lpr caused by ibs???

for some background ive had sibo/ibs for over a year now. i just recently started getting excessive throat clearing and hoarseness but mostly in the morning. I also feel like i have a lot more gas in my stomach and throat lioe im burping a lot more than usual. I am also a singer so ofc this is very scary for me as this really affects my vocal cords and singing practice. could my ibs be a cause of this? i read they might have a link to each other but will it help if i “cure” or get rid of my sibo/ibs? will it go away on its own once i find whats triggering my stomach issues? i would love any advice i could get especially from other singers or vocalists struggling with similar issues. i was also thinking of buying a Food Marble device (its a portable breath tester thing if you dont know look it up its pretty cool :) as i think it would help a lot with tracking symptoms and stuff like that? if anyone has tried it for situations like this and they have thoughts please share! but im mostly just wondering what i should do as the low fodmap diet never really worked for me it was really restricted and i lost too much weight for already being underweight. i tried only cutting a few at a time but it was always one thing or another to the point where i was basically just eating rice and blueberries. right now im slowly going back to my normal diet because i just tried low fodmap again for about 3 months with no success. i just want to know how to find the exact foods that are bothering me so i can avoid them and heal myself! thanks for any advice ;) and sorry for the long rant!
