Glossitis: Causes, Symptoms, Diagnosis, Treatment, and Prevention

Glossitis occurs when the tongue becomes inflamed, swollen, and changes in color and texture due to inflammation. It can cause different symptoms and affect how one speaks, eats, or swallows, and can have different types and causes. The purpose of this blog post is to explain glossitis, what its symptoms and causes are, how it is treated, and how it can be prevented.

What is glossitis?

There are many small bumps on the tongue called papillae, which contain taste buds and allow us to sense different flavors. Glossitis means inflammation of the tongue. The tongue is a muscular organ that helps us taste, chew, and swallow food. Furthermore, the tongue has a protective mucous membrane that keeps it moist and prevents infections.

When the tongue becomes inflamed, it can swell up and change in color and texture. The papillae may shrink or disappear, making the tongue look smooth and glossy. Glossitis can also cause the tongue to become red, pale, or patchy. Glossitis may affect the tongue in its entirety or only parts of it.

Inflammation of the tongue can be acute or chronic, depending on how long it persists and how often it recurs. Acute glossitis usually develops suddenly and is characterized by severe symptoms. Chronic glossitis is characterized by persistent or recurrent inflammation of the tongue.

What are the symptoms of glossitis?

The symptoms of glossitis vary from person to person, depending on the type and cause of the condition. Some common symptoms of glossitis include:

• A swollen tongue

• Pain or tenderness in the tongue

• Burning or itching sensation in the tongue

• Change in the color and texture of the tongue

• Difficulty speaking, eating, or swallowing

• Altered taste or loss of taste

Some types of glossitis may have specific symptoms, such as:

• In atrophic glossitis, the papillae shrink or disappear, making the tongue appear smooth and glossy. People with atrophic glossitis may also experience a sore mouth or burning sensation in the tongue, as well as paleness or redness of the tongue. Nutritional deficiencies, such as vitamin B12 and iron deficiency, are often associated with the condition.

• In this type of glossitis, a red, smooth, flat, or raised area appears on the middle or back of the tongue. Fungal infections, such as candida, are often responsible for medial rhomboid glossitis, which may also affect the palate and cheeks. There may be a white coating on the tongue or other areas, as well as burning or metallic tastes in the mouth.

• Patches of missing papillae and smooth, red lesions on the tongue are symptoms of geographic tongue. Eventually, the patches may move from one area to another of the tongue, changing in size, shape, and location. It is a harmless condition that does not cause pain or discomfort, but it can affect the taste sensation or make the tongue more sensitive to spicy or acidic foods.

• Symptoms of burning tongue syndrome include burning, tingling, or numbness on the tongue tip and roof of the mouth. In addition to affecting people of all ages, burning tongue syndrome is more common in women after menopause. There is no definitive cause for burning tongue syndrome, but it may be caused by hormonal changes, dry mouth, stress, anxiety, or depression.

What are the causes of glossitis?

There are many possible causes of glossitis, such as:

• Glossitis can be caused by allergic reactions to certain foods, medications, and dental products. In addition to swelling, redness, and itching of the tongue, other symptoms of an allergic reaction may include hives, rash, itching, swelling, or difficulty breathing. An allergic reaction can be a medical emergency, so the patient should seek immediate medical attention.

• It is possible to contract glossitis from bacteria, viruses, or fungal infections, particularly when they affect the mouth or tongue. Infections that can cause glossitis include oral herpes, which causes blisters or sores on the tongue or lips; strep throat, which causes fever and a sore throat; and candida, which causes a white coating on the tongue or lips. As well as pain, fever, chills, and malaise, other symptoms of infection may be present.

• In particular, nutritional deficiencies can cause glossitis if they affect the health of the tongue and mouth. Some common nutritional deficiencies that can cause glossitis include vitamin B12 deficiency, which can cause pernicious anemia and nerve damage; iron deficiency, which can cause anemia and weakness; and folate deficiency, which can cause anemia and birth defects. Symptoms of nutritional deficiencies may also include fatigue, pale skin, shortness of breath, or tingling in the hands or feet.

• An injury to the mouth, such as a cut, burn, bite, or scrape, can result in glossitis, especially if the tongue is damaged. Inflammation, swelling, or infection of the tongue may result in pain or difficulty speaking or eating. Until the injury has healed, the person should keep their mouth clean and avoid irritating foods and drinks.

