Vitamin B12 Deficiency
WHAT YOU NEED TO KNOW:
Vitamin B12 deficiency is a low level of vitamin B12 in your body. Vitamin B12 is only found in foods that come from animal sources such as fish, beef, dairy products, and eggs. Vitamin B12 deficiency should be treated as early as possible. Without treatment, it can cause permanent nerve damage over time.
- Vitamin B12 supplements may be needed to increase your levels back to normal.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
