Vitamin B12 is essential for the proper functioning of the nervous system. When levels of B12 are low, nerve cells can't properly function, leading to neuropathy.
The deficiency leads to a decrease in the synthesis of myelin, the protective coating on nerve cells. This results in slower nerve conduction and can cause symptoms such as tingling, numbness, and weakness in the hands and feet.
B12 deficiency can also lead to the accumulation of homocysteine, an amino acid that can cause damage to the blood vessels that supply the nerves. This can lead to ischemia and further nerve damage.
Since B12 break down homocysteine
High homocysteine levels may mean you have a VD

In addition to the peripheral neuropathy, B12 deficiency can also lead to damage to the spinal cord and brain, resulting in cognitive and psychiatric symptoms.
The deficiency is most common in older adults, vegetarians and vegans, and people with intestinal disorders that affect absorption.
The first step in diagnosing neuropathy caused by B12 deficiency is a thorough medical history and physical examination. Your healthcare provider may also order blood tests to check your B12 levels.
also order additional tests such as a methylmalonic acid (MMA) test or homocysteine test to confirm the diagnosis.
treatment will typically involve supplementation with B12. This can be in the form of oral supplements, intramuscular injections, or sublingual tablets.

The dosage and frequency of B12 supplements will depend on the severity of the deficiency and the individual's needs.
in addition to supplementation,it's important to address any underlying causes of B12 deficiency, such as a dietary deficiency or an underlying medical condition

In summary, B12 deficiency leads to damage to the protective coating of nerve cells and blood vessels, resulting in neuropathy, cognitive and psychiatric symptoms. It's important to detect and treat the deficiency early to prevent further damage.
