Your doctor will conduct a full medical examination to diagnose anemia and rule out another significant illnesses. Megaloblastic anemia of any sort must be properly diagnosed and treated because serious problems with muscles and balance may occur if anemia due to vitamin B12 deficiency is treated with folic acid alone. The symptoms of this disorder come on gradually and may not be immediately recognized.
Pernicious anemia usually affects adults. Vitamin B12 injections are the traditional treatment for pernicious anemia, but the supplement can also be taken orally in large doses. Lack of intrinsic factor is thought to be caused by a genetic deficiency or an autoimmune disorder. Intrinsic factor-a chemical substance secreted by cells in the stomach that makes absorption of vitamin B12 possible. Pernicious anemia is a form of megaloblastic anemia caused by the absence of Removal of parts of the stomach or small intestine.
Inadequate intake or absorption of foods rich in folic acid, such as green vegetables, whole grains, legumes, leafy greens, broccoli, Brussels sprouts, asparagus, citrus fruits, strawberries, wheat germ, and brewer's yeast.Inadequate intake or absorption of foods with a high B12 content, such as meat, poultry, fish, cheese, milk, and eggs.Therefore, people who have malabsorption are also at risk for B12 deficiency.Ĭauses of the megaloblastic anemias include: From the stomach, B12 travels down the intestines where it is absorbed into the body in the small intestines. Acid helps to release the active form of vitamin B12 in the stomach. Thus, vegetarians who consume dairy and egg products are not at increased risk for B12 deficiency, while individuals who are strict vegans (and their breastfed infants) are most at risk forĪging also affects B12 status because less acid is produced in the stomach as we age. Will increase folic acid requirements as well. Pregnancy, breastfeeding, and periods of rapid growth, which increase the body's need for folic acid, can also contribute to anemia. The result is that fewer red blood cells are produced and available to carry oxygen to the body's cells, resulting in anemia.Ī decreased intake of folic acid from food can result in anemia. Thus cells that need rapid replenishment, such as blood cells, are most often affected by a deficiency of these vitamins. This type of anemia is primarily associated with inadequate intake or utilization ofįolic acid-2 vitamins necessary for cell division. Other than women of childbearing age, children and teens are the next most likely to suffer from iron-deficiency anemia. Chronic diseases that interfere with nutrition or cause bleeding, such as inflammatory bowel diseases.Iron-deficiency anemia can be caused by the following: Because women lose iron in red blood cells during menstruation, anemia can result if the iron is not replaced. In the US, women of childbearing age are more likely to suffer from iron-deficiency anemia than men. The Nutritional Anemias Iron-Deficiency Anemia When you have anemia, your heart has to work harder to pump oxygen-rich blood through your body. This in turn can affect your energy level greatly. Any change in the size, function, or amount of these cells affects how oxygen is transported within your body. Red blood cells-with the help of iron-containing hemoglobin-move oxygen from your lungs to bodily tissues. Here, we will discuss 3 forms of anemia that are related to nutrition.Īnemia is any blood disorder in which the number of the red blood cells are low or the hemoglobin content in the red blood cells is low. Is the most common nutritional deficiency in the world, there are other types. If you are feeling exhausted despite lots of sleep, have decreased energy, and seem to be unusually pale, the culprit could be some form of anemia.
