Hi, I understand your concern and I ll try to help you. The generalized edema is called anasarca and is characterized by swelling in the hands, feet, legs, face, periorbital region, ascites, pleural effusion. And anasarca occurs retention or low plasma oncotic pressure on the loss of albumin. There are several causes of anasarca, such as nephrotic syndrome, renal failure, liver failure, cardiac failure and conditions such as rare Menetrier s disease. Nephrotic syndrome is a loss of blood proteins such as albumin in the urine and is related to infectious diseases such as hepatitis B and C, HIV and genetic diseases such as lupus. In renal insufficiency, there is a loss of the ability of the kidneys remove excess water from the body. The problem liver failure is the low production by albumin liver. In heart insuficiuência the problem is the loss of contractile function of the heart, with blood pumping loss and consequent anasarca by fluid retention. The Menetrier disease is a strong possibility for your case. It is a rare disease in which there is loss of plasma proteins such as albumin by some areas of the digestive tract, more frequently the stomach. When it affects the stomach, this organ gets aspect that resembles watermelon on endoscopy. The diagnosis is made by endoscopy, colonoscopy, abdominal CT scans and biopsies of suspected sites. The treatment is carried out with drugs such as albumin and lasix, and in refractory cases, with surgery for resection of the segments of the digestive tract responsible for the loss of proteins. Your doctor is on track of the definitive diagnosis. Hope I have answered your question. If you have any further questions I will be happy to help you. Wish you good health.
