Difficulty swallowing is called dysphagia, and it’s a common symptom of those who have gastroesophageal reflux disease (GERD). In extreme cases, it’s also a sign of esophageal cancer. John Hopkins Medicine clarifies that if you have trouble swallowing, and it gets worse over time, you may want to see a doctor.

If you haven’t been diagnosed with GERD or another digestive disorder that causes chronic heartburn, the doctor may check for those first. Esophageal cancer is often caused by substance abuse and stomach disorders. People with these conditions may want to see a doctor.
