ascites is one of the late features of
Ascites In the developed world, the most common cause is liver cirrhosis.[3] Other causes include cancer, heart failure, tuberculosis, pancreatitis, and blockage of the hepatic vein.[3] In cirrhosis, the underlying mechanism involves high blood pressure in the portal system and dysfunction of blood vessels.[3] Diagnosis is typically based on a examination together with ultrasound or a CT scan.[2] Testing the fluid can help in determining the underlying cause.[2]
Isostasy When large amounts of sediment are deposited on a particular region, the immense weight of the new sediment may cause the crust below to sink. Similarly, when large amounts of material are eroded away from a region, the land may rise to compensate. Therefore, as a mountain range is eroded, the (reduced) range rebounds upwards (to a certain extent) to be eroded further. Some of the rock strata now visible at the ground surface may have spent much of their history at great depths below the surface buried under other strata, to be eventually exposed as those other strata eroded away and the lower layers rebounded upwards.
