The clinic offers internal medicine, gastroenterology, gastrointestinal medicine, cardiovascular medicine, lifestyle disease medicine, and rehabilitation services, addressing a wide range of symptoms and health concerns. Consultation hours are from 8:30 AM to 12:00 PM in the morning and 2:00 PM to 6:00 PM in the afternoon, with Thursday afternoons, Saturday afternoons, Sundays, and public holidays being closed. Diabetes outpatient services are available on Tuesday and Wednesday mornings and afternoons, emphasizing lifestyle disease management. In terms of equipment, the clinic has introduced transnasal endoscopy, allowing for less painful examinations by inserting a thin gastric camera through the nose. Colonoscopy examinations use carbon dioxide, which helps relieve abdominal bloating more quickly after the procedure, reducing post-examination discomfort. The clinic also features ultrasound bone densitometry and blood pressure pulse wave testing equipment, enabling checks for osteoporosis, arteriosclerosis, and narrowing or blockage of lower limb arteries. Nutritional guidance by a registered dietitian is provided, offering dietary support for patients with diabetes and lifestyle diseases. Patients with fever or infectious symptoms are also accepted, with sequential reception after preliminary telephone screening. As a primary care physician, the clinic provides health consultations and responds to inquiries during nights and holidays, and also accepts consultations for hospitalization and home visits.
