The Link Between Vitamin B12 Deficiency and Shortness of Breath

Vitamin B12 deficiency can indeed cause shortness of breath, but this symptom is typically a result of anemia that develops due to low B12 levels. When the body lacks sufficient vitamin B12, it cannot produce enough healthy red blood cells, leading to a condition called megaloblastic anemia. This type of anemia affects the body’s ability to transport oxygen effectively, resulting in breathlessness and fatigue.

Is shortness of breath always a sign of B12 deficiency. While it can be a symptom, it’s important to note that many other conditions can also cause breathlessness. If you’re experiencing persistent shortness of breath, it’s crucial to consult a healthcare professional for proper diagnosis and treatment.

Common Symptoms of Vitamin B12 Deficiency

Vitamin B12 deficiency can manifest in various ways, affecting multiple body systems. Some of the most common symptoms include:

Fatigue and weakness
Constipation
Loss of appetite and weight loss
Balance problems
Depression
Cognitive issues
Sore mouth or tongue

In infants, B12 deficiency can lead to developmental delays and movement problems. It’s crucial to recognize these symptoms early, as untreated B12 deficiency can result in long-term health complications.

Anemia-Related Symptoms

Anemia caused by B12 deficiency can lead to additional symptoms, including:

Shortness of breath
Feeling faint
Headaches
Pale or yellowish skin
Heart palpitations
Tinnitus (ringing in the ears)

Do these symptoms always indicate B12 deficiency anemia. While these symptoms are common in B12 deficiency anemia, they can also be present in other types of anemia or health conditions. A proper medical evaluation is necessary for accurate diagnosis.

Neurological Impact of Vitamin B12 Deficiency

Vitamin B12 plays a crucial role in maintaining a healthy nervous system. A deficiency can lead to various neurological symptoms, including:

Numbness and tingling in hands and feet
Cognitive impairment
Confusion
Balance issues
Changes in gait and movement

Can B12 deficiency cause permanent neurological damage. If left untreated for an extended period, B12 deficiency can indeed lead to irreversible nerve damage. This underscores the importance of early detection and treatment.

Long-Term Health Risks Associated with B12 Deficiency

Chronic vitamin B12 deficiency can increase the risk of several health problems. One key factor is the body’s inability to process homocysteine effectively when B12 levels are low. High homocysteine levels have been linked to various health conditions, including:

Dementia
Cardiovascular disease
Cognitive decline
Depression

Research has shown that individuals with Alzheimer’s disease and dementia often have higher levels of homocysteine. A study involving 121 people aged 65 and over found that those with stronger signs of B12 deficiency at the start of the study were more likely to have lower cognitive test scores and smaller brain volumes after 52 months.

Neurological Damage and Cardiovascular Risk

Studies have revealed that 20-30% of people with B12 deficiency experience neurological damage, which can affect the nerves, spinal cord, and mental health. Additionally, high homocysteine levels have been observed in individuals with coronary heart disease and stroke. However, more research is needed to determine if B12 supplementation can prevent heart disease.

Recommended Daily Intake of Vitamin B12

The amount of vitamin B12 a person needs daily varies based on age, with increased requirements during pregnancy and breastfeeding. According to the Office of Dietary Supplements (ODS), the average daily recommended amounts are:

0-6 months: 0.4 mcg
7-12 months: 0.5 mcg
1-3 years: 0.9 mcg
4-8 years: 1.2 mcg
9-13 years: 1.8 mcg
14 years and over: 2.4 mcg
During pregnancy: 2.6 mcg
While breastfeeding: 2.8 mcg

Are these recommendations sufficient for everyone. While these guidelines are appropriate for most people, individuals with certain health conditions or those following specific diets may require higher doses. It’s best to consult with a healthcare provider to determine your personal B12 needs.

Causes and Risk Factors for B12 Deficiency

Vitamin B12 deficiency can occur due to inadequate dietary intake or problems with absorption during digestion. Some common causes and risk factors include:

Strict vegetarian or vegan diets
Pernicious anemia (an autoimmune condition affecting B12 absorption)
Gastrointestinal disorders (e.g., Crohn’s disease, celiac disease)
Certain medications (e.g., proton pump inhibitors, metformin)
Gastric bypass surgery
Advanced age

Can medications interfere with B12 absorption. Yes, certain medications can affect B12 absorption. If you’re taking long-term medication, especially for acid reflux or diabetes, discuss potential B12 deficiency risks with your healthcare provider.

