bowel habits, lightheadeness, weight loss (anxiety or something else?)

Male/23
Symptoms:
- Wake up EVERY morning w/ strong bowel urgency, 99% of time loose stools. Sometimes blood on toilet paper w/ pinching feeling as stool released. Going on for 3 yrs, incidentally after being treated 4 sinus infection with antibiotics.
- Unexplained weight loss. Currently ~ pound/day for the last week, but have seen other times in the past few yrs that I have lost weight. Only started measuring at work daily the last week so this may have been happening longer.Still have good appetite.
- Constant lightheadedness/slightly off balance, started a few months ago. No real pattern, it is always there from morning til night, sometimes more intense, sometimes less.
- Tested with: digital rec. exam, 2 upper GI series, lower GI barium enema, 2 CBCs, sigmoid, stool culture for parasites, abdominal x-ray.
- history of stomach ulcers, but didn't really have common ulcer symptoms.
- blood on toilet paper probably due to fissures (told by gastro)
- bowel habits and lightheadedness attributed to anxiety by GP. I do feel anxious alot, but i thought it was mostly from these health issues, a paradoxical situation? Did my anxiety about my previous bowel problems manifest into the newer problems?

concerned i may have following conditions:
- Celiac disease
- Hyperthyroidism (i've heard that premature graying hair is an early sign, i've had grays since grade 4, but mother also grayed early)

Since all of your bowel workups have proved negative, it is most likely that the anxiety you experience is also effecting your bowels, and that your worries are compounded by bowels.  I would recommend a good course of therapy to get to the source of your anxieties.

i'm no doctor, but anxiety can mimic anything.  in the past month, i have had multiple sclerosis, diabetes, a heart attack, allergic reaction to medicine, etc... if your test come back negative you are fine. stop thinking. forget it. sometimes it helps me to talk to anxiety like its your *****.  "come on punk, is this all you got?  i can fix whatever you can throw.  this ain't nothin', it don't hurt."

Did you get your thyroid tested?    a wonky thyroid can mimic many of these symptoms.
