I'm really sick - change in diet to blame? :(

It could just be a bug you caught
or
It could be from your diet. Maybe just your bodys way of cleansing out the old while you bring in the healthier new?

However from the type of symptoms, I would say it is more likely a bug you caught.

I do know that headaches do tend to come with diet change. Not sure about the rest though.

I do think you are headed in the right path. A healthier lifestyle can't be a bad thing. I say keep up the fruits and veggies and if symptoms don't improve soon then go to your doctor.

Drink lots of water! and get well soon!

It's possible you caught a bug, especially at this time of the year, but it's equally likely that your diet has done this to you.

There are a lot of "diets" that will cleanse you in that way you speak of, but those diets also are almost completely liquid based (IE The Master Cleanse. Never do the master cleanse). The fact that almost everything you're eating is coming back out again is not good.

I didnt really pay attention all that much to what you'd been eating as far as necessities are concerned, but it's possible you could be limiting your vitamins, minerals, or even basic carbs from yourself in such a way that your body is throwing a temper tantrum.

Actually, now that I think about it, lack of carbohydrates can lead to:
Dehydration
Constipation
Feelings of headache
Fatigue
Aching muscles.

Then again, I'm not a nutritionist or doctor, so maybe you should see the campus clinic? In the meantime, eat something with lots of carbs (at least, that's what I would do because it sounds like that could be the problem).

Grim also mentioned that you may not be eating enough. I didnt mention anything because I dont know how much you're eating, just that the types of things you're eating are not a lot. That could be the problem too. Your body might have been constipated because it fears starvation / drastic calorie change... although I'm not sure why it's decided to just let it all go now.

Feel better hun, and I really stress visiting a clinic.
Hugs.

All of this is based on the assumption that you're just low on carbohydrates:

I would start incorporating more carbs in your diet, but again I really stress that I'm not a very good nutritionist and havent been in your situation. I never have a problem staying away from carbs 'cause I'm an addict ( ), but it seems the most logical thing to do??

If it's really making you feel terrible, I'd see if you could find any sort of painkillers that might make you feel a little better and start eating more carbohydrates (if that is in fact the problem) and try to ride out the hell your body is putting you through. Depending on your metabolism, if it is lack of carbohydrates that's making you feel so ill, you should start feeling better within 1-3 days... would be my educated guess anyway. If you're like me and avoid doctor offices as much as possible, if you dont feel better within that time frame, please see a doc?

Carbs are actually pretty good for you; the ones you want to avoid are the carbs that are white. White sugar, white bread, because you digest it really quickly and it's had all of it's grains stripped from it.

I do know that the diet I'm trying to follow right now is roughly 50% carbohydrates, 30% protein and 20% healthy fats. It's a combination I've seen all over the Internet and it's also in a book that I own that was written specifically for women ages 13-20 who want to become healthier. In the carb area, it includes breads, starchy veggies, and legumes as carbs, so if you want to stay away from breads, etc, stick with veggies perhaps? I just found this brand called Valley Fresh Steamers that you might like, although they're probably called something else in England...

Feel better hun, and I hope the problem is just a lack of carbs. It's not super serious, but it's something you should fix as soon as possible.

It could depend alot on what you ate, somethings are natural diaretics (I think I spelled that right). Coffee, cigarettes, etc. And then there are stool softeners and laxatives. Sometimes it's hard to tell what may soften a stool, and even if you don't knowingly take one some are naturally so.

So short answer to your question; yes a change in diet, especially a drastic change, can change your stool and make you ill, but really shouldn't.

Just be careful about what you eat, (good stool hardeners are proteins, so meat, fish, eggs) make sure to drink plenty of water because diarrhea can dehydrate. I know about that and laxatives, I took some to drastically lose weight once and it screwed up my insides something awful.

hope you feel better hun

Drink plenty of water and try to eat more fiber. That's all I can offer without knowing how you've "drastically" changed your diet.
