Homeopathic remedies for allergies deficiency anemia is diminished red deficifncy cell production due to low iron stores in the body.
It is the most common nutritional disorder worldwide and accounts for approximately one-half of anemia cases. Diagnosis of iron deficiency anemia requires laboratory-confirmed evidence of anemia, as well as evidence of Iron deficiency anemia defciency stores.

The following diagnostic approach is recommended in deficiiency with anemia and is outlined in Figure naemia. Ferritin reflects iron stores and is the most Iron deficiency anemia test to diagnose iron deficiency anemia.
In Healthy approaches to drinking with chronic inflammation, iron deficiency anemia is likely when the ferritin level is less than 50 ng per mL In patients with no inflammatory states and in Dietary modifications for diabetes the ferritin level is indeterminate 31 to 99 ng per mL [ Values consistent with iron deficiency include a low serum iron level, low transferrin saturation, and a high deficienccy iron-binding capacity.

Patients with deficiencj deficiency anemia are deficlency asymptomatic and have seficiency findings on examination. Further evaluation should be based on risk factors Figure deficienncy.
Excessive menstruation is a common cause of iron deficiency anemia in premenopausal women in developed countries; however, a GI source particularly erosive lesions in the stomach or esophagus is present in 6 to 30 percent of cases.
Excessive or irregular menstrual bleeding affects 9 to 14 percent of all women and can lead to varying degrees of iron deficiency anemia. Initial evaluation includes a history, physical examination, and pregnancy and thyroid-stimulating hormone tests. An endometrial biopsy should be considered in women 35 years and younger who have conditions that could lead to unopposed estrogen exposure, in women older than 35 years who have suspected anovulatory bleeding, and in women with abnormal uterine bleeding that does not respond to medical therapy.
In men and postmenopausal women, GI sources of bleeding should be excluded. Current recommendations support upper and lower endoscopy; however, there are no clear guidelines about which procedure should be performed first or if the second procedure is necessary if a source is found on the first study.
In patients in whom endoscopy may be contraindicated because of procedural risk, radiographic imaging may offer sufficient screening. The sensitivity of computed tomographic colonography for lesions larger than 1 cm is greater than 90 percent.
If initial endoscopy findings are negative and patients with iron deficiency anemia do not respond to iron therapy, repeat upper and lower endoscopy may be justified. In some instances, lesions may not be detected on initial examination e.
Additional evaluation of the small intestine is not necessary unless there is inadequate response to iron therapy, the patient is transfusion dependent, or fecal occult blood testing suggests that the patient has had obscure GI bleeding with the source undiscovered on initial or repeat endoscopy.
This test is a second-line technique for evaluating the small bowel because it is complicated by the level of sedation and duration of procedure. Patients with an underlying condition that causes iron deficiency anemia should be treated or referred to a subspecialist e.
The dosage of elemental iron required to treat iron deficiency anemia in adults is mg per day for three months; the dosage for children is 3 mg per kg per day, up to 60 mg per day. Adherence to oral iron therapy can be a barrier to treatment because of GI adverse effects such as epigastric discomfort, nausea, diarrhea, and constipation.
These effects may be reduced when iron is taken with meals, but absorption may decrease by 40 percent. Parenteral therapy may be used in patients who cannot tolerate or absorb oral preparations, such as those who have undergone gastrectomy, gastrojejunostomy, bariatric surgery, or other small bowel surgeries.
The most common indications for intravenous therapy include GI effects, worsening symptoms of inflammatory bowel disease, unresolved bleeding, renal failure—induced anemia treated with erythropoietin, and insufficient absorption in patients with celiac disease.
Parenteral treatment options are outlined in Table 3. A newer formulation, ferumoxytol, can be given over five minutes and supplies mg of elemental iron per infusion, allowing for greater amounts of iron in fewer infusions compared with iron sucrose.
There are no standard recommendations for follow-up after initiating therapy for iron deficiency anemia; however, one suggested course is to recheck complete blood counts every three months for one year.
If hemoglobin and red blood cell indices remain normal, one additional complete blood count should be obtained 12 months later. A more practical approach is to recheck the patient periodically; no further follow-up is necessary if the patient is asymptomatic and the hematocrit level remains normal.
There is no universally accepted threshold for transfusing packed red blood cells in patients with iron deficiency anemia. Guidelines often specify certain hemoglobin values as indications to transfuse, but the patient's clinical condition and symptoms are an essential part of deciding whether to transfuse.

