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.
What causes blood clots (blood clots in veins or arteries)? Blood clots form when there is damage to the lining of a blood vessel, either an artery or a vein. The damage may be obvious, such as a cut or laceration, or may not be visible to the naked eye.