The Process of Vitamin B12 Absorption

The absorption of vitamin B12 from food is a complex process that involves several steps:

Hydrochloric acid in the stomach separates B12 from the protein it’s bound to in food.
B12 combines with a protein called intrinsic factor, which is produced by the stomach.
The B12-intrinsic factor complex is then absorbed in the small intestine.

Why is intrinsic factor important for B12 absorption. Intrinsic factor is crucial because it allows the body to absorb vitamin B12 efficiently. Without sufficient intrinsic factor, as in the case of pernicious anemia, B12 deficiency can occur even if dietary intake is adequate.

Diagnosis and Treatment of Vitamin B12 Deficiency

Diagnosing B12 deficiency typically involves blood tests to measure B12 levels and assess for anemia. Treatment options may include:

Oral B12 supplements
B12 injections
Dietary changes to increase B12 intake
Addressing underlying conditions affecting B12 absorption

How long does it take to correct a B12 deficiency. The time to correct a B12 deficiency varies depending on the severity and the treatment method. Some people may experience improvement in symptoms within days or weeks of starting treatment, while others may take several months to fully recover.

Prevention Strategies

Preventing B12 deficiency involves ensuring adequate dietary intake or supplementation when necessary. Good food sources of vitamin B12 include:

Meat, poultry, and fish
Eggs and dairy products
Fortified cereals and plant-based milk alternatives
Nutritional yeast

Individuals following plant-based diets or those with absorption issues may need to consider B12 supplements or fortified foods to meet their needs.

Can B12 supplements improve energy levels in people without deficiency. While B12 supplements are often marketed as energy boosters, research suggests they only improve energy levels in individuals with a pre-existing deficiency. For those with adequate B12 levels, additional supplementation is unlikely to provide significant energy benefits.

Monitoring and Long-term Management

For individuals diagnosed with B12 deficiency, ongoing monitoring and management are essential. This may involve:

Regular blood tests to check B12 levels
Adjusting supplement dosages as needed
Addressing any underlying health conditions
Lifestyle modifications to support overall health

How often should B12 levels be checked in at-risk individuals. The frequency of B12 level checks depends on individual risk factors and treatment plans. Some people may need testing every few months, while others may require annual checks. Your healthcare provider can recommend an appropriate monitoring schedule based on your specific situation.

Special Considerations for Different Population Groups

Certain groups may have unique considerations when it comes to B12 deficiency:

Older Adults

As people age, their ability to absorb vitamin B12 from food often decreases. This is due to reduced stomach acid production and other age-related factors. Older adults may benefit from B12 supplements or fortified foods to maintain adequate levels.

Pregnant and Breastfeeding Women

Adequate B12 intake is crucial during pregnancy and breastfeeding to support fetal development and infant health. Pregnant and breastfeeding women have higher B12 requirements and may need supplementation, especially if following a plant-based diet.

Vegetarians and Vegans

Since vitamin B12 is primarily found in animal products, those following vegetarian or vegan diets are at higher risk of deficiency. Regular B12 supplementation or consumption of fortified foods is often necessary for these individuals.

Are there any plant-based sources of B12. While some plant foods are fortified with B12, there are no reliable natural plant sources of this vitamin. Vegans and vegetarians should rely on fortified foods or supplements to meet their B12 needs.

Individuals with Gastrointestinal Disorders

People with conditions such as Crohn’s disease, celiac disease, or those who have undergone gastric bypass surgery may have difficulty absorbing B12. These individuals often require higher doses or alternative forms of supplementation, such as sublingual tablets or injections.

The Role of Vitamin B12 in Overall Health

Beyond its well-known functions in red blood cell formation and neurological health, vitamin B12 plays several other crucial roles in the body:

DNA synthesis: B12 is essential for the production and regulation of DNA, the genetic material in all cells.
Energy metabolism: It helps convert food into glucose, providing energy for the body.
Fatty acid synthesis: B12 is involved in the metabolism of fatty acids, which are important for cell membranes and energy storage.
Immune function: Adequate B12 levels support a healthy immune system.
Mood regulation: B12 plays a role in producing brain chemicals that affect mood and other brain functions.

