What Causes Acid Reflux/GERD?

What causes Acid Reflux

Acid reflux is a common symptom for many chronic diseases like GERD. It happens to everyone at some point in life. Nowadays one in five people are suffering from acid reflux and is more common in Western countries. The main symptom of acid reflux is the burning sensation in the stomach, which is also known as heartburn. First, let’s learn what heartburn/GERD is, and then move on to acid reflux. So that it will be easy for you to understand the differences between them. 

What is Heartburn? 

Heartburn is nothing but a burning pain or irritation, which usually happens in the lower chest area. It is caused due to the backup of stomach acid into the food pipe, i.e, the esophagus. It is quite normal and lasts from a few minutes to hours. But chronic heartburn leads to deadly diseases.

What is GERD? 

The full form of GERD is Gastroesophageal reflux disease. GERD is diagnosed when acid reflux occurs continuously for more than two weeks. In short, chronic acid reflux is the first and main symptom of GERD. 

The American College of Gastroenterology says that approximately 60 million Americans experience heartburn or acid reflux at least once a month, and more than 15 million people often suffer from acid reflux daily.

Now we’ll come to acid reflux. What is acid reflux? 

Normally, the food we eat is chewed thoroughly in the mouth and reaches the stomach through the food pipe, which is also called the esophagus. 

At the entrance of your stomach, there is a valve called the Lower esophageal sphincter (LES). The main function of this valve is to open and close as soon as the food passes through it. That is, the valve opens for the food to enter into the stomach and immediately shuts down to prevent the food from flowing back. 

In the stomach, it produces a strong hydrochloric acid that helps in the digestion process. This strong acid is called stomach acid and is responsible for faster digestion. It also kills the pathogens in the stomach. The inner lining of the stomach is adapted to the stomach acid but the esophagus does not. 

So if the LES is not closed properly, the acid produced by your stomach might move up into the esophagus and create a  burning sensation or discomfort in the chest area and the abdomen. This burning feeling is called heartburn. 

If heartburn happens more than twice a week, then it is called acid reflux disease or acid regurgitation, or gastroesophageal reflux. If it continues even more then it is called chronic acid reflux, also known as gastroesophageal reflux disease (GERD). Here the stomach acid persistently flows back up to your mouth giving a sour taste. This leads to various other symptoms. 

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), about 20 percent of people are affected by GERD in the United States. If left untreated, it can sometimes cause serious complications.

What Causes Acid Reflux Disease?

A common cause for acid reflux disease is the abnormality of the stomach called a Hiatal hernia. This occurs when the upper part of the abdomen and the lower esophageal valve move above the diaphragm. The diaphragm is a muscle that separates your abdomen from your chest. 

In general, the diaphragm helps keep acid in our stomach. But if you have a hiatal hernia, then the acid can go up to your esophagus and cause symptoms of acid reflux disease. There are some common risk factors that cause acid reflux disease. They include;

1. Certain foods and drinks

Many people usually get acid reflux after eating certain foods. For example, foods that are high in fats, acid, spicy foods, carbonated drinks, etc are the risk factors. Those foods may be difficult to digest and so the stomach produces extra acid for digestion, which can end up in the esophagus causing acid reflux. Such foods include:

Chocolate: High in fat, cocoa, and caffeine that causes reflux.

Soda/Carbonated drinks: Highly acidic

Fried Foods: Deep-fried foods have high-fat content, which leads to reflux.

Alcohol: Beer, wine, and liquor are highly acidic

Dairy products: High-fat butter and cheese may also be a cause.

Coffee: High is caffeine. Instead of coffee, you can switch to green tea or herbal teas. 

High-fat meats, onions, garlic, mint, tomatoes, oranges, etc are also some other foods that cause acid reflux. 

2. Obesity 

Excess fat in the abdomen adds pressure to the stomach, which pushes up acid into the esophagus. Hormones can also play a role in acid reflux. People who are obese have high estrogen, which is associated with GERD symptoms. 

3. Hiatal Hernia 

A hiatal hernia is a disease caused when the upper part of your stomach swells up into your chest cavity, blocking the LES from closing properly.

In many people, Hiatal hernias do not show any symptoms, while in others it is a symptom of GERD. It is more common above the age of 50.

4. Eating a Large Meal

Eating a heavy meal at any time can trigger acid reflux, but it is very troublesome if you do it before going to bed. Lying down when the stomach is full is an easy way to push the acid back into the esophagus. 

5. Smoking

Smoking can damage your digestive system as well as many other parts of your body. Smoking and chewing tobacco can lead to reflux by relaxing the LES.

6. Pregnancy

Almost all pregnant women experience acid reflux. It can start at any point during their pregnancy. The uterus enlarges and increases the pressure in the abdomen. Hormones will be higher, which tends to relax the sphincter muscle causing reflux. 

7. Medications

Though medications relieve us from various ailments, they all have side effects. And sometimes the side effect may be acid reflux. Medications that make reflux worse include:

  • Pain relievers like ibuprofen and aspirin
  • Antihistamines for allergies
  • Blood pressure drugs
  • Sedatives
  • Tricyclic antidepressants
  • Oral osteoporosis drugs
  • Anticholinergic drugs
  • Certain antibiotics, including tetracycline
  • Opioids
  • Iron and potassium supplements 

So consult your doctor if any of your medications can contribute to reflux. So they can suggest an alternative without having any side effects.

8. Stress

Almost everyone will have experienced stress at least once in their lifetime. Experts have theorized that anxious people may produce more stomach acid during the time of stress. Therefore, stress can also trigger acid reflux.

9. Scleroderma

Scleroderma is an autoimmune disease that attacks the connective tissue of the body. Many people complain of acid reflux as a symptom of Scleroderma. Tissue scarring with scleroderma causes food to move very slowly through your digestive tract, which in turn prevents the LES from closing properly.
