I've had three inguinal herinas repaired. I don't remember my surgeon telling me not to lift, but I think that anything that would risk strangulating your intestine (when they slip through the hole) isn't worth the risk.
If you've got surgery scheduled to repair it, they'll prolly put in lots of mesh to stitch your abdominal wall back together, and your belly should be tougher than it was before.
You might want to ask your doctor if it's ok for you to lift, and what specific things you should avoid. I remember doing crunches when I was waiting for surgery and wondering if I was doing more damage to the hernia. It seemed to bother me the most just standing (I have jobs where I'm on my feet all day). It might be ok to do upper body lifts (arms/back/shoulders) and cals/hamstring work, but I'm not sure about lower back/quads/abs. I'd really ask the doctor what he thinks.
At any rate, if the surgery goes well, your abdominal wall will be tougher than it is now, and you should be back to lifting in a couple weeks (I think that's how long I took off from lifting.....)
If you have the hernia now, do not lift. The additional pressure will cause it to get worse.
When you lift do you hold your breath and bear down, The valsava maneuver. It is best to exhale as you lift anything as to not create this pressure. Also building ab strength and contracting you abs when you lift anything help prevent against a reccurring injury.
As far as your stomach wall being stronger because they put mesh in the hole is not true. You have had three hernias at a young age. does that tell you anything. Just as anything muscles, tendon ligament in the body once damage has been done and repairs made it will never be full 100% as before the injury.
Once it is repaired you can lift but you have to strengthen your core first and use proper lifting mechanics to reduce the chance of a recurring injury
my bad forgot to add that i know i have a hernia (sister is a MD) but i havent officially went to the doctor and she hasnt had time to properly diagnose how bad.So i am going to a different doctor on wednesday..
People who use E-stats piss me off, because some of us actually work to get where we are.
Yes, you can lift after you had it repaired. I had a hernia due to squats and deadlifts which are usually the cause of hernias. Markus ruhl said deadlifts caused his hernia. I do not deadlift or squat anymore, but still do everything else!
