Hi everyone. I am new to these boards and came across them when googling symptoms. I have no idea if I am in the right place, but here goes!Last Oct. 2009 I was hit with what I thought was a horrible bout of the stomach flu. I had 2 weeks of non-stop diarrhea, couldn't keep anything in me for long without it passing through quickly. I was losing a pound a day and was very scared and anxious. Which Im sure didn't help my symptoms and weight loss. I felt horrible; heavy stomach sensation, nausea, no appetite, gurgling, etc. but no fever the entire time. My husband finally took me to the ER after us both being scared I had cancer! I had lost a total of 30 pounds! The ER staff did a CT, which came back normal. Blood panel was normal, stool culture for H pylori and parasites all normal. They sent me home w/diagnosis of diarrhea and referred me to a gastro doc and said I needed a colonoscopy. Things would get better stomach wise and then go back to feeling like I did before. I couldn't get a gastro appt until Jan. I went to my family doc while waiting for the gastro appt. and he sent me in for a pelvic/abd ultrasound and MORE blood work...all came back normal but I was low low low on vita D. Long story short..I finally saw my gastro doc, they did a colonoscopy and a endoscopy...both were fine. No polyps, cancer, H pylori, Celiacs, diverticulitis, etc. The gastro doc diagnosed me as post infectious enteritis with IBS. Due from eating contaminated food?He said I could have up to a year of symptoms....it's now May and I am getting the same symptoms back again! Stomach feeling heavy...nausea...appetite that comes & goes...gassy.. Has ANYONE gone through this? If so, can you shed some light on what I can expect? is something bad wrong with me? HELP! and thanks! I am also a 44 yr old female and was also told that it could possibly be perimenopause too!
