What vitamin deficiency causes peripheral neuritis?

Peripheral neuritis may be caused by deficiencies in vitamins such as vitamin B1, vitamin B6, vitamin B12, vitamin E, and folic acid. If symptoms such as numbness or pain occur, it is recommended to seek medical attention promptly to prevent the condition from worsening due to delayed treatment. Detailed analysis is as follows:

1. Vitamin B1: Plays an essential role in maintaining normal nervous system function and participates in energy metabolism and nerve conduction. A deficiency of vitamin B1 in the body may lead to peripheral neuritis, manifesting as sensory abnormalities in the distal extremities, such as numbness and pain.

2. Vitamin B6: Plays a crucial role in the synthesis of neurotransmitters and helps maintain normal nervous system function. A deficiency in vitamin B6 may result in neurological abnormalities, leading to peripheral neuritis.

3. Vitamin B12: Involved in the growth and maintenance of nerve cells, helping preserve nervous system function. A deficiency in vitamin B12 may cause nerve damage, thereby triggering peripheral neuritis.

4. Vitamin E: Acts as an antioxidant that protects the nervous system from oxidative stress. A deficiency in vitamin E may make nerve endings more susceptible to damage, resulting in peripheral neuritis.

5. Folic acid: A member of the vitamin B complex, it is important for DNA synthesis and repair and contributes to maintaining nervous system function. A deficiency in folic acid may lead to neurological abnormalities, causing patients to develop peripheral neuritis.

If diagnosed with peripheral neuritis, it is recommended to follow medical advice and use medications such as mecobalamin capsules, acetaminophen tablets, and carbamazepine tablets. Food cannot replace the therapeutic effects of medication. In daily life, patients are advised to maintain a balanced diet, avoid picky eating, and ensure adequate sleep, all of which are beneficial for recovery.
