10 Effects of Vitamin B12 Deficiency
Vitamin B12 makes blood cells, protects nerves, and supplies energy to the body. Unlike most vitamins, vitamin B12 is produced by other organisms and cannot be produced by our body, so it either has to be consumed or obtained in other forms.
Chronic B12 deficiency will cause fatigue. B12 deficiency causes damage to both blood and nerve cells.
The symptoms of B12 deficiency are largely caused by a lack of this vitamin. These can be easy to spot and would ensure that the deficiency is easily corrected. A blood test is a simple objective way to analyze anyone’s vitamin B12 levels. Once this has been done, the cause of the deficiency can be corrected. Some of the contributory factors of the deficiency are discussed in this article, and some general advice is given for the symptomatic sufferers.
Quick Overview
Section 1: Vitamin B12
Unlike most vitamins, some have to come from other organisms and are therefore consumed. Fatigue is an overarching problem caused by several symptoms of vitamin B12 deficiency, and our Fatigue Guide has more information regarding this.
Section 2: Importance of Vitamin B12
Vitamin B12 helps with the healthy functioning of the blood, nerves, and brain.
Section 3: Diagnosing Vitamin B12 Deficiency
Confused with general exhaustion, the following signs and symptoms of vitamin B12 deficiency progress slowly.
Section 4: Vitamin B12 and Its Role
Low absorption, illness, and diet are a few of the reasons associated with the increased risk of a vitamin B12 deficiency.
Section 5: High-risk Groups for Vitamin B12 Deficiency
Of the many risk groups, vegans and older people are at the highest risk of developing a vitamin B12 deficiency.
Section 6: Determining Potential Vitamin B12 Deficiency
Blood tests are the only way of identifying a vitamin B12 deficiency.
The possible symptoms lead patients to suspect that they may be vitamin B12 deficient, such as:
- Tiredness
- Elderly
- Other health problems
- Importance of Vitamin B12
Vitamin B12 affects the blood, brain, nerves, mood, and energy levels.
7. Additionally, B12 deficiency can cause dizziness and lightheadedness; navigate to our article on dizziness for more information.
8. A sore and swollen mouth and tongue, and mouth and throat sores are a few more signs and symptoms of B12 deficiency.
9. B12 deficiency may even cause clouded thought and the inability to think clearly and remember.
10. More irritability and low moods may be caused by B12 deficiency as well.Severe B12 deficiency can eventually cause an inability to walk due to neurological imbalance.
Your symptoms could have many possible explanations. Long-term symptoms may be indicative of a B12 deficiency and are a serious concern that should not be ignored.
B12 Deficiency
B12 deficiency currently has no known incidence of real-world cases and thus can be broken into two sections.
Diet-Based
Vegans and some vegetarians have the highest risk of B12 deficiency. This is easy to address with the modification of food or the use of supplements.
Absorption-Based
Healthy individuals don’t have problems absorbing B12. B12 absorption issues, however, can be caused by various gastrointestinal issues, medical conditions, or surgical issues.
Advanced age is a risk factor for B12 deficiency.
For many surgical or medical conditions, B12 levels can be altered. The course of treatment in this case is dependent on the underlying issue.
- These issues can be explained by your doctor.
- What are the high-risk populations?
- The following individuals have a greater risk for B12 deficiency:
- People 60 years old or older
- People who eat only plants and no meat
- People who have had all or part of their stomach removed and have trouble absorbing vitamin B-12
- Individuals who are on long-term medications
These individuals should have their B12 levels checked more frequently. These populations should also take daily supplements if they do not meet B12 dietary requirements through food.
Diagnosis of Vitamin B12 Deficiency
Vitamin B12 deficiency can only be diagnosed with blood tests. Blood will be taken to check the levels of B12. That is the only way to diagnose anemia.
When a doctor notices the early signs of vitamin B12 deficiency, they do not consider other causes and order a B12 blood test. This is the only way to confirm that the diagnosis is vitamin B12 deficiency and that there is a vitamin deficiency in the first place.
No medical attention for B12 deficiency is very irresponsible and carries serious risks. The symptoms worsen and become problems. The symptoms of vitamin B12 deficiency are best treated by eliminating the reason for the deficiency.
We differentiate between a deficiency caused by a poor diet or poor absorption. A deficiency of vitamin B12 is treated by giving vitamin B12 supplements and eating foods that contain added vitamin B12.
If the cause is poor absorption, oral vitamin B12 will not fix it, so most doctors prefer to give vitamin B12 in other ways, for example, by injections.
We will address each situation individually. Absorption deficiencies are chronic and usually will be a lifelong condition. It is very important to discover this condition early and start treatment as soon as possible because the effects caused by the deficiency can never be reversed.
