Laryngitis is the inflammation of the voice box (larynx). If caused by a virus or bacteria, laryngitis may be contagious. Generally, laryngitis isn’t a severe condition and should resolve in barely three weeks with proper treatment, but in some cases, laryngitis lasts longer and develops into a chronic stage. The larynx is a voice box that has control over our voice. The vocal cord is located inside the larynx and is covered by the mucus lining. The muscles present inside the larynx are responsible for the movement of vocal cords, which helps you to speak.

How is laryngitis diagnosed?

Usually, patients with chronic laryngitis need to seek medical assistance. Hence, the physician is likely to do the following tests:

  • Take a throat swab to identify the cause of laryngitis
  • Pass an endoscope (a narrow lighted tube attached to a camera) that helps the physician to get a closer look at the vocal cord
  • Take a sample of tissue for examination (biopsy) if the physician suspects of a lump or nodule
  • Take an X-ray or skin allergy test to rule out other issues

What is the treatment for laryngitis?

More than any other treatment, voice rest is an ultimate option to treat laryngitis. Medications that may be prescribed for treating the symptoms of laryngitis involve:

  • Antibiotics
  • Steroids
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Anti-reflux medications
  • Mucolytics (medicines that may reduce the viscosity of the mucus)

A speech therapist may teach how to take care of the voice and how to prevent straining of voice.

Numerous home remedies may aid healing, which include:

  • Drink ample amounts of lukewarm water. Better hydration may help in resolving laryngitis.
  • Gargle with warm saltwater because salinity soothes the area and alleviates swelling.
  • Sucking a throat lozenge inclusive of eucalyptus and mint can soothe sore throats.
  • Steam inhalation with menthol may relieve the pain and soreness.
  • Avoid dry, smoky, or dusty rooms
  • Avoid whispering to prevent straining
  • Stay away from decongestants because it may dry out the throat.
  • Avoid coffee or tea
  • Refrain from cigarette smoking
