Hi thanks for asking question. If you have chronic or very severe liver disease then liver is affected and it is unable to function properly. Liver cannot produce albumin which is necessary to maintain oncotic pressure in blood.So defective albumin production lead to decreased oncotic pressure and patient suffer edema. The effective blood volume decreased in cirrhosis , so compensatory increased ADH also lead to sodium and water retention to produce edema. In systemic vein pressure also increased. If edema increasing with ascites diuretic can be given. For pancreatitis symptomatic management done.Rest your Gastrointestinal tract with not taking solid food for few days. So yes this swelling can be because of liver problem. I hope i have solve your query.
