I came to the appointment with complaints of intestinal pain and digestive problems. The doctor asked whether I get carsick. I answered that I have been getting carsick all my life. Then he said that my gallbladder was blocked, toxins were accumulating, and he called it rubbish. To my question about what this rubbish was, there was no answer. I had an abdominal ultrasound and came back. I was told that the gas in my intestines was due to parasites. I asked where the parasites could come from if I only eat home-cooked food that has been heat-treated and drink clean water. In response I heard that Helicobacter can be transmitted through saliva, and it could also be giardia.
