anemia cause hypertension

Anemia can result in hypertension. Anemia is characterized by a reduction in the number of red blood cells or hemoglobin levels in the blood below the normal range, which may lead to an increased workload for the heart to compensate for the decreased oxygen delivery, potentially leading to elevated blood pressure.

To be more specific, when the body experiences hypoxia, the kidneys release erythropoietin, a hormone that stimulates the bone marrow to produce additional red blood cells. Concurrently, the kidneys secrete renin, which activates the renin-angiotensin system, causing blood vessels to constrict and blood pressure to rise. Moreover, anemia may cause the heart to enlarge, further aggravating the cardiac workload and increasing the risk of hypertension.

Consequently, it is essential for individuals with anemia to have their blood pressure monitored regularly and to receive treatment under a physician's supervision. Additionally, enhancing dietary intake of iron and vitamin B12 can help alleviate anemia symptoms and mitigate the risk of hypertension.
