You Will Bleed Green under This Rare Medical Condition

Your blood is actually always red! Blood in your veins has very little oxygen and is a dark red colour that looks almost blue when covered by your skin. Your arteries have bright red blood because it has a lot of oxygen in it that is being carried throughout your body to be used by tissues.

Almost every other human being on earth might have gone through some minor or major cut on their body resulting them to bleed. Our blood, as a matter of fact is always red in colour.

Unfortunately, there are some people who actually bleed green only under some circumstances. Here, we bring to you an amazing fact on why, when and how can one bleed green.

Surgeons operating on a 42-year-old Canadian man got a shock when they discovered dark-green blood coursing through his arteries. Stunned, the medical team immediately sent his blood for analysis. The test revealed the blood discolouration was caused by Sulfhaemoglobinaemia, which occurs when a Sulphur atom gets incorporated into the oxygen-carrying Haemoglobin protein in blood.

Doctors suspected that the patient’s migraine medication caused the condition. “It is possible that our patient’s arguably excessive intake of Sumatriptan, which contains a Sulfonamide group, caused his Sulfhaemoglobinaemia,” they say.

 “The patient recovered uneventfully, and stopped taking Sumatriptan after discharge. When seen five weeks after his last dose, he was found to have no Sulfhaemoglobin in his blood,” they added.

The Canadian doctors explain that Sulfhaemoglobinaemia usually goes away as red blood cells regenerate. In very extreme cases a transfusion might be necessary.

Sulfhemoglobinemia is a rare condition in which there is excess Sulfhaemoglobin in the blood. The pigment is a greenish derivative of Haemoglobin which cannot be converted back to normal, functional Haemoglobin. It causes cyanosis even at low blood levels.

Sulfhaemoglobinemia, presence in the blood of Sulfhaemoglobin, the product of abnormal, irreversible binding of Sulphur by the Haemoglobin in the red blood cells, rendering them incapable of transporting oxygen. The condition may result from the chronic use of such drugs as Acetanilide and Phenacetin.

According to doctors, the patient’s migraine medication was the main culprit behind this condition. “It is possible that our patient’s arguably excessive intake of Sumatriptan, which contains a Sulphonamide group, caused his Sulfhemoglobinaemia,” they say.

In other conditions, if you cut yourself almost 30ft underwater, you will gradually bleed a bright emerald green. This is because there is no red light in water. However, if you move even deeper, the blood will change its colour from green to black.
