old female student who had complaints of recurrent nausea, vomiting, loose stool, abdominal pain, and weight loss. In the second case, a 25-year-old male student presented with recurrent nausea, vomiting, loose stool, and weight loss. Their unremarkable blood routines and gastrointestinal-specific investigations failed to ascertain the diagnosis. Later, primary hypothyroidism was established by typical biochemical abnormalities. Conclusion: Thyroxine replacement treatment successfully resolved the presenting symptoms and normalized biochemical reports.
