Hi there!
Well, without knowing the relevant clinical details or a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include dietary causes, GI motility issues, neuro-muscular causes, connective tissue disorders such as scleroderma, GI infection/ inflammation, micronutrient deficiencies, non non-GI causes such as stress/ anxiety, hormonal/ endocrine imbalances, metabolic issues, micronutrient deficiencies, medication side effect etc. It would be best to discuss the situation and the suggested management plan in detail with your treating doctor.
Hope this is helpful.
Take care!
I am going to try and repost this so maybe someone might have some ideas?
