Unleash your own d-senses
A Diabetes Alert Dog provides an invaluable service to a person with diabetes and their loved ones. The keen senses animals possess are refined into an early warning system which can alert a person or others around them to blood sugar levels drifting into the extremes of high or low. These animals primarily use their sense of smell, but their vision might also contribute to their uncanny abilities too. But human beings also possess a formidable array of senses which, properly harnessed, can be powerful tools to avoid certain diabetes care related catastrophes. I will explain. Insulin preparations have a distinctive smell, some might say odor. This smell comes from the preservatives (metacresol and/or phenol) and is not the insulin itself. Metacresol and phenol are what are known as "aromatic" hydrocarbons. The aroma of these agents is quite distinct.
