What Are Duodenal Ulcers?

A duodenal ulcer is an open sore that forms in the lining of the duodenum, which is the first part of the small intestine located just below the stomach.

It develops when the protective mucus lining is damaged, allowing stomach acid and digestive juices to irritate and erode the tissue.

Most duodenal ulcers are linked to Helicobacter pylori (H. pylori) infection, frequent or long term NSAID use, or excess stomach acid production. According to the National Institutes of Health, upper gastrointestinal Crohn disease involving the duodenum is uncommon, occurring in fewer than 4% of individuals with the condition.

Duodenal ulcers can cause burning upper abdominal pain that often worsens when the stomach is empty and may temporarily improve after eating. While many cases are treatable, untreated ulcers can lead to serious complications such as internal bleeding or intestinal perforation.

At Charleston GI, our board certified gastroenterologists diagnose and treat duodenal ulcers with targeted testing and personalized care, helping patients find relief and prevent complications.

Cause

Duodenal ulcers form when the protective mucus lining of the duodenum, the first part of the small intestine, becomes damaged. This allows stomach acid and digestive juices to injure the tissue and create an open sore.

Common causes include:

Bacterial infection

  • Helicobacter pylori (H. pylori) infection is the most common cause
  • The bacteria live in the digestive tract
  • They cause long term inflammation that weakens the protective lining

Medication irritation

  • Frequent or long term use of NSAIDs can damage the stomach and intestinal lining
  • These medications reduce the natural protective layer
  • Common examples include aspirin, ibuprofen & naproxen

Excess acid production

  • Some people produce too much stomach acid
  • Excess acid flows into the duodenum
  • This overwhelms the protective barrier and damages tissue

Risk Factors

Your risk of developing a duodenal ulcer increases with:

  • Untreated H. pylori infection
  • Regular use of NSAID pain relievers
  • Smoking or tobacco use, which slows healing and weakens the lining
  • Heavy alcohol use, which irritates the digestive tract
  • Severe physical illness or major medical stress, such as ICU care or ventilation support

Symptoms

Duodenal ulcers often cause burning or nagging pain in the upper abdomen.

Common symptoms include:

  • Hunger pain that appears when the stomach is empty, often 1 to 3 hours after eating
  • Night pain that may wake you from sleep
  • Temporary relief after eating or taking antacids
  • Bloating or fullness after small meals
  • Nausea and occasional vomiting
  • Unexplained weight loss due to reduced appetite or fear of eating

When to See a Doctor

Seek emergency care right away if you experience:

  • Sudden, severe stomach pain that does not improve
  • Vomiting blood or material that looks like coffee grounds
  • Black, tarry, or sticky stools

See a doctor if you notice:

  • Ongoing or worsening abdominal pain
  • Burning stomach discomfort that does not improve with over the counter medicine
  • Unexplained weight loss or poor appetite
  • Frequent nausea or vomiting
  • Feeling full quickly or unable to finish meals

Prompt evaluation helps prevent complications such as internal bleeding or perforation.

If symptoms are affecting daily life, Charleston GI offers direct access to testing and treatment without a referral. Schedule an appointment directly.

Diagnostic Test

Diagnosis may include a physical exam, symptom review, and specialized testing.

Upper endoscopy (EGD)

  • Most accurate test for duodenal ulcers
  • A thin tube with a camera is passed through the throat
  • Allows direct viewing of the esophagus, stomach, and duodenum
  • Tissue samples (biopsies) may be taken to test for H. pylori or other conditions

H. pylori testing

  • Breath test to detect bacterial byproducts
  • Stool test to check for bacterial proteins
  • Blood test to check for antibodies or anemia from internal bleeding

Treatment

Treatment depends on ulcer cause and severity.

  • Antibiotic therapy if H. pylori is present, usually 1 to 2 weeks
  • Acid reduction using proton pump inhibitors or H2 blockers
  • Protective medications to coat and support healing of the ulcer
  • Adjusting or stopping NSAID use when possible
  • Short term lifestyle and diet changes to support healing

Prevention & Lifestyle

  • Limit or avoid NSAIDs when possible
  • Wash hands regularly to prevent H. pylori infection
  • Stop smoking or using tobacco products
  • Manage stress to support digestive health

Foods and Drinks to Avoid or Limit

  • Coffee and caffeinated drinks, including decaf
  • Citrus fruits and acidic foods like tomatoes
  • Spicy foods and heavy seasoning
  • Alcohol
  • Fried and high fat foods
  • Late night meals close to bedtime

Foods & Drinks OK to Consume

  • Lean proteins like chicken, turkey, fish, and tofu
  • Whole grains such as oatmeal, brown rice, and whole grain bread
  • Non-acidic fruits like bananas, melons, and pears
  • Cooked vegetables such as carrots, green beans, and potatoes
  • Water for hydration and acid balance

FAQs

Diagnosis and Symptoms

According to the National Institutes of Health (NIH), both are peptic ulcers but form in different areas. A gastric ulcer develops in the stomach lining, while a duodenal ulcer forms in the duodenum, the first part of the small intestine.

A key difference is how eating affects pain. Gastric ulcer pain often worsens shortly after meals because food increases stomach acid. Duodenal ulcer pain is often relieved by eating or taking antacids because food temporarily buffers acid.

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), duodenal ulcer pain often worsens when the stomach is empty. Without food to buffer acid, stomach acid directly irritates the ulcer.

This is why symptoms commonly peak between meals and during the night.

