I have got level 2 ultrasound done for my wife, she is having baby of 4.5 months, in the report everything was normal except the kidney of fetus. It is having variations in size it reads as 1.2 mm for one and 3.9 mm for another one. Is it problem what shall we do to make equal in size any diet plans to reverse it? Doctors advised that it is because of excess potassium, she was having 2/3pcs bananas daily, now she has stopped eating it due to this. Kindly help.