Treatment for deficiency will not commence until a cause is known.
Food Containing Vitamin B12:
Vitamin B12 can be found in foods like meat, fortified breakfast cereals, and milk substitutes, as well as in milk and cheese.
If you do not eat meat, you will have to find sources for your B12.
As expected, fruits and vegetables are not good sources of B12, and vegans and vegetarians consume B12 in fortified foods and/or take vitamin B12 supplements.
B12 and Anemia
The symptoms of anemia and vitamin B12 deficiency overlap, and in order to understand the causes and symptoms of vitamin B12 deficiency, we will look into anemia and B12.
Vitamin B12 is needed for the growth of blood cells. When vitamin B12 is missing, the body cannot make new red blood cells, and anemia comes about. The signs of anemia and the lack of vitamin B12 are fatigue, weakness, feeling tired, breathlessness, and low energy.
Other causes of anemia result in fatigue and feeling weak. Because of the overlapping symptoms of anemia and a vitamin B12 deficiency, you should read our article on iron deficiency anemia. Distinguishing the two can be nearly impossible, so getting a blood test is always recommended.
Neurological signs are the most important.
The importance of the symptoms of B12 deficiency is reversed when we deal with the symptoms. The serious symptoms of B12 deficiency are neurological.
Vitamin B12 deficiency causes nerve atrophy. There is a feeling of numbness in the arms and legs. If B12 levels continue to decrease, people lose the ability to walk and experience poor balance. With the B12 deficiency corrected, all the neurological symptoms reverse. There is a gap in the healing of blood diseases. There is a disconnect in the healing of blood diseases and the most common healing symptoms of blood diseases.
The symptoms described above are permanent. Please consult your doctor before it’s too late.
Permanent nerve damage is something to take very seriously, so take no chances with self-treating or self-diagnosing. There will come a time when there will be no permanent signs of nerve damage.
If you have tiredness, numbness, weakness, poor balance, or trouble with coordination, you should see your doctor. If you have pain, numbness, or a tingling feeling in your hands, legs, or feet, you need to visit your doctor. So do pain, numbness, tingling, and balance issues with difficulty walking.
Consult your doctor if the following describe you:
- You experience two or more symptoms of a B12 deficiency
- There are signs of impaired normal functioning of your body
- You are having difficulty deciding whether you should have the test or take a B12 supplement
- The symptoms of B12 deficiency continue to deteriorate if you do not intervene.
Blood tests are used to confirm B12 deficiency, and getting a blood draw is the most convenient. Symptoms will worsen if you leave the deficiency untreated. The NHS covers the symptoms of B12 deficiency; just click the link.
Most adults are likely to have mild symptoms of B12 deficiency. B12 deficiency symptoms are so mild that most people do not experience symptoms associated with B12 deficiencies. Because of the symptoms, many people are reluctant to get tested. However, B12 deficiency symptoms are usually temporary. Healing usually starts when you start taking B12 supplements. B12 deficiency is a chronic condition; fortunately, healing it is quite easy. Most people can choose to take B12 supplements or change their diets to include foods that are fortified with B12.

This post is only for informational purposes. Please consult a professional for a proper diagnosis and treatment. Especially for symptoms of numbness/tingling, particularly of the extremities, as these can be symptoms of more serious conditions and be debilitating.

Do you think the people you and I know are at more risk for B12 deficiency? Who do you think is at most risk? Definitely those are vegan people. But also older people, people who have surgeries, certain medications, etc.
Does fatigue mean you have B12 deficiency?
Yes, fatigue is definitely a sign of B12 deficiency. Low B12 levels can cause fatigue. However, fatigue certainly can be caused by many other things, which is why a blood test is the only way to confirm.
Can vegans have healthy levels of B12?
As B12 is an animal-derived product, surely vegans must take B12 supplements. Lucky enough, reliable and trustworthy sources of B12 supplements exist, allowing vegans to gain sufficient amounts of B12.
Why does B12 deficiency concern us?
If B12 deficiency is not treated, it can lead to permanent and disastrous effects in the nervous system and can lead to nervous system problems like loss of control of movements, loss of balance, numbness and tingling in the limbs, etc. Most of the effects of B12 deficiency are long-lasting and can be very damaging, as can the effects of the deficiency itself, which can progress quickly.
How do we diagnose B12 deficiency?
Blood samples are taken, and the concentration of B12 in the blood is checked along with the general health of the blood. A doctor decides whether a patient has a B12 deficiency based on lab reports. The doctor then orders other tests to check for the different causes of the B12 deficiency. Here, a diagnosis is required to be complete, along with some sort of explanation.
