Vitamin B12 deficiency symptoms: The sign in your chest you could be lacking B12

Vitamin B12 may be lacking from your body if you’re experiencing one heart racing symptom. And it’s not the only problem you’ll encounter if you don’t treat the underlying cause.

Foods rich in vitamin B12 include cheese, salmon, eggs and meat.

However, you may be unable to absorb the nutrient in your gut – this condition is called pernicious anaemia.

Or, as the NHS added, it may be the result of taking certain medication.

To be more specific, anticonvulsants and proton pump inhibitors (PPIs) can affect how much your body absorbs vitamin B12.

Perhaps it’s due to advancing age. The NHS stated: “It becomes more difficult to absorb vitamin B12 as you get older.”

In fact, the national health body suspects “one in 10 people aged 75 or over” will have a vitamin B12 deficiency.

So, how can you tell if you’re lacking in the vital nutrient or not?

According to the Mayo Clinic, an irregular heartbeat is a symptom of a vitamin B12 deficiency.

The NHS define an irregular heartbeat as an arrhythmia – the most common being atrial fibrillation (AF).

AF is more common in older adults, and it can be attributed to drinking too much alcohol or being overweight.

You’re also at risk of developing AF if you’ve previously had a heart attack or suffer from heart failure.

Experiencing AF increases a person’s risk of having a stroke by five times – so it’s certainly a condition to keep an eye on.

Triggers for an irregular heartbeat include viral illnesses, alcohol, tobacco, exercise, caffeine and changes in posture.

An irregular heart beat is the result of an abnormality of the heart’s rhythm.

But what about the vitamin B12 deficiency? Are there other signs you’re struggling to get the nutrients you need?

Yes, the Mayo Clinic outlines other symptoms you may experience if you’re deficient in vitamin B12.

For example, some people may feel fatigued and could feel numbness or tingling in their hands and feet.

Other symptoms may involve muscle weakness, weight loss and pale or yellowish skin.

Furthermore, dizziness may be a factor, as well as shortness of breath and unsteady movements.

It can take years for a vitamin B12 deficiency to become apparent.

This is especially true as symptoms may be subtle at first, but then increase as the deficiency worsens.

Different blood tests can establish whether you have a vitamin B12 deficiency.

The NHS concluded that even low amounts of vitamin B12 in the body may not appear as symptoms, and so a blood test is the best call of action.
