Have you tried a product called oxy powder? It’s a high dose of magnesium oxide for chronic constipation. What it does is it breaks down into a lot of oxygen, which causes the stool to loosen and easily leave the body. It also effectively cleans the lining of the colon and your body does not absorb any of the magnesium oxide. It’s been a lifesaver for me as I struggled with what’s called chronic idiopathic constipation. I can also recommend an online medical practice called IBS TREATMENT CENTER, they did a slew of tests which have determined that my condition is the result of a very very severe infestation of candida and other bacteria for which I am now being treated. I wish you the best and I hope you’ll try the oxy powder, I feel like I saved my life for the time being.