Can B12 supplementation improve mood in people without deficiency. While B12 is important for mood regulation, there’s limited evidence to suggest that supplementation improves mood in individuals with normal B12 levels. However, correcting a deficiency can lead to significant improvements in mood and cognitive function.

Interaction with Other Nutrients

Vitamin B12 works in conjunction with other nutrients, particularly folate (vitamin B9). Both are involved in the production of red blood cells and DNA synthesis. A deficiency in either can lead to similar symptoms, which is why they’re often considered together in medical assessments.

Other nutrients that interact with vitamin B12 include:

Iron: Both B12 and iron are necessary for healthy red blood cells.
Vitamin C: This vitamin can enhance the absorption of non-heme iron, which is important for overall red blood cell health.
Calcium: High doses of calcium can interfere with B12 absorption, although this is rarely a problem with normal dietary intake.

Future Directions in B12 Research

As our understanding of vitamin B12’s role in health continues to evolve, several areas of research are gaining attention:

Neurodegenerative Diseases

Researchers are investigating the potential role of B12 in preventing or slowing the progression of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. While current evidence is not conclusive, this remains an active area of study.

Personalized Nutrition

Advances in genetic testing may lead to more personalized recommendations for B12 intake. Some individuals may have genetic variations that affect their B12 metabolism, potentially requiring different levels of supplementation.

Novel Delivery Methods

Research is ongoing into new ways to deliver vitamin B12, particularly for individuals with absorption issues. This includes improved sublingual formulations, nasal sprays, and transdermal patches.

Could new delivery methods improve B12 absorption in people with gastrointestinal disorders. Innovative delivery methods that bypass the gastrointestinal tract could potentially improve B12 absorption in individuals with conditions that affect nutrient uptake. However, more research is needed to establish the efficacy and safety of these new approaches.

B12 and Gut Microbiome

Emerging research is exploring the relationship between vitamin B12 and the gut microbiome. Some studies suggest that certain gut bacteria may produce small amounts of B12, while others may compete for dietary B12. Understanding these interactions could lead to new strategies for optimizing B12 status.

Conclusion

Vitamin B12 deficiency is a complex condition with far-reaching health implications. From its role in preventing anemia and supporting neurological function to its potential impact on cardiovascular health and cognitive performance, B12 is truly a vital nutrient. Recognizing the symptoms of deficiency, understanding risk factors, and ensuring adequate intake through diet or supplementation are crucial steps in maintaining optimal health.

As research continues to uncover new aspects of B12’s function in the body, our approach to diagnosis, treatment, and prevention may evolve. For now, awareness of the importance of this vitamin and regular monitoring, especially for at-risk groups, remain key strategies in combating B12 deficiency and its associated health risks.

Remember, while shortness of breath can be a symptom of B12 deficiency-related anemia, it’s always important to consult with a healthcare professional for proper diagnosis and treatment. Vitamin B12’s role in overall health extends far beyond its impact on breathing, touching nearly every system in the body. By staying informed and proactive about B12 intake, individuals can take an important step towards safeguarding their health and well-being.

Vitamin B12 deficiency: Symptoms, complications, and more

A vitamin B12 deficiency can lead to nerve and brain damage and anemia. Early symptoms include weakness, constipation, and depression. It can result from dietary factors, medication use, and some underlying conditions.

Vitamin B12 is vital for creating and maintaining nerve and red blood cells, it supports the nervous system, and it helps create DNA, the basis of all cells.

Without treatment, vitamin B12 deficiency can lead to anemia. It can also result in nerve and brain damage. According to the Office of Dietary Supplements (ODS), the damage may be irreversible in the long term.

This article looks at how to recognize B12 deficiency, who is at risk, and how to treat or prevent it.

According to the National Health Service (NHS) in the United Kingdom, a person with vitamin B12 deficiency may develop anemia and other symptoms.

