What are feeding and swallowing disorders?
Feeding disorders include difficulties with gathering food and getting ready to suck, chew, or swallow it. For example, a child who cannot pick up food and get it to her mouth or cannot completely close her lips to keep food from falling out of her mouth may have a feeding disorder. Feeding disorders occur in 25-35% of developmentally normal children and 40-70% of children with developmental disabilities and/or chronic medical conditions.
Swallowing disorders (dysphagia) can occur at different stages in the swallowing process – oral phase (in the mouth – moving food from side to side, chewing, biting, closing the lips to keep food inside the mouth, moving the jaw to facilitate chewing, tongue propelling the food down to the throat), pharyngeal phase (initiating the swallow, closing the airway to prevent food from entering it while pushing food down to the esophagus) or the esophageal phase (opening/closing of the feeding tube in the throat and squeezing food from the esophagus to the stomach).
Feeding and swallowing disorders can also be sensory or behavioral in nature. Children may have hyposensitive (reduced awareness of non-nutritive and nutritive stimuli in the mouth, heightened sensory threshold to oral input” or hypersensitive (heightened awareness of non-nutritive and nutritive stimuli in the mouth, decreased sensory threshold to oral input) responses to food experiences. Sensory-based feeding experiences may affect any of the senses – smell of different foods, touching and tolerating different textures of food, visually tolerating different foods and/or tasting different types of food (temperature, textures). Behavioral feeding disorders usually have underlying issues that stem from somewhere else e.g. Bad habits/desperation, poor limit setting, lack of mealtime structure and routine. passive eating with distractions, inconsistent expectations regarding eating.

Diagnosis and Treatment
If you suspect that your child is having difficulty eating, contact your pediatrician immediately. Feeding disorders are diagnosed and treated by a group of professionals (speech-language therapist, occupational therapist, dietician and others). A speech-language therapist who specializes in treating children with feeding and swallowing disorders will assess your child and ask questions about your child’s medical history, development, and symptoms, look at the strength and movement of the muscles involved in swallowing, observe feeding to see your child’ s posture, behavior, and oral movements during eating and drinking and recommend special tests, if necessary, to evaluate swallowing. Depending on the cause and symptoms of the feeding disorder, the team will then make recommendations on how to improve your child’s feeding and swallowing.
