Hi
Welcome to the forum!
The nausea can also be due to internal ear problems, poor sleep pattern, stress, overwork, anemia, kidney problems, high blood potassium levels, abnormal pancreas function, diabetes, Addison’s disease, Crohn’s disease, gluten or lactose intolerance and taking coffee. Other tests have been done for you. The enumerated the possibilities can be investigated or ruled out one by one by your physician.
Please let me know if there is any thing else and do keep me posted. Take care!
Bummer. Well, have you tried tums, you know stuff like that? Might sound too simple, but it might work. When I was sick to my stomach all the time, they found an ulcer. What kind of sickness is it? Does it feel like burning and bile coming up? Could it be from stress??
