I had laproscopic surgery done in the month of feb this year of inguinal hernia.there was continous weight gain even after so much of food control and my lower abdomen is swelled or there is much weight gain in my lower abdomen part after the surgery. What is the possible reason of this? I get pain sometimes where inguinal hernia was.I had thrice eaten contraceptives also.though it was not needed but for surity purpose.
