Re: parasites and nausea
Hello - not to frighten you, but this does sound like ascaris or hookworms to me. The adults live in the small intestine and the larvae live in the lungs in both species. Nausea is your body's natural way of trying to get rid of what's making it sick. When folks injest something that's harmful, the body goes into rapid defense mode which includes nausea, vomiting and diarrhea.
The toxins from the parasites are making you sick - your body is signaling you of their presence by the nausea. Hookworms can make a person VERY anemic because they hook into your intestional walls and drink your blood. These also can cause leaky gut from the holes they leave in the intestional wall. You may have both - ascaris worms grow larger (up to 1 foot) and can be more easily felt than hookworms. Here is the info from the HUMAWORM website about hookworms:
"HOOKWORMS – are also called “Necator Americanus” which means the American Murderer. They come from contaminated food and water. The eggs hatch in the intestines then migrate to the lungs through the bloodstream where they are coughed up and swallowed. They then travel back to the small intestine to reproduce. In the lungs they can cause pneumonia . In the intestines they hook themselves into the intestinal walls where each one drinks up to 1cc of blood per day causing bleeding and tissue death, not to mention anemia weakness. Hookworms from dogs and cats penetrate human skin and stay there causing skin problems and rashes including edema. (We get these from pets licking us or us petting or grooming them.) Hookworms also cause asthma, eye pain, insomnia, and dry skin and hair."
