American Diabetes Alert Day is observed annually on the fourth Tuesday of March and this year, it falls on March 28. It is aimed at raising awareness about the risks and symptoms associated with diabetes among the American public. The holiday is sponsored by the American Diabetes Association. Diabetes occurs when the body’s blood glucose level is too high. This is caused by a deficiency in the insulin produced by the body, which is the hormone that lets glucose enter cells and be used as energy. Excess glucose in the blood can lead to several health problems. The most common types of diabetes are Type 1, Type 2, and gestational diabetes.
