Other symptoms include poor appetite and increased incidence and duration of colds and infections. Many of these symptoms are also common to over-training, so misdiagnosis is common.

The only sure way to diagnose a deficiency is a blood test to determine iron status. If you experience any of the symptoms above, and you are in one of the higher risk categories, you should visit your healthcare provider for lab work.

If your healthcare provider confirms iron deficiency , she will recommend an increase in your dietary iron intake. If your deficiency is severe, you may need supplements. Never use iron supplements unless under the supervision of your healthcare provider, as too much iron can cause irreversible damage and a higher risk of cancer and heart disease.

The RDA for women and teenagers is 15 milligrams per day. Men should consume 10 mg. Endurance athletes may need slightly more. You can get iron in both animal and plant foods, but the iron in animal sources has an absorption rate of about 20 to 30 percent, while it reaches up to 10 percent for plants.

You can also increase the amount of iron in foods you eat by cooking with a cast iron skillet especially if cooking acidic foods. Iron absorption from any foods, whether plant or animal, is decreased if they are accompanied at meals by caffeine.

However, adding fruit citrus fruit in particular , to meals enhances iron absorption. The best sources of iron in the diet include: Lean red meat, iron-fortified breakfast cereal, nuts, and legumes, combined these with foods high in vitamin C.

The decision to start iron supplementation in ID should be shared between the athlete, physician, and potentially, a dietician. Iron supplementation without knowing iron levels is not recommended. Iron is best absorbed in the form of food, as opposed to iron supplements, so increasing the intake of iron-rich foods is important to treating both ID and IDA.

Iron-rich foods include animal protein such as red meat, chicken, and fish, as well as non-animal sources, including iron-enriched cereals and pastas, beans, and dark-green leafy vegetables. Iron supplement absorption is improved with vitamin C supplementation.

Orange juice without calcium is a great option to take with the supplement. Iron supplements should not be taken with milk, coffee or calcium tablets, as these can reduce the absorption of iron. Finally, iron supplements can cause constipation, so increasing dietary fiber intake and considering a fiber supplement is important.

Prevention Eating a healthy diet with foods rich in iron is a good way to help maintain normal iron stores in the body. As meat is a good source of iron, athletes who adhere to a vegetarian or vegan diet should be particularly careful to ensure adequate dietary iron consumption.

One main reason irron that is the blood lost Athletes and iron deficiency a woman's monthly period. When iron deficiency becomes severe, it can result in anemia, a condition in which the body has a shortage of red blood cells. Goolsby, MDMedical Director of the Women's Sports Medicine Center at HSS. Iron is a key part of the molecules hemoglobin and myoglobin, which carry oxygen throughout the body and deliver it to the muscles. Iron is stored in many parts of the body, including the liver, bone marrow and muscle.

Athletes and iron deficiency -

The mechanical force of a footstrike during endurance running, for example, can increase the destruction of red blood cells in the feet, leading to a shorter red blood cell life span.

Female athletes are at even higher risk for iron deficiency as compared to males due to monthly blood loss associated with menstruation. Athletes may also be at risk for iron deficiency due to insufficient dietary iron intake.

Remember, the body is not very effective at absorbing dietary iron. Those following a strict vegetarian or vegan diet can be at even higher risk for iron deficiency due to the decreased absorption of non-heme iron found in plants and fortified foods.

Because iron is necessary for oxygen transport and energy metabolism, both of which are critical for fueling aerobic exercise, endurance athletes can experience a decline in exercise capacity and VO2 max, the maximal amount of oxygen the body can use, with iron deficiency.

As iron deficiency becomes more severe, the body cannot make a sufficient number of red blood cells and anemia, meaning low red blood cells, develops. Athletes with iron deficiency anemia will generally have more pronounced symptoms than those with iron deficiency alone.

A craving for ice chips is actually pretty specific to iron deficiency, so any athletes out there who find themselves wanting to eat a lot of ice should definitely have their iron levels checked.

Iron deficiency is diagnosed through blood tests. The most useful of the typical iron study panel is ferritin, which is a marker of iron stores. In the sports nutrition community, there is no clear ferritin goal for athletes. If a ferritin is dropping significantly during the course of a training cycle, this can also be indicative of developing iron deficiency and the need to intervene, even if the ferritin is within what is generally considered a normal range.

