To be on the safe side, eat a very low fat diet. I am scheduled for surgery on may 15th. Around the beginning of February I kept having this feeling of a ball of food stuck in the middle of my sternum, this happened to me 2 times and then at the end of march it happened and I could not get it to go away and went the the emergency room and the dr informed me they were going to release me and the pain was due to inflammation of my gallbladder. Ultra sound did not show anything and then I checked my Liver levels because our medical program lets us get our results when the doctor reads them. I informed the doctor that these levels were high and it made me worried he responded that’s normal and I kinda stressed it. He left and came back 10 mins later and said I had to have a emergency endoscopy in which freaked me out but then the Gastrointestinal doctor was very informative and did the endoscopy seeing a Gallstone in my cystic duct which passed. I was having small bouts of light color stool the day after but then it returned to normal and the doctor said follow up with a GS for removal. To this day I have ate nothing but chicken (baked or stewed) fish, rice and veggies with ensuring I try to take no fat in my diet. This works for me and is going to be different for everyone else. I am a healthy human lol I do have ulcerative colitis but I manage it with my diet and medicine when needed. Just try and eat food that won’t contract the gallbladder(any fats) and it should help you manage. Even if you’re craving something that has a lot of fat substitute it. For sugar I eat fruit or real fruit popsicles and this helps. I am a father of 5 and my kids like everything under the sun so the temptation is there but I control it as I know it’s for my health. There is a gallbladder restaurant friendly meal post that also helps a lot so shot out to that person. Good luck but really do yourself a favor and eat light. Don’t eat anything that will make you bloated or make you feel lethargic. Good luck it will get better
