In my clinical practice, some of the most common complaints I hear from women are:
“Ma’am, I feel tired all the time, I don’t know why.”
“I get irritated over small things.”
“My hair has suddenly started falling more.”
We often label these symptoms as stress, age-related changes, or hormonal issues and move on. But many times, the cause is very basic :
Iron is a key component of the body’s oxygen transport system.
When iron levels are low, oxygen is not delivered efficiently to body cells, leading to cellular hypoxia.
This is where persistent fatigue begins — the kind that does not improve even after adequate rest.
This fatigue is not simply muscular tiredness. It is actually due to reduced energy production at the cellular level. Every cell in the body contains mitochondria, which generate energy using oxygen. When oxygen supply is reduced, mitochondrial function slows down, and a person feels exhausted even without doing much physical work.
Iron also plays an important role in maintaining the balance of neurotransmitters such as dopamine and serotonin. This is why iron deficiency is often associated with irritability, mood swings, poor concentration, and sometimes unexplained anxiety.
Now let us talk about hair fall.
Hair roots, known as hair follicles, are among the fastest dividing cells in the body. They require a continuous supply of oxygen and nutrients. When iron levels are low, the hair growth cycle shifts prematurely from the anagen phase to the telogen phase, leading to hair shedding from the entire scalp at once, a condition known as diffuse hair fall.
Many women say, “My reports are normal.”
This is usually because only hemoglobin levels are checked. However, the true indicator of iron stores in the body is ferritin. Low ferritin means that the body’s iron reserves are getting depleted, even if hemoglobin levels still appear normal.
Iron deficiency is not a sudden condition. It develops slowly, and many people, especially women, continue to tolerate it considering it “normal.” Therefore, persistent fatigue, mood changes, and continuous hair fall are signals that you should consult your doctor and get the necessary investigations done.
