He cautioned that they can lead to a reduction in bone density.‌These drugs, also known as GLP-1 inhibitors, work by utilising GLP-1 (glucagon-like peptide-1), a hormone produced in the gut that assists in regulating blood sugar and appetite.‌The popularity of GLP-1 inhibitors has rocketed in recent years, owing to their success in managing blood sugar levels in diabetic patients and supporting weight loss. Available in injection form, some of these medicines can be prescribed through the NHS for those who qualify.‌However, as with any medication, they can trigger unwanted side effects. Speaking on TikTok, Doctor Karan Rajan shed further light on the issue.Dr Rajan, widely known as Dr Raj, said: "If you're on a GLP-1, you can lose bone density." He was quick to point out, though, that this can occur with any type of weight loss.He continued: "But any weight loss can cause that. There's no plausible biological mechanism by which semaglutide, tirzepatide, or any GLP-1 medication directly contributes to bone loss or activates osteoclasts, the cells that break down bone, or blocks osteoblasts, the cells that build bone."‌He went on to explain: "GLP-1 receptors exist in bone tissue. And in pre-clinical studies, GP-1s appear to have neutral or even protective benefits."View 3 ImagesGLP-1 (glucagon-like peptide-1) is a hormone produced in the gut that helps control blood sugar and appetite(Image: Getty)Shedding weight "very quickly" by any method can have an impact on your bones, he warned.
