Two months ago I felt weak after I got out of a shower and fainted. Three weeks ago I fainted again. I went to the ER where they performed numerous tests (just not a CAT scan or MRI) to find that I just fainted due to being in the same position for an extended period of time which I'm not sure I believe. Around the same time my stomach began to feel bloated even though it did not grow, and felt sensitive to the touch. Also my normally healthy appetite has been lost, and the thought of foods that I normally LOVE make me nauseated. I didn't mention it at the ER because the symptoms were new and I thought it was a strange stomach ache from nervousness so I didn't mention it. It's been almost a month and I just had my menstrual cycle, so I thought it could have been PMS, however I just finished it and feel all the same symptoms I had before. My stomach has been constantly growling even after I have eaten, and I have been passing gas, which helps my stomach feel a little better, but not completely and I have not been constipated. I'm 22 years old 5'4" and usually weigh 125, however it's gone down to 115 without exercise. My sensitive stomach and appetite loss make me nervous. Do you recognize any of these symptoms? What could it be?