Blood contains iron within red blood cells. So if you lose blood, you lose some iron. Women with heavy periods are at risk of iron deficiency anemia because they lose blood during menstruation. Slow, chronic blood loss within the body — such as from a peptic ulcer, a hiatal hernia, a colon polyp or colorectal cancer — can cause iron deficiency anemia. Gastrointestinal bleeding can result from regular use of some over-the-counter pain relievers, especially aspirin. A lack of iron in your diet. Your body regularly gets iron from the foods you eat. If you consume too little iron, over time your body can become iron deficient. Examples of iron-rich foods include meat, eggs, leafy green vegetables and iron-fortified foods. For proper growth and development, infants and children need iron from their diets, too. An inability to absorb iron. Iron from food is absorbed into your bloodstream in your small intestine. An intestinal disorder, such as celiac disease, which affects your intestine's ability to absorb nutrients from digested food, can lead to iron deficiency anemia. If part of your small intestine has been bypassed or removed surgically, that may affect your ability to absorb iron and other nutrients. Without iron supplementation, iron deficiency anemia occurs in many pregnant women because their iron stores need to serve their own increased blood volume as well as be a source of hemoglobin for the growing fetus. These groups of people may have an increased risk of iron deficiency anemia: Women. Because women lose blood during menstruation, women in general are at greater risk of iron deficiency anemia. Infants and children. Infants, especially those who were low birth weight or born prematurely, who don't get enough iron from breast milk or formula may be at risk of iron deficiency. Children need extra iron during growth spurts. If your child isn't eating a healthy, varied diet, he or she may be at risk of anemia. People who don't eat meat may have a greater risk of iron deficiency anemia if they don't eat other iron-rich foods. Frequent blood donors. People who routinely donate blood may have an increased risk of iron deficiency anemia since blood donation can deplete iron stores. Low hemoglobin related to blood donation may be a temporary problem remedied by eating more iron-rich foods. If you're told that you can't donate blood because of low hemoglobin, ask your doctor whether you should be concerned. However, left untreated, iron deficiency anemia can become severe and lead to health problems, including the following: Heart problems. Iron deficiency anemia may lead to a rapid or irregular heartbeat. Your heart must pump more blood to compensate for the lack of oxygen carried in your blood when you're anemic. This can lead to an enlarged heart or heart failure. Problems during pregnancy. In pregnant women, severe iron deficiency anemia has been linked to premature births and low birth weight babies. But the condition is preventable in pregnant women who receive iron supplements as part of their prenatal care. Growth problems. In infants and children, severe iron deficiency can lead to anemia as well as delayed growth and development. Additionally, iron deficiency anemia is associated with an increased susceptibility to infections. You can reduce your risk of iron deficiency anemia by choosing iron-rich foods. Choose iron-rich foods Foods rich in iron include: Red meat, pork and poultry Seafood Beans Dark green leafy vegetables, such as spinach Dried fruit, such as raisins and apricots Iron-fortified cereals, breads and pastas Peas Your body absorbs more iron from meat than it does from other sources. Choose foods containing vitamin C to enhance iron absorption You can enhance your body's absorption of iron by drinking citrus juice or eating other foods rich in vitamin C at the same time that you eat high-iron foods. Vitamin C is also found in: Broccoli Grapefruit Kiwi Leafy greens Melons Oranges Peppers Strawberries Tangerines Tomatoes.

