When iron levels are low, the body cannot produce enough hemoglobin, which means that tissues and organs do not receive enough oxygen. This can lead to fatigue, weakness, and a general feeling of being run down.
Other symptoms of iron deficiency can include pale skin, shortness of breath, headache, dizziness, and brittle nails. In severe cases, iron deficiency can lead to iron deficiency anemia, a condition in which the body does not have enough red blood cells to carry oxygen to the tissues.
If you are experiencing persistent fatigue and weakness, it is important to see your healthcare provider to determine the cause. If iron deficiency is suspected, your healthcare provider may order blood tests to check your iron levels.
To prevent iron deficiency, consume iron-rich foods on a regular basis, such as lean meat, poultry, fish, beans, lentils, and fortified cereals. Pair iron-rich foods with vitamin C-rich foods to enhance iron absorption, and avoid consuming iron absorption inhibitors, such as tea and coffee, with meals.
