What Is Iron Deficiency

Iron deficiency is characterized by a reduction in the amount of iron in the body. Iron deficiency anemia is a common problem in the world. It can occur when the amount of iron in the body is too low. In addition to causing fatigue and weakness, iron deficiency anemia increases a person’s risk of developing other health problems.

The following are some of the most serious consequences of iron deficiency:

1. Anemia

The most serious complication of a mineral shortage is anemia. Fatigue, faintness, bodily weakness, headaches, and increased sensitivity to cold temperatures are among the signs of this condition. Low blood pressure, kidney failure, leukemia, muscle spasms, colon cancer, and other health problems can all be caused by it.


2. Lead Toxicity

Iron deficiency can increase the risk of lead poisoning in children. According to a study published in the journal Science of the Total Environment, high iron intake and appropriate iron storage can reduce the risk of lead poisoning in children.

Other issues linked to iron shortage include decreased immunity, pregnancy troubles, and intellectual impairment in children, among others.

Risk of Excessive Iron Consumption

Though iron is essential for our bodies, too much of it can be harmful. The following are some of the side effects of an iron overdose:

1. A Higher Chance Of Cardiovascular Diseases

too much iron may cause cardiovascular problems

According to a study conducted by Indiana University, heme iron, which is abundant in red meat, can increase the risk of coronary heart disease by 57%. According to the study, non-heme iron does not affect the risk of heart disease. As a result, it’s critical to keep your iron intake from heme sources to a minimum.

2. High Cancer Incidence

Cancers such as colorectal, colon, and liver cancer can all be exacerbated by a high iron intake. A study published in Cancer Epidemiology, Biomarkers, and Prevention discovered a link between iron and colorectal cancer risk.

3. The Presence Of Gastrointestinal Issues

Iron supplementation is recommended by doctors all around the world for patients who are iron deficient. Nausea, diarrhea, constipation, and black stools are all possible adverse effects of these supplements  Consult your doctor for advice on how to manage these symptoms.

4. Risk of Neurodegenerative Diseases

Though iron is necessary for enhanced brain function, too much of it can lead to increased oxidative damage in the brain. As a result, it may increase the risk of neurodegenerative illnesses in the elderly, such as Alzheimer’s and Parkinson’s disease.

5. Increased Risk of Type 2 Diabetes

Heme iron is also linked to an increased risk of type 2 diabetes in women, according to a study published by the American Diabetes Association.

6. Increased Risk of  Premature Aging

Iron, according to several authorities, aids in the prevention of premature skin aging. This assertion, on the other hand, could not be further from the truth. According to a study published in Ageing Research Reviews, an excessive amount of iron might enhance the creation of harmful hydroxyl radicals, causing oxidative damage and premature skin aging.


Iron is involved in several vital body processes, including protein metabolization and the creation of red blood cells and enzymes. So, to reap the benefits of iron, you must consume enough of it throughout your diet. Iron-rich meals can help you get a rosy glow, speed wound healing, prevent excessive hair loss, increase appetite, promote muscle and brain health, and support a healthy pregnancy. To avoid iron deficiency anemia and lead toxicity, include foods like tofu, beans, turnips, legumes, lentils, eggs, and dairy products in your diet. It’s crucial to achieve a balance because too much iron might cause health problems.
