Peptic Ulcer Disease: Symptoms, Causes, and Treatment

Peptic ulcer disease causes painful sores in your stomach lining or small intestine. The two main causes are H. pylori bacterial infection and long-term NSAID painkiller use. Symptoms include burning stomach pain, bloating, and nausea. Treatment involves antibiotics (if needed) and acid-reducing medications. Most ulcers heal within weeks with proper care.

What is Peptic Ulcer Disease: Symptoms, Causes, and Treatment?

Peptic ulcer disease causes painful sores in your stomach lining or small intestine. The two main causes are H. pylori bacterial infection and long-term NSAID painkiller use. Symptoms include burning stomach pain, bloating, and nausea. Treatment involves antibiotics (if needed) and acid-reducing medications. Most ulcers heal within weeks with proper care.

Symptoms

Early symptoms

  • Burning stomach pain: A gnawing or burning pain in your stomach between meals or at night. Often temporarily relieved by eating certain foods or taking antacids. (1) (8)
  • Bloating or fullness: Feeling uncomfortably full or bloated even after small meals. Some describe it as pressure or tightness in the stomach area. (1) (2)
  • Heartburn: A burning sensation rising from your stomach toward your chest, especially after eating. (8)
  • Nausea: Feeling queasy or sick to your stomach, sometimes accompanied by mild vomiting. (1) (2)
  • Intolerance to fatty foods: Fatty or greasy foods may trigger or worsen stomach discomfort after eating. (8)

Serious or emergency symptoms

  • Vomiting blood: Blood in vomit may appear bright red or look like coffee grounds. This indicates bleeding in the digestive tract. Seek emergency medical care immediately. (7) (8)
  • Black, tarry stools: Stools that are dark and sticky can signal bleeding higher up in your digestive system. Contact your doctor right away or go to emergency care. (7) (8)
  • Sudden severe abdominal pain: Sharp, worsening pain that doesn't go away could mean the ulcer has perforated (created a hole through the stomach wall). This is a medical emergency—call for emergency services. (7) (8)

Causes

Primary causes

  • H. pylori infection: This spiral-shaped bacterium damages the stomach's protective mucus coating, allowing acid to reach and damage the stomach lining. It's the most common cause of ulcers worldwide. (6) (3)
  • Regular NSAID use: Frequent use of pain relievers like ibuprofen (Advil, Motrin) or aspirin disrupts the stomach's protective mechanisms. Long-term NSAID use accounts for many ulcers not caused by H. pylori. (3) (8)

Risk factors

Long-term NSAID use

Regular use of NSAID pain relievers for chronic pain conditions significantly increases ulcer risk, especially at high doses or in older adults. (3) (8)

H. pylori infection

Living in crowded conditions or developing countries increases your exposure risk. The bacteria spread through contaminated food/water or close contact. (6)

Smoking

Tobacco use increases stomach acid production while decreasing protective factors, slowing ulcer healing and making recurrence more likely. (3)

Excessive alcohol

Heavy drinking can erode the stomach lining and increase acid production, though moderate drinking likely doesn't cause ulcers alone. (3)

Diagnosis

Your doctor will first ask about your symptoms and medication history. They may test for H. pylori using a blood, stool, or breath test. The most accurate test is an upper endoscopy - using a thin tube with a camera to look directly at your stomach lining and take biopsies if needed. Occasionally, a barium swallow X-ray may be used where you drink a chalky liquid that coats your digestive tract to make ulcers visible.

