Janet- IRON Def. An
Janet- Iron Defiency Anema
Question | Answer |
---|---|
Iron deficiency anemia | one of the most common chronic hematologic disorders, is found in up to 30% of worlds population. In US 5-10% of ppl over 45 have this problem. |
Those most susceptible to Iron deficiency anemia are | very young, those on poor diets, and women in their reporductive years. |
In adult male how many mg of iron is lost per day and how? | 1 mg per day through daily feces, sweat and urine |
In normal menstruting women loose how much iron per day? | 1.5 mg |
The median total iron loss with pregnancy is about | 500 mg or almost 2 mg/day over the 280 days of gestation. |
Iron deficiency anemia may develop from | inadequate dietary intake, malabsorbtion, blood loss, or hemolysis |
hemolysis is | the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid |
Dietary Iron is often adequate in | men and older women, but maybe inadequate in pregnant or menstrating women. |
Malabsorption of iron may occur after certain types of: | gastrointestinal (GI) surgery and in malabsorbtion syndromes. |
duodenum | is a hollow jointed tube connecting the stomach to the jejunum. Iron absorbtion occurs here |
2ml of whole blood contains: | 1 mg of iron |
Major sources of chronic blood loss are | GI and genitorinary (GU) systems. |
GI bleeding is often not apparent and there for | may exist for a long time before the problem is identified. |
Loss of 50 to 75 ml of blood from the upper GI track are required for the | stools to appear black |
Black color in stool represents: | the iron in the RBC |
Common causes of GI blood are | peptic ulcer, gastritis, esophagitis, diverticuli, hemorrhoids, and neoplasia |
Gu blood loss occurs mainly from | menstrual blood loss |
Monthly, mensrtual blood loss is about | 45 ml and causes about 22 mg of iron loss. |
Post menopausal bleeding | CAN contribute to anemia in some women |
Pregnancy contributes to iron deficiency because of the diversion of iron to the: | fetus from erythropoiesis, blood loss at delivery, and lactation |
erythropoiesis | is the process by which red blood cells (erythrocytes) are produced |
dialysis may induce iron deficiency anema also, because of the | blood lost in dailysis equipment and frequent blood sampling |
iron deficiency anema | is often free of sings and symptoms at first |
Common findings with iron deficiency anema | most common is pallor, second most common is glossitis and the thrird is cheilitis |
glossitis is | inflammation of the tongue |
cheilitis is | inflammation of the lips |
Pallor is | pale color of skin |
Other signs and symptoms of iron deficiency anema | headache, paresthesias abd a burning sensation of the tongue |
Endoscopy and colonoscopy are used to detect | GI bleeding |
Bone marrow biopsy tests can be done if | other tests are inconclusive |
In Collabrative care of iron deficiency anema is to | treat the underlining disease such as malnutrition, alcoholism |
Iron is absorbed best from the | duodenum and proximal jejunum |
enteric- coated or sustained release capsules | are NOT advised, they are counter productive because they release further in the GI track |
Daily dose of iron should be | 150-200 mg of elemental iron |
iron is best taken with | something acidic like Orange juice |
liquid iron should be diluted and ingested through a straw because: | it can stain the patients teeth |
Common GI side affects from iron administration are: | heartburn, constipation and diarrhea |
Sometimes parenteral use of iron is needed, this would be for | malabsorbtion, intolerance of oral iron, a need for iron beyond oral limita, or poor patient compliance om taking oral preparations |
