Individuals may experience mild to severe difficulties when swallowing, including: Coughing, choking or throat-clearing while eating or drinking, throat pain or discomfort, sensation of food sticking the mouth, throat or upper chest, or gurgling noises when speaking. Feeding disorder happens when an infant or child has trouble eating or refuses to eat. Feeding difficulties may be an effect of underlying medical complications, but may also be related to sensory and behavioral issues. Symptoms of a feeding disorder may include: refusal to eat, trouble swallowing, taking longer than normal to eat or drink, vomiting, choking, gagging, and behavioral difficulties.
