Mom just landed in hospital and found out she has gallstones and inflamed gallbladder- they are calling to remove gallbladder in the next few days. What is your experience?

I’m honestly exhausted as I’m writing this so bear with me if I sound jumbled. My mom had her first experience of gallstones and took her to hospital to find this out- doctor is saying he wants to remove gallbladder tomorrow or next day. My head is in a tailspin because I know nothing about this. I see so many people fighting to keep their gallbladder. Is this a rushed decision? I don’t want to put her in danger or harms way. She is already dealing with so much health wise. Looking for everyone’s opinion
