Understanding Acid Reflux: Causes, Symptoms, and Prevention
Acid reflux, also known as gastroesophageal reflux disease (GERD), is a common condition that occurs when stomach acid flows back into the esophagus. This can cause a burning sensation, pain, and other uncomfortable symptoms.
Causes of Acid Reflux
There are a number of factors that can contribute to acid reflux, including:
- Hiatal hernia: This is a condition in which the stomach protrudes through an opening in the diaphragm. This can weaken the lower esophageal sphincter (LES), which is a muscle that helps to keep stomach acid from flowing back into the esophagus.
- Weakened lower esophageal sphincter (LES): The LES is a muscle that acts as a valve between the stomach and esophagus. When the LES is weakened, it can allow stomach acid to flow back into the esophagus.
- Increased abdominal pressure: This can occur due to obesity, pregnancy, or certain medical conditions. Increased abdominal pressure can push stomach acid up into the esophagus.
- Certain foods and beverages: Some foods and beverages, such as fatty foods, spicy foods, and alcohol, can relax the LES and increase the risk of acid reflux.
Symptoms of Acid Reflux
The most common symptom of acid reflux is a burning sensation in the chest, which is often worse after eating or lying down. Other symptoms of acid reflux can include:
- Pain in the chest or abdomen
- Nausea
- Vomiting
- Regurgitation of food or liquid
- Difficulty swallowing
- Hoarseness
- Chronic cough
Complications of Acid Reflux
If left untreated, acid reflux can lead to a number of serious complications, including:
- Esophagitis: This is an inflammation of the esophagus. It can cause pain, bleeding, and scarring.
- Barrett’s esophagus: This is a condition in which the cells in the esophagus change in response to chronic acid reflux. Barrett’s esophagus can increase the risk of esophageal cancer.
- Esophageal cancer: This is a type of cancer that occurs in the esophagus. It is the eighth leading cause of cancer death in the United States.
Preventing Acid Reflux
There are a number of things you can do to help prevent acid reflux, including:
- Eat smaller meals more frequently.
- Avoid eating fatty, spicy, or acidic foods.
- Avoid drinking alcohol.
- Lose weight if you are overweight or obese.
- Elevate the head of your bed by 6-8 inches.
- Avoid lying down after eating.
- Quit smoking.
Treating Acid Reflux
If you experience frequent or severe acid reflux, you should see your doctor. There are a number of medications that can be used to treat acid reflux, including:
- Antacids: These medications neutralize stomach acid.
- H2 blockers: These medications reduce the production of stomach acid.
- Proton pump inhibitors (PPIs): These medications block the production of stomach acid.
In some cases, surgery may be necessary to treat acid reflux. Surgery can be used to tighten the LES or to create a new valve between the stomach and esophagus.
