What organs are affected when you have anemia?

Possible Complications. Severe anemia can cause low oxygen levels in vital organs such as the heart, and can lead to heart failure.

Can anemia affect cognitive function?

Anemia, or a low red blood cell count, is associated with an increased risk of mild cognitive impairment, a form of memory loss that often precedes Alzheimer’s disease.

What do people with anemia have low levels of?

In a routine blood test, anemia is reported as a low hemoglobin or hematocrit. Hemoglobin is the main protein in your red blood cells. It carries oxygen, and delivers it throughout your body. If you have anemia, your hemoglobin level will be low too.

Symptoms such as pallor, fatigue, and shortness of breath are characteristic of anemia but can also occur with a range of different medical problems. Some individuals can exhibit muscle weakness, a decline in motor skills and mental changes such as memory loss.

Can anemia cause lack of oxygen to the brain?

Iron deficiency anemia (IDA) can cause the brain to receive less oxygen than it needs to function optimally, leading to basic headaches. IDA has also been associated with migraine, especially in women who are menstruating.

Complications. The most serious complications of severe anemia arise from tissue hypoxia. Shock, hypotension, or coronary and pulmonary insufficiency can occur. This is more common in older individuals with underlying pulmonary and cardiovascular disease. (See Pathophysiology .)

How does anemia affect the erythrocyte in the Aging Cell?

In addition, the aging cell has a decrease in potassium concentration and an increase in sodium concentration. These factors contribute to the demise of the erythrocyte at the end of its 120-day lifespan. The physiologic response to anemia varies according to acuity and the type of insult.
