Gastritis? Why Your Stomach Is Burning & Medically Approved Next Steps

A burning stomach is often due to gastritis, an inflammation of the stomach lining; common triggers include H. pylori infection, frequent NSAID use, alcohol, and severe physical stress, and symptoms can include upper abdominal burning, nausea, bloating, and early fullness.

Medically approved next steps include seeing a clinician for evaluation and H. pylori testing or endoscopy when needed, using acid-reducing medicines, taking antibiotics if H. pylori is present, and adjusting NSAIDs while limiting alcohol and smoking; seek urgent care for vomiting blood, black stools, or severe pain. There are several factors to consider, and important details that could change your plan are outlined below.

Gastritis? Why Your Stomach Is Burning & Medically Approved Next Steps

If your stomach feels like it's on fire, you're not alone. Gastritis is a common condition that causes irritation or inflammation of the stomach lining. It can come on suddenly or develop slowly over time. For many people, it feels like burning, aching, or gnawing pain in the upper abdomen.

The good news? Most cases of gastritis are treatable once you understand what's causing it. Below, we'll break down what gastritis is, why it happens, what symptoms to watch for, and the medically approved next steps you should consider.


What Is Gastritis?

Gastritis is inflammation of the lining of your stomach. Your stomach normally produces strong acid to digest food. To protect itself, it also has a mucus barrier. When that protective barrier becomes weakened or damaged, stomach acid can irritate the lining, leading to inflammation.

Gastritis can be:

  • Acute gastritis – comes on suddenly, often with noticeable pain
  • Chronic gastritis – develops slowly and may last for months or years

Both forms deserve attention, especially if symptoms persist.


Common Symptoms of Gastritis

Not everyone with gastritis has symptoms. But when symptoms do occur, they may include:

  • Burning or aching pain in the upper abdomen
  • Nausea or vomiting
  • Feeling overly full after eating
  • Bloating
  • Loss of appetite
  • Indigestion
  • Belching

In more serious cases, symptoms may include:

  • Vomiting blood
  • Black or tarry stools
  • Severe abdominal pain
  • Dizziness or fainting

These severe symptoms can signal bleeding in the stomach and require urgent medical attention.


What Causes Gastritis?

Several factors can irritate the stomach lining and lead to gastritis. The most common causes include:

1. H. pylori Infection

A bacteria called Helicobacter pylori is one of the leading causes of chronic gastritis worldwide. Many people carry this bacteria without knowing it. Over time, it can damage the stomach lining and increase the risk of ulcers.

2. Frequent Use of NSAIDs

Pain relievers like:

  • Ibuprofen
  • Naproxen
  • Aspirin

can reduce the stomach's protective lining if used frequently or at high doses.

3. Alcohol

Heavy or regular alcohol use can irritate and erode the stomach lining, leading to gastritis.

4. Stress on the Body

Severe illness, major surgery, burns, or trauma can trigger acute gastritis. This is sometimes called "stress gastritis."

5. Autoimmune Conditions

In some cases, the immune system mistakenly attacks the stomach lining, leading to chronic inflammation.

6. Other Triggers

  • Smoking
  • Bile reflux
  • Certain infections
  • Older age (the stomach lining thins naturally over time)

Understanding the cause is key to proper treatment.


How Is Gastritis Diagnosed?

If your symptoms last more than a few days or keep coming back, it's time to speak to a doctor.

Your healthcare provider may recommend:

  • A physical exam
  • Blood tests
  • A stool test (to check for H. pylori)
  • A breath test for H. pylori
  • An upper endoscopy (a small camera used to look inside your stomach)

Testing helps confirm whether you truly have gastritis and identifies the cause.

Medically Approved Treatment for Gastritis

Treatment for gastritis depends on the cause. Most cases improve with a combination of medication and lifestyle changes.

1. Acid-Reducing Medications

Doctors often recommend:

  • Proton pump inhibitors (PPIs) – reduce acid production
  • H2 blockers – lower acid levels
  • Antacids – neutralize stomach acid

These medications allow the stomach lining to heal.

2. Antibiotics (If H. pylori Is Present)

If testing confirms H. pylori, your doctor will prescribe a combination of antibiotics plus acid-reducing medication. It's important to complete the full course of treatment.

3. Stop or Adjust NSAID Use

If pain relievers are the cause, your doctor may:

  • Lower your dose
  • Switch medications
  • Recommend taking them with food
  • Add stomach-protective medication

Never stop prescribed medication without speaking to your doctor first.

4. Reduce Alcohol and Smoking

Limiting alcohol and quitting smoking can significantly improve healing.


What to Eat (and Avoid) With Gastritis

There's no single "gastritis diet," but some foods are gentler on the stomach.

Often Better Tolerated:

  • Oatmeal
  • Bananas
  • Rice
  • Toast
  • Lean proteins (chicken, turkey, fish)
  • Cooked vegetables
  • Yogurt (if tolerated)

May Worsen Symptoms:

  • Spicy foods
  • Fried or fatty foods
  • Acidic foods (like citrus and tomato products)
  • Coffee
  • Carbonated drinks
  • Alcohol

Keeping a food diary can help you identify personal triggers.


Can Gastritis Go Away on Its Own?

Mild acute gastritis may improve on its own if the irritant (such as alcohol or NSAIDs) is removed.

However, chronic gastritis usually requires medical treatment, especially if caused by H. pylori or an autoimmune condition.

Left untreated, chronic gastritis can lead to:

  • Stomach ulcers
  • Bleeding
  • Anemia
  • Increased risk of stomach cancer (in rare, long-term cases)

This is not meant to alarm you—but it does highlight why persistent symptoms should not be ignored.


When to Seek Immediate Medical Care

Call a doctor or seek urgent care if you experience:

  • Vomiting blood
  • Black or tarry stools
  • Sudden, severe stomach pain
  • Fainting or weakness
  • Chest pain

These could signal internal bleeding or another serious condition.


Preventing Gastritis

While not all cases are preventable, you can reduce your risk by:

  • Limiting NSAID use
  • Taking medications with food when recommended
  • Reducing alcohol intake
  • Quitting smoking
  • Managing stress
  • Practicing good hygiene (to reduce H. pylori transmission)

Small changes can make a significant difference over time.


The Bottom Line

Gastritis is common, treatable, and manageable—but it shouldn't be ignored. A burning stomach is your body's way of signaling irritation or inflammation. While mild cases may resolve with simple adjustments, ongoing or severe symptoms deserve medical evaluation.

If you're experiencing concerning symptoms and want to assess whether they align with Gastritis, Ubie's free AI-powered symptom checker can provide you with personalized insights based on your specific situation in just 3 minutes.

Most importantly, speak to a doctor if your symptoms:

  • Last more than a few days
  • Keep returning
  • Interfere with eating or daily life
  • Include warning signs like bleeding or severe pain

Early diagnosis and proper treatment can prevent complications and help you feel better sooner.

Your stomach is resilient—but it needs the right care to heal.
