Homocysteine Topic Guide
Homocysteine: Homocysteine is an amino acid produced by the body, usually as a byproduct of consuming meat, fish or dairy. Elevated levels of homocysteine in the blood do not usually cause symptoms, but they raise the risk for heart disease. The cause of high homocysteine levels is usually dietary deficiencies in vitamin B6, vitamin B12, and folic acid. Treatment to lower homocysteine levels is vitamin supplementation.
Pulmonary Embolism A pulmonary embolism (PE) is a blood clot in the lung. The clot typically comes from other areas of the body and travels to the lung, where it becomes lodged. Pulmonary embolism can cause serious problems, from shortness of breath to instantaneous death, depending on the nature of the clot.
