What is Vitamin B12 Deficiency?
Vitamin B12 deficiency happens when your body does not get enough vitamin B12. This vitamin helps keep your nerves and blood cells healthy. Without enough B12, your body cannot make red blood cells well. As a result, you may feel tired or weak. Over time, low B12 can also harm your nerves. According to the World Health Organization, vitamin B12 deficiency is common, especially in older adults and people with certain diets.
How Does Vitamin B12 Deficiency Cause Neuropathy?
Neuropathy means nerve damage. When you lack vitamin B12, your nerves cannot work as they should. For example, B12 helps make a coating called myelin. Myelin protects your nerves and helps messages travel quickly. Without enough B12, myelin breaks down. Because of this, your nerves may get damaged. Over time, you may notice numbness, tingling, or weakness. Treating vitamin B12 deficiency early can help prevent nerve damage from B12 deficiency.

Diagnosis and Medical Evaluation
If you have symptoms, your doctor will ask about your health and diet. Next, they may order blood tests to check your B12 level. Sometimes, more tests are needed to see if your nerves are affected. For example, nerve tests can show if you have neuropathy. Early diagnosis is important. That way, you can start treating vitamin B12 deficiency before nerve damage becomes severe.
Treatment Options
Treating vitamin B12 deficiency is often simple. Most people need to take B12 supplements. These can be pills, shots, or nasal sprays. Your doctor will choose the best option for you. In some cases, you may need lifelong treatment. Along with supplements, eating foods rich in B12 can help. For example, good sources include:
