Acute Nephritis And Hypertension: Understanding The Connection And Treatment Options

One of the primary causes of hypertension in patients with acute nephritis is a significant decrease in the glomerular filtration rate. This reduction leads to a lower production of primary urine. However, the renal tubules continue to function normally in reabsorbing water from this urine, which results in an increased blood volume. The excess fluid in the bloodstream can then cause a noticeable rise in blood pressure.

How Acute Nephritis Affects Blood Pressure

When the kidneys are affected by acute inflammation, their ability to regulate fluid balance is disrupted. As the glomeruli become damaged, the filtration process is impaired, but the tubules remain efficient at reabsorbing water and electrolytes. This imbalance leads to fluid retention in the vascular system, which directly contributes to elevated blood pressure levels.

Treatment Approaches For Hypertension In Acute Nephritis

The primary treatment for hypertension caused by acute nephritis is diuresis. By using diuretic medications, excess fluid can be removed from the bloodstream through increased urine output. This helps reduce blood volume and, in turn, lowers blood pressure. However, in some cases, patients may not respond adequately to diuretics and may continue to experience oliguria (reduced urine output).

Advanced Intervention For Fluid Retention

When diuretic therapy fails to improve urine production and fluid buildup persists, dialysis may be necessary. Dialysis serves as an effective method for removing excess fluid and waste products from the blood, which can significantly improve blood pressure control. It is often considered a critical intervention in cases where acute kidney failure develops as a complication of severe fluid retention.

Comprehensive Management Of Acute Nephritis-Induced Hypertension

Managing hypertension in acute nephritis involves a multi-step approach. Initially, diuretic therapy is initiated to promote fluid excretion. Alongside this, it's essential to restrict dietary sodium and fluid intake to prevent further fluid accumulation. Antihypertensive medications may also be prescribed to maintain safe blood pressure levels. In more severe cases where kidney function deteriorates rapidly, dialysis becomes a life-saving treatment option to manage both hypertension and acute kidney injury.
