Anemia or anaemia (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.

Global trade and rules set forth by the World Trade Organization can actually benefit the health of people by making their incomes higher, allowing them to afford better health care, but making many non-communicable diseases more likely as well.

Hemolytic anemia affects nonhuman species as well as humans. It has been found, in a number of animal species, to result from specific triggers. [51] Some notable cases include hemolytic anemia found in black rhinos kept in captivity, with the disease, in one instance, affecting 20% of captive rhinos at a specific facility.
Anemia, especially iron-deficient anemia, is a critical problem for cognitive developments in children, and its presence leads to maternal deaths and poor brain and motor development in children. [2] The development of anemia affects mothers and children more because infants and children have higher iron requirements for growth. [ 118 ]
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Pernicious anemia often presents slowly, and can cause harm insidiously and unnoticeably. Untreated, it can lead to neurological complications, and in serious cases, death. [19] The onset may be vague and slow and the condition can be confused with other conditions, and there may be few to many symptoms without anemia. [20]
Biotechnology can pose a global catastrophic risk in the form of bioengineered organisms (viruses, bacteria, fungi, plants, or animals). In many cases the organism will be a pathogen of humans, livestock, crops, or other organisms we depend upon (e.g. pollinators or gut bacteria).
