Ogikubo Gastrointestinal Clinic, established in 1974, is a community medical facility conveniently located immediately west of JR Ogikubo Station, providing general internal medicine services centered in Suginami Ward. The clinic covers a broad range of internal medicine, from digestive disorders to cardiovascular, respiratory, and diabetes conditions. Transnasal endoscopy, crucial for early detection of gastric cancer, is performed under local anesthesia. Active treatments include gastric and colonic polypectomy, Helicobacter pylori eradication, and ulcerative colitis therapy, which has shown an increasing trend among younger patients in recent years. In addition to colds and lifestyle-related diseases, the clinic addresses AGA, ED, hay fever, and influenza vaccination, offering Kampo medicine treatments for menopausal symptoms, stiff shoulders, sensitivity to cold, and constipation. Treatment for dementia patients involves medical collaboration with university hospitals, while simple screening tests for sleep apnea syndrome and blood-based allergen testing for allergies are provided. Secondary detailed examinations following ward health checkups, comprehensive health screenings, and workplace health checkups are also available, with clinic operations maintained on both Saturdays and Sundays.
