Theory about medication

I am aware that autistic people have different tummies. Potentially different tummy acid too. Stomach acid affects absorption of food and medication pills. So could it be that my antidepressants don't work because my tummy isn't absorbing them properly. Just an idea?! I also know that many autistic people on here claim that these SSRI drugs don't do anything for them. Could this reason that I have outlined be the cause? In my case I don't think my tummy absorbs things too well to be honest. Hence why I can take many different pills and have no effects. What do you all think about this?
