A peptic ulcer is an open sore that develops on the inner lining of the stomach or the upper part of the small intestine. It is a common digestive condition that can cause burning or discomfort in the upper abdomen, although some people may have an ulcer without noticeable symptoms.
The two most common causes of peptic ulcers are Helicobacter pylori (H. pylori) infection and regular use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen. When diagnosed and treated properly, most peptic ulcers can heal. However, untreated ulcers can sometimes cause serious complications, including bleeding or perforation.
What Is a Peptic Ulcer?
A peptic ulcer is a sore that forms in the protective lining of the digestive tract. Depending on where it develops, it may be called a gastric ulcer or a duodenal ulcer.
A gastric ulcer occurs inside the stomach, while a duodenal ulcer develops in the first part of the small intestine, known as the duodenum.
The digestive system normally has protective mechanisms that help shield its lining from stomach acid. When these defenses are weakened or damaged, acid and digestive juices can contribute to the development of an ulcer.
Common Symptoms of Peptic Ulcer
Some people with peptic ulcers have no symptoms. When symptoms occur, abdominal discomfort is one of the most common complaints.
Possible symptoms include:
- Burning or dull pain in the upper abdomen
- Stomach discomfort between meals
- Pain that may occur at night
- Bloating
- Nausea
- Vomiting
- Belching
- Feeling full sooner than usual
- Feeling unusually full after eating
- Heartburn in some people
The pattern of pain can vary. For some individuals, eating temporarily relieves discomfort, while for others, food may make the pain worse.
What Causes Peptic Ulcers?
H. pylori Infection
H. pylori is a bacterium that can live in the stomach and is one of the leading causes of peptic ulcers.
The infection can damage or weaken the stomach’s protective lining, allowing acid to contribute to ulcer formation.
Not everyone with H. pylori develops an ulcer, and many infected people may have no obvious symptoms. When an ulcer is associated with H. pylori, treating the infection is an important part of preventing recurrence.
NSAID Pain Relievers
Regular or prolonged use of NSAIDs is another major cause of peptic ulcers.
Common NSAIDs include:
- Aspirin
- Ibuprofen
- Naproxen
These medications can interfere with the stomach’s natural protective mechanisms and make the digestive lining more vulnerable to damage.
The risk can be greater with high doses, long-term use, multiple NSAIDs, or certain combinations of medicines.
Other Possible Causes
Less common causes can include certain infections, medical conditions affecting the digestive system, severe illness, and rare disorders that cause excessive stomach acid production.
Smoking can also increase the risk of ulcers and may slow healing. Alcohol can irritate the digestive lining and worsen symptoms.
Do Spicy Foods Cause Peptic Ulcers?
Spicy foods are commonly blamed for stomach ulcers, but they are not considered a primary cause of peptic ulcers.
Similarly, everyday stress does not directly cause most peptic ulcers. However, spicy foods, alcohol, or stress may make digestive symptoms feel worse in some people.
The major underlying causes remain H. pylori infection and NSAID use.
Peptic Ulcer vs Gastritis
Peptic ulcer and gastritis are related but different conditions.
Gastritis refers to inflammation or irritation of the stomach lining, whereas a peptic ulcer is an actual open sore in the stomach or duodenal lining.
Both conditions can cause upper abdominal pain, nausea, bloating, and indigestion. H. pylori and NSAIDs can also contribute to both conditions.
Because their symptoms can overlap, persistent stomach pain should not automatically be assumed to be gastritis or an ulcer without appropriate medical evaluation.
How Is a Peptic Ulcer Diagnosed?
A healthcare professional may begin by reviewing your symptoms, medical history, medications, and risk factors.
Tests may include:
H. pylori Testing
Doctors can test for H. pylori using methods such as:
- Breath testing
- Stool testing
- Blood testing in certain situations
Upper GI Endoscopy
An upper gastrointestinal endoscopy allows a healthcare professional to examine the esophagus, stomach, and duodenum using a small camera.
During the procedure, tissue samples may also be taken when necessary.
Endoscopy can help identify an ulcer and evaluate possible complications or other causes of symptoms.
How Is Peptic Ulcer Treated?
Treatment depends on the cause of the ulcer.
