Vitamin B12 deficiency, also known as hypovitaminosis B12, is a medical condition that occurs when the body does not have sufficient amounts to function properly. Vit-B12 plays a crucial role in the human body as it is involved in several vital functions, including the formation of red blood cells, maintenance of the nervous system and cellular metabolism.
Causes of Vitamin B12 Deficiency
The main cause of vitamin B12 deficiency is lack of adequate dietary intake. Vit-B12 is mainly found in foods of animal origin, such as meat, fish, dairy products and eggs. Therefore, people who follow vegetarian or vegan diets are at greater risk of developing this deficiency unless they take vit-B12 supplements or consume fortified foods.
Low Consumption: A diet low in b12 can lead to its deficiency.
Bariatric: Some types of bariatric surgery can reduce significant parts of the intestine, leading to low concentrations in the body.
Medicines: Some classes of medications (proton inhibitors, cholestyramine, H2 antihistamines, metformin, antibiotics, omeprazole, esomeprazole and pantoprazole) can cause problems with vitamin absorption.
Digestive Problems: People who have Crohn's or celiac disease do not absorb vitamin B12 correctly and may have a deficiency.
Excessive alcohol consumption
Symptoms Caused by B12 Deficiency
Symptoms of vitamin B12 deficiency can range from fatigue and weakness to serious neurological problems, such as numbness and tingling in the hands and feet. If left untreated, B12 deficiency can lead to serious complications such as megaloblastic anemia and permanent damage to the nervous system.
Fatigue, shortness of breath, tingling, as well as paleness (especially of hands and feet) are the main symptoms. Furthermore, in children in the developmental phase, hypovitaminosis of B12 can lead to delays in development and growth.
Vitamin B12 contains cobalamin, which is very important for the maintenance and development of the central nervous system. Likewise, it helps maintain heart health and blood formation in the bone marrow.
Other common symptoms are loss of sensation in the lower limbs, eye twitching, tremors and palpitations, sores in the oral region, memory loss and loss of appetite.
Treatment of B12 Hypovitaminosis
It is important to diagnose and treat vitamin B12 deficiency early to avoid long-term complications. Treatment usually involves administering vit-B12 supplements orally or injectably, depending on the severity of the deficiency.
Therefore, in cases of suspicion due to the symptom, it is recommended to seek a specialist doctor to check your health status. Furthermore, in cases of children, the doctor should be consulted as soon as possible, as low levels of vitamin B12 can cause irreversible damage.
The main treatments involve intramuscular injections of vit-B12 (concentration of 100 mcg) in the form of hydroxocobalamin (mainly in cases of pernicious anemia); supplements and multivitamins; dietary re-education with foods rich in vit-B12 such as milk, beef liver, eggs, cheese, crustaceans, yogurt, chicken, fish and yeast.
How to find out if your Vitamin B12 is low?
In addition to checking your health status with a doctor, he or she will order some tests to reach a diagnosis. In this sense, you can take tests and check if you have a B12 deficiency.
The tests recommended to check the lack of vitamin are the complete blood count that analyzes the amount of red blood cells and hemoglobin, as well as the shape, size and color. Furthermore, it is good to analyze the levels of folate and vitamin B12 (also known as cyanocobalamin) through biochemical tests.
Levels considered normal for vitamin B12 are 200 to 800 pg/ml.
