I found that my irritable bowel condition cleared up entirely after treating myself about 6 months for Pyroluria. Here is a copy of a previous post to someone who was not sure Pyroluria is real, hope you find it helpful.
Hope your child improves.
Pyroluria is a "medically unrecognized" but very real disorder & easily provable as real. In my opinion, & there is good evidence, it has been ignored, dismissed, & suppressed since it's discovery in the early 1960's because it explains & leads to inexpensive natural treatment for a large number of highly profitable disorders from ADHD, Panic, Phobia, to Alcoholism, eating disorders, & Osteoporosis.
One must remember that the huge Medical/Pharmaceutical industry is a business whose first priority is making money, second is controlling health information & regulation, & third is helping sick & injured people.
While individual health practitioners can be warm & noble minded individuals, in all organizations, the higher up you go in the pyramid of authority, the more decisions are based on Corporate & Industry profits & less on what is best for the peasants below.
The never ending scandals in politics, big business (Banks), & most recently with Mr Murdoch illustrate this well.
The good news is that Pyroluria is definitely Not genetic, but a (poor) diet/weakened & immune system- initiated, multi-resistant Infection which is easily treated & slowly reversed with vitamins & inexpensive natural foods. One can feel, or even more easily observe in another, a calming of anxious feelings & behaviors such as ADHD, obsessiveness, Phobia, & even the strong urge to self medicate uncomfortable feelings with food, sex, alcohol, or shopping, in less than One Hour.
Research well Pyroluria symptoms & Pyroluria Infection on your own for the health of your family, because Drs are not taught inexpensive natural remedies that interfere with the Almighty Revenue Stream.
