Difficulty swallowing, also known as dysphagia, is usually a sign of a throat or esophagus problem.
Common triggers for dysphagia are malfunctioning muscles or a blockage in the throat or esophagus, says the University of Michigan.
Specific causes of dysphagia include:
- Stroke, brain or spinal cord injury.
- Nervous system conditions.
- Esophageal spasm or tumors.
- Inflammation of the esophagus.
- Gastroesophageal reflux disease.
Trouble swallowing on a regular basis may be a sign of a serious medical issue that needs prompt treatment, the school says.
