What else can I help you with?
A deficiency of folic acid and vitamin B12 decreases RBC production by?
Decreasing the synthesis of DNA molecules.
What does vitamin do for our body?
You can become anemic if you have a B12 deficiency. The vitamin is needed to make hemoglobin for your red blood cells.
Which nutrients are required for the synthesis of haemoglobin?
The synthesis of hemoglobin requires several key nutrients, including iron, vitamin B6, vitamin B12, and folate. Iron is essential for the formation of heme, the iron-containing component of hemoglobin. Vitamins B6 and B12, along with folate, play crucial roles in the production of red blood cells and the synthesis of nucleic acids necessary for hemoglobin production. A deficiency in any of these nutrients can lead to impaired hemoglobin synthesis and anemia.
Which vitamin is important for hemoglobin?
Hemoglobin is a protein in red blood cells that carries oxygen from the respiratory organs to the rest of the body by way of the blood. When someone is lacking in hemoglobin, the condition is known as anemia. Iron is an important vitamin for hemoglobin production, as it increases resistance to stress and disease and improves blood quality. Vitamin C supports the absorption of iron, so it is also necessary to have enough vitamin C for healthy blood.
Intrinsic factor decreases with the age?
Intrinsic factor is a protein produced by the stomach that is essential for the absorption of vitamin B12. As people age, the production of intrinsic factor can decrease, leading to a higher risk of vitamin B12 deficiency. This deficiency can result in anemia and neurological issues, as vitamin B12 is crucial for red blood cell formation and proper nerve function. Therefore, older adults may need to monitor their vitamin B12 levels more closely.
Is vitamin K deficiency a cause of bleeding disorders?
Vitamin K is necessary for the production of Clotting Factors II, VII, IX and X. So a vitamin K deficiency could lead to a bleeding disorder. Additionally vitamin K is necessary for the production of the anticoagulant protein C and protein S. Inhibition of Vitamin K function is also associated with clotting disorders though for this to occur there has to be a deficiency in either proteins C or S.
How is vitamin A deficiency treated?
Vitamin A deficiency can be prevented or treated by taking vitamin supplements or by getting injections of the vitamin.
What can cause Microcytosis?
Microcytosis, characterized by smaller-than-normal red blood cells, can be caused by several factors, primarily iron deficiency anemia, where insufficient iron affects hemoglobin production. Other causes include thalassemia, a genetic disorder affecting hemoglobin synthesis, and chronic diseases that impact erythropoiesis. Additionally, lead poisoning and certain nutritional deficiencies, such as vitamin B6 deficiency, can also contribute to microcytosis.
Why anemia occurs in osteomalacia?
Osteomalacia is associated with deficiency of Vitamin D (deficiency may be due to low dietry intake, less exposure to sunlight etc). Studies have shown that vitamin D has influence on RBC formation. Vitamin D somehow increases RBC production. Hence osteomalacia secondary to Vitamin D deficiency is associated with anemia.
What is the most common deficiency worldwide?
Iron deficiency is the most common nutrient deficiency worldwide, affecting about a quarter of the global population. Iron is essential for producing hemoglobin, which carries oxygen in red blood cells. Deficiency can lead to anemia and other health complications.
What vitamins increases hemoglobin?
vitamins only help in increase the hb. every vitamin have its own features such as vit.a improve eyesight. in deficiency of b12 there would be macrocytic hypochromic anaemia. vitamin c protect the body from inf. in vit. d deficiency there would be weakness of bones.etc.etc.
Why does hemoglobin decrease in diarrhea?
There are a number of reasons why hemoglobin may decrease in diarrhea. Some of these causes could be from a vitamin B12 deficiency, folate deficiency, colorectal cancer, alcoholism or lymphoma.
