New research reveals that brief corticosteroid treatments, commonly used to manage asthma and allergies, are linked to heightened risks of complications including fractures, gastrointestinal bleeding, and heart failure in adults with type 2 diabetes, prompting calls for more cautious use.
Short courses of oral corticosteroids, often used to quickly calm asthma and allergy flare-ups, may carry more risk for adults with type 2 diabetes than previously appreciated. A study published in JAMA Network Open found that these brief steroid bursts were linked not only to the expected rise in blood sugar, but also to higher odds of serious complications in the weeks after treatment began.
The researchers analysed health records from Taiwan’s National Health Insurance Research Database and identified 36,048 adults with type 2 diabetes who had received oral corticosteroid bursts. Using a self-controlled case series design, in which each patient acted as their own comparison, they examined the period shortly after treatment against times when the same patients were not taking steroids. According to the study, the risk of gastrointestinal bleeding, pneumonia and heart failure rose sharply in the first 6 to 30 days after treatment started.
The elevated risk did not disappear immediately once the course ended. JAMA Network Open reported that some harms remained measurable between 31 and 90 days after exposure, including a continued increase in fractures. The study found fracture risk was still 1.42 times higher than baseline in that later window, while gastrointestinal bleeding also remained above normal. An earlier review in NEJM Clinician similarly noted increased risks of gastrointestinal bleeding, pneumonia and sepsis in the days after short steroid bursts, reinforcing the concern that even brief treatment can have effects beyond temporary hyperglycaemia.
The findings do not suggest that corticosteroids should be avoided outright. They remain important medicines for acute inflammatory conditions, and the authors said their results should be read as a prompt for more careful weighing of benefits and risks in people with diabetes. But the study adds to a growing body of evidence that short oral steroid courses deserve closer scrutiny in a population already vulnerable to infection, cardiovascular problems and fractures.
