Acid reflux, also known as gastroesophageal reflux disease (GERD), is a common condition where stomach acid flows back up into the esophagus. This can cause a variety of symptoms, including heartburn, regurgitation, chest pain, difficulty swallowing, and in some cases, an orange tongue.
What Causes Acid Reflux?
Acid reflux occurs when the lower esophageal sphincter (LES), a ring of muscle that separates the esophagus from the stomach, relaxes or weakens. Normally, the LES closes after food passes through to the stomach to prevent backflow. However, if the LES malfunctions, acidic stomach contents can rise up into the esophagus.
Some common causes and risk factors for acid reflux include:
- Hiatal hernia – when part of the stomach protrudes through the diaphragm into the chest
- Pregnancy – hormones cause the LES to relax
- Obesity
- Smoking
- Certain medications like anticholinergics
- Eating large meals
- Eating late at night
- Consuming spicy, acidic, or fatty foods
- Drinking alcohol
- Lying down soon after eating
What Is an Orange Tongue?
An orange tongue refers to a discoloration where the tongue takes on an abnormal orange hue. The top surface of the tongue is normally pink, so an orange tongue is indicative of a problem.
There are several potential causes for an orange tongue:
- Acid reflux – Stomach acid can irritate and inflame the tongue, leading to an orange coating.
- Oral thrush – A fungal infection that causes cottage cheese-like white patches on the tongue and mouth that can look orange.
- Dehydration – A lack of fluids can make the tongue appear more orange and dry.
- Poor oral hygiene – Not properly brushing and cleaning the tongue allows bacteria buildup, resulting in discoloration.
- Food stains – Eating certain foods like carrots, oranges, or tomato sauce can temporarily stain the tongue orange.
- Leukoplakia – White patches on the tongue that can develop into oral cancer.
- Lichen planus – An inflammatory condition that produces lace-like white patterns on the tongue.
Can Acid Reflux Cause an Orange Tongue?
Yes, acid reflux can sometimes cause an orange discoloration on the tongue. When stomach acid backs up into the esophagus, it can also reach the back of the tongue. The acid can irritate the taste buds and lining of the tongue, leading to inflammation that turns the surface orange.
Research has shown a link between acid reflux and tongue discoloration or soreness. One study found that 18% of people with acid reflux had an associated tongue disorder. The acidic environment from stomach juices can erode the tongue tissue, causing sensitivity, pain, and orange coloring.
The more severe and frequent the acid reflux episodes, the more likely the acid is to affect the tongue. People with chronic reflux struggle with persistent acid irritation of the esophagus and throat area. This constant exposure means the tongue is more prone to damage.
Symptoms of Acid Reflux-Related Orange Tongue
Along with an orange discoloration of the tongue, symptoms of acid erosion on the tongue include:
- A sore, sensitive tongue
- A burning sensation on the tongue
- Loss of taste or metallic taste in the mouth
- Tongue pain or tenderness
- Canker sores on the tongue
- A rough, almost sandpaper-like feeling of the tongue
These symptoms occur as a result of inflammation and irritation from stomach acid washing over the tongue. The high acidity damages and inflames the taste buds and tongue tissue. Other accompanying symptoms of acid reflux itself may be present like heartburn, hoarseness, regurgitation, asthma, and trouble swallowing.
Is There a Connection Between Acid Reflux and Glossitis?
Yes, glossitis, which is inflammation of the tongue, has been linked to acid reflux. When gastric acid repeatedly comes in contact with the back of the tongue, it can cause glossitis.
In one study, 67% of people with acid reflux were found to have glossitis compared to only 7% of healthy controls. The high acid environment appears to trigger inflammation of the tongue’s surface.
Glossitis related to acid damage may specifically manifest as papillary atrophy. The filiform papillae, which are small bumps on the tongue, can erode from excess stomach acid. This erosion flattens the tongue and removes the papillae, resulting in a smooth, sore, and glossy appearance.
Signs of Glossitis
- Red or pink tongue
- Swollen tongue
- Smooth tongue surface
- Pain or burning feeling
- Increased sensitivity
- Poor taste
- Glossy appearance
Treating the underlying acid reflux will help resolve inflammation and irritation associated with glossitis.
Treatments for Acid Reflux-Related Orange Tongue
An orange tongue caused by acid reflux will usually resolve with treatment of the reflux itself. By preventing acid from reaching the tongue, the irritation and discoloration can clear up.
1. Medications
There are several categories of medications that help reduce reflux and acid production:
- Antacids – Help neutralize stomach acid temporarily but do not prevent reflux.
- H2 blockers – Reduce acid production like famotidine (Pepcid) or ranitidine (Zantac).
- Proton pump inhibitors – More potent acid suppression from omeprazole (Prilosec), esomeprazole (Nexium).
- Prokinetics – Help strengthen the LES and speed up digestion like metoclopramide (Reglan).
2. Home Remedies
- Avoid trigger foods like coffee, alcohol, chocolate, spicy foods.
- Don’t eat 2-3 hours before bed.
- Quit smoking and lose weight if overweight.
- Raise the head of your bed 6-8 inches.
- Avoid tight clothing.
3. Surgery
For severe, uncontrolled cases, surgery can reconstruct or augment the lower esophageal sphincter. Procedures like laparoscopic fundoplication can prevent reflux from occurring in the first place.
When to See a Doctor
You should consult a doctor or gastroenterologist if you experience:
- Frequent or severe acid reflux
- An orange tongue that doesn’t resolve with over-the-counter medication
- Difficulty or pain swallowing
- Unintentional weight loss
- Blood in vomit or stools
A persistent orange tongue along with other concerning symptoms may require further evaluation to rule out any complications of reflux or other underlying conditions.
Diagnosing Acid Reflux Related Orange Tongue
To confirm acid reflux as the cause of an orange tongue, a doctor may perform the following diagnostic tests:
- Endoscopy – A tiny camera on a flexible tube is inserted into the throat to visually inspect for damage.
- Biopsy – Taking a small sample of tissue from the tongue to check for glossitis or oral thrush.
- pH monitoring – A probe measures acid levels in the esophagus to confirm reflux.
- Manometry – Measures pressure and muscle contractions in the esophagus.
Blood tests can help rule out any nutritional deficiencies like iron, folate, or vitamin B12 which can sometimes cause tongue inflammation. Your doctor will also review your medications to check for side effects.
Prevention Tips
You can help prevent acid reflux-related tongue irritation using these tips:
- Eat smaller, more frequent meals
- Avoid food triggers like fatty, spicy food
- Don’t lie down after eating
- Limit alcohol and caffeine
- Quit smoking, lose weight if overweight
- Take antacids or acid reducers if needed
- Practice good oral hygiene by brushing your teeth and tongue
When to Seek Emergency Care
In rare cases, severe acid reflux complications may require emergency care. Seek medical help immediately if you experience:
- Vomiting blood or passing bloody stool
- Severe chest pain that radiates to the arm, neck or back
- Choking sensation or intense difficulty swallowing
- Shortness of breath or wheezing
These symptoms can indicate a serious issue like an ulcer, esophageal stricture, or aspiration and require prompt evaluation in an emergency setting.
Conclusion
In summary, acid reflux can sometimes cause an orange discolored tongue. Stomach acid washing over the tongue can lead to irritation, inflammation, and tissue damage resulting in an abnormal orange hue.
Treating the underlying reflux with medications, diet and lifestyle changes, or surgery can help resolve acid-related glossitis and orange tongue. Working with your doctor and following prevention methods allows you to better manage reflux and avoid associated tongue complaints.
