From the Guidelines

Red flags for gastroesophageal reflux disease (GERD) that necessitate immediate medical attention include dysphagia, bleeding, anemia, weight loss, or recurrent vomiting, as these symptoms may indicate severe complications such as esophageal cancer or bleeding lesions. These symptoms are highlighted in the clinical guidelines for the management of GERD, emphasizing the importance of upper endoscopy in patients presenting with such alarm symptoms 1. Key red flags to watch out for include:

  • Dysphagia, which may indicate esophageal stricture or cancer
  • Bleeding, anemia, or iron deficiency, suggesting chronic bleeding from GERD-related erosions
  • Weight loss, which could be a sign of malignancy or severe esophageal disease
  • Recurrent vomiting, potentially leading to dehydration, electrolyte imbalances, or aspiration pneumonia
  • Symptoms persisting despite adequate medication use, indicating possible treatment failure or underlying complications It is crucial for patients experiencing these symptoms to seek medical evaluation promptly, rather than continuing self-treatment, to allow for early detection and intervention of serious complications 1. Regular follow-up is also essential for patients with chronic GERD to monitor for the development of these concerning symptoms and to adjust treatment plans as necessary.