H. pylori breath test

Detects active H. pylori infection by measuring carbon dioxide in your breath after drinking a special solution. (4)

Stool antigen test

Checks for current H. pylori infection by detecting bacterial proteins in a stool sample. (4)

Upper endoscopy

Directly visualizes ulcers in the stomach and duodenum using a camera, allowing biopsies to test for H. pylori and rule out cancer. (4)

Treatment

Medication options

Antibiotics (for H. pylori)

Combination antibiotic therapy kills H. pylori bacteria. Usually two antibiotics are taken with acid-reducers for 10-14 days. (5) (4)

Proton pump inhibitors (PPIs)

Reduce stomach acid production significantly, allowing ulcers to heal. Usually taken for 4-8 weeks. (5) (2)

H2 blockers

Reduce acid production less powerfully than PPIs but may be used for maintenance after ulcers heal. (4) (2)

Lifestyle and self-care

  • NSAID alternatives: When possible, switch to pain relievers less likely to cause ulcers, like acetaminophen (paracetamol), under your doctor's guidance. If you must take NSAIDs, discuss using the lowest effective dose with PPIs. (5)
  • Avoid smoking and limit alcohol: Quitting smoking helps ulcers heal faster. Limit alcohol to no more than 1 drink per day to avoid irritating your stomach lining. (5)
  • Stress reduction: While stress doesn't cause ulcers, managing it may help symptoms. Techniques like meditation, gentle exercise, and adequate sleep can support healing. (5)

Always discuss dosing and treatment changes with your own prescriber.

Possible complications

  • Internal bleeding: Slow bleeding leads to anemia (fatigue, weakness); rapid bleeding can cause shock (pale skin, rapid pulse, fainting) and requires emergency treatment. (7) (8)
  • Perforation: When an ulcer creates a hole through the stomach wall, spilling stomach contents into the abdominal cavity. Causes sudden severe pain and requires emergency surgery. (7) (8)
  • Gastric outlet obstruction: Scarring from long-standing ulcers can narrow the stomach's exit, blocking food passage and causing vomiting, weight loss, and persistent fullness. (7)

When to see a doctor

Routine follow-up

  • Schedule an appointment if you experience persistent stomach pain, bloating, or heartburn that lasts more than a few days, even if symptoms come and go. (7) (8)

Seek emergency care

  • Seek emergency care immediately if you vomit blood (red or like coffee grounds), pass black/tarry stools, or have sudden severe abdominal pain that doesn't improve. (7) (8)
  • Call emergency services if you experience signs of shock: rapid heartbeat, shallow breathing, cold sweat, dizziness, or confusion - these can indicate severe internal bleeding. (7)

Frequently asked questions

How painful are stomach ulcers?

Pain varies—some feel mild gnawing discomfort, others have severe burning pain. The pain often comes and goes, frequently worsening when your stomach is empty (between meals or at night). Eating certain foods or taking antacids may temporarily relieve it. Severe persistent pain may indicate complications needing prompt care. (1) (8)

Can spicy foods give you ulcers?

While spicy foods don't cause ulcers, they may aggravate existing ones for some people. The real culprits are H. pylori infection and NSAIDs. If you have an ulcer, you might find symptom relief by avoiding foods that worsen your pain, including for some: spicy dishes, acidic foods (like citrus or tomatoes), and caffeinated drinks. (3) (8)

Do stomach ulcers heal on their own?

Some mild ulcers may temporarily improve without treatment, but proper medical care is essential. Untreated ulcers often come back and risk dangerous complications like bleeding or perforation. H. pylori ulcers won't fully heal until the bacteria are eliminated with antibiotics. Complete the full treatment your doctor prescribes even if you feel better sooner. (5) (4)

Is milk good for ulcers?

Milk provides quick temporary relief by coating the stomach, but it actually stimulates acid production soon after, which can worsen the ulcer long-term. While dairy in moderation isn't harmful, relying on milk as treatment delays proper care. The most effective approach combines medications (like PPIs and antibiotics if needed) with lifestyle adjustments. (5)

How do you prevent ulcers from coming back?

To prevent recurrence: complete all prescribed medications (especially antibiotics for H. pylori), use NSAIDs only when necessary (under doctor supervision), quit smoking, limit alcohol, manage stress, and maintain regular check-ups if you have ulcer history. If symptoms return, see your doctor promptly—don't self-medicate with antacids long-term. (5) (4)
