swallowing disorders

difficulty in swallowing may be caused by foreign body obstruction, by inflammation of the lining or by a defect in nervous control. The nerves involved are the sensory and motor branches of the trigeminal nerve, the hypoglossal, the facial and the glossopharyngeal nerves. Called also dysphagia.

swallowing reflex

begins as soon as the bolus of ingesta approaches the entry to the pharynx. In a series of reflex actions: breathing is halted, the soft palate elevates and closes the entrance to the nasal cavities, the tongue is clamped into the fauces, closing the exit from the pharynx back into the mouth, the epiglottis closes off the larynx, the pharynx contracts and forces the bolus into the esophagus, peristalsis-like movements in the esophagus carry the food to the cardia which relaxes and the food is propelled into the stomach. Called also palatal reflex.

repeated swallowing

a sign of partial esophageal obstruction.

Patient discussion about Deglutition disorders.

Q. Why is it hard to swallow when you have a sore throat? I was sick last week. I had a sore throat pain in my neck and fever. the most annoying symptom that i had was pain during sallowing. what is the source of that pain, and what can I do to ease it next time?

A. When you have an inflammation in your body, the sick area hurts when its palpated. when your neck is inflamed, you have a pain in the neck. when the inside part of the neck is inflamed you have tonsillitis.
When you eat something, it touches your inside of the neck, and if it's inflamed it will be painful.
The good news is that you can treat this pain in the same way you treat other inflammatory pain - hot (NOT boiling) tea.

Q. every time my friend eat, before she swallow it she gets severe heartburns and nausea. what causes this

A. She could be suffering from gastric acid problems and should try taking anti-acid medications (after consulting a doctor, of course). Also there's a simple test that can be done for a bacteria called H.pylori that makes the stomach produce more acid, and by taking antibiotics this problem resolves.
