Overview

Peptic ulcers are open sores that develop on the inside lining of your stomach and the upper portion of your small intestine. The most common symptom of a peptic ulcer is stomach pain.

Peptic ulcers include:

Gastric ulcers that occur on the inside of the stomach
Duodenal ulcers that occur on the inside of the upper portion of your small intestine (duodenum)

The most common causes of peptic ulcers are infection with the bacterium Helicobacter pylori (H. pylori) and long-term use of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) (Advil, Aleve, others). Stress and spicy foods do not cause peptic ulcers. However, they can make your symptoms worse.

Symptoms

Gallstones may cause no signs or symptoms. If a gallstone lodges in a duct and causes a blockage, the resulting signs and symptoms may include:

Burning stomach pain
Feeling of fullness, bloating or belching
Fatty food intolerance
Heartburn
Nausea

The most common peptic ulcer symptom is burning stomach pain. Stomach acid makes the pain worse, as does having an empty stomach. The pain can often be relieved by eating certain foods that buffer stomach acid or by taking an acid-reducing medication, but then it may come back. The pain may be worse between meals and at night.

Nearly three-quarters of people with peptic ulcers don't have symptoms.

Less often, ulcers may cause severe signs or symptoms such as:

Vomiting or vomiting blood — which may appear red or black
Dark blood in stools, or stools that are black or tarry
Trouble breathing
Feeling faint
Nausea or vomiting
Unexplained weight loss
Appetite changes

Risk factors

In addition to taking NSAIDs, you may have an increased risk of peptic ulcers if you:

Smoke. Smoking may increase the risk of peptic ulcers in people who are infected with H. pylori.
Drink alcohol. Alcohol can irritate and erode the mucous lining of your stomach, and it increases the amount of stomach acid that's produced.
Have untreated stress.
Eat spicy foods.

Causes

Peptic ulcers occur when acid in the digestive tract eats away at the inner surface of the stomach or small intestine. The acid can create a painful open sore that may bleed.

Your digestive tract is coated with a mucous layer that normally protects against acid. But if the amount of acid is increased or the amount of mucus is decreased, you could develop an ulcer. Common causes include:

A bacterium. Helicobacter pylori bacteria commonly live in the mucous layer that covers and protects tissues that line the stomach and small intestine. Often, the H. pylori bacterium causes no problems, but it can cause inflammation of the stomach's inner layer, producing an ulcer. It's not clear how H. pylori infection spreads. It may be transmitted from person to person by close contact, such as kissing. People may also contract H. pylori through food and water.

Regular use of certain pain relievers. Taking aspirin, as well as certain over-the-counter and prescription pain medications called nonsteroidal anti-inflammatory drugs (NSAIDs) can irritate or inflame the lining of your stomach and small intestine. These medications include ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve, Anaprox, others), ketoprofen and others. They do not include acetaminophen (Tylenol).

Peptic ulcers are more common in older adults who take these pain medications frequently or in people who take these medications for osteoarthritis.

Other medications. Taking certain other medications along with NSAIDs, such as steroids, anticoagulants, low-dose aspirin, selective serotonin reuptake inhibitors (SSRIs), alendronate (Fosamax) and risedronate (Actonel), can greatly increase the chance of developing ulcers.

Treatment

Treatment for peptic ulcers depends on the cause. Usually treatment will involve killing the H. pylori bacterium, if present, eliminating or reducing use of NSAIDs, if possible, and helping your ulcer to heal with medication.

Medications can include:

Antibiotic medications to kill H. pylori. If H. pylori is found in your digestive tract, your doctor may recommend a combination of antibiotics to kill the bacterium. These may include amoxicillin (Amoxil), clarithromycin (Biaxin), metronidazole (Flagyl), tinidazole (Tindamax), tetracycline (Tetracycline HCL) and levofloxacin (Levaquin). The antibiotics used will be determined by where you live and current antibiotic resistance rates. You'll likely need to take antibiotics for two weeks, as well as additional medications to reduce stomach acid, including a proton pump inhibitor and possibly bismuth subsalicylate (Pepto-Bismol).

Medications that block acid production and promote healing. Proton pump inhibitors — also called PPIs — reduce stomach acid by blocking the action of the parts of cells that produce acid. These drugs include the prescription and over-the-counter medications omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), esomeprazole (Nexium) and pantoprazole (Protonix). Long-term use of proton pump inhibitors, particularly at high doses, may increase your risk of hip, wrist and spine fracture. Ask your doctor whether a calcium supplement may reduce this risk.

Medications to reduce acid production. Acid blockers — also called histamine (H-2) blockers — reduce the amount of stomach acid released into your digestive tract, which relieves ulcer pain and encourages healing. Available by prescription or over-the-counter, acid blockers include the medications ranitidine (Zantac), famotidine (Pepcid), cimetidine (Tagamet HB) and nizatidine (Axid AR).

Antacids that neutralize stomach acid. Your doctor may include an antacid in your drug regimen. Antacids neutralize existing stomach acid and can provide rapid pain relief. Side effects can include constipation or diarrhea, depending on the main ingredients. Antacids can provide symptom relief, but generally aren't used to heal your ulcer.

Medications that protect the lining of your stomach and small intestine. In some cases, your doctor may prescribe medications called cytoprotective agents that help protect the tissues that line your stomach and small intestine. Options include the prescription medications sucralfate (Carafate) and misoprostol (Cytotec).
