What is deep vein thrombosis? Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein, usually in the legs. Clots can form in superficial veins and in deep veins. Blood clots with inflammation in superficial veins (called superficial thrombophlebitis or phlebitis) rarely cause serious problems. But clots in deep veins (deep vein thrombosis) require immediate medical care.
Diagnosing Exhaustion. Symptoms of physical and mental exhaustion include feeling constantly tired and worn out. Feeling physically and mentally exhausted can take their toll at all levels of life. We become less adept at our jobs, our relationships suffer, and energy levels drop to all-time lows.
Fatigue can be a less commonly recognized heart attack sign in women. According to the American Heart Association, some women may even think their heart attack symptoms are flu-like symptoms. A heart attack can cause exhaustion due to the extra stress on your heart to try to pump while an area of blood flow is blocked.
