[Poisonous tongue]Excessive blood loss and drinking a lot of water can be fatal?Deconstructing the crisis of “hypotonic dehydration” in 2 steps to deal with bleeding – Hong Kong Economic Times – TOPick – Health – Doctor’s Consultation

The recently released Lunar New Year movie “The Poisonous Tongue” and the classic movie “Chariots of Fire” both mentioned that in the case of excessive blood loss, drinking a lot of water is enough to kill. What is the reason? What counts as “massive bleeding”? Registered Chinese medicine practitioner Ma Qijie recently explained on his Facebook page that drinking water after massive blood loss can cause “hypotonic dehydration”, and taught 2 correct steps to deal with bleeding after a serious injury.

Ma Qijie, a registered Chinese medicine practitionerFacebookShared, invariably mentioned “The Poisonous Tongue” and “Chariots of Fire”, there are plots in which someone drank a lot of water after losing too much blood and died. He explained that if the human body loses too much blood (more than 500cc in an adult in a short period of time, about 15% to 20%), it is a physiological reaction to be severely injured and thirsty.

However, if you drink a lot of water when you lose too much blood, it will reduce the blood concentration and greatly reduce the number of red blood cells. When the red blood cells are less than 30% (normally 50%), it will affect the blood oxygen content, so that the blood cannot provide enough oxygen to different organs.

In addition, if you drink a lot of water, the diluted blood will become hypotonic, which will cause more water to flow out of the tissue; then it will cause “hypotonic dehydration”, which will cause irreparable damage to important organs, such as the brain, liver, heart, etc. trauma.

Ma Qijie pointed out that after a large amount of blood loss, one should be careful not to allow the seriously injured to drink water and call 999 immediately. And if you really want to drink water, you can only drink a small amount of “salt water” and wait for an ambulance to come.
