I have met Naeema Ginwala Hasan 3 times in the last couple of months after a Bupa health test showing elevated blood pressure and high cholesterol which has been an issue for a number of years. Naeema has been excellent in terms of explaining the issues the tests, which drugs she was prescribing and why. The outcome after only a month has been really pleasing and she has come across as being really invested in the outcome, getting the best result while taking time to understand my lifestyle and what could be changed. It has felt a very considered and personal prognosis as well as carefully explaining it all to me. She has been wonderful