It is also worth mentioning that ferritin levels can quickly increase when the body is under stress so results may be falsely high during periods of active infection or inflammation. The other traditional iron panel tests can be useful in distinguishing iron deficiency from poor iron utilization states.

A complete blood count CBC measures the levels of red blood cell in the body and determines whether or not someone is anemic. Markers of red blood cells in a CBC are hemoglobin and hematocrit.

Of note, iron deficiency is only one of the many causes of anemia. Consultation with a sports dietitian is recommended for athletes with iron deficiency.

A sports dietitian can perform a thorough dietary review and make recommendations for ways to increase iron intake. Replenishing iron levels through dietary means is always preferable to taking an iron supplement.

For some, iron supplementation through oral means pill or liquid may be necessary. Oral iron comes in many formulations that are generally equally effective as long as taken regularly. Milk, coffee, and tea can interfere with iron absorption so should not be consumed along with the iron supplement.

Unfortunately, oral iron can be difficult to tolerate due to side effects. Anecdotally, sports dietitians our clinic has worked with find that a specific iron product called Blood Builder is much better tolerated than standard iron supplements, though there is no directed scientific evidence to back this up.

It is NEVER advised to make a self-diagnosis of iron deficiency. If an athlete is concerned that they might be iron deficient, they should get blood tests to confirm the diagnosis. Taking iron supplements in the absence of iron deficiency can lead to iron overload, which is very dangerous.

There are also certain people that are genetically hardwired to absorb more iron and are at risk of iron overload even in the absence of high iron intake.

Iron deficiency in athletes, particularly of the endurance variety, is common. Increasing iron in the diet is an important step in avoiding iron deficiency.

Even so, our bodies only absorb a small portion of the iron we eat. Working with a sports dietitian can help an athlete find ways to increase dietary iron intake and absorption. Iron deficiency can make an athlete feel exhausted and decrease exercise capacity, but is easy to diagnose and generally not complicated to treat.

If an athlete ever sees frank blood in their urine or stool, they should seek medical attention right away for a thorough evaluation. This can be very anxiety provoking in those unaware of this side effect as black stool is usually an indication that there is blood in the stool and may signal a GI bleed.

Iron levels in the body can be low for reasons such as a diet deficient in iron, inadequate iron absorption in the stomach and intestines, or by loss of iron, which is a common cause in menstruating women.

Iron deficiency ID is the result of low iron stores. Occasionally, iron levels may be low enough to cause anemia, which is known as iron deficiency anemia IDA. True anemia may have negative effects on immune function, cognitive abilities, and even athletic performance.

This is particularly concerning to endurance athletes. A sports medicine physician will be aware of the association between low iron levels and decreased athletic performance, and will perform a thorough history and physical exam. Lab tests may be ordered, and are particularly important in assessing iron stores in the body.

These include tests getting the level of hemoglobin, hematocrit, ferritin, and iron, among others. Routine screening for ID and IDA in female athletes and male endurance athletes is often recommended.

An athlete with low ferritin and iron levels, and normal hemoglobin and hematocrit, is considered to have ID, but not IDA. If the athlete also has low hemoglobin and hematocrit levels, then he or she has IDA. For athletes with IDA, the evidence is clear that a daily oral iron supplement is beneficial in improving athletic performance.

However, there is controversy about whether iron supplementation in athletes with ID alone is helpful. The decision to start iron supplementation in ID should be shared between the athlete, physician, and potentially, a dietician.

Iron supplementation without knowing iron levels is not recommended. Iron is best absorbed in the form of food, as opposed to iron supplements, so increasing the intake of iron-rich foods is important to treating both ID and IDA.

Athletes, particularly female athletes participating in endurance sport, are at increased risk of compromised iron status due to heightened iron losses through menstruation and exercise-induced mechanisms associated with endurance activity. However, this approach has been criticised because of the side effects and increased risk of iron toxicity associated with the use of supplements. Thus, more recently there has been a growing interest in using dietary modification rather than the use of supplements to improve iron status of athletes.
