सोते समय हाथों में सुन्नपन किस कमी के कारण होता है?

Numbness in the hands while sleeping can be frustrating, and while vitamin deficiencies might play a role, there’s a broader range of possible causes to consider. Vitamin B12 deficiency is indeed one deficiency that can contribute to nerve issues, potentially causing numbness in the hands. However, since you’ve mentioned having bloodwork done without any indication of vitamin issues, it might be less likely to be the root cause here unless they specifcially tested for it. Another aspect to examine is your sleeping position. You mentioned sleeping on your side, which can compress nerves like the ulnar nerve at the elbow or wrist, causing that tingling sensation. This is sometimes referred to as “entrapment neuropathy” and can occur if you sleep with your arms at awkward angles. Carpal tunnel syndrome is another possibility, where pressure on the median nerve at the wrist can lead to such numbness, although this typically affects the thumb, index, middle, and part of the ring finger. It might be useful to wear a wrist splint to keep your wrists in a neutral position at night. You could also try changing your sleeping positions to see if that alleviates the numbness. If these adjustments don’t seem to help, or if the numbness becomes more frequent or severe, you should consult a healthcare provider. They might suggest tests like nerve conduction studies to check for carpal tunnel or other neuropathic conditions. If you suspect a vitamin deficiency despite your past tests, you could discuss the possibility of targeted supplementation with your doctor. Rather than assuming it’s purely a deficiency, a more comprehensive approach that considers a range of factors (including your posture, ergonomic aspects, and lifestyle) might be needed.
