Myths and truths about gastritis

In popular culture, much is said about gastritis, but there’s only one truth, and, in this article, we’ll tell you what is true and what isn’t.

Myth 1: Gastritis is an infection

This isn’t true. The truth is that this disease can be caused by many factors, but one of the main ones is bacteria, and more specifically, the Helicobacter pylori bacteria. In fact, it causes 90% of cases.

H. pylori bacteria are common in developing countries. It can live in the body without causing symptoms, but it’s also capable of causing the development of ulcers, stomach cancer, and gastritis.

Gastritis is thought of as an infection, when in fact it may be the consequence of an infection. An infection is an invasion and multiplication of pathogens in the body. In this case, the infection is H. pylori and the resulting inflammation is gastritis.

Helicobacter pylori in the stomach.
The bacterium responsible for 90% of gastritis cases lives in humans and is contracted as a child, many times.

Myth 2: If you eat citrus fruits you’ll get gastritis

Not true. Citrus fruits are acidic, but they don’t have the ability by themselves to cause gastritis. What they can cause is gastric reflux.

Gastroesophageal reflux is when stomach contents made up of hydrochloric acid, pepsin, and bile salts ascend into the esophagus and cause damage and discomfort. Citrus fruits cause reflux by lowering the pH of the stomach and stimulating the movement of liquid.

Myth 3: Starving yourself causes gastritis

This actually could be possible. If you fast frequently, then this can cause  gastric juices to come into direct contact with the empty stomach and increase the irritation of the mucosa.

In addition, in this situation there’s another aspect that can worsen the condition, as a certain amount of food can be ingested, making the stomach more sensitive. The best recommendation is to schedule 5 small meals a day to prevent this.

Myth 4: Analgesics and antibiotics cure gastritis

Not true. Neither painkillers nor antibiotics are able to cure gastritis or soothe it.

Painkillers are used against pain. Antibiotics, on the other hand, are used to fight infections caused by bacteria. Antibiotics are only prescribed if the gastritis was caused by a Helicobacter pylori infection.

Another medication recommended to treat gastritis is antacids. However, these aren’t able to cure, but simply to relieve symptoms for a short period of time.

What is prescribed for gastritis are proton pump inhibitors, which act by reducing the amount of gastric juice secretions. That’s why they’re called gastric protectors.
