Why does a patient have abnormal vital signs with folic acid deficiency?
This causes a type of anaemia known as macrocytic megaloblastic folate anaemia, causing all the signs of anaemia.
What is the relation between pernicious anemia and megaloplastic anemia?
the two terms are more or less interchangeable but they are not exactly the same. Pernicious anaemia refers specifically to a condition where B12 fails to absorb in the gut: intrinsic factor is necessary for this absorption and is secreted by gastric pareital cells. Failure to secrete this substance can be due to atrophy of the cells, their absence due to total or partial gasrectomy or from circulating autoimmune pareital cell antibodies. There are other causes of failure to absorb B12 such as Blind Loop Syndrome but this is not known as Pernicious Anaemia. Nor is folate deficiency however all these conditions are known as megaloblastic anaemias. The diagnostic features of all this group of anaemias include megaloblasts in the bone marrow and are morphologically indistinguishable whether caused by B12 deficiency (for whatever reason) or folate deficiency. As far as I know, the two terms are more or less interchangeable. Both apply to a kind of anaemia caused by a deficiency of either B vitamins B12 or B9 (folic acid). It is characterised by big red blood cells i.e. a raised MCV (mean cell volume). If one looks at the developing red cells in the bone marrow they have a characteristic appearance and are known as MEGALOBLASTS. Poor diet can be the cause of folic acid (folate) deficiency but the most likely cause of B12 deficiency is a failure to absorb the vitamin due to a problem in the gut. Both are easily treated. Injections of vitamin B12 will cause a remarkably quick recovery. Oral folate supplements will remedy this deficiency quickly too.
Ginny has been on antibiotics for an extended period A visit to her physician reveals that she has a vitamin K deficiency What is the cause and effect relationship here?
Sometimes antibiotics will cause vitamin K deficiencies. The antibiotic caused the bacteria in the intestines to go all sorts of crazy. When the good bacteria in the intestines is not right it can cause this deficiency.
What does fat deficiency cause?
A deficiency in fat can cause many problems. Having a fat deficiency can cause you to be deficient in the fat soluble vitamins (A, D, E and K) as fat is required for them to be absorbed by the intestines. So it can cause those vitamin deficiency symptoms as well as fat deficiency symptoms. I wasn't able to quickly find general fat deficiency symptoms, only essential fatty acid deficiency symptoms. So you can read all about that on a Google search. If you're wanting to know if fats are really that important to your health, then absolutely. They serve many essential functions in the body. They're a major component of every cell membrane in the body. If you're having health problems and you're wondering if it's due to a fat deficiency then you should consult with a doctor.
Can anemia cause acute respiratory deficiency?
The lungs oyegenate the red cells. They'll keep working at it all the harder with anemia.
Can a diuretic cause lung congestion?
I am no doctor, but if you are dehydrated and there isn't enough fluid in your lungs to think the mucus (we all have it), you're gonna get congested. diuretics can remove TOO MUCH fluid from your body.
How diuretics cause alkalosis?
Often when taking diuretics you are also prescribed Potassium(K). Because the most common "loop" diuretics cause you to pee out excess K. Alkalosis is a result of too much Bicarbonate (HCO3) or too little Hydrogen ion (H). Because of the processes and membranes of the kidney where the K goes the H follows. So if you are taking a loop diuretic and loosing too much K you are also loosing too much H resulting in alkalosis. This is not standard across the board for all diuretics and don't take K just because you are taking a diuretic - too much K can make your heart stop. It is a very fine balance.
What Vitamins cause toxicity if ingested in too large amounts are?
A, D, E, K vitamins are fat soluble meaning they accumulate in the fat tissue and can cause toxicity in excess. All others wash out of the body, except B12 and Folate which are stored in the Liver.
Which of the following is caused by mineral deficiency A) beriberi B)goitre C)scurvy D)night blindness?
B) Goitre. Goitre is commonly caused by iodine deficiency, which is a mineral essential for the thyroid gland to produce thyroid hormones. Beriberi is caused by thiamine (vitamin B1) deficiency, scurvy is caused by vitamin C deficiency, and night blindness is caused by vitamin A deficiency.

What benefits are gained from Vitamin B12?
Cells in your stomach secretes something called intrinsic factor. This is needed to take up B12 in your small intestine. From there it is transported to the liver where it is stored, utilized and transported. B12 walks hand in hand with a vitamin called folate or folic acid. B12 is needed for myelination of neurons. That is a covering of the axons that increases the speed of nerve impulses. Folate is needed for proper DNA replication. At last B12 is needed to activate folate. This means that if you have B12 deficiency you will also have folate deficiency. Since folate is vital for DNA replication the cells will divide as usual, but it will be sluggish and incomplete nuclei material. The cells will be bigger. This happens to all cells, but is first seen in cells with low turn-over time such as red blood cells (120 days). Abnormally big red blood cells are called megaloblastic anemia. B12 deficiency will impaire your neural system, most importantly the CNS (central nervous system). This means that a megaloblastic anemia can be cured with folate supplements, but neuronal symptoms can only be cured by B12. If the problem is with the stomach cells secreting the intrinsic factor you will need to bypass that mechanism of the enterohepatic pathway (from the enterocytes in the small intestine to the hepatocytes in the liver). This is done by a shot of B12. If intrinsic factor was the problem, folate deficiency and the anemia will cure itself.
