Vomiting. Abdominal blood clots irritate the stomach lining, and the body responds by vomiting. Diarrhea. Lack of blood supply alters the function of the digestive system and often leads to diarrhea. Bloody stool. Any irritation to the linings of the digestive system can cause bleeding. You may therefore notice blood in your bowel movements.

Swelling. When a vein is blocked, it will cause fluid retention and swelling in the area of the clot. Tenderness. In addition (or instead of) sharp pain, you may have a general discomfort or tenderness in the area. This happens because of the inflammation in the area. Discoloration. The clot blocks blood supply to the area, so the skin of your arm or leg may become bluish or red. [3] X Research source A sense of warmth. When inflammation occurs, the body increases blood flow to the damaged area. The blood carries body heat from the core of the body, causing a warm sensation in the affected area.

Visual disturbances. Weakness. Paralysis. Seizures. Speech impairment. Disorientation.

Clots in the heart can lead to life-threatening problems, such as a heart attack.

Rapid pulse. The heart compensates by beating fast in order to supply sufficient blood to the body. As a result, your pulse rises. Bloody cough. A clot can irritate your lungs, causing bleeding. You may cough up blood. Shortness of breath. A clot can block the passage of air in your lungs, leading to difficulty breathing.

Extended travel in an airplane or car can minimize muscle movement, increasing the risk of blood clots forming in the veins.

Cancer. Liver disease. Kidney disease.

Ultrasound. Using an ultrasound machine, your doctor may be able to detect the formation of blood clots in the veins. Venography. In venography, a contrast dye is injected into a small vein in your hand or foot. Using fluoroscopy, the doctor can then observe the path of the dye, looking for possible clots. Arteriography. In arteriography, a dye is injected directly into an artery. Similar to venography, arteriography will allow your doctor to observe the path of the dye and confirm the presence of a clot.

Chest x-rays. X-rays cannot detect the presence of clots. However, they can reveal some conditions, triggered by clots, that lead to chest pain and shortness of breath. Electrocardiogram (EKG). An EKG is a painless test. It simply records your heart’s electrical activity, revealing abnormalities associated with a pulmonary embolism. Computerized tomography (CT) scan. In a CT scan, a contrast dye is injected into a vein, and your lungs or brain are scanned for signs of clots. [17] X Research source Cerebral Angiography. This test involves a catheter, x-ray imaging and an injected contrast dye to get clear images of blood vessels in the brain. [18] X Research source Carotid Ultrasound. This painless test images the carotid arteries with sound waves to look for blockages or narrowing, which can increase the risk of a stroke. [19] X Research source Ventilation perfusion. Ventilation perfusion is a test in which a chemical is used to identify air inhaled into the lungs. This is then compared with the blood flow in the arteries to reveal the presence of a pulmonary embolism.

Thrombus. A thrombus is a blood clot that develops in the veins or arteries. Embolus. An embolus is a thrombus that has moved from the bloodstream to another location. Deep vein thrombosis (DVT). DVT is a common and dangerous clot, usually formed in a major vein in the leg (though sometimes also appearing in the arms, pelvis, or other parts of the body). It blocks blood flow and causes pain and swelling.

Enoxaparin (Lovenox). Enoxaparin is a medication injected to thin the blood immediately. The typical dose for adults is 40 mg injected into a fatty area of the body, such as the arm or abdomen. Warfarin (Coumadin). Warfarin is an anticoagulation pill, which acts as a blood thinner. The dosage depends on the particular patient. To determine the dosage and administration, your doctor may perform a test for blood clotting known as the International Normalized Ratio, or INR. Heparin. Heparin is a traditional anticoagulant medication, given intravenously to prevent the growth of blood clots. The dose depends on your particular circumstances; your doctor should perform blood test measurements to determine dosage.

Cardiac catheterization. For blood clots in the heart, cardiac catheterization is performed to locate the clot. A balloon is inserted to open the blockage, and then a stent is placed to keep the appropriate vessel open. The pressure from the balloon and the stent breaks the blood clot into smaller pieces, restoring the flow of blood.

A catheter-directed thrombolysis is a surgical procedure in which a catheter is inserted directly to the blood clot, releasing medication to dissolve it. [23] X Research source Thrombectomy. A thrombectomy is simply the surgical removal of the blood clot itself. It is often performed with thrombolysis is ineffective, or when there is an emergency condition requiring immediate treatment.
