Everything You Need to Know About Iron
Iron is called a trace mineral, but its effects are mighty. We need it to produce hemoglobin, the oxygen carrier in red blood cells that brings oxygen to the rest of the body. Iron is also needed to produce myoglobin, the oxygen reservoir in the muscle cells.
Iron is notoriously low in the American diet; especially in children one to two years old, and in women ages 12 to 50. Surprisingly, it is also low among athletes, who pack their diets so full of carbohydrates that they tend to omit iron-rich foods.
Inadequate iron stores in the blood cause iron deficiency anemia. Iron is needed for the production of hemoglobin needed for red blood cells. Hemoglobin is important in the transport of oxygen to the body tissues. In the United States, 10-30% of the entire population suffers from iron deficiency anemia. Women are more likely to be anemic because of poor eating habits and blood loss during menstruation. Thus, many women enter pregnancy with reduced iron stores or some level of anemia. According to multiple studies on anemia and pregnancy o...

Typically the human body is able to tell when it has a sufficient amount of iron stored and stops taking it in; this is not what happens
Hemochromatosis is a disease which makes your body absorb all of the iron in food, instead of regulating iron intake. Hemochromatosis “attacks” the entire body, especially the places where most of the iron normally goes: the bloodstream and liver. Some symptoms of this disease are bone and joint discomfort, liver problems, irregular heartbeat, and an unusual bronzing of the skin. Armand Trousseau first described it in 1865 as Diabetes bronze, due to people with diabetes showing the bronze-skin symptom. It was thought to be quite rare at the time. About “⅓ or ¼ of people of Western European descent have th...
Kidney dialysis comes at a price. With chronic kidney disease (CKD), there can be problems with iron depletion. Dialysis slowly depletes a patient of iron. On average, about 5-7 mg of iron is lost in each session. Until recently, the main way doctors tried to compensate for this loss was by adding 100 mg of iron into the bloodstream. This treatment comes with risks of oxidative stress and can cause liver damage. A new drug has recently been in the news and seems to help greatly with this problem. The drug is called Triferic. Triferic mimics the way iron is absorbed into the body naturally. The absorption gradually goes to the body’s bone marrow and helps to maintain levels of hemoglobin. Triferic is still in the trial stages with 3 successful trials done so far. It very well may become an integrated treatment for those with CKD. (Glatter, 2013)
According to the details given in case study, Ms. A has iron deficiency anemia. Iron deficiency anemia is the most common type of anemia. It is a condition where the blood lacks enough red blood cells (Clark, 2008). When there are a low number of red blood cells, it makes transportation of oxygen to parts of the body very difficult. Iron deficiency is type of anemia due to the lack of iron in the body. Without the proper amount of iron in the body, it cannot produce enough hemoglobin and since hemoglobin is the main carrier of oxygen, low levels of it can lead to tiredness and shortness of breath (Copstead, Banasik, 2010).
There are many causes affect to the LBW, one of that is deficiency of micronutrients of pregnant women. Micronutrients such as vitamins and minerals are essential elements for normal body function and growth. During pregnancy, nutrient requirement is increased when developing the fetal, placenta and also important to maternal growth. The impact of micronutrients deficiency on pregnancy is associated with increased maternal morbidity and mortality, abortion, low b...
Iron comes from the Latin word ferrum. From ferrum its symbol became Fe. The atomic number of iron is 26, and its atomic weight is 55.845. Iron is a magnetic, bendable, shiny white metallic element.
After further analysis of case study 1, Ms. A is suffering is the most common type of anemia, Iron Deficiency Anemia. Iron deficiency occurs when red blood cells (RBCs) is lower than normal in the body. The protein is answerable for carrying oxygen in the body’s tissues, which is important for body tissues and muscles to function successfully (Oxygen at altitude,2009). Short of sufficient iron the hemoglobin is not producing enough making someone become anemic, several causes can develop iron deficiency anemia, such as breast breastfeeding, menstruation, blood donation, endurance training, digestive conditions, foods, and caffeinated drinks. And in this case study Ms. A has a bigger cause for iron deficiency anemia that is during mensuration
Proper nutrition is important in maintaining a long and healthy life. Most Americans are rushed due to their busy work schedules, and do not take the time to plan their diets properly. Like me, most Americans are unaware of the importance of eating a healthy diet and consuming too many foods without the proper nutrients. Throughout my life, I have been fortunate. I have not had any major health problems, and have been able to consume most foods without having to worry about gaining weight.