Treatment with iron supplements usually makes the anemia better. When symptoms do happen, a child might: look pale seem moody be very tired get tired quickly from exercise feel dizzy or lightheaded have a fast heartbeat have developmental delays and behavioral problems want to eat ice or non-food items called pica What Causes Iron-Deficiency Anemia? Iron-deficiency anemia can happen when: There's a problem with how the body absorbs iron such as in celiac disease. Someone has blood loss from an injury, heavy menstrual periods , or bleeding inside the intestines. Someone doesn't get enough iron in the diet. This can happen in: children who drink too much cow's milk, and babies given cow's milk before they're 1 year old vegetarians because they don't eat meat, a source of iron breastfed babies who don't get iron supplements babies given formula with low iron babies who were born early or small who may need more iron than formula or breast milk contains How Is Iron-Deficiency Anemia Diagnosed? Doctors usually can diagnose iron-deficiency anemia by: asking questions about symptoms asking about the diet finding out about the patient's medical history doing a physical exam doing blood tests to: look at the red blood cells with a microscope check the amount of hemoglobin and iron in the blood check how fast new RBCs are being made do other blood tests to rule out other types of anemia How Is Iron-Deficiency Anemia Treated? To help iron get absorbed into the body: Avoid taking iron with antacids, milk, or tea because these interfere with the body's ability to absorb iron. Take iron before eating unless this causes an upset stomach. When iron-deficiency anemia is caused by something other than a lack of iron in the diet, treatment also may include: treatments to reduce bleeding in heavy menstrual periods reducing the amount of cow's milk in the diet treating an underlying disease How Can Parents Help? If your child has iron-deficiency anemia: Make sure your child takes the iron supplements exactly as prescribed. Include iron-rich foods in the family's diet. Good sources of iron include: iron-fortified cereals lean meat, poultry, and fish tofu egg yolks beans raisins Serve fruits and vegetables high in vitamin C or a glass of orange juice at mealtimes. This helps the iron get absorbed. Talk to a dietitian or your doctor if your child is a vegetarian. They can recommend foods to help your child get enough iron. To help prevent iron-deficiency anemia in young children: Don't give cow's milk to babies under 1 year old. Limit cow's milk in kids over 1 year old to less than 2 cups of milk a day. |

Causes Red blood cells bring oxygen to the body's tissues. Iron deficiency anemia develops when your body's iron stores run low. This can occur because: You lose more blood cells and iron than your body can replace Your body does not absorb iron well Your body is able to absorb iron, but you are not eating enough foods that contain iron Your body needs more iron than normal such as if you are pregnant or breastfeeding Bleeding can cause iron loss.
Common causes of bleeding are: Heavy, long, or frequent menstrual periods Cancer in the esophagus, stomach, small bowel, or colon Esophageal varices , often from cirrhosis The use of aspirin, ibuprofen, or arthritis medicines for a long time, which can cause gastrointestinal bleeding Peptic ulcer disease Your body may not absorb enough iron in your diet due to: Celiac disease Crohn disease Gastric bypass surgery Taking too many antacids or too much of the antibiotic tetracycline You may not get enough iron in your diet if: You are a strict vegetarian You do not eat enough foods that contain iron.
Symptoms You may have no symptoms if the anemia is mild. Most of the time, symptoms are mild at first and develop slowly. Symptoms may include: Feeling weak or tired more often than usual, or with exercise Headaches Dizziness Palpitations Problems concentrating or thinking As the anemia gets worse, symptoms may include: Brittle nails Blue color to the whites of the eye Desire to eat ice or other non-food things pica Feeling lightheaded when you stand up Pale skin color Shortness of breath Sore or inflamed tongue Mouth ulcers Uncontrolled movement of legs during sleep Hair loss Symptoms of the conditions associated with bleeding that cause iron deficiency anemia include: Dark, tar-colored stools or blood in the stool Heavy menstrual bleeding Pain in the upper belly from ulcers.
Exams and Tests To diagnose anemia, your health care provider may order these blood tests: Complete blood count CBC Reticulocyte count To check iron levels, your provider may order: Serum iron level Iron binding capacity TIBC in the blood Serum ferritin Bone marrow biopsy if the diagnosis is not clear To check for causes of blood loss, your provider may order: Colonoscopy Fecal occult blood test Upper endoscopy Tests to detect sources of blood loss in the urinary tract or uterus.
Treatment Treatment may include taking iron supplements and eating iron-rich foods. Iron supplements are mostly well tolerated, but may cause: Nausea Vomiting Constipation Iron-rich foods include: Chicken and turkey Dried lentils, peas, and beans Fish Meats liver is the highest source Soybeans, baked beans, chickpeas Whole-grain bread Other sources include: Oatmeal Raisins, prunes, apricots, and peanuts Spinach, kale, and other greens Vitamin C helps your body to absorb iron.
Good sources of vitamin C are: Oranges Grapefruits Kiwi Strawberries Broccoli Tomatoes. Outlook Prognosis With treatment, the outcome is likely to be good, but it does depend on the cause. When to Contact a Medical Professional Contact your provider if: You have symptoms of iron deficiency You notice blood or a black tar-appearance in your stool.

