Causes of abdominal effusion in men

I believe everyone must know the importance of the abdominal cavity to us. There are many important organs hidden in our human abdominal cavity. If there is a problem with our abdominal cavity, it will not only easily bring us pain but also bring us a lot of psychological pressure. Therefore, we recommend that you protect your abdominal cavity in daily life. Ascites is a common abdominal symptom. Below we introduce the reasons why ascites occurs in men.

1) Increased portal vein pressure: Normally, the hepatic sinus pressure is very low (0-2mmHg). When the portal vein pressure is high, the hepatic sinus pressure increases (portal pressure of 10mmHg is the basic condition for the formation of peritoneal effusion), and a large amount of fluid flows into the Disse space, causing excessive production of hepatic lymph fluid. The volume of cirrhosis patients is often 20 times that of normal people. When the chest duct cannot drain too much lymph fluid, it leaks directly from the liver capsule into the abdominal cavity to form peritoneal effusion. Increased hepatic sinus pressure can also cause activation of intrahepatic pressure receptors, which reduces the excretion of sodium by the kidney through the hepato-renal reflex, aggravating sodium retention.

2) Dilation of visceral arteries: In the early stages of cirrhosis, visceral blood vessels dilate, and the effective blood volume is maintained within the normal range by increasing cardiac output and heart rate. In the advanced stage of cirrhosis, visceral artery dilation becomes more obvious, resulting in a significant decrease in effective arterial circulating blood volume and arterial pressure, which in turn activates the sympathetic nervous system, the renin-angiotensin-aldosterone system, and increases the release of antidiuretic hormone (ADH) to maintain arterial pressure, causing renal vasoconstriction and sodium retention. Portal hypertension interacts with visceral vasodilation, changing the intestinal capillary pressure and permeability, which is conducive to the accumulation of fluid in the peritoneal cavity.

3) Decreased plasma colloid osmotic pressure: Patients with cirrhosis have reduced intake, decreased liver reserve function, and decreased ability to synthesize albumin, which leads to decreased plasma albumin and, in turn, decreased plasma colloid osmotic pressure. A large amount of fluid enters the tissue space, forming peritoneal effusion.

4) Other factors: Relative deficiency of sodium in the plasma center and decreased sensitivity of the body to it, decreased estrogen inactivation, increased secretion of antidiuretic hormone leading to drainage dysfunction and decreased secretion of prostaglandins, resulting in renal vasoconstriction, decreased renal perfusion, and redistribution of renal blood flow, all of which are related to the formation and persistence of peritoneal effusion.

In the above article, we introduced the importance of the abdominal cavity to us. We recommend that our readers take good care of their abdominal cavity in daily life. Ascites is a symptom that is easy to occur in the abdominal cavity. The above article introduces in detail the reasons why ascites occurs in men.
