Iron Deficiency Anemia Sara Merley Nutrition – Professor Brown
Definition • Iron deficiency anemia is caused from a shortness of iron in the body. “[Iron] is a component of hemoglobin (which transports oxygen within red blood cells) and some enzymes” (Hoehn, Marieb). The iron-rich protein, hemoglobin, is essential to the transportation of oxygen to the body’s tissues. • http://www.hematology.org/Patients/Blood-Disorders/Anemia/5225.aspx • In America, there are over 3 million people effected by anemia.
Heme vs. Non-Heme HEME IRON – “Iron provided from animal tissues in the form of hemoglobin and myoglobin. Approximately 40% of the iron in meat is heme iron; it is readily absorbed” (Wardlaw). NON-HEME IRON – “Iron provided from plant sources and animal tissues other than in the forms of hemoglobin and myoglobin. Non-heme iron is less efficiently absorbed than heme iron; absorption is closely dependent on body needs” (Wardlaw).
Symptoms of IDA • Paleness or “Sallow Skin” • Extreme fatigue / lack of energy • Chest pain • Shortness of breath • Headaches • Feeling weak • Rapid heart rate • Sore or smooth tongue
Poor appetite / unusual cravings for non-nutritional substances such as ice or clay. • An uncomfortable crawling feeling in your legs • Cold hands and feet • Irritability • Brittle Nails
Common Causation of Iron-Deficiency Anemia • 1) Most predominately, lack of iron within the food one consumes. • 2) Blood Loss; most prevalent in women because of menstruation. • 3) Pregnancy; because of the increased blood volume and source of hemoglobin as the fetus grows. • 4) Inability to absorb the iron consumed into one’s bloodstream.
Population Distribution Because iron-deficiency anemia can simply be caused by lack of iron in the diet, it can happen at any time in a person’s life. There are factors in which it appears to be more common however: • Women with heavy menstrual bleeding. • Women whom are pregnant or breastfeeding with recently given birth. • People with a gastrointestinal disease such as Celiac or Crohn’s disease. • Vegetarians and Vegans.
Other Causes of IDA: • Hemorrhoids • Frequent blood donations • Intravascular Hemolysis (condition where RBC break down in the blood stream then causing a release of excess iron into the urine). • Stomach / Bowel Ulcers
Lack of Iron in One’s Diet;How much is enough? • Women 19-50 years old need to consume 18 milligrams per day. Men (all ages) and women over 50 only have to consume 8 milligrams. • Diet is one of the most prevalent ways of becoming iron-deficient anemic. Especially in women 19-50 whom do not consume a great deal of iron-rich foods.
Diagnosed, how much is enough? • In patients diagnosed with iron-deficiency anemia it is recommended that they consume 2 – 5 milligrams per kilogram of body weight per day. • Still is highly advised to discuss the proper amount with one’s doctor.
Diagnosis Process • IDA is diagnosed through a blood test of a complete blood count; when someone is diagnosed the test results usually show: • Low hemoglobin and hematocrit • Low mean cellular volume • Low ferritin • Low serum iron • High transferrin • Low iron saturation
Iron-Rich Foods • Clams (3 ounces) 14 milligrams • Spinach (1 cup) 6.4 milligrams • Kidney Beans (1 cup) 5.3 milligrams • Pot Roast (4 ounces) 3.9 milligrams • Sirloin Steak (4 ounces) 3.8 milligrams • Garbanzo Beans (1/2 cup) 2.4 milligrams • Baked Potato (average 1) 1.7 milligrams
More general food overview • MEAT: beef or lamb; especially organs meats and dark meats. • FISH: primarily shellfish. • LEAFY GREENS: broccoli and turnip greens. • LEGUMES: Lima beans, peas, and black-eyed peas. • IRON-ENRICHED: pastas, grains, and cereals.
More Iron • Cook with a cast-iron pan; some of the iron will be absorbed into the food. IRON supplement; In my opinion, the best iron supplement is “Slow FE” since taking an iron supplement can cause constipation.
Absorption of Iron Vitamin C is extremely helpful to the absorption of iron. As one consumes iron, vitamin C will wrap around the iron ions protecting it against destruction from stomach acid; so that then the iron may reach the small intestine where it is absorbed in the duodenum and first part of the jejunum. Interesting fact: children are encouraged not to drink more than 16 to 24 ounces of cow’s milk per day because it can in turn, inhibit the absorption of iron.
Other treatment • Red blood cell transfusions – are performed for patients with severe iron-deficiency anemia. For example, severe bleeding, chest pain, and weakness. • Intravenous Iron – this is used for iron-deficient patients whom, have the tendency to not absorb iron well in the gastrointestinal tract, have extreme blood loss, are receiving a hormone that increases blood loss, or cannot tolerate taking an iron supplement.
