Nausea

[ChrisCS]

Hi, I'm a 17 male and about 2 months now I've been having nausea every time after I eat. It started after I had the flu which made me vomit and caused a tremendous amount of pain in my back, I had no fever and just had a sore throat the week before the flu. The nausea now is causing me to lose my appetite, I feel somewhat weaker, and definitely have a weaker stomach (some days the slightest odors make me gag) . I'm not under any sort of emotional stress so I'm sure its not depression or anxiety, I also hike and camp (nausea or not), I'm positive that I haven't got a parasite in me . Carbonated drinks seem to help, i have no diarrhea, its all working fine down in that area. What tests should I expect if I go in and see a doctor? and what might i have?.
Thanks for your time.
Chris.

Chris - Check your thyroid. Make SURE they test TSH levels for the thyroid on you (blood test). Mention it to them because normally doctors do NOT check TSH levels for the thyroid. You could possibly have a thyroid disease. Also have them check for inflammatory bowel diseases as well. Check for Celiac disease (pronounced "see-lee-ack") , crohn's, and ulcerative colitis. Check for H pylori (a parasite) as well. Also try taking some Probiotics. Ask your doctor about them. It helps to go to the doctor prepared because they don't care about their patients usually. They go home at night nice and healthy and you go home sick :( so be prepared and don't be afraid to ask questions!

I'll do that, thank you.

Go to a GI doctor, ask to be checked for gastroparesis, which can be a complication of an infection.  The pain in your back could have been from your stomach. Expect a gastric emptying study. Carbonated drinks speed stomach emptying, so it isn't surprising they seem to help. I bet fatty foods make it worse (they slow stomach emptying). Small meals will probably work better until you are treated.
