Swallowing disorders can be caused by various factors, including:
- Neurological Issues: Conditions such as stroke, Parkinson's disease, or multiple sclerosis can affect the nerves that control the swallowing muscles.
- Infections or Inflammations: Throat infections or esophageal inflammations can obstruct the passage of food.
- Tumors: Tumors in the throat or esophagus may block or narrow the digestive tract.
- Smoking or Alcohol Consumption: These can affect the swallowing process by causing swelling or dryness in the throat.
