Mr Mahantesh Karoshi
Professional statement
Mr Mahantesh Karoshi is a London-based women’s health expert and consultant gynaecologist, with a special interest in ovarian cysts, heavy menstrual bleeding, infertility, fibroids, and adenomyosis. He is currently one of the most highly-rated gynaecologists in London with a very good reputation amongst his patients and peers.
Mr Karoshi's work is recognised internationally, having volunteered in Ethiopia’s Gimbie Hospital, and later receiving the Bernhard Baron Travelling Fellowship from the Royal College of Obstetricians and Gynaecologists which led to his work in the University of Buenos Aires. Here he worked on the techniques needed to surgically manage morbidly adherent placental disorders - a serious condition that can occur in women with multiple caesarean sections.
He believes in an open doctor-patient relationship, being sure to include the patient and educating them so that they understand their condition better and they can be directly involved in their care and management at every stage. Aside from his clinical work, he is actively involved in research, which together with his experience, has given him the opportunity to publish the first stand-alone textbook on postpartum haemorrhage which was launched by HRH Princess Anne.
At the core of Mr Karoshi's practice is a high standard of professionalism where patients are involved in their treatment and where the latest techniques and advancements are used to provide an extremely high level of care.
