Common questions
Frequently asked questions
Answers to the questions patients most often ask about bariatric and general surgery in London, fees, locations and insurance.
Where in London does Miss Anna Kamocka see private patients?
Miss Kamocka sees private patients at three Central London locations: the Chelsea Wing at Chelsea and Westminster Hospital (369 Fulham Road, SW10 9NH), the Chelsea Outpatient Centre (280 King's Road, SW3 4NX) and One Welbeck Digestive Health (1 Welbeck Street, W1G 0AR, near Harley Street in Marylebone). Her NHS practice and surgical training base is at West Middlesex University Hospital, Isleworth, and she also holds consultations at the Lister Hospital, Chelsea.
What weight loss surgery options does Miss Kamocka offer in London?
Miss Kamocka performs the full range of minimally invasive (laparoscopic / keyhole) bariatric surgery: gastric sleeve (sleeve gastrectomy), gastric bypass and revisional bariatric surgery for patients who have had previous weight loss surgery. She also performs metabolic surgery for type 2 diabetes — the subject of her PhD at Imperial College London — and provides comprehensive obesity management within a multidisciplinary team.
How much does a private consultation with Miss Kamocka cost?
A first private consultation starts from £300, and follow-up consultations start from £250. Online e-Consultations (private messaging and video) are also available. Surgical packages are quoted individually after your consultation, and insured patients should obtain pre-authorisation from their insurer.
Is Miss Anna Kamocka GMC registered?
Yes. Miss Anna Kamocka holds full GMC registration with licence to practise, number 6152928, verifiable on the General Medical Council's online register. She is a Fellow of The Royal College of Surgeons of England (FRCS).
Does Miss Kamocka accept private medical insurance?
Yes. Miss Kamocka is recognised by most major private medical insurers including Bupa, AXA Health, Aviva, Cigna, WPA, Simplyhealth, Allianz, Vitality and Benenden Health. If you hold private medical insurance, contact your insurer for a pre-authorisation number before booking your appointment.
Can bariatric surgery help with type 2 diabetes?
Yes — for many patients. Metabolic (bariatric) surgery is an evidence-based treatment for type 2 diabetes in patients with obesity and can lead to significant improvement or remission. Miss Kamocka's PhD research at Imperial College London focused specifically on bariatric surgery and diabetes remission. Suitability is always assessed individually within a full multidisciplinary work-up.
What is the difference between a gastric sleeve and a gastric bypass?
A gastric sleeve removes about 75–80% of the stomach, leaving a narrow tube that restricts how much you can eat and reduces appetite hormones. A gastric bypass reroutes the small intestine to a small stomach pouch, combining restriction with changes to gut hormones and mild malabsorption. Both are performed laparoscopically (keyhole). Miss Kamocka will discuss which option best fits your health, anatomy and goals at consultation.
How do I request an appointment with Miss Anna Kamocka in London?
You can request an appointment in three ways: call the practice on +44 (0)20 3038 2417 (Chelsea and Westminster), +44 (0)20 3433 1162 (Chelsea Outpatient Centre) or +44 (0)1865 649894 (One Welbeck); book online via her Top Doctors profile; or request an e-Consultation (private messaging and video consultation).