Treatment for H. pylori
When H. pylori is responsible, treatment generally involves a combination of medicines. This commonly includes multiple antibiotics along with an acid-reducing medicine such as a proton pump inhibitor.
In some treatment plans, bismuth may also be included.
It is important to complete the prescribed treatment because incomplete antibiotic therapy can allow the infection to persist and may contribute to antibiotic resistance. Follow-up testing may be recommended to confirm that H. pylori has been successfully eliminated.
Treatment for NSAID-Related Ulcers
If NSAIDs are contributing to an ulcer, a doctor may recommend changing, reducing, or stopping the medication when medically appropriate.
If an NSAID is still necessary, a healthcare professional may consider strategies to reduce the risk of further stomach damage, including acid-suppressing medication.
Acid-Reducing Medicines
Medicines that reduce stomach acid can help an ulcer heal.
These may include:
- Proton pump inhibitors (PPIs)
- H2-receptor blockers
- Other protective medicines in selected cases
Antacids may provide temporary symptom relief, but they generally are not the primary treatment used to heal an ulcer.
What Foods Should You Eat With a Peptic Ulcer?
There is no universal special ulcer diet. Research has not established that avoiding particular foods prevents or treats peptic ulcers.
However, people may notice that certain foods or drinks make their symptoms worse.
If a particular food causes discomfort, you can discuss dietary adjustments with a healthcare professional.
It may also be helpful to limit substances that irritate the digestive tract, particularly excessive alcohol.
Can a Peptic Ulcer Heal Completely?
Yes. Many peptic ulcers heal successfully when the underlying cause is identified and treated.
For example, an H. pylori-related ulcer requires appropriate treatment of the infection. An NSAID-related ulcer may improve after the responsible medication is adjusted or discontinued under medical guidance.
Taking prescribed medicines correctly and addressing the cause can also reduce the chance of recurrence.
Complications of Peptic Ulcer
Although many ulcers can be treated successfully, untreated or complicated ulcers can become serious.
Possible complications include:
Internal Bleeding
An ulcer may bleed slowly or rapidly. Signs can include black, tar-like stools or vomiting blood that may look bright red or resemble coffee grounds.
Perforation
A severe ulcer can create a hole through the stomach or intestinal wall. This can cause a serious abdominal infection called peritonitis.
Blockage
An ulcer can sometimes cause swelling or scarring that interferes with the movement of food through the digestive tract.
These complications require prompt medical attention.
When Should You See a Doctor?
You should seek medical evaluation if you have persistent or recurring upper abdominal pain, unexplained nausea, repeated indigestion, or symptoms that do not improve.
Seek urgent medical attention if you experience:
- Vomiting blood
- Vomit that looks like coffee grounds
- Black or tarry stools
- Blood in the stool
- Severe or sudden abdominal pain
- Fainting or significant dizziness
- Symptoms of possible shock
These can indicate bleeding or another serious ulcer complication.
How Can Peptic Ulcers Be Prevented?
Not every ulcer can be prevented, but several steps can reduce risk.
Use NSAIDs Carefully
If you regularly need aspirin, ibuprofen, naproxen, or another NSAID, talk with a healthcare professional about the safest option and dose.
Do not stop prescribed medication without medical advice.
Test and Treat H. pylori When Appropriate
If you have symptoms or risk factors that warrant testing, identifying and treating H. pylori can help reduce the risk of ulcer recurrence.
Avoid Smoking
Smoking can increase ulcer risk and may interfere with healing.
Limit Alcohol
Excessive alcohol can irritate the stomach lining and may worsen digestive symptoms.
Follow Your Treatment Plan
If you are diagnosed with an ulcer, taking your medicines exactly as prescribed is important for proper healing and prevention of recurrence.
Final Thoughts
A peptic ulcer is a sore that develops in the lining of the stomach or duodenum. Although it can cause burning abdominal pain, nausea, bloating, and other digestive symptoms, some people have no symptoms until a complication develops.
H. pylori infection and NSAID use are the two most common causes. Modern treatment can usually heal peptic ulcers by reducing stomach acid and addressing the underlying cause. H. pylori infections require appropriate eradication therapy, while NSAID-related ulcers may require medication adjustments.
If you notice persistent stomach symptoms—or especially vomiting blood, black stools, fainting, or severe abdominal pain—professional medical evaluation is important.
