The Endocrine System:
Diabetes, Obesity

Late in the year 2001, the U.S. Centers for Disease Control and Prevention (CDC) released a report that should have been front-page news. It was an alarming account of the dramatic and parallel rise in the incidence of both obesity and diabetes. Calling these two health concerns “twin epidemics,” CDC Director Dr. Jeffrey P. Koplan warned, “If we continue on this course for the next decade, the public health implications in terms of both disease and health care costs are staggering.”1 Dr. Koplan called on the health-care industry, along with schools and communities, to intensify efforts to prevent and treat these epidemics. Maybe the most striking aspect of the report was the admission that both diabetes and obesity are largely preventable through proper diet and exercise, yet over 60 percent of Americans are overweight and about fifteen million of us have diabetes. This means that more than half of the population is affected, and many people will die prematurely owing to their own unhealthy lifestyles.

Diabetes is a disease of the endocrine system, the system in our bodies responsible for producing and distributing hormones. It is caused by a lack of insulin, a hormone produced by the pancreas, or the ineffective action of insulin in the body. In type 1 diabetes, the pancreas stops producing insulin and the person with this condition must take insulin daily to stay alive. In type 2 diabetes, the pancreas is still producing insulin but the body is resistant to the insulin and does not use it effectively. In both types of diabetes, the lack of insulin activity results in high blood sugars and all the complications of diabetes.

Persons with type 1 diabetes always need to take insulin. In addition, proper diet, exercise, and weight control are an important part of controlling the diabetes and preventing complications. The major complications of diabetes are eye disease, foot problems, heart disease, and kidney problems.

Type 2 diabetes can often be treated by proper diet, exercise, and weight control alone. When lifestyle changes don't work well enough to bring the blood sugar under control, oral medications are prescribed. Some persons with type 2 diabetes will need to take insulin when the oral medications are not working adequately. One of the biggest risk factors for type 2 diabetes is obesity, which is caused by a complex relationship of genetics and behavior. Obesity can be partially caused by endocrine system problems, such as incorrect levels of thyroid hormones, insulin, or sex hormones. For this reason, we are covering obesity here along with the endocrine system. Keep in mind that most people who are overweight do not have a problem with their endocrine system; but if their weight problem continues, it's possible they eventually will have an endocrine problem—diabetes.

PHYSIOLOGY 101

The Endocrine System

The endocrine system is made up of glands throughout the body that secrete hormones—chemical messengers that regulate bodily processes such as growth, metabolism, and sexual development. The endocrine system keeps our body in balance through the function of hormones. The master gland is the hypothalamus, a tiny cluster of brain cells that receives messages from the body and transmits signals to the pituitary gland. The pituitary gland makes hormones in answer to the body's needs. These pituitary hormones signal other endocrine organs, such as the adrenal gland, thyroid gland, ovaries, and testes, to produce the hormones needed for good health. The ovaries (in females) and testes (in males) receive the messages from the pituitary and in turn produce the sex hormones—estrogen and progesterone in women, testosterone in men.

The pancreas is another gland that affects digestion. It lies behind the stomach. This gland secretes digestive juices that break down fats, carbohydrates, proteins, and acids. Within the pancreas are specialized cells that secrete hormones— glucagon and insulin—that together regulate the level of glucose in the blood. If the pancreas fails to produce insulin or secretes it in low quantities, the result is diabetes.

ENDOCRINE SYSTEM AILMENTS

Diabetes

In diabetes, your body does not properly produce or use insulin, a hormone needed to convert sugar, starches, and other food into energy needed for daily life. Type 1, in which patients require daily insulin injections to stay alive, makes up only 5 to 10 percent of diabetes cases. Type 2 diabetes is much more common. It is type 2 diabetes that the CDC reports is nearing epidemic proportions, and doctors believe it is due to the rise in obesity, sedentary lifestyles, and unhealthy diets.2

Controlling your diet is crucial when you have diabetes. Lowering fats, sugar, and alcohol and eating healthy amounts of whole grains, vegetables, and protein are the general guidelines. The book Diabetes Meal Planning Made Easy: How to Put the Food Pyramid to Work for Your Busy Lifestyle,sanctioned by the American Diabetes Association, shows you how to create a nutritional plan that works (see Resource Guide).

Exercise is one of the best ways to improve your health if you are diabetic, helping you lose weight and normalize blood sugar. However, you need to be careful about your blood sugar during exercise. It helps to have eaten relatively recently before exercising and to test your blood before and after exercise, especially if you take insulin. Most important, exercise should be done regularly, several days a week.

If you have obesity and diabetes simultaneously, healthy weight loss through diet and exercise can cause type 2 diabetes to disappear entirely. If you are steadily losing weight and staying healthy, be sure to get tested regularly by your doctor. Your diabetic medications will probably be lowered and may eventually be completely discontinued. If you have type 2 diabetes, be sure to read Yoga for Type 2 Diabetes and Obesity.

Obesity

Being overweight is a disheartening predicament that over half of Americans find themselves in. Doctors now determine whether and how much a person is overweight by figuring his or her body mass index (BMI). This measure is the ratio of your height to your weight (see Appendix C). Percentage of body fat is another reliable indicator of whether or not you are at a healthy weight, and some experts believe it may be a more accurate gauge than BMI.3 One advantage of BMI is that it's easy to figure on your own with the help of a calculator, whereas you may not be able to get an accurate body fat percentage without seeking professional help. The bottom line is that weight, body fat, and BMI are all good tools for helping you determine where you lie on the healthy-weight spectrum. You should use them to help in your self-evaluation, but also consider how you feel, how many illnesses you tend to get, your energy levels, and how you look in the mirror.

