Scottish woman on weight loss injection: “Lost 55 kilos and clumps of hair”

On her social media channel Tikok, Kelsey takes people along on her journey to her new, slimming life. "I've changed my life 1000% and I don't regret it one bit," she says.

The Scot also writes: "At 10 kilos, it's not just about the scales... it's about finally getting rid of the baggy black clothes and feeling free to wear what I want."

And yet her preferred treatment, the Mounjaro weight-loss injection, also has its downsides. "I was losing clumps of hair," Kelsey confessed. In a video, she explains : "My hair loss was really, really bad. I was standing in the shower, brushing my hair—it was just everywhere."

This side effect is by no means the only one. Experts warn of other undesirable effects. Endocrinologist Stephan Martin explains the risks and long-term consequences of weight loss injections in general:

Studies have shown that the injections can lead to weight loss of up to 20 percent. However, side effects such as nausea and vomiting can occur when first used. Some believe these side effects may even contribute to weight loss.

A significant problem that is being intensively discussed internationally is the potential loss of muscle mass during rapid weight loss through weight loss injections. After stopping the injections, weight often rebounds, with the buildup of primarily fat mass. Thus, muscle is effectively exchanged for fat – an unhealthy and undesirable effect.

However, it is possible to maintain muscle mass during weight loss. A high-protein diet combined with exercise can help protect muscle mass. Although weight loss is somewhat slower this way, health remains the priority.
