Another problem caused by high pressure in the veins of the liver is ascites. Fluid leaks out into the belly and it begins to fill it up. This can make the abdomen enlarge like a balloon filled with water. The legs can get swollen too. This can be very uncomfortable. Eating can be a problem because there is less room for food. Even breathing can be a problem, especially when you are lying down. But the most dangerous problem with ascites is infection, which can be life-threatening.
