Throat Disorders

Also called: Pharyngeal disorders

Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for throat is 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 upward movement of stomach acids into the esophagus, called GERD.

Other problems that affect the throat include

  • Tonsillitis - an infection in the tonsils
  • Pharyngitis - inflammation of the pharynx
  • Cancers
  • Croup - inflammation, usually in small children, which causes a barking cough

Most throat problems are minor and go away on their own. Treatments, when needed, depend on the problem.

  • Acute upper airway obstruction
  • Epiglottitis
  • Glossopharyngeal neuralgia
  • Herpangina
  • Laryngitis
  • Laryngoscopy
  • Retropharyngeal abscess
  • Strep throat
  • Throat swab culture
