Blue is a colour that as a general rule few organisms are capable of generating, mostly insects. But if we tell you that there was an American family that had that colouring of skinDo you believe it? Well, we’ll explain what methaemoglobinaemia is.
The Fugate Family
The Fugate family, originally from Kentucky in the United States, consisted of several family members with this condition. genetics recessive, having blue skin. It all came about when Martin Fugate and Elizabeth Smith, both carriers of the gene recessive of methaemoglobinaemia formed their family and had children who were born with blue skin.
Methaemoglobinaemia occurs when the blood a person’s blood has a high concentration of methaemoglobin. This causes the blood not to carry the oxygen enough oxygen to the rest of the body and the skin turns blue. Sufferers usually have major health problems, but others are hardly affected at all.

Moreover, this condition does not generate any pathology The last member of the Fugate family was Luna Fugate, who lived for 85 years and had 13 children, but none of them were born with this pathology. In addition, the rest of the descendants of the family also had no offspring with this condition.
The Blue Men of Lurgan
In this case, two Irish brothers were also born with this pathology, but luckily, Dr. James Deeny managed to find a treatment with ascorbic acid and potassium from sodium with which he was able to reduce the sodium ions of iron ions of the methaemoglobin, which reoxygenates the blood of both in less than a month, thus losing the blue colour. Nowadays this pathology is treated with treatments based on the same principle using methylene blue.
Paul the blue
This person’s case is not a genetic disease but the same condition, as methemoglobinemia can be caused by intoxication with silver or nitrites which can also turn the skin blue.

Paul Karason, also an American, after ingesting colloidal silver developed Argyria turning blue. In the old days it was very common to take this type of silver as a remedy for bronchitis and pneumonia.

I’m impressed, I have to say. Really not often do I encounter a blog that’s both educative and entertaining, and let me let you know, you’ve gotten hit the nail on the head. Your thought is excellent; the difficulty is one thing that not sufficient individuals are talking intelligently about. I am very pleased that I stumbled across this in my search for one thing regarding this.
