Why Low Vitamin B12 Levels Are Common In Older Adults
To understand how low vitamin B12 levels happen in aging adults, its good to start by learning how the body usually obtains and processes this vitamin.
In nature, vitamin B12 is available to humans only in meat and dairy products. However, in modern times, you can easily get it via a supplement or multivitamin. The recommended daily allowance for vitamin B12 for adults is 2.4 micrograms. Experts have estimated that a Western diet contains 5-7 micrograms of vitamin B12, and a multivitamin often contains 12-25 micrograms.
Once you ingest vitamin B12, it is processed by acids and enzymes in the stomach and small intestine. The processed vitamin is then absorbed by the small intestine and stored in the body, especially in the liver.
This stash can actually meet the bodys needs for a few years although vitamin B12 is essential, only a tiny bit is needed every day. So if a healthy person stops taking in vitamin B12, it often takes a few years before the body runs out of it and develops symptoms.
So why does vitamin B12 deficiency particularly affect older adults?
As people get older, their ability to absorb vitamin B12 decreases. This is because aging adults often develop problems with the acids and stomach enzymes needed to process the vitamin.
Common risk factors for low vitamin B12 levels in older adults include:
· Low levels of stomach acid. This can be due to weakening of the stomach lining, or to medications that reduce stomach acid.

Ruling Out Folate Deficiency
A deficiency of folate, the nutrient also known as folic acid or vitamin B9, good sources of which include foods like broccoli, asparagus, peas and brown rice, can cause some of the same symptoms as vitamin B12 deficiency. For this reason, a doctor will typically examine the levels of folate in blood tests when checking for vitamin B12 deficiency.
Taking a lot of folic acid can mask the symptoms of a vitamin B12 deficiency, so in cases where folate deficiency is suspected, a doctor will usually test for vitamin B12 deficiency before prescribing medication.
Drawbacks Of Blood Tests For Vitamin B12 Deficiency
Some people experience symptoms of vitamin B12 deficiency despite their blood tests indicating normal levels. The test measures the total amount of the vitamin in the blood, but not all of it can necessarily be used by the body. In addition, the range of normal levels may differ between laboratories.
For these reasons, healthcare practitioners will usually consider signs and symptoms, as well as the results of the blood tests when diagnosing vitamin B12 deficiency.

Treatment Of Vitamin B12 Deficiency
Treatment will depend on the reasons for the vitamin B12 deficiency. In most cases, having injections or taking a prescribed oral supplement will be sufficient to treat the condition.
A doctor may recommend having high-dose injections of vitamin B12, usually in a form called hydroxocobalamin, every second day for two weeks, or until symptoms have cleared.
If the cause of the deficiency is dietary, the doctor may advise taking a daily supplement or continuing to have injections twice a year or more, indefinitely. They may also refer the person to a dietician for advice on ways to increase vitamin B12 intake in their diet.
In cases where the deficiency is not related to a personâs diet, it will usually be necessary to have vitamin B12 injections every three months or more frequently, for the rest of their life.
People who have symptoms that affect their nervous system, such as pins and needles or numbness, may be referred to a hematologist for specialized management of the deficiency. It may be necessary for them to have injections every two months or more frequently, for life.
Vitamin B12 injections typically do not have any side-effects other than a small amount of discomfort where the needle is inserted.
Follow-up blood tests will generally be requested one to three months after starting treatment, to check that vitamin B12 levels have returned to normal. Thereafter, a doctor may advise a once-yearly follow-up test.
Why Vitamin B12 Deficiency Is Often Missed In Aging Adults
Vitamin B12 deficiency is often missed because the symptoms fatigue, anemia, neuropathy, memory problems, or walking difficulties are quite common in older adults, and can easily be caused by something else.
Also, vitamin B12 deficiency tends to come on very slowly, so people often go through a long period of being mildly deficient. During this time, an older person might have barely noticeable symptoms, or the symptoms might be attributed to another chronic health condition.
Still, a mild deficiency will almost always get worse over time. And even when an older adult has many other causes for fatigue or problems with mobility, its good to fix whatever aggravating factors such as a vitamin deficiency can be fixed.
Unlike many problems that affect aging adults, vitamin B12 deficiency is quite treatable. Detection is the key then make sure the treatment plan has raised the vitamin B12 levels and kept them steady.
