Gastroenterology Insights I: Portal Hypertension Explained #gastroenterologyinsights #ascites #meded

There is actually no damage to the kidneys, but kidney perfusion is reduced. The blood flow is reduced. Why would kidney perfusion be reduced? Well, an example is because of insufficient blood supply to the kidneys. To see what happens, we would first try to see why we would have insufficient blood supply to the kidneys. It's actually all portal hypertension's fault or obstruction of blood flow through the liver somewhere. Because remember, we have all this blood flowing from all these organs back to the liver. So, if we have an obstruction of the portal hypertension or portal hypertension, the blood will flow backwards and cause increase in pressure in different tissues around the abdominal region. This can cause a condition known as ascites when we have fluid leaking out of the capillaries due to the buildup of pressure in the portal vein. This will cause blood to flow backwards, causing a buildup of pressure elsewhere, and then fluid will leak out into the abdominal cavity.