Low levels of B12 can lead to:

fatigue and weakness
constipation
loss of appetite and weight loss
problems with balance
depression
problems with thinking
a sore mouth or tongue

In infants, signs of a deficiency include:

not growing or developing at the expected rate
problems with movement
megaloblastic anemia

Anemia and neurological problems can lead to further symptoms and complications.

Anemia

Body cells need vitamin B12 to reproduce. If a person does not have enough vitamin B12, their body cannot make enough red blood cells. This can result in anemia.

The hallmark symptom of B12 deficiency is megaloblastic anemia, in which the red blood cells are immature and larger than usual. This affects their ability to deliver oxygen effectively to the body.

Common symptoms of anemia are:

fatigue
shortness of breath
feeling faint
headaches
pale or yellowish skin
heart palpitations
tinnitus (ringing in the ears)
reduced appetite and weight loss

Neurological symptoms

A vitamin B12 deficiency can also lead to neurological symptoms, such as:

numbness and tingling in the hands and feet
problems with thinking and memory
confusion
problems with balance
changes in gait and other movements

Long-term B12 deficiency may increase the risk of various health problems. One reason for this may be that the body needs vitamin B12 to process homocysteine.

Experts have found links between high levels of homocysteine and some health conditions, such as dementia and cardiovascular disease.

Dementia and thinking

Low levels of vitamin B12 may affect brain health in the long term and increase the risk of cognitive decline.

Depending on the person’s age, it may lead to:

reduced school performance in children
irritability
memory loss
depression
dementia

Some research has found higher levels of homocysteine in people with Alzheimer’s and dementia.

In 2012, researchers published the results of a study involving 121 people aged 65 years and over.

First, they tested the participants’ blood to identify levels of vitamin B12 and other markers of B12 deficiency. They also assessed their memories and other thinking skills.

After 52 months, they carried out MRI scans of the participants’ brains. They checked for brain size and any signs of brain damage.

Results showed that those with the strongest signs of vitamin B12 deficiency in the initial tests were much more likely to have lower cognitive test scores and smaller total brain volumes after 52 months.

Neurological damage

Studies have shown that 20–30% of people with B12 deficiency have neurological damage, such as:

nerve damage
damage to the spinal cord
neurological problems that affect mental health

Cardiovascular disease

Experts have also found high levels of homocysteine in people with coronary heart disease and stroke.

However, there is not enough evidence to recommend B12 supplementation to prevent heart disease.

Energy levels

Some people use B12 supplements to boost energy levels and athletic performance. However, supplements only appear to help if a person already has a deficiency.

The amount of vitamin B12 an individual needs per day will depend on their age. People also need more B12 during pregnancy and while breastfeeding.

According to the ODS, the average daily recommended amounts for different ages in micrograms (mcg) are:

0–6 months	0.4 mcg
7–12 months	0.5 mcg
1–3 years	0.9 mcg
4–8 years	1.2 mcg
9–13 years	1.8 mcg
14 years and over	2.4 mcg
During pregnancy	2.6 mcg
While breastfeeding	2.8 mcg

A B12 deficiency can occur if a person does not consume enough of the vitamin in their diet or if their body cannot absorb it effectively during digestion.

When a person consumes food that contains vitamin B12, the body takes two steps to absorb it.

First, hydrochloric acid in the stomach separates it from the protein it binds to in food.

Then, vitamin B12 combines with another protein that the stomach produces, called intrinsic factor. Then, the intestines can absorb it.

Here are some possible causes of vitamin B12 deficiency.

1) Pernicious anemia

Pernicious anemia is an autoimmune disease that affects the gut’s ability to digest vitamin B12.

When a person has pernicious anemia, their immune system creates antibodies that attack the stomach’s lining. There, they damage cells that produce intrinsic factor.

If the stomach cannot produce intrinsic factor, the intestines will be unable to absorb vitamin B12.

2) Bowel problems

Some people may have problems absorbing vitamin B12 into their bloodstream because of a condition that affects their stomach or small intestine.

Possible causes include:

Crohn’s disease
celiac disease
surgery that reduces the size of the stomach or the length of the intestine

These people can experience malnutrition because they cannot absorb enough vitamins, water, and other nutrients.

3) Diet

People who follow a vegan or vegetarian diet may have a higher risk of B12 deficiency. During pregnancy, this may increase the risk of neurological damage in a fetus.

