the thought and smell of food makes me want to vomit

I'm am going through the same exact thing! I'm also 25 and 5'3 ...134lbs. and I f'king LOVE food. but I just got back from a month-long trip to Thailand and ever since I've been back in the states I've been sick. My skin is freaking out and the mere thought of food makes me want to throw up, I try to keep some things down at least like a bit of egg or cucumber with oregano...I don't know what to do.

Me to! I'm 19, and I only weigh 97lbs and I'm 5'4! I dont understand why but even just the smell of butter in a pan (which I used to LOOOVE) makes me want to puke. I've always been pretty thin and have never weighed more than 140lbs but this is crazy! I love food, I love steaks bloody and tender and tonight I nearly gagged trying to force it down my throat after a few bites. Things like tuna, salads, plain white rice, plain spaghetti is okay, but red meats, potatoes, riceroni, chili, ect ect ect is making me sick. Ive lost over 15lbs in the last month alone, lost my period, and its been over 85 degrees everyday these last 2 weeks so coupled with fatigue from not eating properly the heat makes me dizzy and sicker! Im freaking my fiance the heck out though, hes really worried and kinda pissed because even though Im really trying to eat I've still lost so much weight!
Im so sorry I dont have the answer to your questions ): I wish I did!

As for you Jen I think you are having kind of like a food culture shock, in different countries the food is crazily different than in places like America, I went to Honduras on a mission trip for 9 days, I was vomiting the food nearly everyday untill they just started giving me oatmeal or toast for breakfast and plain simple meals all the other times. I think the longer you live in a country with different food styles you become accustomed to it and when going home you have to re-introduce those heavy starchy terrible for you foods to your tummy that America is known for Just give it some time, but hey, not being able to eat fatty foods or just "regular" foods from america probably isnt a bad thing *glaces at her plate* Yea maybe I should cut back on the greasy fatty foods too..

I am 40 and having this same problem I am not thin like others but I have had this problem recently. Every time I want to eat I want to throw up the smell, taste of food makes me sick. Only certain foods I can stomach. Sugar seems to be ok and help actually.
