Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for your throat is the pharynx.
Throat problems are common. You've probably had a sore throat. The cause is usually a viral infection, but other causes include allergies, infection with strep bacteria or the leaking of stomach acids back up into the esophagus, called GERD.
Other problems that affect the throat include
Tonsillitis - inflammation of the tonsils
Cancer
Croup - inflammation, usually in small children, which causes a barking cough
Laryngitis - swelling of the voice box, which can cause a hoarse voice or loss of voice
Most throat problems are minor and go away on their own. Treatments, when needed, depend on the problem.
