Iron deficiency can lead to a decrease in the production of hemoglobin, resulting in reduced oxygen flow to the skin, causing it to appear pale or even yellowish.

Along with fatigue, weakness and a general feeling of weakness or lethargy are common symptoms of iron deficiency due to the decreased oxygen supply to muscles and tissues.

When your body lacks iron, it struggles to produce enough hemoglobin to transport oxygen efficiently, leading to shortness of breath even with mild exertion.
6.
Inadequate oxygen supply to the brain due to iron deficiency can result in headaches, including migraines, and may also cause dizziness or lightheadedness.

Reduced circulation of oxygen-rich blood can make your extremities, such as hands and feet, feel colder than usual, as there is less warmth being generated by the body's cells.

Iron deficiency can lead to brittle, spoon-shaped nails that may develop ridges or become concave in shape. This condition is known as koilonychia.

A lack of iron can affect your sense of taste and smell, leading to a reduced appetite and changes in eating habits.
