Answer: Blood clots happen because normal blood flow is necessary to supply oxygen to organs and extremities and to carry carbon dioxide away from these tissues, damage to a blood vessel could jeopardize life sustaining functions by allowing blood to leak out
Answer: A blood clot can cause your leg to swell, become sore or painful (especially when walking), the skin can get red, and you might have a warm spot on it somewhere. Some blood clots can break off or move around, which can be very dangerous. If a blood clot reaches your lungs, your symptoms can be that of it being difficult to breathe, chest pain, a fever, cough (with or without blood in it), rapid heart beat, and you might faint easily or have fainted several times on a row or within a short amount of time from each one.
If you have any symptoms of blood clots, seek help as soon as possible!
Answer: It depends where it is. You might feel a localized sharp pain in the affected area . Usually if something is occluding your head or neck, you will feel pain and pressure in your head like when you are at an unusually high elevation.A deep vein thrombosis in your legs, especially behind your knee is VERY painful and persistent. Do NOT rub these things. You can break them loose. If you suspect this, please see a doctor or go to the ER.
Answer: Heparin inhibits the conversion of prothrombin (protein present in normal blood required for blood clotting) to thrombin (protein important for blood clotting), thus preventing formation of a thrombus (stationary blood clot).
Answer: Calcium is necessary for the normal blood clotting mechanisms that begin the process of wound healing.Good sources of calcium include dairy products, such as low fat and non fat milk, low fat cheese and lowfat yogurt are good dietary sources of calcium. Vitamin D fortified milk is the only reliable dietary source of vitamin D, a nutrient essential for calcium absorption.Vitamin K:The primary function of vitamin K is to regulate normal blood clotting. The vitamin is important for the production of prothrombin, a protein essential for blood coagulation.Vitamin K is found in green or leafy vegetables, such as broccoli, turnip greens, romaine lettuce and cabbage. Cheese, egg yolk, and liver contain small amounts of the vitamin.large doses of vitamin K can be toxic and supplements of this are available through prescription only.Large doses of vitamin E might interfere with the blood clotting functions of vitamin K.Deficiency in vitamin K is rare except in newborn infants, the vitamin is synthesized by microorganisms in the mature intestinal tract, but the establishment of bacteria takes days to weeks for newborns.There are also medications that affect the vitamin K absorption such as coumarin, warfarin,heparin, and salicylates. Liver disease and and malabsorption syndroem would also affect vitamin K absorption. these conditions require therepeutic doses from a physician to control.
