A US social media creator, Lex Banach, reports that she gained nearly 3 stone over about six months without changing her diet or exercise routine, moving from around 11st to 14st. In the accounts published by UK outlets, she says medical professionals identified an underlying condition as the likely cause of the rapid weight increase. After receiving treatment for that condition, she claims she lost about four stone, describing it as the result of “one treatment.” The articles emphasize her description of the timeline—unexpected weight gain followed by medical investigation—and her subsequent weight-loss outcome after treatment. The reporting is presented as a personal story, and the available text does not specify the exact diagnosis or the precise treatment details. Overall, the pieces focus on the contrast between unexplained weight gain and weight reduction after doctors determine an underlying driver, framed as an example of why clinicians may evaluate unexpected weight changes rather than attributing them only to lifestyle factors.
