A Kidney Problem Causing High Blood Pressure

A kidney problem can cause high blood pressure in certain people. Our blood pressure is largely determined by our kidneys. There are many hormones in the kidneys that can affect blood pressure depending on certain circumstances.

High blood pressure can be caused by a blocked blood supply to the kidneys. Angiotensin is released by the kidneys when there is not enough blood flow. This causes blood vessels to constrict and increase blood pressure. When angiotensin has been released, the adrenal cortex releases aldosterone.

Understanding how angiotensin works are key to understanding the kidney problem. Angiotensinogen is the precursor that makes it. This alpha-2-globulin is released from the liver. It is made up of 453 amino acids. Angiotensin I is formed by the action of renal renin on the angiotensinogen protein. Angiotensin 1 is a precursor of angiotensin 2.

The kidney problem in high blood pressure gets worse when an enzyme called ACE (angiotensin-converting enzyme) transforms angiotensin I to angiotensin II. Blood pressure rises because of angiotensin II. Angiotensin II does not degrade and is replaced by angiotensin III or angiotensin 4. These have a lower effect on blood pressure.

High blood pressure is caused by constriction in the veins and arteries by angiotensin 2. It promotes blood clots by promoting adhesion and the accumulation of platelets. It may also play a role in thickening and expanding the heart.
