On October 13, 1972, Uruguayan Air Force Flight 571 crashed in the Andes mountain range.

Out of 45 people on board, only 16 survived after spending 72 days in the mountains under very harsh conditions.

Recently, Netflix released the movie The Snow Society, which recounts this shocking story.

One aspect of the film that caught viewers’ attention was that one of the characters began to notice that their urine was black. What could be the reason for this?

Urine should be yellow

Under normal conditions our urine should be light yellow.

When it is any other color, that’s a bad sign and a cause for concern.

In The Snow Society, the character Numa Turcatti (played by actor Enzo Vogrincic) notices that he has black pee.

This could be due to the extreme dehydration suffered by both him and his companions. It’s worth noting that he refused to eat human flesh.

They melted snow for water

All of the Andes survivors melted snow for water.

However, the amount they drank per day did not meet the recommended liter and a half.

As the days went by, their urine became more concentrated and it began to turn black.

Numa and his companions could have also suffered from rhabdomyolysis, which can occur when a muscle is damaged due to an accident.

Other reasons for black urine

El Mundo gives other possible reasons why the Andes survivors’ pee turned black.

One of them, although unlikely, is melanuria, which is when melanin is expelled through urine, causing a dark brown color.

Another possibility could be due to severe urinary tract infection.

Finally, there is choleuria, which occurs due to the expulsion of bilirubin, a yellowish pigment generated by the breakdown of red blood cells.

What is alkaptonuria?

According to El Mundo, it is unlikely that the Andes survivors’ pee turned black due to alkaptonuria.

That is a hereditary disorder also known as ‘black urine disease.’

It affects one in every 500,000 people and it is caused by the defective accumulation of homogentisic acid.

This causes an excess of pigment within the body, in the blood and tissues as the body stores more proteins than it should.

Urine begins to resemble the color of Coca-Cola

According to El Mundo, people with alkaptonuria do not excrete the proteins they should in the urine.

These proteins accumulate in both cartilage and bones.

For this reason, the urine turns black, resembling Coca-Cola.

It is important to note that it is unlikely that the Andes survivors’ pee turned black due to this condition.
