Gastroenterology
Gastroenterology
Gastrointestinal diseases are among the most common conditions for which patients in Korea seek medical attention, encompassing both benign and malignant disorders.
In Korea, where the mortality rate from gastric cancer is high, the recent Westernization of dietary habits has led to an increased prevalence of colorectal cancer, inflammatory bowel disease, and irritable bowel syndrome. The prevalence of hepatitis B and C remains high, and liver cancer continues to rank among the leading causes of death in the country, thereby underscoring the importance of the gastroenterology field.
