Carpal Tunnel Syndrome and Obesity
Carpal tunnel syndrome — numbness and tingling in the hand caused by pressure on a wrist nerve — occurs more often in people with obesity.
Plain English
Patient-Friendly Explanation
Carpal tunnel syndrome — numbness and tingling in the hand caused by pressure on a wrist nerve — occurs more often in people with obesity. The condition happens when the median nerve in the wrist is compressed. Obesity raises the risk, and losing weight can help relieve symptoms.
Medical
Clinical Definition
Carpal tunnel syndrome (CTS) is a compression neuropathy of the median nerve at the wrist, and obesity is an established risk factor: higher BMI is associated with increased pressure within the carpal tunnel, and obesity frequently coexists with diabetes and hypothyroidism, which also predispose to CTS. Cohort studies demonstrate a dose–response relationship between body mass index and CTS incidence, and outcomes after carpal tunnel release are generally less favourable in individuals with higher body weight. Weight reduction is therefore recommended as part of conservative management alongside wrist splinting and activity modification.
Key Insight
Why It Matters
Recurrent hand numbness or tingling at night should not be dismissed as a minor nuisance. Recognising nerve compression problems such as carpal tunnel syndrome is part of the thorough assessment we offer patients with excess weight.
