The condition develops when the median nerve is strained, the nerve and tendons swell, or something triggers inflammation in the carpal tunnel. This narrow passage connecting wrist to hand contains bones, ligaments, and tendons that can compress the nerve responsible for sensation in the thumb and first two fingers.
How Do You Get Carpal Tunnel?
Pregnancy
During pregnancy, blood volume and fluid double, and hormones retain this excess fluid. This causes swelling that may compress the median nerve, resulting in numbness and tingling.
Wrist Injuries
Fractures or dislocations reduce carpal tunnel space, increasing pressure on the median nerve and triggering symptoms.
Arthritis
Rheumatoid arthritis and similar conditions cause joint swelling and inflammation that can precipitate carpal tunnel syndrome.
Overuse Damage
Repetitive hand movements and awkward arm postures irritate and inflame tendons, injuring the hand.
Congenital Factors
Some people naturally have narrower carpal tunnels. The condition is more prevalent in women because carpal tunnels are relatively smaller or narrower in females than males.
Are You at Risk for Carpal Tunnel Syndrome?
Risk factors include being a woman aged 40-60, pregnancy, rapid weight gain, repetitive hand use, and diagnosed arthritis.
