If you have a swallowing disorder, you may have difficulty or pain when swallowing. Some people cannot swallow at all. Others may have trouble swallowing liquids, foods, or saliva. This makes it hard to eat. Often, it can be difficult to take in enough calories and fluids to nourish your body.
Anyone can have a swallowing disorder, but it is more common in older adults. It often happens because of other conditions, including
Nervous system disorders, such as Parkinson's disease and cerebral palsy
Problems with your esophagus, including GERD (gastroesophageal reflux disease)
Stroke
Head or spinal cord injury
Cancer of the head, neck, or esophagus
Medicines can help some people, while others may need surgery. Swallowing treatment with a speech-language pathologist can help. You may find it helpful to change your diet or hold your head or neck in a certain way when you eat. In very serious cases, people may need feeding tubes.
