People with type 2 diabetes have insulin resistance, which means the body cannot use insulin properly to help glucose get into the cells. In people with type 2 diabetes, insulin doesn’t work well in muscle, fat, and other tissues, so your pancreas (the organ that makes insulin) starts to put out a lot more of it to try and compensate. "This results in high insulin levels in the body,” says Fernando Ovalle, MD, director of the multidisciplinary diabetes clinic at the University of Alabama in Birmingham. This insulin level sends signals to the brain that your body is hungry.
Not until I actually got this book into my hands could I see that its subtitle read "A medical approach that can slow, stop, even cure Type 2 Diabetes". If I'd known about the subtitle, I wouldn't have been interested in reading the book, since the "medical approach" bit indicated for me that it consisted of traditional precepts penned by a doctor, and also I am not particularly interested in Type 2 diabetes, only Type 1, which I myself have.
Around 75% of people with diabetes have type 2 diabetes mellitus. This was earlier termed non-insulin dependent diabetes mellitus (NIDDM) or maturity-onset diabetes mellitus. The number of people with type 2 diabetes is rapidly increasing. In type 2 diabetes, not enough insulin is produced or the insulin that is made by the body is insufficient to meet the needs of the body. Obesity or being overweight predisposes to type 2 diabetes.
If you bring your blood sugar into the healthy range (a hemoglobin A1C reading of 7% or lower), you'll reduce your risk of nerve damage by 60%, according to research from the National Institute of Diabetes and Digestive and Kidney Diseases. "Healthy blood sugar levels can slow the process and ease the pain of diabetic neuropathy," says Aaron I. Vinik, MD, PhD, the director of the research and neuroendocrine unit at Eastern Virginia Medical School.
In animals, diabetes is most commonly encountered in dogs and cats. Middle-aged animals are most commonly affected. Female dogs are twice as likely to be affected as males, while according to some sources, male cats are also more prone than females. In both species, all breeds may be affected, but some small dog breeds are particularly likely to develop diabetes, such as Miniature Poodles.
Vanadium is a compound found in tiny amounts in plants and animals. Early studies showed that vanadium normalized blood sugar levels in animals with type 1 and type 2 diabetes. When people with diabetes were given vanadium, they had a modest increase in insulin sensitivity and were able to lower their need for insulin. Researchers want to understand how vanadium works in the body, find potential side effects, and set safe dosages.
Monitoring your caloric intake may be helpful if you’re overweight, but everyone with type 2 diabetes should track how many carbs they’re taking in. That can be tricky because carbs are in many of the common foods you may already eat, but there are both good and bad sources of carbs. Fruits and vegetables, for example, are good sources, while pretzels and cookies are bad sources. (29)
A 2017 article in the journal Diabetes Care explains that the goals for dietary change should be “healthful eating patterns emphasizing a variety of nutrient-dense foods in appropriate portion sizes.” Additional goals include achieving a healthy weight; attaining healthy blood sugar, blood pressure, and lipid levels; and reducing complications. The authors emphasize developing an individualized plan based on “personal and cultural preferences, health literacy and numeracy, access to healthful foods, willingness and ability to make behavioral changes, and barriers to change.”
I bring this up because sleep apnea increases a person’s risk for developing type 2 diabetes. Also, sleep-disordered breathing is also related to proper nutrition throughout life. And perhaps most importantly, the first line of defense in catching sleep-disordered breathing in patients early, are dentists. This is another area where dentists must get involved if we want to tackle the issue of pervasive type 2 diabetes with any success.
Interestingly, research suggests anxiety may be tied to type 2 diabetes risk. According to a September 2016 study published in the journal Psychoneuroendocrinology, which measured levels of blood glucose and IL-6, a protein in the body that stimulates immune response and healing, found that people with with low inhibition — or attention control — were more likely to have type 2 diabetes.
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.
There is no known preventive measure for type 1 diabetes. Type 2 diabetes – which accounts for 85–90% of all cases – can often be prevented or delayed by maintaining a normal body weight, engaging in physical activity, and consuming a healthy diet. Higher levels of physical activity (more than 90 minutes per day) reduce the risk of diabetes by 28%. Dietary changes known to be effective in helping to prevent diabetes include maintaining a diet rich in whole grains and fiber, and choosing good fats, such as the polyunsaturated fats found in nuts, vegetable oils, and fish. Limiting sugary beverages and eating less red meat and other sources of saturated fat can also help prevent diabetes. Tobacco smoking is also associated with an increased risk of diabetes and its complications, so smoking cessation can be an important preventive measure as well.
I am very excited by the closed-loop artificial pancreas trial which is now in its final stages. Professor Roman Hovorka at the University of Cambridge is currently perfecting an algorithm that enables a continuous glucose monitor and an insulin pump to talk to each other, and take over the delivery of insulin throughout the day and night, to keep glucose levels in range.
To treat diabetic retinopathy, a laser is used to destroy and prevent the recurrence of the development of these small aneurysms and brittle blood vessels. Approximately 50% of patients with diabetes will develop some degree of diabetic retinopathy after 10 years of diabetes, and 80% retinopathy after 15 years of the disease. Poor control of blood sugar and blood pressure further aggravates eye disease in diabetes.
How does high blood sugar (hyperglycemia) feel? To maintain the right amount of blood sugar, the body needs insulin, a hormone that delivers this sugar to the cells. When insulin is lacking, blood sugar builds up. We describe symptoms of high blood sugar, including fatigue, weight loss, and frequent urination. Learn who is at risk and when to see a doctor here.
