Pharyngitis

10 min read

Pharyngitis is an inflammation of the pharynx, the area at the back of the throat. It is usually caused by a viral or bacterial infection, but can also be caused by allergies, irritants, or acid reflux. Pharyngitis can be acute or chronic, and can cause a sore throat, difficulty swallowing, and swollen lymph nodes.

Causes of Pharyngitis

The most common cause of pharyngitis is a viral infection, such as the common cold or flu. Bacterial infections, such as strep throat, can also cause pharyngitis. Other causes include allergies, irritants, and acid reflux.

Diagnosis of Pharyngitis

A doctor will typically diagnose pharyngitis based on a physical examination and a review of the patient's symptoms. In some cases, a throat swab or other tests may be necessary to determine the cause of the infection.

Complications of Pharyngitis

If left untreated, pharyngitis can lead to complications such as sinus infections, ear infections, and pneumonia. It can also cause long-term damage to the throat and vocal cords.

Prevention of Pharyngitis

The best way to prevent pharyngitis is to practice good hygiene, such as washing your hands regularly and avoiding close contact with people who are sick. It is also important to avoid smoking and exposure to secondhand smoke.

Take the Pharyngitis Assessment

Symptoms

  • Sore throat
  • Painful swallowing
  • Hoarseness
  • Swollen lymph nodes in the neck
  • Fever
  • Cough
  • Headache
  • Fatigue
  • Bad breath

If you experience any of these symptoms, it is important to see your doctor for a diagnosis and treatment. Your doctor may recommend antibiotics if the cause of your pharyngitis is bacterial.

Causes

Allergies

Allergies can cause inflammation of the throat, leading to pharyngitis. Allergens such as pollen, dust, and pet dander can cause an allergic reaction that leads to swelling and irritation of the throat. Allergic pharyngitis can also be caused by certain foods, such as dairy products, eggs, and nuts.

Irritants

Exposure to certain irritants can also cause pharyngitis. Cigarette smoke, air pollution, and chemical fumes can all irritate the throat and lead to inflammation. Inhaling these irritants can cause a sore throat, difficulty swallowing, and swollen glands in the neck.

Acid Reflux

Acid reflux is a condition in which stomach acid flows back up into the esophagus, causing irritation and inflammation of the throat. This can lead to pharyngitis, as well as other symptoms such as heartburn and chest pain.

Injury

Injury to the throat can also cause pharyngitis. This can include physical trauma, such as a blow to the throat, or chemical trauma, such as exposure to caustic substances. Injury to the throat can cause swelling and irritation, leading to pharyngitis.

Gastroesophageal Reflux Disease (GERD)

Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid flows back up into the esophagus, causing irritation and inflammation of the throat. This can lead to pharyngitis, as well as other symptoms such as heartburn and chest pain.

Tumors

In rare cases, tumors in the throat can cause pharyngitis. Tumors can cause swelling and irritation of the throat, leading to a sore throat, difficulty swallowing, and swollen glands in the neck.

Getting a Diagnosis

Physical Exam

A physical exam is the first step in diagnosing pharyngitis. During the exam, the doctor will look for signs of infection, such as redness, swelling, and tenderness in the throat. They may also check for swollen lymph nodes in the neck.

Lab Tests

If the physical exam suggests a bacterial infection, the doctor may order a lab test to identify the specific bacteria causing the infection. This can help the doctor determine the best course of treatment.

Imaging Tests

In some cases, the doctor may order imaging tests, such as an X-ray or CT scan, to look for signs of infection in the throat or other areas of the body.

Treatment

Treatment for pharyngitis depends on the cause of the infection. Viral infections usually resolve on their own, but bacterial infections may require antibiotics. In some cases, the doctor may recommend over-the-counter medications to help relieve symptoms.

Questions for Your Doctor

Symptoms

Your doctor will want to know what symptoms you are experiencing. Common symptoms of pharyngitis include sore throat, difficulty swallowing, fever, swollen lymph nodes, and a white or yellow coating on the back of the throat. Be sure to tell your doctor about any other symptoms you may be experiencing.

Prevention

Your doctor may also discuss ways to prevent pharyngitis. Good hygiene is important to help prevent the spread of infection.