While some plant foods contain vitamin B12, it is often in a form that the body cannot absorb efficiently, according to research published in 2013.

People who follow a plant-based diet can supplement their B12 intake by eating fortified foods, such as nutritional yeast products.

4) Medications

Some medications can affect the body’s ability to digest vitamin B12, leading to a deficiency.

Examples include proton pump inhibitors (PPIs) and Histamine h3 receptor agonists (h3 blockers), which doctors prescribe to treat indigestion, heartburn, and gastroesophageal reflux disease (GERD).

PPIs prevent the stomach from producing acid, but the body needs acid to absorb vitamin B12.

5) Functional vitamin B12 deficiency

Some people appear to have enough vitamin B12 in their blood, but they do not have the proteins they need to transport it between cells. This means the body cannot use it effectively.

They can develop neurological symptoms related to B12 deficiency.

To assess for a vitamin B12 deficiency, a doctor will likely:

ask about symptoms
carry out a physical examination
do a blood test to measure B12 levels and check for anemia
do other tests to rule out other conditions and check for pernicious anemia, if necessary

Some people will have a B12 deficiency but no symptoms. A doctor may recommend regular testing for people with long-term gastrointestinal problems to ensure a deficiency does not develop.

Getting an early diagnosis can help prevent long-term complications.

Treatment will depend largely on the cause of a deficiency.

Options include increasing vitamin B12 intake through:

intramuscular injections
oral medicine
adding foods that are rich in B12 to the diet

Some people may need regular injections for the rest of their life.

Most people can prevent B12 deficiency through dietary choices, but this is not always the case.

People following a plant-based diet

People whose diet is largely or wholly plant-based should ensure their B12 intake is adequate.

Dietary options include:

fortified breakfast cereals
fortified nutritional yeast
fortified soy milk

Learn more about supplements that are suitable for people on a vegan diet.

People who eat meat or fish

For those who eat meat or fish, a balanced diet containing fish, meat, and dairy foods should have enough B12 for human requirements.

Other conditions and medical treatments

Anyone who has a chronic gastrointestinal condition or believes they may have symptoms of B12 deficiency should seek medical advice.

The doctor will seek to identify the cause and treat it accordingly.

Good sources of vitamin B12 include the following:

clams
beef liver
fish, such as trout, salmon, and tuna
nutritional yeast
dairy products
eggs
fortified yeasts and other foods

Get some more tips here on vitamin B12 sources.

Vitamin B12 is essential for preventing anemia and maintaining neurological health. It may help prevent dementia and heart disease.

A balanced diet can often help prevent a deficiency. People who eat only plant-based foods may consider including fortified foods or asking a doctor about supplements.

A doctor may also recommend supplements if a person has pernicious anemia, Crohn’s disease, or another condition that affects their ability to absorb vitamin B12.

Suspected vitamin B-12 deficiency

Researchers believe that up to 15 percent of people in the United States have vitamin B-12 deficiency. Signs and symptoms of deficiency include:

confusion
dementia
depression
difficulty maintaining balance
fast heartbeat
numbness and tingling in the hands and feet
poor memory
a sore mouth or tongue

Infants with vitamin B-12 deficiency may fail to thrive. They may experience movement problems in addition to delayed development.

Pernicious anemia

People with symptoms of pernicious anemia may also need a vitamin B-12 level test. Pernicious anemia, which causes low levels of red blood cells, results from an inability to absorb vitamin B-12.

It often affects older adults or those who are lacking intrinsic factor. Intrinsic factor is a substance in the stomach that binds to vitamin B-12 so that the body can absorb it.

Symptoms of pernicious anemia include:

constipation
fatigue
loss of appetite
pale skin
weakness
weight loss

High serum folate levels

Serum folate is the level of folic acid in the blood. High serum folate levels can mask the symptoms of vitamin B-12 deficiency and make its neurological symptoms worse.

They can also increase the likelihood of anemia.

Symptoms of other conditions

An abnormally high vitamin B-12 status can be an early sign of liver disease, diabetes, or certain types of leukemia. A doctor may use the results of a vitamin B-12 test to help form their diagnosis.

