Welsh NHS Weight Management Waiting Lists Hit 10 Years, Forcing Patients Private for Mounjaro

Waiting times for NHS weight management services in parts of Wales have reached an unprecedented 10 years, with some health boards seeing a doubling or quadrupling of their lists. This forces many patients to seek private alternatives, often without adequate medical oversight.

Hannah Long, 34, from Aberdare, diagnosed with polycystic ovary syndrome (PCOS), faced a minimum two-year wait at Cwm Taf Morgannwg health board. With 3,146 people on the waiting list in March 2025, up from 1,604 a year prior, she resorted to purchasing Mounjaro privately in October 2025, spending £1,000 in six months to lose four stone.

Ms. Long expressed concern over the lack of doctor supervision, stating, "I don't want to be on a drug that isn't monitored by a doctor." She also highlighted the "massive disparity between England and Wales," where Mounjaro became available via GP surgeries in England in June 2025, but in Wales remains largely restricted to specialist services or pre-surgery contexts.

Rachel Bevan, 40, from Bridgend, with a BMI over 45, also acquired Mounjaro through an online pharmacy starting in June 2024. She lost five stone but noted the escalating monthly cost, from £80 to £130, which she described as unsustainable for many. Ms. Bevan articulated a common sentiment, wishing the treatment had been available years ago to reclaim "so much of my life being overweight and miserable."

The National Institute for Health and Care Excellence approved tirzepatide (Mounjaro) in December 2024. Subsequently, Cardiff and Vale health board reported a 98% increase in referrals for weight-loss injections, prompting concerns about overwhelming the NHS and leading to a projected 12-year rollout period for the treatment.

The Welsh government stated it is considering future arrangements, including primary care provision, to address "considerable demand for weight management medicines and growing pressure for access through the NHS." They emphasised that these are prescription-only medicines that should only be obtained from reputable, registered pharmacies.

Opposition parties have criticised the current approach. Welsh Labour highlighted existing access for those with urgent surgical needs. Plaid Cymru called for a new focus on preventative care. Conservative health spokesman Peter Fox suggested that appropriately prescribed weight-loss medications could yield long-term savings for the health service. The Welsh Liberal Democrats demanded proper investment in NHS capacity and equitable access.
