So carpal tunnel's when there's compression of the median nerve here in your wrist, which is where the carpal tunnel is.

腕管是指手腕正中神经受压，腕管就在这里。

Other risk factors of carpal tunnel syndrome include obesity or pregnancy, as well as having underlying conditions like rheumatoid arthritis where there's joint inflammation from an autoimmune process, that leads to the compression of the median nerve.

腕管综合征的其他危险因素还包括肥胖和怀孕，和一些潜在的症状如类风湿性关节炎（一种由免疫反应导致的关节炎症，也会引起正中神经卡压）。
