How much blood can a human drink before getting sick?

In: Conditions and Diseases [Edit categories]

Answer:

A minuscule amount of blood --less than a drop, can carry and transmit an unbelievable amount of disease and bacteria, among which are hepatitis, AIDS, Malaria, even STDs (sexually transmitted Diseases). SO, forget about a stomach ache- which is almost certain to occur when drinking raw blood, there are many other worse things that can happen. I would strongly advise against this. However, it is important to note that many, many people drink blood regularly. And no, they aren't freaks or vampires. If a person has severe and common nosebleeds, they often consume a lot of the blood. When a person gets a nosebleed while they are sleeping, blood may seep down their throat for several minutes before they wake up. I have never seen a person vomit after a nosebleed that began while sleeping and I know from personal experience that it is more than possible to sleep through a nosebleed and not experience any negative after effects. Blood, or rather YOUR blood, isn't toxic; but a lot of people who drink their own blood (not on purpose, of course!) will get sick because the idea of drinking blood is disgusting to them.

It only takes a little blood in the stomach to make a person sick. Seeing as though there are no definitive and here is a movie quote. The actual validity of this quote isn't proven and is presented as is.'You can swallow a pint of blood before you get sick." -Edward Norton's character "Tyler Durden' from an undisclosed copyright protected movie. (Fight Club)

It really depends on the person. Some people get sick very easily after swallowing only a small amount, others take more. However it is a fact that the human digestive system does not like blood. It is very irritating to the mucosal lining of the digestive tract. I would recommend NOT drinking any blood if possible.
