Mechanism's For Controlling Blood Sugar Levels:
The blood glucose level is the amount of sugar or glucose in the blood that is also referred to as plasma glucose level and expressed as millimoles per litre. While blood glucose levels are measured in order to diagnose and monitor diabetes, it's also important to monitor these levels in certain situations, especially with increasing age and during pancreatitis and pregnancy. Under normal circumstances, blood sugar levels usually stay within a daily narrow limit of between 4 and 8 millimoles per litre. In addition, the levels of blood glucose in the body are usually higher after meals and lowest in the morning. Nonetheless, the body has certain mechanisms that help in controlling blood glucose levels under normal and stress conditions.
The body basically maintains a minimum level of glucose in the blood and also limits surges of glucose after a meal by about 70 mg/dl and not to exceed 140 mg/dl respectively. Generally, the level of glucose in the blood is regulated by hormones secreted through the islets of Langerhans in the pancreas. Islets play a crucial role in this process since they consist of alpha cells and beta cells that produce glucagon and insulin respectively (Zamora, 2012).
When the blood glucose level increases after a meal, the beta cells discharge insulin to enable the conversion of glucose to glycogen and fat. As a result, the blood glucose level returns to normal after the glucose has either been burned or stored as fat or glycogen. However, when the blood glucose level...
role of hormones in the control of body fuel/energy mechanism has been appreciated for close to a century (Dzamko & Steinberg,2009). This concept was identified by the groundbreaking findings by the scientists, Banting et al. (1922) that the hormone, insulin could effectively restore euglycaemia. This paper seeks to give an in depth understanding of metabolism by definition and gives the various component of metabolism and finally the hormonal influence
Public health screening activities in programs are also essential in ensuring this level of prevention is ensured. A good example is organized screening programs targeted at the community. The third level of prevention, tertiary prevention, involves bother rehabilitative and therapeutic measures once the person already has the symptoms and signs of the disease. Tertiary prevention has several goals, which include preventing damage and pain that may arise from the disease,
Diabetes Mellitus Type II Diabetes is described as a condition that results from a chronic problem of hyperglycaemia that is brought about by insulin inaction in the body system. Diabetes type II is a condition that fronts the case for a range of diabetic problems characterised by some pathophysiological symptoms, including increased insulin resistance and impaired insulin secretion. The problems observed in the cell function and the deteriorating pancreatic conditions
The structure of Byetta is similar to that of GLP-1 and performs the same functions. Both promote decreased appetite (Wilson). Dr. Wysham was an observer at a study conducted on 20 Rockwood diabetic patients who were taking conventional diabetic medication for their uncontrolled blood sugar (Wilson 2005). She was not informed about their glucose levels for several months after the tests began. About two-thirds of the respondents were given different
Endocrinology AMAZING HORMONES Counterbalance of Sugar and Fat Content between Insulin and Glucagon Physical survival depends on the sustained availability and use of energy in the form of adenosine triphosphate or ATP from sufficient levels of a substance, called glucose (Bowen, 2001). The use of energy depends on the varying levels of activity. Hence, the amount of glucose needed for activity likewise varies each day. Too much or too little glucose is damaging
Biological Mechanisms of Hunger What Causes Hunger: The Biological Mechanisms of Hunger The biological mechanisms that trigger hunger are rather complex. In that regard, several theories have been proposed in an attempt to explain hunger and the biological mechanisms that control it. It is therefore important to note that the feeling of hunger has no single source. Indeed, as Pastorino and Doyle-Portillo (2012) point out; although the stomach plays a role in
