I had laproscopic gall bladder removal 10 years ago. My first surgery since tonsils at the age of 3 - a LONG time ago!. I was most nervous about the anesthesia but the surgery went well. Actually when I woke up in the recovery room my first thought was that I had fallen asleep at my desk at work which really shocked me into being fully awake
Once I realized where I was and I made it through surgery ok, I was in a "let's get me out of here" mood because I really just wanted to go home and rest. The anesthesia sometimes makes people feel nauseated after surgery but I must have gotten just the right amount because I was not groggy or feeling nauseated, nor did I have trouble breathing or that chest heaviness.
I was feeling well enough to go home - could have spent the night at the hospital but after a few hours of being awakened constantly GRRRRRR, I begged to go home. Got home around 6:30pm and conked out until the next morning. The pain was minimal, more of a stretch the skin pain, like having a bandaid on too tight and it's pulling the skin. I had prescription pain meds but only took one, didn't like how Vicodin made me feel and was able to get by with just Tylenol. I took 3 days off from work and went on an interview 2 days after surgery - the pantyhose were really uncomfortable! I felt good but surgery is a trauma on the body and you will tire easily. I was back at work on Monday and did well. However, I know others who actually had alot of pain for 3 - 4 weeks after surgery. I think it depends on how much "digging around" they do inside you to get the gall bladder out.
I will say that you do have to adjust your foods post surgery. Getting the gall bladder out is not a cure all and it introduces other issues. It's not like you can go back to previous eating habits. One of the things the gall bladder does is to metabolize fats. Eat a fatty meal and you will either get heartburn, diarehha (sp?) or those awful "verps" - the burp that has that burning awful taste.
For over a year after surgery I had terrible acid reflux after eating tomatoes, pizza, some spagetti sauces, mayonaisse or anything overly fatty. I still have problems but I do try to exercise moderation and have had to experiment with which foods affect me more than others.
My advice - rest after surgery. You might feel good but you've been cut and yanked internally and you need to let your body rest and heal. It takes longer to heal internally than externally. Over do it physically and you'll be in a world of hurt the next day. Everyone is different and while some people are fine in a week, it might take longer for others. Follow your doctor's orders. Take your temperature for a few days after surgery if they say so to monitor for infections. Slowly introduce foods back into your eating plan. If something's going to bother you, you'll know within a few hours. And I don't know of anyone who could totally go back to their pre-gall bladder eating habits. Everyone had to make some adjustments based on how different foods affected them.
Good luck to your husband!
