What is vitamin B12?
One of the most crucial nutrients for maintaining healthy neurons and blood cells is vitamin B12. The genetic material found in every cell of your body, DNA, is synthesized with its help. The human body cannot synthesize vitamin B12. To acquire vitamin B12, you must eat or drink things that already contain it.
Foods and beverages derived from animals, such as meat, dairy, and eggs, are good sources of vitamin B12. Some cereals, bread, and nutritional yeast are enriched with additional vitamins and nutrients; this is another place you might find it.
Vitamin B12 requirements increase during pregnancy and lactation, although adults only need about 2.4 mcg daily. Children and infants require different amounts of vitamin B12 depending on their age.
What is vitamin B12 deficiency?
Anemia caused by insufficient vitamin B-12 and folate is known as deficiency anemia. This may occur if your body has problems absorbing or processing the B-12 and folate vitamins or if you need to consume more of these nutrients through diet.
Red blood cells made by the body without these substances are abnormally big and ineffective, lessening the amount of oxygen they can transport.
How is vitamin B12 deficiency diagnosed?
Because symptoms aren't always present or can be comparable to other dietary deficiencies, vitamin B12 insufficiency can be difficult to detect. Healthcare providers typically conduct routine blood testing to detect it in high-risk patients.
Vitamin B12 blood test levels and complete blood counts (CBCs) are the diagnostic tools for vitamin B12 deficiency. When the vitamin B12 level in the blood falls below 150 per milliliter, it is considered a diagnosis of vitamin B12 deficiency.
Symptoms of vitamin B12 deficiency
Possible symptoms include lightheadedness, difficulty breathing, and exhaustion. Vitamin supplements can be administered orally or intravenously to remedy the deficits.
Walking difficulties
The inability to move freely is a long-term symptom of peripheral nerve injury. Someone who experiences numbness in their feet and limbs may find it challenging to walk unassisted. Muscle weakness and impaired reflexes are other symptoms that they can encounter.
Pale skin
A pale complexion and yellowing of the skin, known as jaundice, can be symptoms of a vitamin B12 deficiency. These variations in skin tone can occur when red blood cell production is inadequate.
Red blood cell deficiency can cause skin pallor. Vitamin B12 is involved in the process of making red blood cells. A jaundice-associated disorder known as megaloblastic anemia can result from a vitamin B12 deficiency, which in turn causes a shortage of red blood cells.
This form of anemia can weaken red blood cells (RBCs), leading to accelerated breakdown by the body. Bilirubin, a brownish substance, turns the skin yellowish, indicative of jaundice.
Fatigue
According to a reliable source, a lack of vitamin B12, which can cause megaloblastic anemia, can make a person feel exhausted. A lack of red blood cells (RBCs) makes it difficult for the body to transport oxygen, leading to excessive fatigue.
Fast heart rate
Vitamin B12 deficiency can cause rapid heartbeat. If red blood cell counts drop too low, the heart may begin to pump quicker to compensate. By triggering this response, the body attempts to ensure enough oxygen gets to all of its systems.
Risk factors
Things that may increase your risk of vitamin deficiency anemia include:
-
Certain autoimmune diseases, including Crohn's disease, celiac disease, and type 1 diabetes.
-
Surgery to remove part of your stomach or intestine.
-
Older age.
-
Chronic alcohol use.
Causes of vitamin B12 deficiency
An autoimmune disorder that impacts the stomach is known as pernicious anemia. In the stomach, vitamin B12 is mixed with intrinsic factor, a protein. The distal ileum is a section of the intestines responsible for absorbing this vitamin B12 and intrinsic factor mixture.
The inability to absorb vitamin B12 is a symptom of pernicious anemia, which occurs when the immune system attacks the stomach cells responsible for producing the intrinsic factor.
How can I prevent vitamin B12 deficiency?
Vitamin B12 is found in various foods, including red meat, seafood, fowl, eggs, milk, and other dairy products. Fortified foods have added extra vitamins and minerals to meet dietary requirements that would otherwise be lacking. Some types of bread, nutritional yeast, plant milk, and breakfast cereals are fortified.
To determine if a food has vitamin B12 added, look at the nutritional data label.
Supplemental vitamin B12: vitamin B12 is included in several multivitamins. Additionally, you can find supplements that contain simply vitamin B12. See your doctor or pharmacist for assistance in selecting the most appropriate supplement.
Vitamin B12 Injections
If your anemia is severe, your doctor may recommend injectable vitamin B12. Typically, you will take it daily for two weeks until your symptoms improve. After that, you can start taking B12 pills instead.
If your B12 deficiency is caused by an autoimmune condition or something unrelated to nutrition, you may need injections every two or three months for the rest of your life.
The typical injection sites are the upper arm, thigh, or muscle. Your doctor or nurse can administer or teach you how to perform the injections. In most cases, side effects are mild; nevertheless, you should contact your doctor immediately if you notice any swelling in your ankles, an allergic response, or difficulty breathing.
A B12 injection won't help with weight loss or increased energy if your B12 levels are already normal. According to the research, adding more B12 to these places has not been beneficial.
Final words
B12 deficiency can cause a variety of symptoms, including fatigue, headaches, depression, pale or yellow skin, mental impairment, and pain and inflammation in the mouth and tongue. Many of the symptoms caused by low B12 levels are not specific to B12 deficiency, which can cause the condition to go undetected.
If you notice any of the aforementioned symptoms, make an appointment with your doctor as soon as possible; only then can you receive the diagnostic testing and treatment you need.
