The Silent Killer New research and guidelines detect Type 2 diabetes in a much larger population. Diabetic Retinopathy Diabetes can affect vision by caus- ing cataracts, glaucoma and dam- age to blood vessels inside the eye. Diabetic retinopathy is a com- plication of diabetes caused by changes in the blood vessels of the eye. The retina is a nerve layer at the back of the eye that senses light and helps send images to the brain. When blood vessels in the retina are damaged, they may leak fluid or blood and grow fragile, brushlike branches and scar tissue. This can blur or distort the images that the retina sends to the brain. Diabetic retinopathy is the lead- ing cause of new blindness among adults. People with untreated dia- betes are 25 times more at risk than the general population. The longer a person has diabetes, the more the risk of developing diabet is retinopathy increases. Jack Adelman's ears are checked by Dr. Solomon Rosenblatt during a routine exam. RUTHAN BRODSKY Special to The Jewish News S ixteen million Americans suf- fer from diabetes and half of them don't know it. Indeed, next to hypertension, diabetes is the disease family physicians are most likely to encounter in patients over age 40. Jack Adelman of Farmington Hills never felt sick when he was diagnosed as having diabetic mellitus. "I was close to my 60th birthday and found myself craving sweets and running to the bathroom frequently. My internist reported that my blood sugar was high and I started to watch what I was eating. About seven years ago, when diet alone couldn't control the elevated blood sugar, I started tak- ing oral medication and today I'm working with a combination of med- ications. I've eliminated desserts and sweets and I exercise regularly. As a result I lost 20-plus pounds, which is saying a lot because I was the world's biggest nosher. I've become very disci- plined about my diet and exercise because, no matter the medication, that's a major factor keeping my dia- betes under control." Last July, the new guidelines for the diagnosis and classification of diabetes mellitus were published and, among other things, they included more fre- quent testing. Blood sugar levels previ- ously considered normal now call for a diagnosis of diabetes. As a result, another two million cases will be detected of this country's leading cause for blindness, kidney failure, and foot and leg amputation. Diabetes also was connected with close to 200,000 deaths in 1997. Diabetic symptoms develop gradu- ally and in the beginning are difficult to identify. Early diagnosis is impor- tant because the longer diabetes goes untreated, the greater the risk of com- plications. Until six months ago, the threshold for a diabetic diagnosis was 140 mil- ligrams of sugar (per deciliter of blood) after an eight-hour fast. Now the American Diabetes Association says a fasting blood sugar or glucose level of 140 may mean that a lot of damage has already been done — even if the person doesn't show any out- ward signs. The new, lower threshold is 126. "Type 2 diabetes mellitus, the more common form of the disease, is often called the silent killer because many with high blood glucose levels don't have major symptoms and the condi- tion goes unrecognized," says Dr. 1/9 1998 105