Share on PinterestChildren and older adults are more likely to experience low vitamin B-12 levels.

Certain people are more at risk of vitamin B-12 deficiency than others, especially those who have low stomach acid or other digestive issues. Stomach acid separates vitamin B-12 from food so that the body can absorb it more efficiently.

The following groups of people are more likely than others to experience low vitamin B-12 levels:

older adults
children
vegans and vegetarians
people with diabetes
people with conditions that reduce vitamin B-12 absorption, including celiac disease and Crohn’s disease
people who have had gastric bypass surgery
those who are breast-feeding
people who are taking medicines such as chloramphenicol, proton pump inhibitors, or h3 blockers

Doctors usually use a blood test to check vitamin B-12 status, but home urine tests are also available. A doctor can check vitamin B-12 as part of a standard blood test.

Although it is not necessary to fast before a B-12 test, a person may need to if the doctor is also using the test to look at other components in the blood.

It is important that individuals tell their doctor about any medications and supplements they are taking, as some can affect the results.

The results may be:

Low. Levels of vitamin B-12 are low if they are below 200 pg/mL. This result suggests a vitamin B-12 deficiency, pernicious anemia, or an overactive thyroid. People with low vitamin B-12 levels often experience neurological symptoms.
High. An abnormally high vitamin B-12 status is anything over 900 pg/mL. This result may suggest liver or kidney problems, diabetes, or certain forms of leukemia.

The result ranges vary from one laboratory to another, so it is important to discuss the results and their meaning with a doctor.

The doctor may also check the levels of methylmalonic acid (MMA) and other substances to evaluate for vitamin B-12 deficiency. These lab values help detect a vitamin B-12 deficiency during the early stages.

Individuals with low vitamin B-12 levels often require regular injections of the vitamin. These shots are more effective than supplements at raising vitamin B-12 levels, especially when people have medical conditions that may make it more difficult to absorb supplements.

For some people, high doses of vitamin B-12 supplements may improve B-12 status. Supplements are available in capsule or liquid form from pharmacies, supermarkets, health stores, and online. It may also be helpful to eat more foods that are rich in vitamin B-12.

There is no upper limit for vitamin B-12 intake because consuming high levels does not cause problems. However, having naturally high levels of vitamin B-12 in the body may be a cause for concern, as it suggests a severe underlying condition. Doctors will aim to treat the underlying medical condition, rather than the elevated levels of vitamin B-12.

Share on PinterestEggs are rich in vitamin B-12.

Although absorption difficulties and other medical issues often cause low vitamin B-12 levels, some people may be deficient because they do not get enough vitamin B-12 from their diet. This is especially true for vegans and long-term vegetarians.

Foods rich in vitamin B-12 include:

fish and seafood
meat
eggs
dairy products
fortified plant-based dairy alternatives
fortified breakfast cereals
fortified nutritional yeast

Vitamin supplements can make up for a shortfall in the diet, especially for vegans and strict vegetarians. As it can be easier for their body to absorb supplements than naturally occurring vitamin B-12, older adults should aim to meet their vitamin B-12 needs through fortified foods and vitamin supplements.

Recommended dietary allowances of vitamin B-12

Adults and adolescents over 14 years of age require 2.4 micrograms (mcg) of vitamin B-12 daily. This increases to 2.6 mcg during pregnancy, and 2.8 mcg when breast-feeding.

Vitamin B-12 is an essential nutrient that plays a vital role in overall health. A vitamin B-12 level test determines a person’s vitamin B-12 status. A doctor may recommend this test to people who have symptoms of a deficiency or who have a higher risk of low vitamin B-12 in the body.

People can avoid vitamin B-12 deficiency by eating a balanced diet and including several sources of vitamin B-12 daily or taking supplements. If they have issues absorbing vitamin B-12 from food sources, oral supplements or injections of the vitamin can help to prevent symptoms and complications.

Causes of vitamin B12 deficiency

malabsorption 90 032
Vitamin B12 malabsorption can be caused by many causes such as anemia in autoimmune gastritis, surgical removal of the stomach, chronic inflammation of the pancreas, intestinal parasites, genetic disorders, and certain medications.
Because the ability to absorb B12 from food decreases with age, deficiency is more common in older people. However, B12 deficiency can also occur in children and young adults.
Inadequate diet
Vitamin B12 deficiency can be caused by malnutrition or improper diet, such as a vegetarian diet.

