I think the key here is that you should be talking about blood sugar control and not weight loss. If you are on the Ascend Plus trial it is for people with Type 2 diabetes. There are also more effective drugs for weight loss available through private prescription.
Rybelsus is not allowed to be prescribed for weight loss on the NHS, but it is prescribed for blood sugar control in type 2 diabetics, so you would not help your case by talking about weight loss, although that might happen, it also might not and is not a reason for them to prescribe the Rybelsus according to NICE guidelines, and also the use of Rybelsus for weight loss is off label.
The NHS is allowed to prescribe Wegovy (semaglutide) and Mounjaro (tirzepatide) for weight loss as far as I know, but it would be for people with a high BMI and with other co-morbidities, which rules many people out, and is subject to both the NICE and the local guidelines.
I was prescribed Rybelsus after requesting it at my GP practice on realising that I was on the placebo. Also pertinent to this is that I had tried Metformin and could not tolerate it, and that I would not be able to take any SGLT 2 inhibitor drugs as that would be the next line they would try, as I am on a low carb diet, and there can be a risk of DKA if you are low carb on SGLT2 inhibitor drugs. I was not prepared to up the carbs in my diet as the low carb approach was having a huge effect on both weight loss and bringing the blood sugar down.
I did the research and got ready to make my case with a list of reasons why I should be prescribed Rybelsus, but just looking at my results for blood sugar control (from my CGM) while I was on the run in and then the placebo was enough for them to prescribe the Rybelsus, and they are happy to carry on after my excellent HbA1c result this month after 3 months of the prescribed Rybelsus. See my signature for the results.
I have also lost weight, but this is mainly because of my low carb diet and exercise, and not really as much to do with the Rybelsus - the big effect the Rybelsus had was on my blood sugar, and in normalising my insulin response, and helping with the fatty liver.
It has been decided to keep me on the 7mg dose as this is working well to control the blood sugar numbers.
