Swollen Tongue Symptoms

Did that presentation you just gave sound a little funny as you said it? Why does it seem harder to eat? One thing is for sure, something in your mouth just does not feel right. A swollen tongue can be uncomfortable and make it hard to do all the things our mouths do best.

The tongue plays a big role in our daily lives. The tongue lets us taste, assists the mouth with chewing and swallowing, and we do not say that words "roll off our tongue" for nothing. A lot is impacted by a swollen tongue.

Check to see if you have the following swollen tongue symptoms:

  • Difficulty talking, eating, or swallowing
  • Extremely red tongue or pale tongue
  • Tongue lesions and/or bumps
  • Tongue pain and/or mouth soreness
  • Bleeding
  • Fever
  • Swelling
  • Smoothness

The tongue is an organ made up of eight muscles and is covered with a mucous membrane. The upper surface of the tongue is covered in taste buds which detect sweet, bitter, salty, sour, spicy, and savory.

Symptoms of a swollen tongue may present themselves on their own or along with other issues in the body. Carefully considering all the symptoms surrounding a swollen tongue will help determine a cause and treatment.

Swollen Tongue Causes Overview

The causes of a swollen tongue are as varied as the symptoms. What we put in our mouths can often be the driving force behind a swollen tongue, but there are also other, and more serious, reasons for the swelling.

Environmental swollen tongue causes:

  • Trauma: Burning, biting, piercing, or otherwise injuring the tongue.
  • Irritation: Substances such as tobacco, alcohol, and spicy foods can irritate the tongue and cause swelling. Conditions like acid reflux can do the same.
  • Allergies: Reactions to food, medications, bee stings and other oral products can all cause swollen tongue symptoms.
  • Vitamin Imbalance: The lack of proper nutrients in your body, particularly vitamin B complex, vitamin C, and folate, can lead to a swollen tongue.

Inflammatory swollen tongue causes:

  • Infections: Bacterial infections of the tongue or other parts of the body can result in tongue swelling. Strep, syphilis, herpes, and yeast infections have all been known to cause a swollen tongue.

Systemic disease swollen tongue causes:

  • Cancer: Tongue cancer causes swelling as it spreads. Typically, cancer starts on one part of the tongue and swelling may be minimal, but persistent tongue swelling is typical with tongue cancer.
  • Metabolic: Disruptions to metabolic functions can cause tongue swelling. Pituitary gland disorders are an example of metabolic disorders.
  • Hereditary: Inherited disorders, such as Down syndrome, can affect many aspects of the body, including the tongue.

Top 4 Swollen Tongue Causes

  1. 1.Swelling Caused by Use of an Ace Inhibitor

    ACE Inhibitors are drugs used to prevent, treat or improve symptoms in conditions such as high blood pressure, coronary artery disease, heart failure and diabetes. In rare cases, these drugs can cause an allergic reaction that can be life-threatening.

    You should go to the ER immediately. There, your doctor can consider the possibility of an allergic reaction, treat it, and make sure that you are able to breathe.

    Top Symptoms:
    shortness of breath, swollen face, trouble swallowing, swollen lips, swollen tongue
    Symptoms that never occur with swelling caused by use of an ace inhibitor:
    hives, red swollen bumps or patches with a pale center
    Hospital emergency room
  2. 2.Hypothyroidism

    Hypothyroidism occurs when the thyroid, a butterfly-shaped organ inside the neck, no longer produces adequate levels of hormones. Thyroid hormones are essential for many bodily functions including breathing, heart rate, and metabolism.

    You should visit your primary care physician. Hypothyroidism is a complex condition that is usually treated with hormone replacement therapy.

    Top Symptoms:
    fatigue, depressed mood, difficulty concentrating, weight gain, muscle aches

Swollen Tongue Treatments and Relief

We have all sipped before we should have and burned our tongue, maybe even caused it to swell. Unfortunately, we also all know that the treatment typically involves simply waiting for the pain to subside. When a swollen tongue is more persistent, however, or there are other swollen tongue symptoms present, advanced treatment may be required.

Contacting your doctor is recommended when you experience the following swollen tongue symptoms:

  • Persistent swelling of over 10 days.
  • Extreme swelling
  • Problems breathing, swallowing, chewing, and speaking
  • Swelling associated with an allergic reaction
  • Swelling associated with an infection

It is recommended to contact emergency personnel if tongue swelling is preventing breathing or a blocked airway is imminent.

Often times, managing a swollen tongue can be done by taking steps to treat the underlying cause. There are several treatment alternatives that could be attempted without consulting a medical professional. More advanced issues with a swollen tongue will require more aggressive measures.

At-home swollen tongue treatments:

  • Lifestyle: Changes in diet can help reduce swelling caused by a variety of factors. Eliminating sour or spicy foods and tobacco can sometimes cure a swollen tongue. Minimizing chewing or instituting a liquid diet may also help.
  • Over-the-Counter Medications: NSAIDs, such as ibuprofen, can help reduce inflammation.

Professional swollen tongue treatments:

  • Prescription Medications: Advanced cases of tongue swelling may require medications prescribed by a doctor.
  • Advanced medical procedures: Surgery, radiation therapy, and/or chemotherapy may be required to treat tongue cancer.

A swollen tongue can make it difficult to chew and talk, but, often times, is not a cause for serious concern. There is always the potential for a more significant cause, however, so it is important to monitor symptoms and ensure proper treatment for a swollen tongue.
