Young, stressed and struggling: Why SA’s mental health crisis is getting worse

Mental health conditions among young South Africans have surged by 80% in a decade, new data shows. But experts say the rise is as much a sign of progress as it is a warning. According to the HealthTrend2026 report released by Discovery Health, the largest analysis of its kind in South Africa, which draws on more than 60 million life-years of clinical and behavioural data.

The report said the prevalence of mental health conditions among members aged 18 to 30 has increased by 80% over the past decade. In 2015, one in twelve young adults was claiming a mental health condition. The HealthTrend2026 Report covers more than 2.7 million members.

The report was presented at a media briefing in Johannesburg on 10 June 2026. Discovery Health CEO Dr Ron Whelan was unambiguous about the scale of the shift. “This is one of the most important changes we are seeing in the data,” he told guests at the report’s launch in Sandton.

“More members, especially younger adults, are seeking help earlier. That is a positive shift. When mental health is identified and supported alongside physical health, outcomes improve, and avoidable escalation is reduced.” Crucially, the increase in prevalence has not been matched by an increase in severity.

Hospital admission rates for mental health conditions actually declined by 11% over the same ten-year period, a finding the report describes as a clear indicator that earlier intervention is working. Depression remains the dominant diagnosis, accounting for 63% of mental health claims across the scheme. Dr Noluthando Nematswerani, chief clinical officer at Discovery Health, elaborated on what the data is revealing.

“What we’re seeing is that there is more utilisation of out-of-hospital benefits, which is why you actually would like to see maybe a bit of a reduction in hospitalisation,” she said. The shift toward outpatient psychological care and community-based support, she argued, is exactly the trajectory the system should pursue. One of the more striking findings in the report is the degree to which mental health conditions interact with other chronic diseases, dramatically amplifying both healthcare costs and hospitalisation risk.
