Signs And Symptoms Of Deficiency Of Vitamin B12
Our body needs various nutrients to function properly, and one of them is vitamin B12. It is an essential nutrient that plays a crucial role in the formation of red blood cells, DNA synthesis, and proper functioning of the nervous system. However, our body cannot produce this vitamin on its own, and we need to get it from food or supplements.
Unfortunately, many people are deficient in vitamin B12, and they don't even realize it. The symptoms of this deficiency can be subtle and can gradually worsen over time. In this article, we will discuss the signs and symptoms of vitamin B12 deficiency.
What Causes Vitamin B12 Deficiency?
Vitamin B12 deficiency can occur due to various reasons. One of the most common reasons is a lack of this nutrient in the diet. Vegetarians and vegans are more prone to this deficiency as they don't consume animal-based products that are rich in vitamin B12.
Another cause of vitamin B12 deficiency is the inability of the body to absorb this nutrient. This can happen due to various health conditions such as pernicious anemia, atrophic gastritis, or celiac disease. People who have undergone gastrointestinal surgery or have digestive disorders such as Crohn's disease or ulcerative colitis are also at risk of vitamin B12 deficiency.
Signs And Symptoms Of Vitamin B12 Deficiency
Vitamin B12 deficiency can cause various signs and symptoms that can affect different parts of the body. Here are some of the most common signs and symptoms:
1. Fatigue And Weakness
One of the most common symptoms of vitamin B12 deficiency is fatigue and weakness. This happens because vitamin B12 helps in the formation of red blood cells that transport oxygen throughout the body. When there is a deficiency of vitamin B12, the red blood cells become larger and less efficient, leading to fatigue and weakness.
2. Pale Skin
Vitamin B12 deficiency can cause pale skin as it affects the production of red blood cells. The lack of red blood cells leads to less oxygen reaching the skin, making it appear pale.
3. Tingling Sensation In Hands And Feet
Vitamin B12 deficiency can also cause a tingling sensation in the hands and feet. This happens because vitamin B12 is essential for the proper functioning of the nervous system. When there is a deficiency of vitamin B12, the nerves can get damaged, leading to a tingling sensation.
4. Difficulty In Walking
In severe cases, vitamin B12 deficiency can cause difficulty in walking. This happens due to the damage to the nervous system, which affects the coordination and balance of the body.
5. Mouth Ulcers
Vitamin B12 deficiency can cause mouth ulcers, which are painful sores that appear on the inside of the mouth. These ulcers can make it difficult to eat or talk.
6. Vision Problems
Vitamin B12 deficiency can also cause vision problems. This happens because vitamin B12 is essential for the proper functioning of the optic nerve that transmits visual information from the eyes to the brain.
7. Mood Changes
Vitamin B12 deficiency can cause mood changes, including depression, irritability, and anxiety. This happens because vitamin B12 is essential for the production of neurotransmitters that regulate mood.
8. Memory Problems
Vitamin B12 deficiency can also cause memory problems, including forgetfulness and confusion. This happens because vitamin B12 is essential for the proper functioning of the brain.
How To Prevent Vitamin B12 Deficiency?
The best way to prevent vitamin B12 deficiency is to consume foods that are rich in this nutrient. Animal-based products such as meat, fish, eggs, and dairy products are excellent sources of vitamin B12. If you are a vegetarian or vegan, you can get vitamin B12 from fortified foods such as plant-based milk, breakfast cereals, and nutritional yeast.
If you are unable to get enough vitamin B12 from your diet, you can take supplements. Vitamin B12 supplements are available in different forms such as tablets, capsules, and injections. However, it is always best to consult a healthcare professional before taking any supplements.
