Swollen Uvula (Throat)

Uvulitis is the medical term for an inflamed uvula. The process of inflammation causes swelling of the uvula and this may also be accompanied by pain and redness. Since the uvula is a suspended organ, inflammation will cause it to hang down more than usual or even touch the tongue apart from its horizontal  expansion.

The uvula may swell for a number of reasons and this is usually associated with inflammation of the neighboring mouth and throat structures.

Presentation of a Swollen Uvula

At times it is difficult to identify a swollen uvula from a normal uvula just based on its size and length. Anatomical variations may mean that the uvula is naturally long or big in some people. When elongated due to swelling, the uvula may appear to touch the tongue, however it is important to take note if the uvula is swollen or if it is the tongue that is inflamed (glossitis). In obese or overweight patients, the tongue may be raised upwards making the distance between the tongue and palate much smaller. In this case, the structures at the back of the throat, like the uvula,  may not be clearly visible.

Other signs and symptoms may help with identifying an enlarged uvula due to swelling and these include :

  • Redness of the uvula.
  • Pain which aggravates when the uvula is touched or during swallowing.
  • Sensation of a foreign body at the back of the mouth or throat.
  • Changes in the voice quality¬† from the normal tone.
  • Gagging.

In a case where the uvula become swollen due to edema without an infection or inflammation, then the uvula may appear enlarged and pale. This uvula edema is known as uvular hydrops or Quincke’s edema and typically occurs due to non-infectious causes like an allergy.

Causes of a Swollen Uvula

When identifying the cause of a swollen uvula, it is important to take note of other concomitant signs and symptoms. This will assist with a correct diagnosis as a swollen uvula is usually a symptom of an underlying condition rather than being a disorder on its own. Some causes of a swollen uvula include :

  • Infection. Throat infections like a strep throat will cause inflammation of the uvula along with surrounding throat structures like the the tonsils (tonsillitis) and pharynx (pharyngitis).
  • Allergy. Angioedema causes the uvula to swell (Quincke’s disease) and other signs and symptoms of an allergic reaction will also be evident, like swelling of the cheek, upper lip, around the eye, itchy throat, skin or eyes and/or an itchy skin rash.
  • Chemical trauma. Certain ingested substances, either food or drink, can cause irritation of the mouth and throat structures including the uvula. This includes acidic, spicy and hot substances or other known irritants. like alcohol. Mouth washes made of herbs and other chemicals that may cause irritation of the lining of the mouth and throat and may result in uvulitis.
  • Physical trauma to the mouth or throat by the deep insertion of large foreign bodies into the mouth – example endoscope or after intubation.
  • Gastroesophageal reflux disease (GERD). In severe cases, the rising gastric acid pools in the back of the throat, especially during sleep, and can inflame the structures at the back of the throat.
  • Nasal congestion or any other cause of mouth breathing will cause edema of the uvula where it will appear pale, yet swollen.
  • Dehydration may also cause a pale swelling of the uvula.
  • Snoring.
  • Uvula piercing.
  • Vomiting.
  • Mouth sores that may affect the uvula.
  • Post nasal drip.
  • Persistent coughing.
  • Peritonsillar abscess.
  • Cigarette smoking.
  • Narcotic use – smoking or ‘snorting’ narcotic drugs.
  • Prescription drugs.

The uvula tends to hang downwards (vertically) but may deviate laterally (to the side). The deviation of the uvula, along with swelling, may be a strong indication of a peritonsillar abscess or parapharyngeal abscess. A deviated uvula with no evident swelling may be due to a lesion of the vagus nerve, which is the cranial nerve that innervates the uvula.

    My age is 50 years . when I was around 23 , I start suffering from semi continous tonsilitis and pharyngitis,I got tonsilectomy when I was 26 , But I continued to suffer from recurrent pharyngitis untill 40 yeas old,after that I stopped suffering from pharyngitis but my uvula began to inflame and congest till now .

    Note: I have mild postnasal drip ,
    X-rays to sinuses is always clear and no signs of inflammation.
    the inflammation is mild to middle ( not severe) during all the stages ( tonsilitis to pharyngitis to uvulitis) .
    So what is the diagnosis? please

    Abdussalam,

    As you would have read on the terms of this comment service, we do not provide a diagnosis. We are here just to guide readers with seeking appropriate medical care. Considering that this condition is chronic, you should see an ENT specialist (ear-nose-throat or otolaryngologist). Further tests and so on will be necessary. Apart from post nasal drip, if you are a smoker then you need to stop smoking before considering treatment. GERD (acid reflux) may be another possible cause that needs to be dealt with as the acid can rise as high as the throat and cause persistent irritation. Refer to Chronic sore throat.

    ok so i have a swollen uvula and tonsils, my tongue is also swollen with red bumps in the back in the shape of a “v”. I have the worst body aches that i have ever experienced in my life. it is also very VERY hard to breath and it feels lie in going to swallow my uvula.. what is it and what do i do?

    Hi Beckakelly13

    It is difficult to say whether these body aches and shortness of breath is related to the inflamed uvula and tonsils. If it is, it may be due to a viral infection and you need to see your doctor immediately. There are a number of causes as you can see above but the only way to diagnose it is for your doctor to examine you and possibly run further tests if necessary.
