Doctors in the UK are reporting patient harm linked to illegal weight-loss injections, as demand for appetite-suppressing drugs such as Wegovy, Ozempic and Mounjaro continues to rise. According to the accounts cited by multiple outlets, a significant share of general practitioners say they have treated patients who later needed hospital care after using so-called black-market or counterfeit versions of these medicines. The coverage frames the issue as a “fake fat jab” crisis, with concerns that counterfeit products may not contain the correct ingredients, dosage, or sterility standards expected of licensed treatments. The reports indicate that primary care clinicians are encountering cases where patients present with complications following prior use of unregulated injections obtained outside formal prescribing channels. The stated focus across sources is on patient safety and the health risks posed by unapproved medicines circulating amid increasing public demand for weight-loss drugs. The outlets call attention to the potential for counterfeit medication to contribute to adverse outcomes that can require urgent medical intervention.
