Anemia is the most common alteration in blood hemoglobin levels. It features a reduction of hemoglobin below 13.5 grams per deciliter in men and 12 grams per deciliter in women. Anemia is experienced by patients differently depending on their physical health, their levels of physical activity, and both inner and outer elements such as nutritional state and altitude. Therefore, patients with a very low hemoglobin level may not display too many symptoms while another patient with low-grade anemia has many different alterations and symptoms. Thus, we can’t assume anything with anemia, and we may have it and yet feel nothing at all.
However, there are a series of signs and symptoms commonly experienced in patients with anemia, and they are as follows:
The blood contributes to the colouration of the skin because there are millions of minute blood vessels continuously circulating blood near the surface of the skin. These blood vessels contain red blood cells, which are filled with hemoglobin. Hemoglobin has a bright red colour when it contains oxygen, and gives your skin a reddish appearance that contributes to the normal tone of the skin. Conversely, patients with anemia reduce their circulating levels of hemoglobin and do not give the same reddish tone to the skin. It looks rather pale and whitish, and sometimes might turn a bit yellow and become difficult to differentiate from jaundice.
