My mother who is 52 years old is suffering from gallstone. In June we got to know that she is having 9.5mm stone in her gallbladder. But the problem is she is a patient of Parkinson's s and also she is loosing weight rapidly. Now she is oonly 35kg. I want to know that how can i make her gain weight??so that docs can perform the laproscopic surgery. All suggestions are welcome..
