PTSD Remission Aids Diabetes Control
Veterans with PTSD who no longer meet diagnostic criteria show reduced risks of hyperglycaemia and related complications, per a recent JAMA Network Open study on over 76,000 patients.
A recent study has highlighted the interplay between post-traumatic stress disorder (PTSD) and type 2 diabetes (T2D), finding that remission of PTSD symptoms significantly improves diabetes management outcomes among veterans(1). Published in JAMA Network Open on 1 August 2024, the research analysed electronic health records from 76,190 US veterans with T2D, of whom 11,464 also had PTSD. Over a mean follow-up of 6.7 years, those whose PTSD remitted – no longer meeting diagnostic criteria – showed a 21% lower risk of hyperglycaemia episodes, alongside reduced odds of acute T2D complications like hypoglycaemia and diabetic ketoacidosis(1).
This bidirectional relationship aligns with accumulating evidence that chronic stress from PTSD disrupts metabolic regulation, exacerbating insulin resistance and glycaemic instability. The National Institute of Mental Health notes PTSD often co-occurs with conditions like diabetes due to shared neurobiological pathways involving heightened inflammation and hypothalamic-pituitary-adrenal axis dysregulation. In Australia, where veteran PTSD prevalence mirrors global rates around 10-20%, such comorbidities pose substantial health burdens.
Experts emphasise PTSD’s treatability as a modifiable risk factor. Trauma-focused therapies, such as prolonged exposure or cognitive processing therapy, can achieve remission rates of 40-60% in responsive patients. A Cochrane review updated in August 2024 found repetitive transcranial magnetic stimulation (rTMS) promising for PTSD symptom reduction, though evidence quality remains low. Australian clinicians, including those via Department of Veterans’ Affairs programs, increasingly integrate such interventions.
Comorbidities extend beyond diabetes. PTSD heightens risks for sleep disturbances, which longitudinal data link to symptom persistence; subjective poor sleep predicts worsening PTSD over four years. Healthcare workers exposed to mass casualty events report elevated PTSD alongside anxiety and depression. An individual participant data meta-analysis involving Australian researcher Dr Charles Lee supports eye movement desensitisation and reprocessing (EMDR) as comparable to other psychotherapies for PTSD.
For Australians living with PTSD and T2D, holistic care is key. Mayo Clinic outlines screening for both conditions, advocating multidisciplinary approaches combining psychotherapy, medication and lifestyle interventions. Remission not only alleviates psychological distress but enhances physical resilience, offering hope for better long-term health.
