Sir/Madam, I study in Class XII and am preparing for NEET and therefore I usually study till 1 o clock and get up at 7. I cant eat anything at all. Whenever I try to eat, even looking or thinking of the food brings nausea to me and I might vomit while eating. I cannot eat much at all. I have an irritable temper. Most of all,if the food is not tasty, I cannot eat at all. Sometimes, my leg pains due to gas formation. Eating nothing for 5 6 hrs causes acid. I am fed up with my life. Kindly advise what disease I am afflicted with. Previously one doctor gave me Nexpro L which worked well for a few days. I have irregular bowel movement.
