[|Human|] I am just trying to learn more about pitted edema. My brother has stage 4 brain cancer and is not going to make it long. He is also a diabetic and struggles with his bp. His pitted edema is so bad that he is currently  in a wheelchair and they are bringing in a hospital bed in 2 days, does this mean that his liver and kidneys are going as well?
[|AI|]  Hi, Thanks for writing in. I am sorry to hear about your brother. Diabetes is known to affect the kidneys, eyes and nerves in most diabetics as a chronic complication. The kidneys can also be affected by Chat Doctor.  The same holds good for the liver too. Pitting edema is caused by fluid retention due to heart or kidney disease. Please have a discussion with the treating doctor on the kidney and liver function tests. Check his urine output regularly. Liver disease is suspected if he has jaundice. Kidney function tests are:Serum creatineBlood realizer function tests are:ASTALTAlkaline phosphataseBilirubin (total, direct and indirect)Hope this helps
