Inguinal hernia

Hi,
I've been diagnosed with a direct inguinal hernia on the right side of my groin and a smaller one on the left side. I just had a baby 8 months ago and the doctor said that the pregnancy could have made the hernia worse. My question was that I've noticed that I'm losing weight rapidly for no reason whatsoever. I've been eating regularly and there's been no change in my appetite. I've lost 5 kgs in the last 2 weeks, but don't feel faint or sick except for the hernia pain. Has this got anything to do with the hernia or is it something else?
