what can low iron cause

Low iron can cause a condition known as iron deficiency anemia, which occurs when the body doesnt have enough iron to produce hemoglobin, a substance in red blood cells that allows them to carry oxygen throughout the body. This can lead to a range of symptoms and complications, including fatigue, weakness, pale skin, dizziness, lightheadedness, chest pain, rapid heartbeat, shortness of breath, and unusual cravings for non-food items such as ice, dirt, or paper. If left untreated, iron deficiency anemia can make individuals more susceptible to illness and infection, and in severe cases, it can lead to complications affecting the heart, lungs, and pregnancy, such as premature births and low birth weight babies. The causes of low iron levels can include insufficient dietary intake of iron, chronic blood loss, heavy periods, pregnancy, and conditions that limit the absorption of iron from the diet. Its important to address low iron levels through dietary changes and, if necessary, iron supplementation to prevent the development of iron deficiency anemia and its associated health problems.
