<p>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.</p> <p>Anyone can have a swallowing disorder, but it is more likely in the elderly. It often happens because of other conditions, including</p> <ul> <li> Nervous system disorders, such as Parkinson's disease and cerebral palsy</li> <li> Problems with your <a href='https://medlineplus.gov/esophagusdisorders.html'>esophagus,</a> including <a href='https://medlineplus.gov/gerd.html'>GERD</a> (gastroesophageal reflux disease)</li> <li> Stroke</li> <li> Head or spinal cord injury</li> <li> Cancer of the <a href='https://medlineplus.gov/headandneckcancer.html'>head, neck</a>, or <a href='https://medlineplus.gov/esophagealcancer.html'>esophagus</a></li> </ul> <p>Medicines can help some people, while others may need surgery.
