Risk factors

The following are risk factors for dysphagia:

• Aging. Due to natural aging and normal wear and tear on the esophagus as well as a greater risk of certain conditions, such as stroke or Parkinson's disease, older adults are at higher risk of swallowing difficulties. But dysphagia isn't considered a normal sign of aging.
• Certain health conditions. People with certain neurological or nervous system disorders are more likely to have difficulty swallowing.
