1. Constant Fatigue
Iron is essential for producing hemoglobin, the protein in red blood cells that carries oxygen throughout the body. When iron levels are low, your muscles and organs receive less oxygen, leaving you feeling tired, weak, and exhausted—even after a full night’s sleep. This is one of the most common symptoms of iron deficiency.

2. Pale Skin
A healthy amount of hemoglobin gives your skin its natural pink or rosy tone. Low iron can reduce hemoglobin levels, making the skin appear pale or washed out. This is often most noticeable on the face, inside the eyelids, gums, and nail beds.

3. Shortness of Breath
If your body cannot transport enough oxygen, even simple activities like climbing stairs or walking may leave you breathless. You may feel like you need to take deeper breaths because your tissues aren’t getting enough oxygen.

4. Frequent Headaches
Iron deficiency can reduce the amount of oxygen reaching the brain, which may cause blood vessels to swell and trigger headaches. Some people also experience migraines or pressure around the forehead.

5. Cold Hands and Feet
People with low iron often have poor circulation because less oxygen-rich blood reaches the body’s extremities. As a result,mouad your hands and feet may feel unusually cold, even in warm environments.
