Vitamin B12 or Cobalamin is a water-soluble vitamin: Vitamin B12 consists of cobalt, hence the name cobalamin. It is a water-soluble vitamin. Vitamin B12 is necessary for the regulation of the nervous system, the formation of healthy red blood cells and the synthesis of DNA. When the body shows these symptoms, it means that you are deficient in vitamin B12 and need medical treatment as soon as possible.
Pale skin: Lack of vitamin B12 will affect the amount of red blood cells in the body, which in turn leads to anemia. This also affects skin color, because with a lack of vitamin B12, the skin is yellow or pale.
Frequent headaches: Headaches that recur with no other reason or cause, may be related to vitamin B12 deficiency. The headache is thought to be a neurological effect of cobalamin deficiency.
Gastrointestinal problems: When the body does not have enough vitamin B12, it leads to gastrointestinal problems such as diarrhea, nausea, constipation and bloating. While these symptoms overlap with some other gastrointestinal problems, if they occur alongside signs of vitamin B12 deficiency, you should get checked out.
Irritability: Vitamin B12 deficiency causes irritability in some individuals. Because the vitamin is involved in the normal functioning of the central nervous system, a lack of it can affect your mental health. Some studies also link vitamin B12 deficiency with the onset of depression and anxiety.
Other signs of vitamin B12 deficiency: Other signs of vitamin B12 deficiency are mouth ulcers, stinging sensations in the body, vision disturbances, and impaired cognitive function. Vitamin B12 anemia causes extreme fatigue, lethargy, shortness of breath, feeling faint, palpitations, and sometimes ringing in the ears.
Who is more at risk for vitamin B12 deficiency? Although vitamin B12 deficiency can happen to anyone, certain groups of people are at higher risk of developing it. The gastrointestinal health of older adults affects the body’s ability to absorb vitamin B12, so they are at a higher risk of being deficient in this vitamin. People with pernicious anemia, an autoimmune disease, are also more likely to have vitamin B12 deficiency. People with celiac disease and Crohn’s disease are also likely to have cobalamin deficiency. People who consume little or no animal products or are strict vegetarians tend to have lower levels of vitamin B12.
