i have abdominal pain occasionally and once, when i didn't have time to eat for a few hours, i start to have an extremely painful feeling in my abdomen. So my mom suggested me to eat and even though i'm nt hungry, i forced myself to eat and i felt a lot better. But i still have abdominal pain and sometimes i will feel pain after urine but my urine is colourless and doesnt have any smell. I will feel hungry very fast, like 1-2 hours after meals even though i eat a lot during meals. I'm wondering is my lack of sleep making me feel hungry easily and i get tired easily. Are all these symptoms just because of lack of sleep?
