I was curious for a UK comparison so I looked it up.
At the start of 2025, about 3% of adults in UK had used GLP-1 drugs in past year in the UK. And "most GLP-1 for weight loss in the UK is from private, rather than NHS provision" [1].
UK numbers are always interesting because the NHS leans conservative about access to many types of care and medication.
For another example, rates of COVID-19 vaccination are significantly lower in the UK not because people there don’t want vaccines, but because the NHS only makes them narrowly available to people above a certain age or with a strict set of conditions.
I assume that translates to it being really hard to get in the NHS so people are resorting to buying it themselves. I wonder what the percentage would be if it was easy to get from the NHS?
