Negative feedback loop insulin10/11/2023 ![]() See Table 9.1 for a list of hormones associated with each of these glands and their effects. This module will focus on medications that affect three major endocrine glands and their hormones: the adrenal glands, the pancreas, and the thyroid. Figure 9.1 Overview of the Endocrine System For example, the pancreas contains cells that function in digestion, as well as cells that secrete the hormones insulin and glucagon, which regulate blood glucose levels. Some of these glands have both endocrine and nonendocrine functions. See Figure 9.1 for an illustration of the endocrine system. Some of the glands in the endocrine system include the pituitary, thyroid, parathyroid, adrenal, and pineal glands. Hormones are transported primarily via the bloodstream throughout the body, where they bind to receptors on target cells, inducing a characteristic response. These hormone signals are sent by the endocrine organs. Whereas the nervous system uses neurotransmitters to communicate, the endocrine system uses hormones for chemical signaling. This long-distance intercellular communication, coordination, and control are critical for homeostasis, and it is the fundamental function of the endocrine system. Similarly, certain cells send chemical signals to other cells in the body that influence their behavior. You may never have thought of it this way, but when you send a text message to two friends to meet you at a restaurant at six, you’re sending digital signals that you hope will affect their behavior-even though they are some distance away. This will not only lower your blood sugar and help your insulin work better it will also lower your blood pressure and improve your heart health.\) You should try to exercise five days a week for at least 30 minutes. It is especially important to eliminate excess weight around your waist. Losing as little as seven percent of your weight may be all that is needed to stop diabetes in its tracks. The good news is that changing your lifestyle may stop the progression of type 2 diabetes or even reverse it. In addition, controlling diabetes usually requires frequent blood glucose testing, watching what and when you eat and taking medications or even insulin injections. The risk of death in adults with diabetes is 50 percent greater than it is in adults without diabetes, and diabetes is the seventh leading cause of death in adults. Diabetes can lead to heart attacks, strokes, blindness, kidney failure, and loss of toes or feet. Once the diagnosis of diabetes sinks in, you may be devastated by the news. You are not alone, because as many as one in four diabetics does not know they have the disease. If your blood glucose level indicates that you have diabetes, it may come as a shock to you because you may not have any symptoms of the disease. You are likely to have your blood glucose level tested during a routine medical exam. Today, about 30 million Americans have type 2 diabetes, and another 90 million have pre-diabetes. Even children are now being diagnosed with type 2 diabetes. ![]() However, because of the dramatic increase in recent decades in obesity in younger people, the age at which type 2 diabetes is diagnosed has fallen. Type 2 diabetes typically starts after the age of 40. ![]() Of the two types of diabetes, type 2 diabetes is the most common, accounting for about 90 percent of all cases of diabetes in the United States. A level between 100 and 125 places you in the pre-diabetes category, and a level higher than 125 results in a diagnosis of diabetes. A fasting level of blood glucose below 100 is normal. \): Maintaining homeostasis through feedback requires a stimulus, sensor, control center, and effectorĭiabetes is diagnosed in people who have abnormally high levels of blood glucose after fasting for at least 12 hours.
