Like "At age 27, I lost 13 pounds in two weeks (going from 120 lbs to 107 lbs), was constantly thirsty and urinating to the point where I was getting up every 5 to 10 minutes at night. I had grown up with a diabetic Dad in the 1950's-60's and he always had literature about the warning signs of diabetes, so I suspected that what I had when I saw my doctor. He did order a Glucose Tolerance Test at that time (1976). Because I was an adult, he initially tried diet and exercise but within a week or 2, I started using insulin."
