Dr. Bounpheng Sisouphanthong

Dr. Bounpheng Sisouphanthong is a senior internist at Mahosot Hospital in Vientiane — Laos's leading referral and infectious disease hospital, with a long history of collaboration with the Wellcome Trust and international research institutions. With 14 years of internal medicine experience in one of Southeast Asia's most resource-limited but epidemiologically rich healthcare environments, he manages a diverse caseload spanning tropical infectious diseases, chronic hepatitis, liver disease, and the growing burden of non-communicable diseases. Mahosot Hospital has an internationally recognised infectious disease research unit, and Dr. Sisouphanthong works alongside research clinicians, giving his practice strong evidence-based foundations. His clinical interests span hepatology — hepatitis B and C are highly endemic in Laos — and tropical infectious diseases including malaria, typhoid, and dengue. He is committed to bringing international-standard internal medicine to Lao patients while mentoring the next generation of Lao physicians.

Dr. Sisouphanthong obtained his MD from the University of Health Sciences in Vientiane — Laos's national medical university. He subsequently completed a Postgraduate Diploma in Internal Medicine at Mahidol University in Bangkok, Thailand — one of Southeast Asia's strongest internal medicine programmes, which Lao physicians frequently access through bilateral training agreements. He also completed a Certificate in Tropical Medicine at Mahidol's Faculty of Tropical Medicine, deepening his expertise in malaria, parasitology, and vector-borne disease management. He attends the Lao Medical Association's annual scientific congress and Asian Pacific Association for the Study of the Liver (APASL) meetings for hepatology-specific professional development.

Dr. Sisouphanthong's internal medicine expertise is strongly shaped by Laos's epidemiological profile. Tropical infectious diseases — malaria (including complicated P. falciparum malaria), typhoid fever, dengue, scrub typhus, and melioidosis — form a major part of his acute inpatient work at Mahosot. His hepatology practice covers chronic hepatitis B and C (including antiviral therapy), liver cirrhosis management, portal hypertension, and hepatocellular carcinoma surveillance. He performs liver biopsy, ascitic fluid drainage for diagnostic and therapeutic purposes, and bone marrow aspiration. For non-communicable disease he manages type 2 diabetes, hypertension, and dyslipidaemia. He also diagnoses and manages tuberculosis and HIV/AIDS within his general internal medicine remit.

Dr. Sisouphanthong consults in Lao, Thai, and English. He is accessible to international travellers, expatriates, and NGO workers in Vientiane — particularly those who develop febrile illness during their time in Laos. Mahosot Hospital is the recommended referral point for complex medical presentations in Laos and has experience managing foreign patients. He advises international visitors to consult promptly if they develop fever with headache, rash, or constitutional symptoms after travel in rural Laos, where malaria and other tropical infections carry risk. For planned internal medicine consultations, appointments can be made through the hospital's outpatient department.

Dr. Sisouphanthong is a member of the Lao Medical Association and the Asian Pacific Association for the Study of the Liver (APASL). He collaborates with the Mahosot Hospital Wellcome Trust Research Unit and has contributed to clinical data collection for multi-centre tropical disease studies. He has been recognised by the Lao Ministry of Health for his contributions to training and to improving internal medicine service standards at Mahosot. He mentors final-year medical students and junior doctors rotating through internal medicine and infectious disease wards.
