Gastroenterology Care

Digestive symptoms deserve more than temporary relief.

The digestive system includes the esophagus, stomach, small intestine, colon, liver, gallbladder and pancreas. Problems in different organs may produce similar symptoms, including abdominal pain, bloating, nausea, reflux or changes in bowel habits.

Short-lived digestive symptoms may improve without extensive testing. However, persistent, recurrent or worsening symptoms may require laboratory testing, stool testing, imaging, gastroscopy or colonoscopy.

At Apgujeong Hana Clinic, your symptoms are reviewed by a gastroenterology specialist who can coordinate medical treatment, digestive testing and endoscopy when appropriate.

🔥 Upper Digestive Symptoms Heartburn, indigestion, nausea, swallowing concerns and upper-abdominal discomfort.
🌀 Bowel Symptoms Constipation, diarrhea, abdominal cramping, bloating and changes in stool pattern.
🧫 Infection & Inflammation H. pylori, gastritis and other causes of stomach or intestinal inflammation.
🫁 Liver Health Fatty liver, elevated liver enzymes and metabolic liver-risk assessment.

Digestive Evaluation

Testing is selected according to your symptoms and risk.

Not every patient needs endoscopy. Your doctor first reviews the clinical pattern and then recommends the most useful next step.

🗂️ Medical History Review Symptom timing, meals, bowel pattern, medicines, family history and previous results are reviewed.
🧪 Blood Testing May include blood count, liver tests, inflammation markers, nutritional markers or other targeted testing.
🧫 Stool Testing Stool tests may help investigate infection, inflammation, bleeding or selected causes of chronic diarrhea.
🦠 H. pylori Testing Breath testing, stool testing or biopsy-based testing may be considered depending on the situation.
🖥️ Abdominal Imaging Ultrasound or other imaging may be useful for liver, gallbladder or selected abdominal concerns.
📹 Gastroscopy Examines the esophagus, stomach and upper small intestine when upper digestive symptoms require direct evaluation.
🔬 Colonoscopy Examines the colon for bowel symptoms, bleeding, polyps, inflammation or cancer screening.
📊 Liver Risk Assessment Liver enzymes, metabolic risk factors and imaging may be reviewed for fatty liver disease.
🧭 Follow-Up Planning Results are used to create a treatment, monitoring, eradication or additional-testing plan.
📌
Similar symptoms can require different treatments

Heartburn, upper-abdominal pain, bloating and bowel changes may result from reflux, gastritis, infection, IBS, medication effects or other conditions. Treatment should follow an appropriate diagnosis rather than symptoms alone.
