Dor de cabeça e falta de ar com todos os suplementos e a maioria dos alimentos. Alguma ideia?

Hi. I went to see a gastro and did upper endoscopy and i was diagnosed with gastrisis and GERD. I dont have any pain but i do have a sensation of shortness of breath after eating. I can feel like it goes right up to my throat. I did the low stomach acid test with baking soda test and no burp at all after 5min. Tried natural remedy such as acv, lemon water, celery juice and ginger. All of this gave me massive headache and runny nose. I suspected this is due to my gastrisis? The most i can tolerate is acv. Thing is, i noticed slight energy increase when i take acv but the side effects headache will come. If i dont take any acv or acidic stuff etc i feel so weak! I feel like sleeping most of the time. Also i noticed when i drink acv, lemon, celery i have more shortness of breath and sensation of fullness even with small meals. But without any acidic drinks i get hungry easier and the shortness of breath is not that bad. I have made an experiment with foods too. I can say the only thing i can tolerate without getting any headache will be rice and bland chicken. I have effects with salt and all fatty foods (all oil, nuts, eggs, avacados). Did ultrasound for gallblader, pancreas, liver all fine. Went for functional medicine and did stool test. Shows i have level 1 candida dubliniensis. Up to level 5. Result also shows i have lack in probiotics (1+ bifidobacterium, 1+ lactobacillus, 2+ Enterococcus, 3+ Esherichia coli, 4+ Bacteroides) The number shows the level. 1 is low. Secretory IGA is high. 350 (51-204 mg/dl). I dont get stool everyday. Vitamin B, neurotransmitter is low. Huge challenge is i cant even take any supplements. Even a simple b complex, multi, vitamin c non acidic form, probiotic powdered form. Even up to nasal spray for my sinus! used to take the nasal spray with no problems. Could this be because of gastrisis that i cant tolerate supplements? Also noticed when i take 1tbsp honey in warm water my body and face feels shrink and i look more pale? gastro gave PPI before this but took it for 3 days only. Got headache like any other supplements and medication as well. Slipperry elm, dgl tried, headache as well. I did try and do smaller meal but more frequent. Only lasted a week. What hard is even 1 tsp of avacados oil gave me headache. is it safe to no fat diet? because i tried lower my fat intake up to 10g a day and i feel horrible in term of energy and also mood. More anxiety. Havent tried bone broth and also cabbage juice. IGG test shows cant take milk, coconut, peas. Even doctors have a hard time how to deal with my situation. And if i were to check for h pylori again should i stay away from honey, green tea or anti h pylori property few weeks before checking? When i did upper endoscope i was taking honey every morning and night. Any sort of input would be really appreciated!

Fat is needed in the diet. Neurological specialist will tell you. Responses are carried by a nodule which has fat surrounding it. If this is depleted then communication can become no longer smooth in its delivery.
Fat is an essential nutrient. Sugar isn’t but refined sugar definately isnt.

You have done all the tests which have pinpointed your intolerances and you already have a diagnosis of gastritis and GERD. Your best bet is to see a dietician to work out a diet plan for you.
