Weight gain from SIBO?

I was officially diagnosed with SIBO 2 years ago, and have had it since about 2020. Since then, I’ve taken antibiotics at least 3 times, three rounds each time.

First time, I finally felt so free and normal! Then 6 months later it cames back with a vengeance, this time excessive super eggy farting ALLLL the time. Stopped immediately after getting back on antibiotics.

Then, recently this past July I noticed I was bloated all the time - and whatever bloat or weight gain I got during peek period time never went away. It only did when I took a laxative in conjunction with Linzess I was already one. I’m talking like normal weight range for over a year being 141-143 then suddenly spiked to close to 147 and now no matter what I do will not budge.

My eating habits have not changed in that timeframe, I eat most clean foods. I’m talking black coffee for breakfast (not hungry in the am), salad with chicken, peppers, cucumbers, and mushrooms with no dressing for lunch OR a protein shake. Dinner is usually a protein (chicken or steak) with a side of spinach or veggie like brusselsprouts. Occasionally get takeout, but generally keep it on the healthier side. Like Egg Fo Yung etc..

I’ve gone low FODMAP, and moved more to Keto/Carnivore and I workout 4-7 days a week, either by walking + cardio/strength or an extended walk/run depending on the day and energy…

I figured might be a SIBO flare, but after this recent round of antibiotics I’ve seen no change. Occasionally my weight will suddenly drop to 144-145 and I start to feel normal, but then like 2 days later it’s up to almost 150 with me still majnothe above.

I’m about to contact to my GI for another breath test, but has anyone else had this experience before? I feel like I’m running myself ragged trying to feel better and just nothing is working.

Not to mention, the inconsistency of bowel movements. There’s times where it will be several days with nothing other times refusal everyday for a week. Normal size stool one day and thin pencil ribbons the next..

Guys, I just wanna be normal again 😭😭😭
