Sudden weight gain but low appetite??

[tatwo]

I am a 29 year old female and within the past couple of weeks, I've noticed I've gained about 10lbs. No, I am not pregnant. This doesn't seem like a lot of weight, but being that I've been a solid 110lbs(or was) for the past 2 years, it's a big deal to me.
On top of that, I just don't have an appetite and when I do eat, my stomach gets all "gurgly" and gassy. I have constant stomach aches, especially in the morning. I do not eat any dairy products or breads because I have a food intolerance to the milk protein casein, however, it seems like everything is bothering my stomach.
on a typical day I have a bowl of my organic homemade cereal with soy milk, an apple for lunch, water throughout the day and a healthy dinner. I do not eat junk food either and if I do, it's just plain popcorn.
Any thoughts??
I'll be making an appointment with my naturalistic doctor soon.

Thank you for your reply, That was helpful. I have a doctors appointment Feb.22nd I think it is...the soy allergy could possibly be the culprit too. I drink it every day/morning and have it with my homemade cereal...I'm gonna try cutting it out and see if that helps!

I would definitely see a doctor, though for this, I would see a regular medical doctor or a gastroenterologist. It could be something with your digestive system (soy intolerance, irritable bowel, possibly even a problem like gastritis, colitis or diverticulitis since the popcorn may be bothering you; maybe even gallbladder problems because foods like raw apples, onions, broccoli, cabbage, etc. can aggravate that.) My sister was ending a fair amount of soy while going through perimenopause, had severe gas and bloating; ended up she has a soy allergy.

Please keep us posted.
