Blood glucose or blood sugar is what helps supply the body with energy. However, maintaining a healthy blood sugar level is imperative in leading a healthy life. High blood sugar levels can indicate that you are suffering from a condition that impairs the body's ability to process blood glucose. Regular monitoring of blood glucose levels can even reduce the risk of heart diseases. A balanced, healthy lifestyle supplemented with Ayurvedic medicines for sugar patients, such as Karela and Methi, can help keep sugar levels in check.