Vitamin B12 deficiency symptoms

Vitamin B12 is an essential nutrient needed for the proper functioning of the brain and nervous system, and for the formation of red blood cells. Vitamin B12 deficiency can cause a variety of symptoms.

Let’s look at the 5 main symptoms of vitamin B12 deficiency.

Fatigue and weakness
Vitamin B12 is essential for the production of red blood cells, which are responsible for carrying oxygen from the lungs to the tissues of the body. When the body is deficient in vitamin B12, it can lead to a decrease in the number of red blood cells, leading to a condition called anemia.
Anemia can cause a range of symptoms including fatigue, weakness, shortness of breath and dizziness. Oxygen is necessary for the production of energy in the body, and without it, the cells and tissues of the body cannot function normally. Shortness of breath occurs due to the fact that the body does not receive enough oxygen due to a decrease in the number of red blood cells. Dizziness can also occur due to a lack of oxygen in the brain.
Vitamin B12 is involved in the metabolism of carbohydrates, fats and proteins, which are the main sources of energy in the body. Without enough vitamin B12, the body’s ability to produce energy from these nutrients is reduced, leading to fatigue and weakness.
Neurological problems
Studies have shown that vitamin B12 deficiency can cause changes in the structure and function of the brain, which can lead to cognitive decline and memory loss. Vitamin B12 plays an important role in the production of myelin, a fatty substance that forms a protective sheath around nerve fibers in the brain. Without enough vitamin B12, the myelin sheath can be damaged, causing problems with nerve impulse transmission and cognitive function.
Vitamin B12 plays a role in the synthesis of neurotransmitters such as serotonin and dopamine, which are important for mood, memory and cognitive functions. Without enough vitamin B12, the production of these neurotransmitters can be disrupted, which can lead to cognitive decline and memory loss.
Nerve damage caused by vitamin B12 deficiency can cause numbness or tingling in the hands and feet. Vitamin B12 deficiency can cause difficulty walking and balance problems.
Mouth and tongue problems
Vitamin B12 is essential for the proper functioning of the cells in the mouth and digestive system. When the body is deficient in vitamin B12, it can lead to a condition called glossitis, which is an inflammation of the tongue. Glossitis causes swelling, redness, and soreness of the tongue, making it difficult and painful to eat or speak.
Vitamin B12 deficiency can also lead to cold sores or sores, which are small, painful sores that develop in the mouth. These sores can occur on the tongue, lips, gums, or inside of the cheeks. Vitamin B12 deficiency can weaken the immune system, making it easier for bacteria to infect the mouth and cause ulcers.
Digestive problems
Vitamin B12 plays an important role in the proper functioning of the digestive system, including the absorption of nutrients and the regulation of bowel movements. When the body is deficient in vitamin B12, it can lead to a change in bowel habits. Studies have shown that vitamin B12 deficiency can lead to gastrointestinal symptoms such as constipation, diarrhea, bloating, and loss of appetite. These symptoms may be related to disruption of the normal digestive processes, which can affect the movement of food through the intestines.
Vitamin B12 deficiency can lead to a condition called bacterial overgrowth in the small intestine. It occurs when there is an overgrowth of bacteria in the small intestine, which can lead to gastrointestinal symptoms such as diarrhea, bloating, and abdominal pain.
Vision problems
Vitamin B12 is important for the proper functioning of the nervous system, including the nerves that control vision. When the body is deficient in vitamin B12, it can cause neurological symptoms, including vision problems. Research has shown that vitamin B12 deficiency can cause changes in the optic nerve, which is responsible for transmitting visual information from the eyes to the brain. This can lead to vision problems such as blurred vision, double vision or blurred vision.

Summary

Vitamin B12 supplements can interact with certain medications, such as metformin used for diabetes, proton pump inhibitors used for acid reflux, and some antibiotics. Taking more than the recommended dose of vitamin B12 can cause side effects such as acne, diarrhea, and upset stomach. Although vitamin B12 is generally considered safe, long-term use of high doses can cause skin reactions and problems such as anemia.
