How do you control uncontrollable Burping and Belching?

My research indicates that there are two types of gastroparesis; diabetic and idiopathic. My sister has gastroparesis and has had IDDM for 55 years. I have Parkinson's Disease x 9 years and believe I may have idiopathic (no known cause) gastroparesis. I suffer from bloating and pain after small amounts of food and water. I wonder if this could be a non-motor symptom of PD? Even small amounts of water make me very uncomfortable and difficult to belch. However, I do not get nauseous or vomit. Any suggestions?

No I tried gummies a couple yrs ago w/ THC in them . Hated it , they were too strong .
I do take a sleep gummy w/ 1 mg THC / CBD / Lavender/ chamomile/ valtarian int sometimes .
It happens if I’m outside house 🏡 too . I don’t go too many places though anymore.
It’s worse laying down but I’m so fatigued so much from not eating much .
We are on 2 hr car ride home from daughters & family and I’ve deep wet belched over 300 x in car .
I’m very exhausted and hungry but nausea is bad .

It may be SIBO which many doctors don't have the knowledge or experience in diagnosing or treating- have You tried all liquid diet to help eliminate bad bacteria if present? They feed off carbs and sugar. Elemental diet could be worth a shot, its fairly expensive and it can take 3-4 weeks of starving those bugs to get a bit of relief. Also could be fungal- candida?

I asked GI Dr. to order the bloodwork for Candida , even gave her the codes for each test . She doesn’t do that and even if she did she said she would not know what to do w/ results because most Yeast ( Candida ) infections are in woman’s Vag or Thrush in mouth ( I don’t have either symptoms of those ). I def think it could be in gut though !

I’ve been tests many times for SIBO through the years. Also Long H Pylori Breath test .
All were negative as was 5 hr gastric emptying study years ago .
I’ve had 3-4 Endoscopy & colonoscopy’s last 11 yrs . Last one was a year ago w/ biopsies.
Upper GI series , Cscans w/ contrast , Endo flip , MRI .
Saw FM Dr. Did elimination diets . Did food allergy testing .
I did have inflammation which was found after 12 viles of extensive blood test from FM Dr.
Tried Keto , & diff supplements again .

So we know what I have , but no RX or supplements have helped or pre - pro biotics and digestive enzymes. Only did liquid diet when doing colonoscopy preps .
I eat small , & hate eating period .
The GERD , Gastritis, Small hiatal hernia, diverticulosis all over colon , 700 plus deep wet belching , IBS-M , Esophagitis, non stop churning gut , fatigue, nausea is all just ruining my life . I can’t function like a normal person and do much outside the home or yard.
I even tried hypno therapy 3 x . It didn’t work !! I can’t be hypnotized 😵‍💫!
I talk my NP physc & have rx for anxiety med ( lowest dose , & lowest dose anti depressant ( last 7 months ).
I just cannot get 1 day off of symptoms.
We don’t eat out , or take in only healthy dinner at home 5:30 pm .
My main meal.
It’s so overwhelming & depressing . I try but it’s honestly killing me slowly .
