I am completely intrigued by this illness/condition that I just learned about. Like oxalates, which I wrote about here, it’s not widespread and known by everyone.

It’s insane how the description of Pyroluria seems to describe me with the exception of a few symptoms.

I’ve been diagnosed with adrenal fatigue and surprise, surprise, Pyroluria is related to it. Also related to leaky gut, candida, and a host of other issues.


Pyroluria is a blood disorder first and foremost. 

Hemoglobin is a particular protein whose job it is to keep and maintain iron in red blood cells. Because of an abnormality in the synthesis of hemoglobin, a by-product is created called kryptopyrrole, known scientifically as hydroxyhemoppyrrolin-2-one (HPL).

This is the chemical that is involved in the production of heme, the substance that causes blood to be red in color. In most humans, HPL causes no problems and is simply excreted from the body via the urine.

With pyroluria, the level of pyrroles/HPL in the blood is abnormally high, and as a result, the receptor sites for Vitamin B6 and zinc are bound up and blocked. Kryptopyrroles target aldehydes in order to bind to them, and specifically targets pyridoxine (Vitamin B6). 

Together they attach to zinc, which creates a complex that is ultimately eliminated through the urine. If there are excessive binding and excretion out of the body, Vitamin B6 and zinc may be deficient.

Zinc and B6 are essential for the production of neurotransmitters such as serotonin (our happy hormone), melatonin (our sleep hormone), GABA (our calming hormone), and acetylcholine (our housekeeping hormone).

They are also involved in the production of our steroid hormones such as cortisol (our anti-stress hormone) and the conversion of oils in the body (fat metabolism, liver, gall bladder issues, and weight control). (source)

Essentially, the body doesn’t properly process B6 and zinc, and you are left with a severe deficit which impacts much of the body’s responses to stress.  People who have leaky gut (hi!) are very likely to have Pyroluria. 

Like  I have said before, health issues can fall like dominoes. Leaky gut and adrenal fatigue especially can lead to a cascade of other problems.

“Pyroluria falls outside the realm of mainstream medicine because the only way to rectify the problem is by improving the sufferer’s nutritional status, diet, digestion, and stress levels. Mainstream medicine relies on drugs to suppress symptoms or relieve suffering.

This form of treatment won’t work for a person with Pyroluria and sadly these Pyroluria sufferers tend to fall through the cracks of mainstream medicine and are often misdiagnosed and given medication that does nothing to rectify the underlying problem.” 


When I began researching this condition, I was shocked how many other issues were connected to it including anxiety disorders, depression, bipolar disorder, and so much more.
