hypertension after dialysis

Post-dialysis hypertension is a prevalent complication that typically emerges following dialysis sessions and can negatively impact a patient's health. It may stem from various factors, such as fluid and sodium retention, activation of the renin-angiotensin system, and heightened sympathetic nervous system activity. These factors can contribute to increased cardiac strain and elevate the risk of cardiovascular events.

Primarily, fluid and sodium retention ranks among the most frequent causes of hypertension following dialysis. If the dialysis process fails to adequately remove excess water and sodium from the body, it can result in expanded blood volume and higher blood pressure. Additionally, the activation of the renin-angiotensin system can also trigger an increase in blood pressure. During dialysis, impaired kidney function may lead to increased renin secretion, thereby activating the angiotensin system and causing blood vessels to constrict, which in turn raises blood pressure. Furthermore, factors such as pain and anxiety during dialysis can enhance sympathetic nervous system activity, leading to elevated blood pressure.

Patients experiencing hypertension post-dialysis should have their blood pressure monitored regularly and adjust their antihypertensive medication dosage as directed by their healthcare provider. It is also crucial to manage dietary intake by limiting sodium and maintaining an appropriate level of hydration to alleviate cardiac stress. Maintaining a positive mental attitude and avoiding excessive tension and anxiety can also help reduce the risk of elevated blood pressure. Persistent symptoms of hypertension warrant prompt medical attention for specialized treatment.
