There are many causes of loose stools, most of which are not serious. Most diarrhea illnesses are more of a nuisance than a medical problem and clear up easily with extra fluids and minor changes in the diet. The main concern with diarrhea is dehydration.
Blood Clot Symptoms. Symptoms of a blood clot in the venous system can include swelling of the affected area, warmth, redness, and pain. Venous blood clots occur most commonly in the arms and legs. Symptoms of an arterial blood clot result from a lack of or decrease in oxygen delivery to the tissues supplied by the involved artery.
Blood clots occur when blood thickens and clumps together. Most deep vein blood clots occur in the lower leg or thigh. They also can occur in other parts of the body. A blood clot in a deep vein can break off and travel through the bloodstream. The loose clot is called an embolus (EM-bo-lus).
