anemia
Sign in to saveAnemia (also spelt anaemia in British English) is a blood disorder in which the blood has a reduced ability to carry oxygen. This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function. The name is derived .
AI overview
Anemia is a blood disorder where the blood cannot carry oxygen as effectively as it should, either because there are fewer red blood cells than normal, there isn't enough hemoglobin to transport oxygen, or the hemoglobin isn't working properly. This matters because your body's tissues need oxygen to function, so anemia can lead to fatigue and other health problems if left untreated.

When anemia comes on slowly, the symptoms are often vague, such as tiredness, weakness, shortness of breath, headaches, and a reduced ability to exercise. When anemia is acute, symptoms may include confusion, feeling like one is going to pass out, loss of consciousness, and increased thirst. Anemia must be significant before a person becomes noticeably pale. Additional symptoms may occur depending on the underlying cause. Anemia can be temporary or long-term and can range from mild to severe.
