WHAT: 2012 Walk to Cure Diabetes Celebrating Ron Santo, a nine-time All-Star for the Chicago Cubs. Later in his career, he was a beloved broadcaster for the team.

Santo suffered from Type One diabetes for most of his life but kept it a secret because he thought it would prematurely end his baseball career if the team owners found out.

Members of Ron Santo’s family, residing in Arizona, will share Ron’s story. Type One diabetes was a huge part of Santo’s life and legacy as he was a great advocate for the cause. The disease eventually necessitated the amputation of the lower half of both legs.

Today in Tucson, there will be a 5 kilometer (3 mile) walk, inflatable bouncing castle, face painting, live entertainment, exhibitors, lunch and more.

While the cost to participate is free, fundraising is encouraged. The JDRF Desert Southwest chapter has set a fundraising goal of more than more than $200,00, which will help fund research toward preventing, better treating, and curing type 1 diabetes and its complications.

The JDRF, which used to be known as the Juvenile Diabetes Research Foundation, is the leading global organization focused on Type One diabetes research.

Type 1 diabetes (T1D) is an autoimmune disease in which a person's pancreas stops producing insulin, a hormone that enables people to get energy from food. It occurs when the body's immune system attacks and destroys the insulin-producing cells in the pancreas, called beta cells. While its causes are not yet entirely understood, scientists believe that both genetic factors and environmental triggers are involved. 

Symptoms include excessive excretion of urine, thirst, constant hunger, weight loss, vision changes and fatigue. These symptoms may occur suddenly.

Type Two diabetes is more common than Type One diabetes. While Type One is most commonly diagnosed during childhood, Type Two diabetes in children is rare.

Type Two results from the body's ineffective use of insulin and comprises 90 percent of people with diabetes around the world. Unlike Type One, Type Two diabetes is mainly the result of excess body weight and physical activity.
