Hello doctor, My grandfather was diagnosed with jaundice a month ago. We got to know that he has obstructive jaundice due to gallbladder stones. He has undergone ERCP. There is improvement in Jaundice but the haemoglobin has decreased to 5.7 and so, he is really weak. The doctor  has suggested further tests for a knot found in his bile duct. If there's  nothing to worry about (less chances of something serious), his knot will be removed. My main query is about the very low haemoglobin and his weakness. He is even unable to sit properly. Although, he is talking and having a liquid diet. He is diabetic too.
