sudden weight loss and weight gain

i am 22 yr old female. My body has always fluctuated, but the past 2 years have been really strange. about a year ago, just randomly out of the blue i lost about 25 poinds in a month, my diet hadn't changed, and i wasn't trying to lose weight. my doctor had no idea what was wrong. i didn't really have a problem with it but i knew it didn't seem right. she tested my thyroid and everything seems to be fine, and tested me for diabetes and nothing was wrong. and then my weight just went back to normal. well within about 4 months my weight has jumped pretty significantly. i went from 120 lbs and now weigh 155. nothing in my life/diet/routine has changed so i dont know what could cause this. I dont know if this has anything to do with it but ever since i can remember, i've always had constant nausea and dizzyness usually in the morning or at night. i dont actually throw up it just feels like i'm going to throw up all the time. My doctor has also told me i have endometriosis, but i dont know if those things have anything to do with it.[/i]

This may seem a bit odd, but you might try avoiding nightshade foods: potato, tomato, all peppers other than black pepper, eggplant, paprika, tomatillo, huckleberries, and goji berries. Potato, tomato, peppers, and paprika get hidden in many processed foods, and may be labeled as "food starch" (potato starch) or "spices" (often includes peppers or paprika).

I experienced similar problems, including the nauseous feeling you describe, particularly in the mornings, weight changes, and other digestive and muscle problems. These would mysteriously come and go, get better and worse, and the doctors never figured it out. I finally tracked it down as being a problem dealing with the toxins in nightshade foods.

It turns out that there are naturally occurring pesticides in these plants that inhibit an enzyme called cholinesterase. Most people seem to be able to detoxify these compounds well enough that they don't have problems, but some people can't. If you can't, it can build up in your tissues and cause various problems, including ones such as you describe.

It may take a few weeks of carefully avoiding nightshade foods to tell whether or not it helps, since the toxin level falls slowly. However, it's worth the effort to figure out if this is the problem.