• There is a condition called dry mouth, or xerostomia, in which saliva is not produced enough to keep the mouth moist and free from infections. As well as glossitis, dry mouth can cause bad breath, tooth decay, gum disease, or mouth sores. There are many causes of dry mouth, including dehydration, medication, aging, smoking, and diseases including diabetes, Sjögren's syndrome, and HIV/AIDS. Drinking plenty of water, chewing sugar-free gum, or using artificial saliva products can relieve dry mouth.

• In addition to irritating the tongue and mouth, tobacco and alcohol consumption can cause oral cancer, leukoplakia, and oral thrush, as well as other oral health problems. In addition to causing glossitis, tobacco and alcohol use can interfere with nutrient absorption, such as vitamin B12 or iron. If needed, a healthcare provider can assist the individual in quitting or reducing tobacco and alcohol usage.

• A change in hormones, such as those during pregnancy, menstruation, or menopause, can affect the tongue and mouth, causing glossitis. Infections or allergic reactions can be caused by hormonal changes, which can also affect the immune system. It is important that the person maintains good oral hygiene, eats a balanced diet, and consults with a healthcare provider if the symptoms persist or become severe.

How is glossitis diagnosed?

To diagnose glossitis, a healthcare provider will examine the tongue and the mouth, and ask about the symptoms, medical history, and possible causes of glossitis. The healthcare provider may also perform some tests, such as:

• Blood tests: Blood tests can help detect any nutritional deficiencies, infections, or diseases that can cause glossitis, such as vitamin B12 or iron deficiency, anemia, diabetes, or HIV/AIDS.

• Swab tests: Swab tests can help identify any bacterial, viral, or fungal infections that can cause glossitis, such as strep throat, oral herpes, or candida.

• Biopsy: Biopsy is a procedure in which a small sample of tissue is taken from the tongue and examined under a microscope. Biopsy can help rule out any serious conditions that can cause glossitis, such as oral cancer or leukoplakia.

How is glossitis treated?

The treatment of glossitis depends on the type and cause of the condition. Some common treatments for glossitis include:

• Medications: Medication can be used to treat any infections, allergies, or diseases that can cause glossitis, such as antibiotics for bacterial infections, antivirals for viral infections, antifungals for fungal infections, antihistamines for allergies, or steroids for inflammation. Follow the healthcare provider's instructions and take the prescribed medication as prescribed.

• Supplements: Supplements can help correct nutritional deficiencies that can cause glossitis, such as vitamin B12 or iron for anemia, or folate supplements for pregnant women. A healthcare provider must be consulted before taking supplements and follow the dosage and duration recommended.

• Changes in lifestyle can reduce or prevent glossitis, such as quitting or reducing tobacco and alcohol use, drinking plenty of water, avoiding spicy or acidic foods, or using a humidifier. It is also important for the individual to practice good oral hygiene, which includes brushing and flossing their teeth regularly, using a soft toothbrush, and rinsing with salt or baking soda.

• Glossitis rarely requires surgery unless the swelling is severe and blocks the airway or a suspicious lesion needs to be removed. A person should discuss the risks and benefits of surgery with their healthcare provider, and follow the post-operative instructions. Surgery can reduce the tongue size, remove the lesion, or improve tongue function.

How can glossitis be prevented?

Some tips to prevent or reduce the risk of glossitis are:

• Eat a balanced diet that includes foods rich in vitamin B12, iron, and folate, such as meat, eggs, dairy, beans, leafy greens, and fortified cereals.

• Avoid foods or drinks that may irritate the tongue, such as spicy, acidic, or hot foods, alcohol, or tobacco.

• Drink plenty of water to keep the mouth hydrated and prevent dry mouth.

• Brush and floss the teeth regularly, and use a soft toothbrush and a mild toothpaste.

• Rinse the mouth with salt water or baking soda solution to soothe the tongue and prevent infections.

• Visit the dentist regularly for check-ups and cleaning, and report any signs of glossitis or other oral problems.

• Avoid or limit the use of medications that may cause dry mouth or tongue inflammation, such as antihistamines, diuretics, or antidepressants. Consult the doctor before stopping or changing any medication.

• Manage any underlying conditions that may cause glossitis, such as diabetes, anemia, or Sjögren’s syndrome. Follow the treatment plan and monitor the blood sugar, hemoglobin, or saliva levels as advised by the doctor.

• Seek medical attention if glossitis symptoms are severe, persistent, or recurrent, or if they interfere with breathing, speaking, eating, or swallowing.
