Doctors only please help?

So I'm a 15 year old girl and I haven't been feeling bad, just weird. It started on Monday.

this are my symptoms:

1. Total loss of appetite (I mean my stomach hurts from the hunger but I have to force myself to eat)

2. Extreme thirst!

3. No poop

4. little pee (comparing how much water I've been drinking)

5. a lot of gases

6. Sometimes I have a weird taste in my mouth

7. My belly seems to be getting bigger

8. NOTHING hurts



I started keeping track of what I've eat and well defecated LOL

this is so far:

yesterday:

1st pee: around 8PM.: yellow

2nd pee: around 10 PM: really light yellow

NO poop

I ate:

1 cup of milk (200 ml)

1 1/2 hot cakes

1 hamburger (with only 1 meat)

2 pieces of pizza

My mom made me eat



Today so far:

1 pee: yellow : approx 12 PM

I ate:

half a cup of milk with sugar



*the food I've eaten is really few comparing to what I normally eat

It's weird

help?? what should I do, I already told my mom, but shall I worry?Doctors only please help?
okay so, your pee getting a lighter color is because of your water intake. the more water you drink the lighter color your pee is(this is a good thing). does you mother notice the change with your stomach size. if she does i would say it might be bloating caused by the water. start eating some veggies and fruits(this will clean out your system, and you have to give it at least a month) and if the problem still expires then i would suggest going to a G.I. system doctor and have them analyze your waste. it might be something in your system. don't worry unless your weight drops dramatically, and then you really need to get it checked out. keep a food diary, just in case you have to go to the doctor. the food diary might help them figure it out sooner.
