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.
Your risk of a blood clot can also be increased if you smoke or are overweight. Symptoms of having a blood clot include skin redness, swelling in only one leg, swelling or bruising behind the knee, localized soreness or pain, or having a warm spot on your leg. If the clot moves to the lungs you may experience shortness of breath, chest pains, a fast heartbeat, mild fever, or fainting spells.
