Why this is checked during the medical evaluation
To distinguish between the risk of bleeding and remaining indigestion, it is necessary to know about the use of nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, or anticoagulants, as well as Helicobacter treatment and previous ulcer or endoscopy results.

Connecting Peptic Ulcers to My Symptoms

It is not the same as gastritis or functional dyspepsia

Gastritis refers to inflammation of the stomach lining, whereas an ulcer refers to a deeper sore in the lining of the stomach or duodenum. Since it is difficult to distinguish them by epigastric pain and satiety alone, endoscopy, Helicobacter tests, and current medications are reviewed.

Re-evaluating the cause of stomach discomfort even after ulcer treatment

Even after the ulcer has healed and the cause has been treated, bloating, early satiety, or epigastric pain may persist. While following the re-examination plan and current medication, we check for concurrent functional dyspepsia or reflux to set the goals for herbal medicine treatment.

Frequently Asked Questions

Frequently Asked Questions about Peptic Ulcers

If I have a burning sensation in my epigastrium on an empty stomach, is it a gastric ulcer?

It cannot be determined by that symptom alone. Since ulcers, gastritis, and functional dyspepsia can be similar, we check for the use of nonsteroidal anti-inflammatory drugs (NSAIDs), Helicobacter status, and other necessary tests.

Can I take herbal medicine while being treated for an ulcer?

Treating bleeding and the ulcer is the priority. Please inform both your medical staff and the Korean medicine doctor about any acid suppressants, eradication drugs, or nonsteroidal anti-inflammatory drugs (NSAIDs) you are taking, as well as your liver and kidney status, to determine if concurrent treatment is appropriate.
