How Is Diabetes Diagnosed and Treated?

0% played0% buffered

Diabetes has nearly become an epidemic, both in the US and around the world. This metabolic disorder interferes with the way the body processes energy and affects more than 30 million Americans. That’s approximately one person out of every ten.

Type 1 and Type 2:

Do you know the difference between type 1 diabetes (once called juvenile onset diabetes) and type 2 diabetes (once considered solely an adult’s or older person’s condition)? When sugar can’t get into the cells, the tissues react as if they are starving. That may happen even when there is a lot of sugar in the bloodstream. The cells require insulin to chaperone sugar in. If it is absent (type 1) or if they have stopped responding to it (type 2), the consequence is an energy crisis.

How Is Diabetes Diagnosed?

One way doctors diagnose diabetes is through an oral glucose tolerance test. A fasting person drinks a known dose of glucose. Over the next two hours, blood sugar is measured at prescribed intervals. This is an accurate way to evaluate diabetes, but it is time-consuming and cumbersome.

The most common diagnostic test physicians utilize is known as the glycosylated hemoglobin test, abbreviated HbA1c. This is preferable to a single measurement of blood sugar because it gives a snapshot of glucose levels in the blood over the past several weeks. It is far more convenient than the oral glucose tolerance test, though it may not be quite as accurate.

How Diabetes Is Treated:

For people who have diabetes, the HbA1c can offer a helpful measurement of how well they are controlling their blood sugar overall. Doctors have long encouraged patients to get this number as low as possible. However, they are now starting to re-think that advice. First, it may encourage people to obsess about what they eat. More importantly, though, it can expose people with diabetes to episodes of low blood sugar (hypoglycemia). This complication can be especially dangerous for older individuals.

Research such as the ACCORD trials produced startling results: instead of people thriving as the measures of blood sugar control, cholesterol and blood pressure dropped, they did less well. Have these studies changed the way doctors treat diabetes?

Are Older People Being Overtreated for Diabetes?

Aging may reduce physiological resilience. As a consequence, when older people have an episode of lower-than-average blood sugar, they may become dizzy or even fall. In some cases, this could have catastrophic consequences. Moreover, when older people suffer symptoms of hypoglycemia, medical personnel could mistake these for a transient ischemic attack (TIA), a precursor to a stroke. In response, some diabetes experts try just as hard to prevent low blood sugar as high blood sugar in their older patients.

Why Do Some Patients Ration Their Insulin?

Insulin is a life-saving medication for anyone with type 1 diabetes and for some of those with type 2 diabetes. It’s not “nice to have” but rather “must have.” Yet the price of insulin has been skyrocketing. Many people with diabetes find they cannot afford the insulin they must have and cut back on how much they use, putting their health and even their lives at risk. Our guest, Dr. Kasia Lipska, testified to Congress about these risks.

I am 80 and have diabetes 2 and neuropathy. I take daily injections of insulin. 250 mm of metformin daily. Exercise daily. Diet is plant-based. I Keep a positive attitude. Keep social. Either move it or loose it. Blood sugar is 95 to 110.

Neuropathy is a different game. Pain, burning, and numbness. There is one supplement I have taken and am feeling less pain and numbness after six weeks. Along with diet, swimming, exercise and all of the above, I feel better.

I have recently been diagnosed with diabetes at age 72. I have been treated with metformin, invokana, jardiance, and farxiga….all of which seem to make me feel terrible due to the side effects. I am probably 20 lbs overweight and am not sure where to turn next. I feel that I am totally at the mercy of big pharma and locked into “traditional” methods of treatment. The doctor that I go to seems to be totally educated to use drugs for everything rather than recommending exercise, diet change, etc. I live in a rather remote area where endocrinologists are far away and it is difficult for me to get to them. What are my options?

Seems to me that people just don’t suddenly become diabetic, especially with type 2. What is the root cause? I suspect years and years (decades) of overeating which has caused insulin to spike to the point where it can no longer be taken in by the liver and therefore gets turned into fats that are then stored in the body. So now the body has a ready supply of energy (fats convertible into sugars) and still a person is trying to add more energy by eating tons of food. All foods/drinks with more than a few calories will affect insulin and blood sugar levels to various degrees.

Some doctors are having great success by using various forms of fasting to get diabetes under control and rid the body of excess fats (weight loss) and even fully reversing type 2 diabetes in weeks or months. Drugs are not used, and often a person can reduce dosages or get off their drugs all together. Of course, most main-stream doctors are fully against this. By the way, I am enjoying your book “Top Screwups Doctors Make,” and it has further supported my idea of seldom having to rely on the main-street medical system if it can be avoided.
