Diarrhea for 2 weeks?!

Diarrhea for 2 weeks?

I have had diarrhea for over 2 weekx now. some minor cramping, otherwise just weak but ok. what is it?
diarrhea is mostly liquid, light brown to yellow clear no real solids. some nausea and very weak, drinking lots of water. very afraid to eat...ANYTHING, and losing appetite. there is some minor cramping and some nausea but thats it. I am post menapausal so i am not pregnant....that's out. is there some virus out there that is "going around" that does this? I went to the DR. they ran tests on blood and stool samples and nothing was found. Any ideas? This is getting scary and I can't go any where (work etc) Help if you can

If your labs have come up with no virus, and it seems like you don't want to eat just so you don't go bolting to the restroom. Try the B-R-A-T diet for a while. Your bowels or digestive tract may have been irritated. this can be caused by different new foods or by changes in medication. The Brat diet is easy B-bananas - R-rice - A-applesauce - T-toast. These are all easily digested and the starches should help. If you are drinking just water, be careful. While replacing some liquid your body is using, the diarrhea is flushing most of it back out, (since water is re-absorbed through your intestines first,) Have a friend get pedialyte for you. It doesn't matter how old you are, it is great for replacing elecrolytes that can add to your feeling weak. Stay away from Strong juices like orange, grapefruit juice. If you drink apple juice dilute it. the acids and sugars will only aggravate your bowels. Also, avoid coffee and tea, they are natural diuretics and will only add to the problem. Also look for over-the-counter anti-diarrheah medication. if the "pink stuff" isn't working, ask your pharmacist for the next 'step up'. be sure to consult your doctor if you are taking additional meds.
