I would like to share my experience with my both grandmother and grandfather.
I live in Egypt ( male 32 years old)which is a nice country by the way. I live in a city that is on the sea shore directly. I find it dramatically that the weather here is almost fine all the year. About caring of my grand mother and my grand father, it was a hell of experience.
First of all lets talk about my grandmother. She had never went to a doctor in her early life, but later when she got older she began to suffer from diabeted milletus which is a disorder of glucose metabolism that lead to hyperglycemia due to lack or resistance of insulin in the body. This disease need treatment with either insulin or oral hypoglycemic to decrease the rising blood sugar. In our country we call is in or language "sugar", this name refers to the pathology of the disease.
