What is vitamin B12 deficiency?

Deficiency of any vitamin or nutrient occur when you’re not taking enough of it. Vitamin b12 deficiency is a condition where your daily intake of b12 is less than recommended. This means that you are not including enough b12-rich foods in diet and thus leading to low levels of b12.

Unfortunately, vitamin b12 deficiency is becoming very common, especially in adults. People with strict vegan diet or weight-loss surgery are at major risk of this type of deficiency.

Also there are many other factors that contribute to low levels of b12 such as bowel surgery, some underlying health conditions or medications.

Human body does not produce vitamin b12 by its own. So we need to consume it in daily diet or through supplements. Animal foods and dairy products contains high percentage of b12. However, plant foods don’t have vitamin b12 naturally.

So if you are a vegetarian and not including animal foods, you can start consuming dairy products or vitamin b12 supplements.

weakness and fatigue

If you are feeling overly tired or weak even after having a good night sleep then this could be the warning sign of vitamin b12 deficiency. Weakness, fatigue or lightheadedness are the common symptoms of low b12 levels.

Vitamin b12 plays a role in red blood cells production. Therefore, when your body doesn’t have enough b12, it reduces amount of red cells which are responsible for transporting oxygen to each and every cell of body.

As your body don’t get enough oxygen, you always feel sleepy, tired and exhausted. This is considered as a type of anemia.

A very common form of anemia called “Pernicious anemia” is a most common severe cause of vitamin b12 deficiency. It’s an autoimmune disorder in which important protein called “intrinsic factor” is not produced enough, results into inability to absorb b12.

Many times people confuse this symptom with poor sleep or stress, but if you’re feeling this constant, then it’s a time for you to visit a doctor to treat it early.

2. Numbness and Tingling in hands and feet

Caused by nerve damage, vitamin b12 deficiency leads to pins-and-needles sensations in hands and feet. If you have too many low levels of vitamin b12 then you are more prone to experience numbness and tingling in the hands and feet.

B12 is essential to keep nerve system healthy as it helps to form myelin,which acts as a protective layer to nerve fibers. Without b12, your nervous system won’t be able to work properly.

An untreated long-term vitamin b12 deficiency leads to severe nerve damage and causes paresthesia. You may eventually suffer from other neurological issues such as degeneration of the spinal cord, optic nerves or peripheral nerves.

However, sensations of pins and needles can have many other causes, so better to get tested by your doctor.

Pale or jaundiced skin is another physical condition explaining vitamin b12 deficiency. People with the deficiency of this vitamin are more likely to have pale or yellowish skin and whites of the eyes, which known as jaundice.

This happens when your body lack of healthy red blood cells. Vitamin b12 helps our body to produce healthy red blood cells and lack of it causes a type of anemia called megaloblastic anemia.

Megaloblastic anemia is a condition in which red blood cells become too large and fragile and so unable to divide. They become too large that they cannot pass out of your bone marrow and into blood circulation.

Therefore, your body does not have many healthy cells to circulate around the body which results into pale color of skin.

5. Shortness of Breath and dizziness

One of the possible sign of inadequate amount of b12 is shortness of breath on exertion. Vitamin b12 is responsible in making an essential protein called hemoglobin that transports oxygen throughout the body.

This vitamin deficiency reduces the sufficient oxygen flow to body tissues, causing shortness of breath and dizziness. When the body doesn’t get the enough red blood cells to supply oxygen to each and every cell of the body, you may feel short of breath and a bit dizzy.

Take an immediate visit to your doctor if you experience shortness of breath, unexplained fatigue or heart palpitations.

The reason for this is low level of b12 obstruct brain chemistry that results into imbalance in your neurotransmitters. Especially in elder people, the two – b12 deficiency and dementia are seems to be very common due to age and hard to differentiate.

So if you have no firm reason for your depression or mood swings, then that must be a b12 call.

8. Blurred or disturbed vision

People who are deficient in vitamin b12 may have blurred or disturbed vision. This happens when nervous system damaged due to lack of sufficient b12 amount. This further leads to optic nerve damage.

This damage can disrupt the nervous signal that travels from eye to brain, causing impaired vision.

However, the vision can be often restore by supplements.

9. Swollen, red and smooth tongue

When you don’t take enough vitamin b12, DNA synthesis becomes impaired. As a result, mouth’s epithelial cells begin to divide rapidly, causing glossitis, oral candidiasis, angular cheilitis and recurrent oral ulcers.

There can be many causes for digestive problems such as constipation, gas or diarrhea, and b12 can be one culprit among those. If long-term deficiency is ignored, it triggers gas, constipation, upset stomach and loss of appetite.

Sometimes, people with the deficiency also lack intrinsic factor – a protein in the stomach that allows absorption of vitamin b12. In that case, your body is not able to absorb b12 and the only option is to take vitamin b12 injections.

11. Muscle Weakness

As vitamin b12 plays vital role in the formation of bone-building cells, osteoblasts, lack of it results in losing important bone tissues, causing osteoporosis.

Bones become very weak, fragile or brittle as a result of loss of bone tissues. Because of this, you are more prone to fall or having bone fractures.

Some individuals shows early signs of this “energy vitamin” deficiency such as fatigue, weakness and confusion. But those can be easily misplaced with other causes and actual deficiency get unnoticed.

If the symptoms visible often then it’s time to get an appointment of doctor to stop the effect before the damage becomes irreversible.

Normally, elderly people with 60+ age, those who follow strict vegan diet and undergone of some surgery or taking heartburn medications are at major risk of this vitamin deficiency.