Iron has two forms: heme and nonheme. “Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron. Heme iron, which is formed when iron combines with protoporphyrin IX, contributes about 10% to 15% of total iron intakes in western populations” (National Institute of Health, 2016). The best sources of iron are found in “lean meat and
As we all know oxygen is the main source of life, in the human body Erythrocytes are one of the most important cells, (which transports oxygen to all cells and organs and takes CO2 to be extracted by the lungs), any changed or defect in the DAN or even the shape of it will lead to abnormality to our health. According to Elaine N & Katja H (2008 anatomy and physiology pp 642) Anemia “is a condition in which the blood’s oxygen carrying capacity is too low to support normal metabolism” which has multiple tips like Sickle cell anemia, Aplastic Anemia, Iron-Deficiency anemia and pernicious Anemia.
Iron is a mineral that is found the in hemoglobin of the Red Blood Cells. It facilitates in the transport of oxygen all over the body. Without this mineral, oxygen cannot be carried to its full capacity. 1 out of 10 women and small children have iron deficiencies. Lacking iron causes lethargy and a weakened immune system. Children who do not have an adequate intake of iron put themselves at risk for intellectual developmental problems. However, an iron deficient person is not necessarily anemic. 7.8 million women are iron deficient, while only 3.3 million women are anemic (http://www.mayohealth.org/mayo/9704/iron_def.htm). When the deficiency becomes so severe that the circulating Red Blood Count and the minerals Ht, Hg, and Hem drop below normal, anemia occurs (See Figure 1). The hormone androgen causes men and women to have different normal values of the hemogram (http://www.medstudents.com.br/hemat/hemat4.htm). Low ferritin (iron storage molecule) and high TIBC (tota...
One in every two hundred people with Northern European ancestors are affected with hemochromatosis (Fletcher and Halliday 182). This is one of the most common blood disorders in the United States, and one in every eight to twelve white Americans is a carrier of this disease ("Hemochromatosis,” Cleveland 3). You or someone you know may be a carrier of hemochromatosis. My mom has hemochromatosis. She was diagnosed with the disease in 2007. She had many problems, including joint pains, being tired, and fatigued. Her doctors diagnosed it as many different diseases until a blood sample was taken. It showed that her iron levels were double what they were supposed to be. So my family gave her the nickname, iron women. Hemochromatosis is a common disease, but it has effects on a person’s organs, body, and life.
One of the most common nutrients that meat is known to provide people with is iron. Iron helps the body produce important nutrients like hemoglobin and myoglobin (Sterbenz, 2013). More specifically, meat has heme iron, which is a type of iron found in substances such as meat that produce hemoglobin. Hemoglobin is a type of protein which helps to carry oxygen in the bloodstream. Therefore, it is of no surprise that people who menstruate need more iron in their diets to make up for the blood they lose during the period of menstruation. Also, meat is known to be an excellent source of vitamin B12, another crucial nutrient to humans. Jennifer Preyss reveals that meat offers important B vitamins and that these vitamins, especially B12, are good for the bones, skin, and blood(2012). A fairly straightforward phrase in which the author demonstrates how meat’s nutrients are essential for making one’s body strong. Since vitamin B12 is so good for the blood, it helps keep people, especially women, from being anemic. Both B12 and iron help to make red blood cells (Sterbenz,2013). The red blood cells are major as they are what carries oxygen throughout our bodies. Without the iron or the B12 to make the red blood cells, we would not have anything to carry the oxygen that we breathe through our bloodstream, and no oxygen means we are not breathing and most likely dead. Also, there are many
