Gastritis is a common condition that affects the stomach. It happens when the lining of your stomach becomes swollen or inflamed. Many people suffer from gastritis at some point in their life, and it can be mild or severe. In this article, we will explain what gastritis is, its causes, symptoms, treatments, and how you can prevent it in everyday life.

What Is Gastritis?
Gastritis means the lining of the stomach is irritated or inflamed. The stomach lining helps protect your stomach from strong stomach acids that help break down food. When this lining becomes weak or damaged, the stomach acid can hurt the tissues and cause inflammation.
There are two main types of gastritis:
Acute Gastritis
Acute gastritis happens suddenly and usually doesn’t last long. It can cause pain or discomfort in your upper stomach and may come with nausea or vomiting.
Chronic Gastritis
Chronic gastritis develops slowly over time. It can last for months or even years if not treated. It often causes long-term damage to the stomach lining and may lead to other problems.
Causes of Gastritis
There are many reasons why someone may get gastritis. Some causes are due to lifestyle habits, while others are related to infections or health conditions.
Common Causes
- Infections – The most common cause of chronic gastritis is a bacteria called Helicobacter pylori (H. pylori).
- Pain relievers – Taking too many non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin can hurt the stomach lining.
- Alcohol – Drinking too much alcohol can irritate and wear down the stomach lining.
- Stress – Severe stress from surgery, injury, or illness can lead to sudden gastritis.
- Bile reflux – When bile (a fluid from the liver) backs up into the stomach, it can cause gastritis.
- Autoimmune diseases – In some people, the immune system attacks the stomach lining by mistake.
Symptoms of Gastritis
The symptoms of gastritis can vary from person to person. Some people may not feel any symptoms at all, especially in the early stages.
Common Symptoms
- Pain or burning feeling in the upper stomach
- Nausea or vomiting
- Feeling full quickly during meals
- Loss of appetite
- Bloating or burping
- Indigestion
- Black or tarry stool (a sign of bleeding in the stomach)
If you have any of these symptoms for more than a few days, you should see a doctor to find out the cause.
How Gastritis Is Diagnosed
To find out if you have gastritis, your doctor may ask about your symptoms, medical history, and lifestyle habits. They may also suggest tests such as:
Medical Tests
- Blood test – To check for infections or anemia.
- Stool test – To find signs of H. pylori or blood in your stool.
- Breath test – A special test to check for H. pylori bacteria.
- Endoscopy – A thin tube with a camera is passed through your throat into your stomach to look at the lining.
- Biopsy – A small piece of stomach tissue may be taken during endoscopy to check for infection or other problems.
Treatment for Gastritis
The treatment for gastritis depends on what is causing it. The goal is to reduce stomach acid and treat any infections.
Common Treatments
- Antibiotics – If H. pylori bacteria are found, antibiotics can be used to get rid of them.
- Antacids – These help neutralize stomach acid and give quick relief.
- Proton pump inhibitors (PPIs) – These reduce acid production (examples include omeprazole and lansoprazole).
- H2 blockers – These also reduce acid and help heal the stomach lining (examples include ranitidine and famotidine).
- Stop irritants – You may need to stop drinking alcohol, quit smoking, or stop taking NSAIDs.
Always follow your doctor’s advice when taking medicine for gastritis.
Home Remedies for Gastritis
Along with medicine, some natural remedies and lifestyle changes can help reduce gastritis symptoms and support healing.
Helpful Home Tips
- Eat smaller meals – Eating less at one time can reduce pressure on your stomach.
- Avoid spicy and acidic foods – These can irritate your stomach lining.
- Drink water often – Staying hydrated helps your stomach work better.
- Try ginger or chamomile tea – These are calming and may help with nausea and pain.
- Use probiotics – Found in yogurt and fermented foods, probiotics help fight harmful bacteria.
Foods to Eat and Avoid
What you eat can affect how your stomach feels. A good diet can help manage and prevent gastritis.
Foods to Eat
- Cooked vegetables (like carrots, broccoli, spinach)
- Whole grains (rice, oats)
- Lean meats (chicken, turkey)
- Fish
- Yogurt with probiotics
- Bananas and apples
- Herbal teas
Foods to Avoid
- Spicy foods
- Fried or fatty foods
- Citrus fruits (like oranges and lemons)
- Coffee and cola drinks
- Alcohol
- Processed foods
Who Is at Risk for Gastritis?
Gastritis can affect people of all ages, but some are at higher risk than others.
Risk Factors
- People who take painkillers regularly
- People with H. pylori infection
- Heavy alcohol drinkers
- People under stress
- Older adults (the stomach lining becomes thinner with age)
- People with autoimmune disorders
Possible Complications
If gastritis is not treated, it can lead to more serious problems.
Long-Term Risks
- Stomach ulcers – Open sores in the stomach lining
- Bleeding in the stomach
- Anemia – Due to blood loss
- Stomach cancer – Especially in chronic gastritis caused by H. pylori
This is why it’s important to treat gastritis early and follow your doctor’s advice.
How to Prevent Gastritis
You can reduce your chances of getting gastritis by making simple changes to your daily habits.
Prevention Tips
