Alarming surge in severe obesity among adolescents in Ireland

Since 2018, Ireland has witnessed a tenfold increase in referrals of adolescents to specialised obesity clinics, highlighting a critical and worsening health issue among young people. Dr. Órla Walsh, a paediatric specialist at Children’s Health Ireland in Temple Street, has expressed deep concern over the rising number of young patients exhibiting severe symptoms of obesity. Over the past six years, the situation has escalated, with Dr. Walsh noting the overwhelming demand for treatment at her medically-led complex obesity clinic. “I’m running a clinic that is merely the tip of the iceberg. It is a tertiary clinic, which means we only see cases of severe complex obesity that also present with at least two other complications. Since its inception last year, our waiting list has grown to include 419 children,” Dr. Walsh explains.

The pervasive influence of obesity on both the physical and psychological well-being of children is profound. Dr. Walsh stresses that neither the child nor their family is at fault, pointing to genetic factors and an environment that promotes obesity. “The relentless marketing by food and beverage companies significantly contributes to the problem. Our children are inundated with advertisements daily, pushing fast food, processed items, and oversized portions,” she remarks.

A study presented in Dublin last year offered a glimmer of hope, showing promising results from weekly weight loss injections of semaglutide, a medication under the brand names Wegovy and Ozempic. Nearly half of the children treated no longer met the criteria for clinical obesity following the treatment. However, access to such medications is restricted; adolescents can only use these drugs if they are diabetic or if they can afford private treatment, costing approximately £200 a month.

Dr. Walsh highlights the inequality in access to treatment, especially among socioeconomically disadvantaged adolescents. She contrasts the situation in Ireland with international standards where adolescents have access to weight loss medications and bariatric surgery, which are not readily available in Ireland. Efforts have been made to urge the Health Service Executive (HSE) to provide weight loss medication freely to children suffering from complex obesity. “Treating these adolescents can prevent complications later in life. Investing in adolescent health yields a triple benefit: improving their current and future health, and potentially the health of their future children,” Dr. Walsh advocates.

The paediatrician also runs a general adolescent clinic and sees a troubling trend of obesity-related medical complications such as hypertension, pre-diabetes, and obstructive sleep apnoea, along with significant psychiatric comorbidities. “The stigma, shame, and bullying associated with obesity severely affect their mental health, leading to anxiety, depression, and often undiagnosed eating disorders,” she reveals.

Further stressing the urgency, a 2022 international report indicated that Ireland had the highest rate of risk factors for non-communicable diseases in European adolescents. The study surveyed nearly 500,000 children aged between 11 and 17, revealing that 63% of Irish adolescents exhibited four or more risk factors such as physical inactivity, poor diet, and substance use, compared to just 13% of their Swedish counterparts.

Dr. Walsh reflects on her recent observations in Sweden, where a healthier environment for children starkly contrasts with the situation in Ireland. “Sweden offers extensive support for child health, including widespread access to playgrounds, pools, and government-supported child care, which contributes to a healthier societal setup,” she notes.

The article concludes with the HSE’s response on the current status of obesity treatments under consideration for reimbursement, including medications like Saxenda and Wegovy, which are aimed at adults and potentially extendable to adolescents.

Dr. Walsh’s observations and the data presented underscore a dire need for systemic change to combat adolescent obesity in Ireland, a public health challenge that has only intensified in the wake of the global pandemic.
