Is the patient looking pale and exhausted? If you answered yes, you should be concerned about anaemia symptoms. Adults experience anaemia in a variety of ways. A lack of haemoglobin has a wide-ranging impact on the organ systems of the body. We'll look at anaemia symptoms in relation to the organ in question. Come find out the essential about low iron levels and Anaemia "Anaemia is a condition in which the number of red blood cells or the haemoglobin concentration within them is lower than normal. Haemoglobin is needed to carry oxygen and if you have too few or abnormal red blood cells, or not enough haemoglobin, there will be a decreased capacity of the blood to carry oxygen to the body's tissues. This results in symptoms such as fatigue, weakness, dizziness and shortness of breath, among others. The optimal haemoglobin concentration needed to meet physiologic needs varies by age, sex, elevation of residence, smoking habits and pregnancy status. The most common causes of anaemia include nutritional deficiencies, particularly iron deficiency, though deficiencies in folate, vitamins B12 and A are also important causes; haemoglobinopathies; and infectious diseases, such as malaria, tuberculosis, HIV and parasitic infections."WHO
