Hello. Thanks for using this forum. As for the incisional hernia, it is advisable that you should start wearing a hernia belt which should have been the first thing you should have done after the c-section operation. Since you mentioned you had fatty abdomen, such body type is at risk of developing hernia due to lack in strength of abdominal muscles. Secondly you are also diabetic which will be a concern if you opt out for hernia surgery, since diabetics are more prone to infection and slow healing. Advise would be to wear hernia belt, follow up closely with the symptoms such as any increase in pain, vomiting episodes which would suggest strangulation and avoid doing any strenuous type of work such as lifting heavy objects. Kindly feel free to ask if you need further clarification. Regards.
