Ok this may sound weird, I too had similar symptoms and was sent to a GI dr. She did some simple tests and the put me under and did a endoscope and a colonoscopy. They checked for crohn's disease, looked for cancer and took samples of every organ. I ended up contracting a disease that I should have received from a 3rd world country ( which I hadn't been to). I ended up having this disease called eosinophilic gastroenteritis.

What are the Symptoms of EGID?
Symptoms vary widely, depending on the area affected.
Symptoms include:
• Nausea or Vomiting
• Diarrhea
• Failure to thrive (poor growth or weight loss)
• Abdominal or chest pain
• Reflux that does not respond to usual therapy (which includes proton pump inhibitors,
   a medicine which stops acid production)
• Dysphagia (Difficulty swallowing)
• Food impactions (food gets stuck in the throat)
• Gastroparesis (Delayed emptying of the stomach)
• Anorexia (poor appetite)
• Bloating
• Anemia
• Blood in the stool
• Malnutrition
• Difficulty sleeping

Since none of these symptoms are specific for EGID, and many occur at times in healthy children or adults, the diagnosis is generally sought only after the symptoms have failed to resolve. Eosinophilic disorders can mimic the symptoms of other diseases like inflammatory bowel disease, food allergies, irritable bowel syndrome and reflux, among others.
