Definition Bleeding refers to the loss of blood. Bleeding can happen inside the body (internally) or outside the body (externally). It may occur: Inside the body when blood leaks from blood vessels or organs Outside the body when blood flows through a natural opening (such as the vagina , mouth, or rectum) Outside the body when blood moves through a break in the skin Alternative Names Blood loss; Open injury bleeding Considerations Always seek emergency assistance for severe bleeding, and if internal bleeding is suspected. Internal bleeding can rapidly become life threatening, and immediate medical care is needed. Serious injuries don't always bleed heavily, and some relatively minor injuries (for example, scalp wounds ) can bleed quite a lot. People who take blood-thinning medication or who have a bleeding disorder such as hemophilia may bleed excessively and quickly because their blood does not clot properly. Bleeding in such people requires immediate medical attention. Direct pressure will sto...
Omega-3 fatty acids from fish oil have conclusively been shown to reduce risk for heart attack and stroke. They also have the capacity to "thin the blood."
What this means is that omega-3s slightly block the activation of blood platelets and inhibit their "clumping," two basic steps in clot formation. Omega-3s also inhibit production of arachidonic acid and thromboxane that trigger blood vessel constriction and inflammation. The blood clotting protein, fibrinogen, also an independent coronary risk factor when at high levels, is reduced by omega-3 fatty acids. Contrast these effects with that of obesity, sedentary behavior, and an unhealthy diet, all of which favor platelet activation, abnormal blood vessel constriction, and increased fibrinogen levels.
But can fish oil cause excessive bleeding ?
This question comes up frequently. In my cardiology clinic, we use moderate- to high-doses of omega-3 fatty acids to reduce triglycerides, correct inherited ca...
Bleeding time is a blood test that looks at how fast small blood vessels close to stop you from bleeding.
How the test is performed
A blood pressure cuff inflates around your upper arm. While on the cuff is on your arm, the health care provider makes two small cuts on the lower arm. They are just just deep enough to cause a tiny amount of bleeding.
The blood pressure cuff is immediately deflated. Blotting paper is touched to the cuts every 30 seconds until the bleeding stops. The health care provider records the time it takes for the cuts to stop bleeding.
How to prepare for the test
Certain medications may change the test results. Always tell your doctor what medications you are taking, even over-the-counter drugs. Drugs that may increase bleeding times include dextran, nonsteroidal anti-inflammatory drugs (NSAIDs), and salicylates (including aspirin).
Your doctor may tell you to stop taking certain medicines a few days before the test. Neve...