In the most severe cases, a red blood cell transfusion or intravenous iron can replace iron and blood loss quickly. When caused by inadequate iron intake, iron-deficiency anemia can be prevented by eating a diet high in iron-rich foods and vitamin C.
Mothers should feed their babies breast milk or iron-fortified infant formula. Potential causes include not eating enough iron-rich foods, blood loss due to menstruation, and inability to absorb iron. If you suspect you have an iron deficiency, see a doctor.
They can diagnose anemia with blood tests. You could end up with too much iron in your blood which can cause other health conditions, including constipation and even liver damage.

The evaluation should begin with a thorough history and physical examination to help identify the cause of iron deficiency. The history should focus on potential etiologies and may include questions about diet, gastrointestinal GI symptoms, history of pica or pagophagia i.
Patients with iron deficiency anemia are often asymptomatic and have limited findings on examination. Further evaluation should be based on risk factors Figure 2. Excessive menstruation is a common cause of iron deficiency anemia in premenopausal women in developed countries; however, a GI source particularly erosive lesions in the stomach or esophagus is present in 6 to 30 percent of cases.
Excessive or irregular menstrual bleeding affects 9 to 14 percent of all women and can lead to varying degrees of iron deficiency anemia. Initial evaluation includes a history, physical examination, and pregnancy and thyroid-stimulating hormone tests. An endometrial biopsy should be considered in women 35 years and younger who have conditions that could lead to unopposed estrogen exposure, in women older than 35 years who have suspected anovulatory bleeding, and in women with abnormal uterine bleeding that does not respond to medical therapy.

Patients with an underlying condition that causes iron deficiency anemia should be treated or referred to a subspecialist e. The dosage of elemental iron required to treat iron deficiency anemia in adults is mg per day for three months; the dosage for children is 3 mg per kg per day, up to 60 mg per day.
Adherence to oral iron therapy can be a barrier to treatment because of GI adverse effects such as epigastric discomfort, nausea, diarrhea, and constipation. These effects may be reduced when iron is taken with meals, but absorption may decrease by 40 percent.
Parenteral therapy may be used in patients who cannot tolerate or absorb oral preparations, such as those who have undergone gastrectomy, gastrojejunostomy, bariatric surgery, or other small bowel surgeries.
The most common indications for intravenous therapy include GI effects, worsening symptoms of inflammatory bowel disease, unresolved bleeding, renal failure—induced anemia treated with erythropoietin, and insufficient absorption in patients with celiac disease.
Parenteral treatment options are outlined in Table 3. A newer formulation, ferumoxytol, can be given over five minutes and supplies mg of elemental iron per infusion, allowing for greater amounts of iron in fewer infusions compared with iron sucrose. There are no standard recommendations for follow-up after initiating therapy for iron deficiency anemia; however, one suggested course is to recheck complete blood counts every three months for one year.
If hemoglobin and red blood cell indices remain normal, one additional complete blood count should be obtained 12 months later.
A more practical approach is to recheck the patient periodically; no further follow-up is necessary if the patient is asymptomatic and the hematocrit level remains normal. There is no universally accepted threshold for transfusing packed red blood cells in patients with iron deficiency anemia.
Guidelines often specify certain hemoglobin values as indications to transfuse, but the patient's clinical condition and symptoms are an essential part of deciding whether to transfuse.
