I dont know if i am the only one but oh well

I have not been told anything like this before. I know that I need to lose some weight though. I hope everything turns out okay for you.

I think your doctor wanted you to lose weight because prior to operation doctors usually order a cardio-pulmonary clearance, depending on your age, meaning a routine check if your heart and lungs are healthy and will be able to maintain vital functions during an operation. Thus is you are overweight/obese for that matter you are in a "medium" risk in a cardiac-pulmonary clearance meaning there is a medium probability that complications may arise from surgery or anesthesia. Another reason is that since (I assume, apologies if otherwise) you are overweight/obese, there is an increase in intraabdominal pressure and weakening of the abdominal muscles pushing your inner organs down hence the hernia. Thus even if surgery is done there might be a risk of re-herniation.