Obesity has immense health risks. Heart disease, high blood pressure, stroke, and diabetes vastly increase with obesity, and the musculoskeletal system can be affected, most commonly by lower back pain, knee pain, arthritis, and carpal tunnel syndrome.

The best way to approach obesity is through a threefold plan of attack: Get your diet under control, find the amount and types of exercise that work for you, and find strategies that can help you maintain your resolve. These may include stress management, nutritional counseling, keeping a journal of your eating and exercise patterns, psychotherapy, accountability to another person, and mind–body practices that can increase your self-awareness and sense of personal power. See the Resource Guide for some diet book recommendations. If you are seriously overweight, be sure to read Yoga for Type 2 Diabetes and Obesity.

The Yoga Advantage for Endocrine Ailments

The key to controlling body weight and diabetes is lifestyle. We all need to develop the discipline to exercise regularly and choose healthy foods. One of the greatest benefits of Yoga is that it helps you develop self-control. As you practice Yoga, you become more skilled at concentrating, and you learn to manage your thought processes. This can increase your willpower to make changes, even if they are difficult or unpleasant, such as cutting back on sweets.

People are often waylaid from their best intentions for diet and exercise by stress. Once you have a regular and reliable means of controlling stress, you can count on more success with your self-discipline. As we've discussed throughout this book, Yoga is one of the most effective stress busters available. Yoga is also known for increasing general feelings of well-being. When you're happy and content, it is easier to make choices that contribute to your health rather than your momentary pleasure.

Controlling stress can also have very concrete benefits in controlling diabetes. A landmark study of people with diabetes released in 2002 showed that stress-management techniques, including relaxation and breathing exercises, can significantly reduce the average glucose level, the important factor in diabetes. The effect was so great that the researchers compared it to the change they would expect to see from some diabetes-control drugs, and they concluded that “Managing stress can significantly improve a patient's control of their diabetes.”4

Yoga is an ideal form of exercise if you are overweight. It is gentle and doesn't push you beyond your limits. It can be successfully practiced even by overweight individuals who may have given up on exercise because it was too difficult. Yoga does not strain the heart and when carefully practiced, has a very low risk of injury.

For people with diabetes, Yoga is a healthy form of exercise because it does not burn calories and bring down blood sugars as rapidly as more vigorous exercise such as jogging or aerobics. Because Yoga is usually done indoors in places where there is access to food or drinks, it is more likely that you will have some food available for treatment if your blood sugar should drop drastically.

Lydia was 46 and had been healthy all her life, but at age 42 she went through a difficult divorce and a long bout of depression. She gave up exercise and gradually her diet deteriorated, leading her to put on weight. Eventually her doctor diagnosed type 2 diabetes and obesity, put her on medication, and advised her to improve her diet. Her symptoms improved but she still suffered from fatigue, depression, and irritability, so Lydia's physician referred her to me. I worked closely with Lydia on her diet, increasing whole grains, beans, and vegetables and reducing fats, sweets, and alcohol. For exercise, she began walking regularly and practicing a daily Yoga routine similar to the one in this chapter. Her symptoms improved after only two weeks, and after three months she had lost sixteen pounds and her glucose levels had significantly decreased, so her doctor cut her medication dose in half. Lydia may continue to need medication for her diabetes, but she is much healthier and reports feeling great.

Being overweight can take a major toll on our self-esteem, reminding us of our perceived failures and lack of ability to change. One of the greatest advantages of Yoga is that it helps you see yourself in a different way. You can leave behind your disappointing image of yourself to discover your inner strength and the ability to make real changes in your life. Yoga is a gentle way to bring a balanced attitude to all aspects of life. If you commit to a regular practice and embrace all the principles of Yoga as explained in this book, you can achieve permanent weight loss, decrease or eliminate symptoms of diabetes, and rebuild your self-esteem to embrace life with confidence.

The Yoga Prescription for Endocrine Ailments

For Diabetes

YOGA FOR ENDOCRINE AILMENTS

Yoga for Type 2 Diabetes and Obesity

This routine is similar to the one I created for Lydia. It takes about twenty minutes, and should be practiced using Belly Breathing or Focused Breathing Part Two. Inhale and exhale through the nose slowly with a slight pause after both the inhale and the exhale. Ideally practice twice a day until you are within your healthy weight range or your diabetes is under control. Then you can practice once a day.

Seated Posture

This basic posture will used throughout the routine.

  1. Sit comfortably in an armless chair, bringing your body slightly away from the back rest.

  2. Let your arms hang down by your sides. Place your feet evenly on the floor at hip width. If your feet do not touch the floor, place a folded blanket or a phone book under them. Your thighs should be parallel to the floor with your knees and hips bent at approximately a 90 degree angle.

  3. Place your hands on your thighs with your fingers toward your knees. Bring your back up nice and tall, and gently pull your head back until your ears, shoulders, and hip sockets are in alignment. Do not force anything beyond your comfort level.
