2. Causes of anemia due to vitamin deficiency


Causes of vitamin deficiency anemia include:
Folate deficiency anemia. Folate, also known as vitamin B9, is a nutrient found mainly in fruits and vegetables. If you eat a diet lacking in these foods, it can lead to folate deficiency and lead to anemia. The inability to absorb folate from food can also lead to a deficiency. Most nutrients from food are absorbed in the small intestine, however in people with conditions of the small intestine, such as celiac disease or those who have surgery to remove the small intestine, it can cause difficulty in absorption. absorb folate or its synthetic form, folic acid. Heavy drinking and use of certain anti-seizure medications reduce or interfere with folate absorption. Pregnant and lactating women have an increased need for folate due to the nutritional needs of the infant, which, combined with an inadequate response to the increased nutritional requirements of the mother, can lead to shortage. Anemia due to vitamin B12 deficiency. Vitamin B12 deficiency can be caused by a diet lacking in vitamin B12, which is found mainly in meat, eggs, and dairy. Also, anemia when your small intestine cannot absorb vitamin B12 due to causes such as stomach or small intestine surgery, abnormal bacteria growth in the small intestine, or diseases of the intestinal tract, such as Crohn's disease or celiac disease. interfere with vitamin absorption. Intrinsic factor is a protein secreted by the stomach that combines with vitamin B12 and travels to the small intestine to be absorbed. Without intrinsic factor, vitamin B12 cannot be absorbed and makes your body deficient in this vitamin. Intrinsic factor deficiency may be due to an autoimmune reaction in which your immune system mistakenly attacks the stomach cells that produce this factor. Vitamin C deficiency anemia is caused by not getting enough vitamin C from foods. Or due to other reasons that weaken the ability to absorb vitamin C such as smoking.

You are pregnant and not taking a multivitamin. You have intestinal problems or other illnesses that interfere with vitamin absorption. You abuse alcohol. Alcohol interferes with the absorption of folate and vitamin C, as well as other vitamins. You take certain prescription medications that can block the absorption of vitamins, such as anti-seizure medications that can block folate absorption or antacids, and some medications used to treat type II diabetes that can interfere with the absorption of vitamins. interfere with B-12 absorption. Risk factors for folate deficiency anemia include:
Hemodialysis in kidney failure Cancer treatment because certain drugs used to treat cancer interfere with folate metabolism.

4. Complications of anemia due to vitamin deficiency


Vitamin deficiency increases the risk of many health problems:
Pregnancy complications. Pregnant women with folate deficiency may be more susceptible to complications, such as premature birth. Nervous system disorders. Although vitamin B-12 is important for the production of red blood cells, it is also important for the nervous system. If left untreated, vitamin B-12 deficiency can lead to mental confusion and forgetfulness because vitamin B-12 is essential for the normal functioning of the brain. Scurvy is caused by a lack of vitamin C in daily foods. Signs and symptoms of this rare disease include bleeding under the skin and around the gums.
