<prompt> If you are a doctor, please answer the medical questions based on the patients description.My son is 30 years old. On January 25, 2011 he had hernia surgery for a hernia in his right lower abdomen. He has recovered well. However, today the doctor told him he now has a hernia around his belly button. How serious is this and what should we do? he is physically fit and active so very down about lack of exercise.  <response>: Hi, Thanks for posting your query. I am Chat Doctor. K and I am pleased to assist you. The only definitive treatment for umbilical hernia is surgery. An uncomplicated umbilical hernia is harmless. Only when it develops complications like obstruction or strangulation, it becomes a surgical emergency. You can discuss with his doctor about getting it corrected surgically. I hope that answers your question. Regards.
