Diabetes Services

Diabetes is often considered a silent killer.  It is the fifth deadliest disease in the United States and the leading cause of adult blindness, kidney failure, and amputations, as well as the leading contributor to heart attacks and strokes.  In 2011, it was estimated that 25.8 million people living in the United States had diabetes, approximately 8.3 percent of the population.  In California, there are an estimated 3.7 million people with the disease, meaning that more than 1 out of 7 adults Californians has diabetes. From 1998 to 2007, the prevalence of diagnosed diabetes in California rose from 5.5 to 7.6 percent, representing a 38 percent increase in one decade.

Studies show that staying within one’s target blood glucose range, even half the time, can result in both immediate and long-term benefits. Proper self-management and control of blood sugar levels can significantly delay or prevent complications, helps develop coping skills for living with diabetes and improves the quality of life for persons with diabetes.

The Barragan Story

The Hazel Hawkins Hospital Foundation received a significant charitable donation in order to establish what will be known as The Barragan Family Diabetes Center. The gift was made by Mrs. Mary Ann Barragan, long time resident of Hollister, California, in memory of her husband, Ray who suffered from diabetes for many years.

Mrs. Barragan noted, “Ray faithfully believed that nothing was impossible. He would say the phrase ‘I can’t’ really meant ‘I choose not to.’ In honoring him, our family is saying ‘we can’ help residents in San Benito County who have been diagnosed with the disease. I have many friends and family members with diabetes and this is the one way I can support them.”

Current data indicates that 12% of the adult population in San Benito County has diabetes. An estimated 47% of the adult population is considered pre-diabetic or at risk of becoming diabetic. That is over half of all adults living in San Benito County. This generous gift to establish The Barragan Family Diabetes Center will allow the Hospital to better serve community members suffering from the impacts of diabetes-related health issues. The center will include wound care, and will be the first and only of its kind in San Benito County.
