I've had the same symptoms for years, and I've been running a few test, like colonoscopy and biopsy. I was told that the result is negative, which made me happy and to keep going with a detox diet. However, even after the detox diet I am not feeling any better and I need to know what other test I can run. My symptoms are: loss of appetite, dizziness, nausea, bloating, stomach cramps, constipation, fatigue, deficit vitamins (D especially), black stool with occasional blood, back pain. Thanks in advance for reading my email. Kind Regards. Sophie.
