Swallowing problems can make it difficult to clear normal secretions. This may result in the accumulation of material in the throat which can spill into the voice box, causing hoarseness, throat clearing, or cough. The following factors can contribute to swallowing problems:
- Advancing age: This will lead to decreased strength and coordination in swallowing.
- Stress: Stress leads to muscle spasm or "lump in throat." Also a nervous habit of frequent throat clearing will make the situation worse.
- Narrowing of the throat due to tumors or other conditions: This will impair the passage of food.
- Gastroesophageal reflux (GERD)
- Nerve or muscle disorders: (stroke, and muscle diseases, etc.)
