Iron deficiency symptoms can occur when one’s diet does not include an adaquate amount of iron; when there is excessive loss of blood; or when the body has increased its need for iron – such as during pregnancy, breastfeeding and adolescence.

When there is insufficient amount of iron in the body, there will not be enough red blood cells to correctly carry oxygen throughout the body. Insufficient red blood cells in the body is a condition known as anemia, with symptoms that include tiredness and paleness.

Severe anemia can give rise to increased or irregular heart rate as the heart will pump more blood in order to make up for the lack of oxygen. Iron deficiency doesn’t always result in anemia as it can also lead to having a weakened immune system or lethargy and other health problems.
