Swollen Uvula: Symptoms, Causes & What to Do

A swollen uvula, also known as uvulitis, is inflammation of the small piece of tissue that hangs at the back of the throat. It can cause discomfort and is often linked to irritation, infections, or allergic reactions.

A swollen uvula may occur with conditions such as reflux, tonsillitis, mononucleosis, or hereditary angioedema, and is often accompanied by symptoms like sore throat, cough, fever, or a burning sensation. In some cases, it can also cause difficulty swallowing or a feeling that something is stuck in the throat.

Although a swollen uvula is usually mild, it can sometimes signal a more serious problem, especially when breathing or swallowing becomes difficult. Treatment depends on the cause and may include rest, gargling, or medications such as antibiotics, antihistamines, or pain relievers.

Main symptoms

A swollen uvula is usually accompanied by other symptoms, which can vary depending on the cause and may include:

• Sore throat

• A feeling that something is stuck in the throat

• Trouble swallowing or a burning sensation when swallowing

• Hoarseness or voice changes

• Excess saliva production

• Redness and visible swelling of the uvula

In more serious cases, a swollen uvula can cause trouble breathing, swelling of the tongue, lips, face, or throat, and bluish or purplish lips, which may be a sign that the airways are becoming blocked.

Is a swollen uvula dangerous?

A swollen uvula is not always dangerous, and in most cases it is caused by mild infections, allergies, or irritation.

However, if the swelling happens with trouble breathing, swallowing, or speaking, or with swelling of the face, lips, or tongue, it may be an emergency and immediate medical care is needed.

Why is my uvula swollen?

The main causes of a swollen uvula are:

1. Gastroesophageal reflux

Gastroesophageal reflux disease (GERD) happens when stomach contents flow back into the esophagus and cause irritation. Symptoms can include a swollen uvula, a burning sensation in the throat, heartburn, a lump-in-the-throat feeling, and a bitter taste in the mouth.

What to do: See your primary care provider or a gastroenterologist. They may recommend simple measures such as eating a healthy diet, limiting alcohol and high-fat foods, and avoiding smoking.

In addition, a provider may prescribe medications such as metoclopramide to help the stomach empty faster, as well as omeprazole or esomeprazole to reduce the amount of acid in the stomach.

2. Mononucleosis

Mononucleosis, also known as the “kissing disease,” is an infection caused by the Epstein-Barr virus that can lead to symptoms such as a swollen uvula, high fever, throat pain and inflammation, and whitish patches in the throat.

What to do: It is recommended to see a primary care provider, infectious disease specialist, or pediatrician for confirmation. Treatment may include rest, drinking plenty of fluids, and using anti-inflammatory medicine such as ibuprofen, as well as pain relievers such as acetaminophen.

3. Strep throat

Streptococcal pharyngitis (strep throat) is a throat infection caused by Streptococcus bacteria that can lead to a swollen uvula, sore throat, white patches at the back of the mouth, difficulty swallowing, and fever.

What to do: Treatment should be guided by a primary care provider. According to the CDC, strep throat should be treated with antibiotics, typically penicillin or amoxicillin. Other medications, such as anti-inflammatory drugs and pain relievers, may also be prescribed to reduce throat inflammation, relieve pain, and lower fever.

It is also important to choose soft or liquid foods, such as oatmeal, soups, natural juices, and purees, as these can help reduce throat pain and discomfort.

4. Hereditary angioedema

In rare cases, a swollen uvula can be caused by hereditary angioedema, a genetic condition in which fluid leaks out of blood vessels and leads to sudden swelling of the face, hands, feet, or airways.

What to do: An immunologist, allergist, or primary care provider should be consulted to help manage the condition and prevent future attacks, with medications such as icatibant, danazol, oxandrolone, or tranexamic acid (TXA).

If an attack causes swelling in the throat, the person should be taken to the emergency room immediately, because the swelling can block airflow and make breathing difficult.

5. Tonsillitis

Bacterial or viral tonsillitis is an infectious condition that causes inflammation of the tonsils, which can also affect the uvula and lead to symptoms such as a sore throat, swollen uvula, difficulty swallowing, and fever.

What to do: It is important to see your primary care provider or an ENT for evaluation. Treatment depends on whether the infection is viral or bacterial and usually includes rest, staying hydrated, and medications such as antibiotics or anti-inflammatory drugs to relieve pain and reduce fever.

Some home remedies, such as gargling with warm salt water, may also help ease symptoms.

6. Allergies

Allergies to medications, pollen, or certain foods can cause fluid to build up in the throat, which may lead to a swollen uvula as well as symptoms such as itching, skin redness, sneezing, cough, and headache.

What to do: Consultan allergist or your primary care provider, who may recommend medicines such as antihistamines, decongestants, or corticosteroids.

In the case of a severe allergic reaction, called anaphylaxis, immediate medical care is required in the emergency department. According to the CDC, symptoms of anaphylaxis include trouble breathing, a feeling that the throat is closing, or swelling of the mouth, tongue, or face.

7. Smoking

Smoking can cause a swollen uvula because the substances in tobacco can irritate throat tissues, including the uvula, and trigger inflammation.

What to do: Stopping smoking is recommended, and a doctor may prescribe medicines such as varenicline or bupropion to help reduce nicotine cravings and ease withdrawal symptoms like anxiety, irritability, and weight gain.

8. Roseola infantum

A swollen uvula may be caused by roseola infantum, an infectious illness that can lead to symptoms such as high fever, cough, irritation, and sore throat.

What to do: Treatment should be guided by a pediatrician and focuses on controlling symptoms. Medicines such as acetaminophen may be recommended to reduce fever and help prevent febrile seizures.

9. Trauma or localized irritation

A swollen uvula can also result from trauma or direct irritation to the throat, such as burns from very hot foods or drinks, or injuries from medical procedures like endoscopy or intubation.

What to do: In most cases, a swollen uvula gets better on its own. However, it is recommended to drink cold fluids, avoid hot or irritating foods, and see a healthcare provider if there is severe pain, fever, or trouble swallowing.

When to see a doctor

See a healthcare provider if a swollen uvula does not improve after a few days, or if it occurs with symptoms such as fever, increasing pain, warmth or redness, or pus in the area.

Seek emergency medical care right away for any trouble breathing, swelling of the tongue, lips, face, or throat, or blue or purple skin or lips, so treatment can start as quickly as possible.
