Why Women Experience Higher Rates of Chronic Pain than Men
March 19, 2025

A study led by Dr. Tuan Trang at the University of Calgary explores why chronic pain is more prevalent in women than men. Chronic pain, notably more common in females, is often challenging to treat. Published in Neuron, the research examines neuropathic pain stemming from nerve injuries, which can cause allodynia—a condition where non-painful stimuli become painful. The study reveals that pain signals in male and female rodents are communicated through pannexin 1 (Panx1) channels but involve different immune cell processes. In females, Panx1 activation releases leptin, a hormone linked to increased pain sensitivity. This discovery builds on past findings of elevated leptin levels in women with chronic pain. Dr. Lori Montgomery emphasizes the significance of this research in understanding sex differences in pain, paving the way for personalized treatments that consider these factors, potentially improving treatment efficacy for women suffering from chronic pain.
