About Mr Mahantesh Karoshi

Mr Mahantesh Karoshi is a highly experienced Consultant Gynaecologist with a specialist interest in minimally invasive treatments for fibroids, adenomyosis, and endometriosis. He sees private patients at 108 Harley Street, London, with a focus on reproductive health, benign gynaecological conditions, and innovative treatments that avoid unnecessary surgery.

With over a decade of experience, Mr Karoshi is known for combining advanced surgical expertise with a calm and considered approach to care. Following his medical training, he was awarded a prestigious fellowship by the Royal College of Obstetricians and Gynaecologists, which took him to Argentina to further his expertise in managing complex placental conditions after multiple caesarean sections.

He has led the introduction of fertility-preserving technologies, including being the first in his department to offer the TruClear system for uterine polyp removal—an approach that is less invasive and more suitable for women wishing to preserve fertility.

In recent years, his practice has expanded to include incision-free fibroid treatments such as Sonata and StarMed radiofrequency ablation. He has also adopted non-invasive diagnostic tools for conditions like endometrial cancer and endometriosis, including the use of WID-qC, advanced ultrasound, MRI, and newer tests such as Ziwig and Endosure.

Since joining the specialist register in 2010, Mr Karoshi has built a practice centred on truly listening to his patients. He recognises that each woman’s experience is unique and takes the time to investigate symptoms thoroughly, offering clear and individualised treatment options that reflect each patient’s needs and values.

His approach is compassionate, collaborative, and holistic. He believes in empowering women with knowledge, enabling them to make confident and informed decisions about their health at every stage of life.

Outside of his clinical work, Mr Karoshi is vegetarian, enjoys long-distance running, and practises meditation and classical music as ways to relax and recharge.

I would like to express my sincere thank you to Mr. Karashi, who performed the sonata treatment and hysteroscopic myomectomy. The operation went well and my period has become normal and much lighter after the operation. My tummy has less pressure to my lower back after both treatments. Mr. Karashi explained very well to me my symptoms and what caused my heavy period and pressure to my lower back. He is very patient and friendly and I feel that I am in a very good care of him. I would highly recommend Mr. Karashi to any patient who needs gynaecological treatment.

I recently underwent an open myomectomy performed by Mr Karoshi, and I cannot speak highly enough of the care I received. From the initial consultation through to the surgery and post-operative follow-up, he was exceptional - highly attentive, knowledgeable, and personable throughout. His calm manner and clear expertise put me completely at ease at every stage. My recovery has been far quicker than I expected, and I could not have hoped for a better experience. I would highly recommend Mr Karoshi.

Dr Karoshi was the first doctor to properly investigate my symptoms and confirm that my pain was real, diagnosing endometriosis, fibroids, and other underlying issues. Despite it being almost two years since my last visit, he remembered my case and made me feel truly heard. He guided me toward the most appropriate treatment, always aiming for the most effective option with the least harm and carefully considering alternatives to surgery. I am very grateful for his care and would highly recommend him.

My recent visit to Hadley Wood Hospital was very positive. From admission to discharge, the staff were professional, kind, and supportive. The process was well organised, and I felt well informed at each stage. Mr Karoshi explained the procedure clearly, addressed my concerns, and made me feel reassured throughout my care. Overall, I had a smooth and comfortable experience.

I began seeing Mr Karoshi after struggling to regain my period and following an NHS scan that detected an ovarian cyst. From the very first appointment, he was incredibly thorough, organising additional blood tests and scans to ensure we fully understood the situation before making any decisions. Mr Karoshi explains medical information very clearly and breaks everything down in a way that is easy to understand. He always took the time to listen, never rushed me, and patiently answered every one of my (many) questions. When it came to managing my cyst, Mr Karoshi outlined all possible options and explained the risks and benefits. He ensured I understood the different approaches and made me feel fully involved in my care. After some time, I decided to proceed with surgery, a decision I felt completely confident about because of his guidance and knowing I would be under his care. The surgery went smoothly, and Mr Karoshi took the time to check in with me immediately afterwards, again the next morning, and arranged a follow up appointment two weeks later. I am extremely grateful for the care I have received and feel very fortunate to have found Mr Karoshi. I couldn't recommend him more highly!
