Diarrhea and constipation may also stem from diabetes-related gut movement issues. And the conditions may be related. “Diarrhea doesn’t mean fast motion; constipation doesn’t mean slow movement,” says Mashimo, happy to clear up a common misconception. “They can be two sides of the same coin.” Constipation, he says, is caused by slow movement of the bowels, which can cause a buildup of harmful bacteria in the colon that, in turn, triggers diarrhea.
Currently, no fully artificial pancreas system has been approved by the FDA for use in the U.S. The most advanced product on the market in the USA is currently Medtronic’s MiniMed system which can automatically suspend insulin delivery when it detects low blood sugars. The next generation of their system will anticipate low blood sugars and stop insulin delivery in advance.
Gestational diabetes mellitus (GDM) resembles type 2 DM in several respects, involving a combination of relatively inadequate insulin secretion and responsiveness. It occurs in about 2–10% of all pregnancies and may improve or disappear after delivery. However, after pregnancy approximately 5–10% of women with GDM are found to have DM, most commonly type 2. GDM is fully treatable, but requires careful medical supervision throughout the pregnancy. Management may include dietary changes, blood glucose monitoring, and in some cases, insulin may be required.
The classic oral glucose tolerance test measures blood glucose levels five times over a period of three hours. Some physicians simply get a baseline blood sample followed by a sample two hours after drinking the glucose solution. In a person without diabetes, the glucose levels rise and then fall quickly. In someone with diabetes, glucose levels rise higher than normal and fail to come back down as fast.
People with diabetes are unable to control the level of sugar in their blood, usually due to a breakdown in how their bodies use the hormone insulin. It’s not completely clear how obesity can contribute to diabetes, but it is known that excess weight is associated with chronic inflammation and a dysfunctional metabolism. And these factors in turn make it easier for someone to stop responding to the presence of insulin as easily as they once did. So by using surgery to help very obese people with diabetes lose weight, the logic goes, you can indirectly treat or prevent the condition. But doctors such as David Cummings, a senior investigator at the University of Washington’s Diabetes & Obesity Center of Excellence, are pushing back against this way of thinking.
Diabetes can also result from other hormonal disturbances, such as excessive growth hormone production (acromegaly) and Cushing's syndrome. In acromegaly, a pituitary gland tumor at the base of the brain causes excessive production of growth hormone, leading to hyperglycemia. In Cushing's syndrome, the adrenal glands produce an excess of cortisol, which promotes blood sugar elevation.
The United Kingdom Prospective Diabetes Study (UKPDS) was a clinical study conducted by Z that was published in The Lancet in 1998. Around 3,800 people with type 2 diabetes were followed for an average of ten years, and were treated with tight glucose control or the standard of care, and again the treatment arm had far better outcomes. This confirmed the importance of tight glucose control, as well as blood pressure control, for people with this condition.
Wellness was so unfamiliar at the time, Travis recalls, that he constantly had to spell the word when using it over the phone. It soon got national attention when a young doctoral student named Donald B. Ardell profiled Travis’s center in the April 1976 issue of Prevention magazine. In a sidebar, Prevention’s editor, Robert Rodale, welcomed the “exciting field of wellness enhancement,” promising that the magazine would “examine all aspects of wellness promotion.” Even greater exposure came with Rather’s “60 Minutes” piece, which focused on Travis and the Mill Valley center.
Glucose is a simple sugar found in food. Glucose is an essential nutrient that provides energy for the proper functioning of the body cells. Carbohydrates are broken down in the small intestine and the glucose in digested food is then absorbed by the intestinal cells into the bloodstream, and is carried by the bloodstream to all the cells in the body where it is utilized. However, glucose cannot enter the cells alone and needs insulin to aid in its transport into the cells. Without insulin, the cells become starved of glucose energy despite the presence of abundant glucose in the bloodstream. In certain types of diabetes, the cells' inability to utilize glucose gives rise to the ironic situation of "starvation in the midst of plenty". The abundant, unutilized glucose is wastefully excreted in the urine.
The word mellitus (/məˈlaɪtəs/ or /ˈmɛlɪtəs/) comes from the classical Latin word mellītus, meaning "mellite" (i.e. sweetened with honey; honey-sweet). The Latin word comes from mell-, which comes from mel, meaning "honey"; sweetness; pleasant thing, and the suffix -ītus, whose meaning is the same as that of the English suffix "-ite". It was Thomas Willis who in 1675 added "mellitus" to the word "diabetes" as a designation for the disease, when he noticed the urine of a diabetic had a sweet taste (glycosuria). This sweet taste had been noticed in urine by the ancient Greeks, Chinese, Egyptians, Indians, and Persians.
