Fast Fact
A fasting blood sugar at or above 126 mg/dL or a random blood sugar at or above 200 mg/dL is diagnostic of diabetes, according to the official American Diabetes Association definition.
A fasting blood sugar of 100 to 125 mg/dL or a random blood sugar between 140 to 199 mg/dL is diagnostic of prediabetes, according to this same definition.
Prediabetes occurs when a person's blood glucose levels are higher than normal but not high enough to be diagnosed with type 2 diabetes.
The name, diabetes mellitus, comes from the Greek words for "to flow through" and "sweet." The Greek physicians used to diagnose the condition by actually tasting the urine. (That's dedication!)
Normally, a hormone called insulin pushes sugar from the blood into the body's cells where it can be used for fuel. The concentration of sugar in the blood remains within a fairly narrow range. If the body stops making insulin (type 1 diabetes), then adequate sugar doesn't get into the cells.
Until June 23, 1997, type 1 diabetes was also called insulin-dependent diabetes mellitus (IDDM).
Without insulin, muscle and fat begin to be burned for fuel (evidence of this -- ketones -- shows up in the urine). The person feels hungry all the time, but loses weight in spite of increased eating. Without replacement insulin, the person would eventually starve to death. Meanwhile, the concentration of sugar in the blood begins to increase. When the level reaches around 180 mg/dL, the sugar begins to spill over into the urine. This causes the person to make more urine and then to get thirstier, creating an accelerating cycle.
The classic symptoms of type 1 diabetes are increased urination (polyuria), increased thirst (polydipsia), increased eating (polyphagia) and weight loss. Anyone with the classic symptoms should have a blood sugar test as well as a urine test.
Occasionally people also report fatigue, blurred vision, vomiting, abdominal pain, or frequent skin infections.
If the disease remains undiagnosed, symptoms progress to include labored breathing, coma, and death.
People who get type 1 diabetes were born with a genetic predisposition to it. Not everyone born with this predisposition gets diabetes, however. In fact, if an identical twin has diabetes, the other twin gets it only about half the time.
Along the way, some of the predisposed individuals are exposed to something in the environment that triggers the diabetes. This is usually a viral infection. The virus misleads the body's immune system into making antibodies against its own pancreas cells that make insulin. (This is why type 1 diabetes is now also called immune-mediated diabetes.) The insulin-producing cells of the pancreas are gradually destroyed over time. When 90% of them have been destroyed, the person suddenly begins to develop symptoms.
Immune-mediated or type 1 diabetes most often strikes young people, especially between the ages of 5 and 7 (when viruses run through the schools), or at the time of puberty (when so many hormones change). For this reason, it used to be called juvenile-onset diabetes.
About 0.4% of the general public (or one out of 250) will eventually develop type 1 diabetes.
According to the National Diabetes Information Clearinghouse, just over 175,000 children under age 20 in the United States have diabetes.
About 800,000 people in the United States now have type 1 diabetes.
About 30,000 people develop type 1 diabetes each year.
Type 2 diabetes is caused, not by the absence of insulin, but by insulin's not working properly. It is much more frequent in overweight adults over the age of 45, but can occur at any age and weight. There are often no symptoms.
The National Institutes of Health estimates that more than 7 million adults in the United States have undiagnosed type 2 diabetes.
As obesity becomes more common among children, the number of children with prediabetes and with type 2 diabetes has been rising dramatically in recent years.
Homeopathy has a rich and controversial history. It began in the late 1700's and early 1800's, at a time when medical doctors relied primarily on bloodletting, intestinal purging, induced vomiting, and blistering of the skin to treat their patients' maladies. A brilliant physician named Samuel Hahnemann, M.D. was dissatisfied with the status quo. He was bothered both that current treatments were harsh and dangerous and that they failed to produce good results.
Hahnemann began to recommend exercise, good diet, and fresh air to his patients. He believed that healing came from God and Nature, and that the physician's role was only to gently encourage this natural process.
Over time, he became increasingly disturbed by the lack of experimental basis for popular conventional therapies.
He believed that each medicine should be tested, to see what it really did, before it was used as a treatment.
He set out to prove the effects of the common remedies of his day. The first experiment was with quinine, known to treat malaria and its raging fevers. When he took quinine while well, it produced a fever. This, and subsequent experiments, gave rise to his Law of Similars -- that remedies which produce specific symptoms in well persons are effective in treating ill persons with the same symptoms. This is where the name homeopathy ("like the disease") comes from.
Hahnemann's treatments tended to produce an initial worsening of symptoms, often followed by a cure. To make the process more agreeable, he decided to dilute the substances he was using. The surprising result was that the remedies became even more potent. This led to the second law of homeopathy, the Law of Infinitesimals: the smaller the dose of a medicine, the more effective it is in stimulating the body to heal itself.
Over the last two centuries the respect accorded homeopathy has varied widely. Currently, there is a resurgence of its popularity. I greatly admire the gentleness, the reliance on the body's own healing mechanisms, and the bent toward prevention that are central to homeopathy.
Homeopathy began with a desire to prove the effects of medicines by careful experimentation. Today, the number of well done scientific studies on homeopathic remedies are scarce, especially in children. There are over 100 controlled trials in adults, and somewhere in the range of 15 studies in children. Some homeopathic treatments that have been studied in children include treatments for ADHD, ear infections, influenza, and certain chemotherapy related symptoms. However, most of these gentle treatments are touted based on individual testimonials, in much the same manner as were the barbarous practices of conventional medicine two centuries ago. Many people swear that they work. I hope they are right.
Most of the treatments for poison ivy, oak and sumac are aimed at reducing the itching, until the self-limited rash runs its course, which takes about two weeks. Click here for Dr. Greene’s tips on treating these allergic reactions.
