Yes, I assume it has to do with medications, and changing internally. I do not think you wake up one day with Fibro, Lupus or sjogren, but I think it is a gradual take over of your body and there is much change that takes place.

I have alot of sensitivities to food. i also have IBS_C. so my doc gave me a script to handle the nausea. i lay down when it is bad.

I had pneumonia in Jan and have not regained my appetite since then. Frequent nausea and vomiting.

I throw up alot. Stomach never right. I try small snacks cuz a big meal would be bad

yes i have had stomach issues since childhood (trauma). Over the years it has gotten worse. I do not eat in until 11:00 am and then i force myself to eat around 3:30. and then again around 7:00 pm. like @ Dayna-aka-Ayiana i have learned that i cannot tolerate alot of foods. My diet is bland and it is boring. Mind i tell you that i do get naucous after every small meal, even though i have eliminated many foods from my diet. I have been perscribed Zofran which is a anti naucous medicine. The naucous is debilitating and i have to lay down. My pychiatrist tells me my eating is disordered. cause i dont eat 3 meals a day at the same. time. He says it is important for metobolism and IBS-c. Well i told him i am just one big disordered person, LOL!!! hope this helped! hugs
