Difficulty swallowing, also known as dysphagia, can be caused by a variety of factors. It can be a result of medical conditions such as stroke, Parkinson's disease, multiple sclerosis, or gastroesophageal reflux disease (GERD). Certain medications, radiation therapy, and surgical procedures can also cause dysphagia. Risk factors for dysphagia include aging, neurological disorders, and certain lifestyle factors such as smoking and heavy alcohol consumption. It is important to seek medical attention if you are experiencing difficulty swallowing, as it can lead to complications such as aspiration pneumonia.
