3. Pale skin
Hemoglobin usually gives the skin a rosy color and healthy glow, hence low levels of hemoglobin cause the skin to become pale. The paleness can be localized (involving one limb or body part only) or generalized (all over the body.)
Iron is an essential element for the production of blood in the body. Most of the body’s iron is found in the red blood cells, hence less iron means less red blood cells are produced. This leads to the paleness of the skin.
When red blood cells have low iron levels, they usually become smaller and paler in the center, hence the skin also becomes paler. This affects all skin tones, though it is easier to detect in people with lighter complexions. Despite the color of your skin, if the area inside your bottom eyelid or your fingernails seems lighter than normal then that could be a sign of iron deficiency in your body.
Since iron, mostly found in hemoglobin, helps in the transport of oxygen from the lungs to all the body parts, an iron deficiency means less oxygen is transported all over the body, resulting in pale skin.
Skin paleness is considered an emergency when it is accompanied by other symptoms such as fainting, fever, abdominal pain and bleeding from the rectum. If these symptoms occur, then one should visit a doctor immediately. Pale skin on its own should not be ignored, as it may be a sign of anemia due to low iron levels, hence low blood levels, in the body. One should consume iron-rich foods such as spinach, and if the paleness does not go away, they should consult a doctor, as it could be a precursor to more serious problems in the body. Paleness accompanied by fatigue and mild shortness of breath are indicators of an iron deficiency in the body.
