I am very worried about my best friend. For months now, she has been having stomach issues. When its not shooting pains iin her abdomen, shes throwing up white liquid. She is rarely able to eat because her food (and even water) just comes right back up. Her symptoms are mostly in the morning. She has gone to a doctor and they put her on anti-acid medication and said her symptoms were because of stress. At the time, her stress was because of a class she was taking. She dropped the class and her stress level has lowered a lot, and still no change. Because she is unable to eat a lot, she sometimes passes out. I am very worried. help? She is 16.
