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]
If left untreated, acute iron poisoning can lead to multi-organ failure resulting in permanent organ damage or death. [ 1 ] Iron is available over the counter as a single entity supplement in an iron salt form or in combination with vitamin supplements and is commonly used in the treatment of anemias .
Lead exposure can occur from contact with lead in air, household dust, soil, water, and commercial products. [25] Leaded gasoline has also been linked to increases in lead pollution. [99] [100] Some research has suggested a link between leaded gasoline and crime rates. [101] [102] Man-made lead pollution has been elevated in the air for the ...
Red blood cells normally survive an average of about 120 days, becoming damaged (their oxygen-carrying capacity becomes compromised) as they age.
Anemia (also spelled 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.
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]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Lead poisoning or poisoning by arsine or stibine causes non-immune hemolytic anemia. [6] Runners can develop hemolytic anemia due to "footstrike hemolysis", the destruction of red blood cells in feet at foot impact. [13] [14] Low-grade hemolytic anemia occurs in 70% of prosthetic heart valve recipients, and severe hemolytic anemia occurs in 3% ...
