Janet- IRON Def. An

Janet- Iron Defiency Anema

QuestionAnswer
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