According to peer reviewed medical literature on PubMed, a duodenal ulcer can sometimes cause referred pain that radiates to the back. This is more likely if the ulcer is on the posterior wall of the duodenum.

If the ulcer becomes deep or affects nearby organs such as the pancreas, it can cause severe back pain that needs urgent medical attention.

Urgency & Success Rate

A duodenal ulcer can become serious if it is not treated.

If left untreated, it may get worse over time and lead to complications such as:

  • Bleeding in the ulcer helps:
  • This can be mild, like slow bleeding
  • Or severe and life threatening if the bleeding is heavy

Endoscopy is a very effective treatment for stopping bleeding in a duodenal ulcer. The first treatment is successful in stopping bleeding in nearly 100% of cases.

After endoscopy treatment, about 85% to 90% of patients: Heal successfully or stop bleeding long term without needing surgery, according to the National Institutes of Health (NIH).

Causes and Triggers

According to the Centers for Disease Control and Prevention (CDC), Helicobacter pylori spreads through direct contact with saliva, vomit, or feces.

It can also spread through contaminated food or water. It is considered contagious and may spread among people living in the same household.

According to the American College of Gastroenterology, stress and spicy foods do not directly cause duodenal ulcers. The main causes are Helicobacter pylori infection and long term use of nonsteroidal anti-inflammatory drugs (NSAIDs).

However, stress and spicy foods can increase acid production and worsen symptoms.

According to the U.S. Food and Drug Administration (FDA), NSAIDs such as aspirin, ibuprofen, and naproxen should be avoided because they can damage the stomach and intestinal lining.

Acetaminophen is generally considered a safer option for pain relief, but you should confirm with your physician or gastroenterologist before use.

Diet and Management

According to medical universities and the Academy of Nutrition and Dietetics, no single food cures ulcers. However, a nutrient-rich, high-fiber diet may support healing.

Good options include:

  • Soluble fiber foods such as oats, barley, and cooked vegetables, which may help protect the digestive lining
  • Antioxidant-rich foods such as berries and leafy greens, which support overall digestive health

Certain drinks may soothe symptoms, while others can worsen irritation.

Helpful options include:

  • Water for hydration and acid dilution
  • Chamomile tea or ginger tea
  • Licorice root tea
  • Coconut water

Avoid or limit:

  • Alcohol
  • Coffee and other caffeinated drinks
  • Acidic or highly sugary beverages

According to Verywell Health and university health guidance, caffeine and alcohol can increase stomach acid and worsen symptoms.

To reduce irritation and excess stomach acid, it is generally recommended to avoid:

  • Alcohol
  • Caffeine
  • Spicy foods
  • Fried or greasy foods
  • Citrus fruits
  • Tomatoes
  • Processed meats

According to Verywell Health, these items may worsen symptoms by increasing acid production or irritating the stomach lining.

Yes. Ulcer-friendly meals do not need to be bland.

Mild, generally well-tolerated flavor options include:

  • Herbs such as parsley, dill, rosemary, and thyme
  • Small amounts of ginger
  • Light seasoning like soy sauce or coconut aminos

These can help improve taste without heavily irritating the stomach.

Because caffeine and alcohol can increase stomach acid, they are typically avoided.

Safer alternatives include:

  • Herbal teas such as chamomile, ginger, or licorice root tea
  • Water
  • Bone broth

These options are softer on the stomach and may help reduce discomfort.

No. According to gastroenterology resources, food cannot physically scratch a duodenal ulcer because it is broken down during digestion before reaching the small intestine.

However, some foods may still increase acid production or worsen symptoms.

Milk is not recommended as an ulcer treatment. According to Harvard Medical School, it may temporarily soothe symptoms but can later increase stomach acid production, which may worsen discomfort.

Clinical gastroenterology guidance suggests eating smaller, more frequent meals can help reduce symptoms.

A helpful approach includes:

  • Eating 5 to 6 small meals per day
  • Avoiding large meals that may overload the stomach
  • Choosing gentle, easy-to-digest foods

Treatment and Recovery

According to the Cleveland Clinic, most uncomplicated duodenal ulcers heal within four to eight weeks with proper treatment.

If H. pylori is present, antibiotics are typically taken for one to two weeks, along with acid reducing medication for the full healing period.

According to the NIDDK, untreated duodenal ulcers can lead to serious complications. These include internal bleeding, which may cause black stools or vomiting blood, and perforation, which is a hole in the intestinal wall.

Untreated ulcers can also cause scar tissue that may block food from leaving the stomach.

Ulcer Patient Concerns

According to FDA and NIH safety reviews, proton pump inhibitors are effective for short term healing but long term high dose use may carry risks.

These include reduced absorption of vitamin B12, magnesium deficiency, and increased risk of bone fractures. A physician should monitor long term use.

According to clinical sources, H. pylori treatment often involves multiple antibiotics.

Common side effects include nausea, diarrhea, abdominal discomfort, and a metallic taste. Despite side effects, completing the entire course is important to fully clear the infection.

According to the American College of Gastroenterology, symptoms can overlap, so diagnosis cannot be made based on pain alone.

Gastritis affects the stomach lining, duodenal ulcers are localized sores, and gallbladder issues often cause right upper abdominal pain after fatty meals.

Diagnostic testing like endoscopy or ultrasound is necessary for confirmation.

It is unlikely for an active duodenal ulcer to be missed on a proper endoscopy.

If symptoms continue, other conditions such as functional dyspepsia or early inflammation may be considered.
