As delivery food, instant meals, and stimulating dishes become part of daily life, more people are visiting hospitals for gastritis, stomach ulcers, and esophagitis. The problem is that diseases with high incidence rates in Korea, such as stomach cancer and esophageal cancer, often have almost no early symptoms. Siheung Janghyeon Internal Medicine systematically manages these gastrointestinal diseases, focusing on endoscopic examinations.
Heartburn and Indigestion: Can They Be Ignored?
Heartburn, indigestion, nausea and vomiting, abdominal pain, and general fatigue. These may seem like common digestive discomforts, but they could actually be signs of the following conditions:
- Gastritis, stomach ulcers
- Functional dyspepsia
- Helicobacter pylori infection
In particular, Helicobacter pylori is associated with the development of stomach cancer, yet most cases are asymptomatic, making it difficult to detect on your own. This is why regular gastroscopy is necessary for early detection.
What is Gastroscopy?
Gastroscopy is an examination where an endoscope with a special camera is inserted through the mouth to observe the mucous membranes of the esophagus, stomach, and duodenum in real-time. If you are concerned about pain, you can undergo a sedated endoscopy in a relaxed state. For elderly individuals or those with chronic diseases, a general endoscopy may be safer, so it is advisable to consult with medical staff first. If you are curious about the examination process, you can check the procedures in advance at Examination Guide.
What Can Be Confirmed Through the Examination
- Gastritis, stomach ulcers, esophagitis
- Presence of Helicobacter pylori infection
- Early detection of early-stage stomach cancer, esophageal cancer
Another advantage is that if abnormal findings are observed, a biopsy can be performed immediately, allowing for the prompt establishment of a treatment plan.
When and How Often Should I Get Examined?
| Target Group | Recommendation |
|---|---|
| Individuals aged 40 and over | Once every two years, in conjunction with national health screenings |
| Individuals with a family history of gastrointestinal disease | Voluntary examination even if not in the recommended age group |
| Individuals with persistent upper gastrointestinal symptoms | Examination recommended regardless of age |
