Poll:- Do Leeches Really Suck Blood?

yes those ugly looking suckers leave love marks all over the body.

Oh yes they do!!!

They suck blood for food, now this may sound disgusting but you can get health benefits from letting leeches suck your blood..

They produce several important substances that make its bite very special, including an anticoagulant (hirudin), a local vasodilator, and a local anaesthetic. These substances allow continued bleeding that mimics venous circulation for up to 10 hours after the leech has detached (and the anaesthetic makes the bite painless). The leech can also remove any congested blood to allow normal circulation to return to the tissues and prevent gangrene from setting in.

Leeches may also be used to treat black eyes. And hirudin, the anticoagulant, may be used in the treatment of inflammation of the middle ear. Hirudin may also eventually be used in invitro blood sampling. Researchers have found that the anticoagulant and clot-digesting properties of substances in leech saliva make them potentially useful for the treatment of heart attacks and strokes.

hope that my answer helps you..

Yes, they do, but not like a vampire would suck your blood. If a leech is on you long enough you would form a hickey like mark where they sucked. A 1000 of them sucking at once could be a problem.

Yes, the doctors attached a few to my friends finger after an accident to help get the blood flowing to the tip of his finger. It worked. He still has the finger. They were going to have to amputate it if the leeches didn't work.

Yes, indeed they do.They are still being used by hospitals today.The plastic unit at a hospital near me use them.They help to draw the blood to the area of skin that has been cut from another part of the body in order to stimulate the blood flow.

Yeah leeches really suck.
