Hyperhomocysteinemia is a medical condition characterized by elevated levels of homocysteine, an amino acid in the blood. High homocysteine levels can result from genetic factors, dietary deficiencies, or certain medical conditions. It is often associated with a lack of vitamins B6, B12, and folate, which are essential for breaking down homocysteine in the body. This condition is significant because it has been linked to an increased risk of cardiovascular diseases, including heart attacks and strokes. Monitoring and managing homocysteine levels through diet or supplements can help reduce these risks and promote overall health.
