I had mine taken out as an emergency procedure about a year and a half ago. My story is similar to others....I was feeling fine late at night but within an hour and a half I went from thinking I had food poisoning to being on the floor in pain. By the time I reached the hospital I thought I was dying.
Long story short, mine was about to rupture. When they removed it they discovered a gang-green infection in the gall bladder that had spread to my stomach and lungs. Therefore, my recovery also involved ridding my body of any remnants of the infection. It took many months to recover and I was back in the hospital for additional tests that revealed ulcers in my stomach as well. Idk if the infection contributed to that condition or not.
The biggest change is what others have mentioned. Greasy foods can cause serious problems. Also, for me GARLIC is like the kiss of shit death. I coined the term "emergency" to refer to having to go to the bathroom to my daughter so she understands when I am having problems and need to find a restroom immediately.
Make no mistake about it, when you eat the wrong food you will have to go to the bathroom "right then!" Not in 10 min, you won't be able to hold it for 5 min, you have to go RIGHT NOW!
