Why ascites

summary

Every kind of disease appears for a reason. It can't appear without any reason. Ascites is a very common disease in life. It can be caused by a variety of diseases. When this happens, the body will have a lot of symptoms. Now let's talk about why ascites.

Why ascites

First, ascites caused by different diseases often show different accompanying symptoms, such as fever, jaundice, anemia, hepatosplenomegaly, heart failure and other symptoms and signs. As a result of systemic or local factors, resulting in fluid from blood vessels and lymphatic vessels into the abdominal cavity or leakage and ascites. Hypoproteinemia, sodium and water retention, antidiuretic hormone and aldosterone * inactivation function, portal hypertension, hepatic vein obstruction, peritonitis and malignant tumors all contribute to ascites.

Second: the decrease of plasma colloidal osmolality: plasma colloidal osmolality mainly depends on albumin to maintain plasma albumin below 25g / L or accompanied by portal hypertension. Liquid is easy to leak into tissue space and abdominal cavity from capillaries. If water leaks into abdominal cavity, ascites will be formed. This condition can be seen in severe liver insufficiency, middle and late cirrhosis (decreased protein synthesis), nutritional deficiency (insufficient protein intake) nephrotic syndrome and protein loss gastrointestinal disease.

* third: sodium retention: common in heart and kidney insufficiency and secondary cirrhosis with secondary aldosteronism. In cirrhosis and right heart failure, the decrease of natriuretic factor activity increases the sodium reabsorption of renal proximal convoluted tubules. In recent years, it is considered that the mechanism of sodium reabsorption in proximal convoluted tubules is more important than that of aldosterone in distal convoluted tubules; cardiac insufficiency and advanced liver cirrhosis cause a large amount of ascites, which can reduce effective blood volume and stimulate volume receptors and glomeruli.

matters needing attention

It can be seen that the main reason for ascites is the absorption of some tissue fluids by human tissue cells. Sometimes people with fever or a decrease in plasma osmotic pressure can cause fluid to seep into the abdominal cavity from capillaries, leading to ascites.
