Iron deficiency is a significant public health problem. At the present time, roughly one-third of the world’s population is afflicted with iron deficiency causes of anemia, and the great risk is being posed concerning the long-term consequences of iron deficiency on neurocognitive development and immune functioning. Iron is an essential nutrient for the normal performance of cellular function and may be found in important proteins and enzymes. More importantly, iron represents an essential factor for the functioning of hemoproteins, especially in oxygen and electron transport. Additionally, iron is primarily presented in the human organism in the forms of hemoglobin, myoglobin, and iron stores. Nevertheless, iron shortage supplies can be regarded as the most widespread iron nutritional deficiency in the world. Normally, the most susceptible are women and children due to their higher needs of diet besides a wide range of food restrictions. This medical condition affects older adults too but the background of the matter and its outcome are both different.
The prevalence of iron deficiency is approximately 4% in most of the population. In the general population, the prevalence of iron deficiency anemia is about 20% to 30% and is around 40% to 70% among pregnant women and children. Some 500 million people suffer from iron deficiency symptoms, and about 50 million people in the United States get medical attention each year for conditions associated with iron deficiency. Iron deficiency anemia remains a very common condition among children. The familiar clinical form of iron deficiency symptoms was described in the medical literature over 300 years ago. Since that time, it has long been regarded as the most common and most severe of all nutritional deficiencies and through extensive clinical study has advanced to be the best understood. The global strategy, though ambitious, was formulated in the year 2001 and aimed at reducing by one-third the prevalence of anemia in women of childbearing age.
Iron is a very vital mineral in the body, but most are not grasping the fact that its deficiency will bring about illnesses or diseases. Most people who develop mild to moderate iron deficiency may become asymptomatic, but then again, this usually goes undetected unless their condition has gotten worse. The inability to finish tasks can be noticed with symptoms related to the exhaustion of energy, as iron can provide the nutrient needed to make red blood cells. These are the blood cells carrying oxygen from the lungs to the body’s tissues. When the body destroys its old red blood cells, it recycles their iron back into the bloodstream. Loss of this iron puts stress on the body to make new red blood cells. Iron deficiency anemia is the most extreme form of iron deficiency. General iron deficiency symptoms include weakness, pale skin, chest pain, frequent infections, brittle nails, headache, dizziness, and shortness of breath. Symptoms may also depend upon an individual’s age and gender. Individuals can also experience the symptoms differently, while the severity of anemia will equally affect the signs. In some individuals, symptoms start to appear once iron levels are below average.
There are various factors that can influence the iron status of an individual, which can generally be classified into dietary, physiological, and pathological factors, according to the interplay of personal variables. From epidemiological investigations, individuals with lower socioeconomic status and risky eating behaviors, such as teenagers and young adults, are the most affected by iron deficiency. However, the presence of different contributing causative factors can impact the actual occurrence of the deficiency. A second potential cause could be the increased requirement for iron, which occurs during times of physiological need such as pregnancy and breastfeeding, and during periods of rapid growth, such as late infancy and adolescence. Physiological requirements of iron thus depend on the interplay of various other factors, such as sex, age, and life conditions, making young females between 12 and 49 years a potential at-risk group, especially during puberty or characterized by suboptimal dietary habits.
Chronic blood loss would be the third main underlying cause. As a result of the blood loss required for childbearing, and other possible conditions related to women’s generative apparatus, women, and particularly pregnant women, have double the iron requirements compared to men. Childbirth and menstruation are essential iron deficiency causes of blood loss, both directly linked to the generative apparatus of the female body; however, different types of chronic or acute pathologies, medications, or emergency care services following trauma or surgery might enhance this loss. As close interactions occur among contributing risk factors from both medical and lifestyle viewpoints, an in-depth analysis of the possible interconnections resulting in iron deficiency is surely of the utmost importance for identifying the potential combinations involved in improving the overall health of the individual.
Iron deficiency treatment aims to alleviate symptoms and treat the underlying cause of the deficiency as much as possible. Taking an iron supplement can aid recovery and provide prompt alleviation of anemia, but other iron deficiency symptoms may take longer to resolve. Often, consumption of a diet with a good source of iron is sufficient to meet daily requirements. Iron supplements can be obtained in a range of formulations over-the-counter at pharmacies and health food stores, including ferrous sulfate, fumarate, gluconate, and polysaccharide-iron complex. Other options include dietary advice and iron infusions, although this option is usually reserved for those who have ongoing blood loss or who cannot tolerate oral iron.
In acute care settings, individuals who are symptomatic, have severe iron deficiency, or those who are unable to tolerate oral iron may be offered intravenous iron therapy. There is a growing body of evidence for the effectiveness and benefits of IV iron therapy among different patient populations, and the safety of IV iron therapy in a range of clinical situations has also been demonstrated. Iron deficiency treatment plans should be determined on an individual basis and will be guided by the underlying cause of deficiency and a person’s iron requirements, aiming to replenish iron stores over time as well as treat the cause of deficiency. In order to effectively address iron deficiency, a range of interventions at an individual and population level may be beneficial. Evidence suggests that a comprehensive, tailored iron deficiency treatment plan is more likely to have a greater impact on iron deficiency symptoms and overall quality of life. In other words, it is better to use a combination of treatments that include measures to stop or decrease any bleeding, and, if the body’s stores are low, increase or reload them. Tailored treatment plans for any underlying iron deficiency causes by a healthcare professional that take into account the duration, extent, and cause of iron deficiency will best assist in successful recovery. An education program highlighted the important contribution the school environment can make to improving students’ awareness, attitudes, and practices with respect to nutrition and lifelong wellness.
Participants involved in this trial reported that improved understanding of the iron content in food had assisted in iron deficiency prevention. Replacement of the lacking iron in the body simply requires more iron, as long as the loss or cause of low iron has been addressed. However, taking higher than required iron supplements if there are no problems or deficiencies of iron in the body is not recommended long term, as high iron stores can be harmful. The body has mechanisms that can limit iron excess. The exception is increasing iron when there has been a history of excessive or frequent blood loss, as this loss cannot compensate and return iron stores to normal over time. As such, these steps towards restoring iron in the body may be done over the course of a few months and involve: increasing dietary changes, increasing foods with a good source of iron, taking an iron supplement, enjoying foods that help absorb and maximize absorption of iron, including Vitamin C. If needed, include meat, seafood, or alternatives higher in iron. If iron stores are low, aim for 60 to 100 mg of elemental iron daily. Therapeutic doses of iron are different from preventative or daily doses of iron. Follow-up treatment: More frequent checks may be needed if iron levels are slow to increase, or if the doctor has recommended monitoring.
