MMSN is a society of doctors, medical students and allied health professionals interested and involved in mountain medicine, high altitude physiology and related maladies. We are a non-governmental, not-for-profit organization working to understand and explore the science behind altitude related illnesses and utilizing this knowledge in making our mountains safer. Our regular activities include: journal clubs where we discuss and do critical appraisal of research papers on high altitude and wilderness medicine; national and international seminars and workshops; health camps for pilgrims; research on altitude related illnesses; publication of newsletters and books; and awareness programs on high altitude illnesses targeting trekkers, pilgrims and porters going to high altitude. We also provide doctors experienced in high altitude medicine to accompany researchers, trekkers, climbers and pilgrims, or to be temporarily stationed in high altitude aid posts in the remote areas of the Nepalese Himalayas during peak seasons.
