The Effect Of Body Composition, Size And Age On The Regulation Of Glucose

Plasma insulin/glucagon concentration differed significantly. Insulin levels were at their highest during 1 hour post meal time exceeding 180

The students who continued fasting after the 12hr fasting period has almost equal amounts of blood glucose concentrations (BGC), during the 90mins period, with averages ranging from 4.3- 4.7 mmol/l. This was the negative control. The average BGC of students who ate 100g white bread elevated after 60 minutes. Students who ingested 100g of lean chicken after fasting, had a lower BGC than the white bread.

Diabetes is a long-term metabolic condition characterized by high blood sugar levels. There are three major categories of the disease, type 1 diabetes occurs when the body produces minimal or no insulin, type 2 diabetes is when the body produces either little insulin or the cells are unable to respond to insulin, gestational diabetes mainly occurs during pregnancy. Non-Insulin Dependent Diabetes Mellitus, which is, type 2 diabetes is the most prevalent. The major complication that is caused by Type 2 diabetes is unremitting hyperglycemia, which leads to numerous changes in the body. There are several alterations in cellular, cardiovascular, and nervous functioning, which contribute to complications such as neuropathies and heart

The body regulates the blood glucose levels by producing insulin. Insulin is a chemical messenger essential for the entry of glucose into a cell. When the pancreas fails to produce insulin that is sufficient to use, the level of glucose in the blood will remain high. If to much insulin is produced, or given through medication, the level of glucose in the blood will remain low. In type 2 diabetes the cells become resistant to insulin and ignore its message to be absorbed into the cells, this is known as insulin resistance. Insulin deficit results in decreased transportation of glucose from cells in the body, hyperglycemia then arises causing to much glucose to be present in the bloodstream (Gould and Dyer, 2011: 550). The pancreas is located

Energy is essential for survival, and the human body is remarkably efficient at utilizing different energy sources. The body can obtain energy from glucose when consuming a normal carbohydrate diet, or from ketone bodies when consuming a ketogenic diet. This is an alternative source of energy that the body will use when 5% (or less) of total kcal come from carbohydrates. Metabolic processes differ depending on the energy source. One application of understanding the metabolic processes is the imprevment of glycemic control and stop of medications use under a low carbohydrate ketogenic diet. with type II diabetes can

Diabetes mellitus, commonly known as diabetes, is a metabolic disorder characterized by chronic high blood sugar levels. It is caused by an absolute or functional deficiency of circulating insulin, resulting in an inability to transfer glucose from the bloodstream into tissues where it is needed as fuel (Ahmed, Laing and Yates 2011). The disruption in the metabolism of carbohydrates, fats and proteins interferes with the secretion or action of insulin, which plays a vital role in the metabolism and utilization of energy from the nutrients especially carbohydrates. Insulin is produced in the pancreas and secreted in the gastrointestinal tract in the response to high blood sugar levels after ingestion of a substance (REFERENCE).

Diabetes mellitus (or diabetes) is a threatening disease which occurs as a result of loss of uptake of glucose by cell thus increasing its concentration in the blood(Walker and Colledge 2013). Glucose, normally referred to as blood sugar is mainly present in blood and acts to provide energy to the body. It can be thought of a syndrome of hyperglycemic condition where disorders in metabolism occur(Tierney, Saint et al. 2002). It can be termed as metabolic sickness portrayed by hyperglycemia which result due to deformities in insulin discharge, its activity or both of these(Alberti and Zimmet 1998, American Diabetes 2010). The chronic state of disease is that in which hyperglycemia can lead to disorders affecting organs such as kidneys, heart ,eyes and blood vessels etc.(American Diabetes 2010).Diabetes occurs usually when the release of

This is a critique of the quantitative research article titled Influence of Obesity and Type 2 Diabetes on Gluconeogenesis and Glucose Output in Humans studied by Amelia Gastaldelli, Simona Baldi, Maura Pettiti, Elana Tischi, Stefania Camastra, Andrea Natali, Bernard R. Landau and Ele Ferrannini. This article was published in the journal Diabetes in 2000 volume 49 issue 8 pages 1367-1373. Purpose, PICO and Level of

According to the Center for Disease Control, diabetes is the condition in which the body does not properly process for use as energy (Center for Disease Control, n.d). The body supplies its energy by turning in most of the food an individual takes in by turning it into glucose, which is sugar for the body to use as energy (Center for Disease Control, n.d). Diabetes develops because the body does not make enough insulin or is unable to use the insulin it produces effectively. As a result, the glucose or sugar builds up in the individuals’ blood. If severe, diabetes has the potential to cause serious health complications which include heart diseases, failure of the kidneys, blindness and lower-extremity amputations (Center for Disease Control, n.d). In fact, according to the Center for Disease Control, diabetes is the 7th leading cause of death in the United States (Center for Disease Control, n.d). Moreover, African Americans are 1.7 times as likely to

Adjustment for age, insulin sensitively among people who were known as vigorous PA five or more times a week was significantly higher than people who were never vigorous in PA

Homeostasis is the maintenance of near constant conditions/ state of the internal environment of an organism, this is important for the organism as it needs to maintain a near constant internal environment, it does this by allowing the body cells to function at optimal levels so internal and external influences don’t affect the state and conditions of the organism. An example of a homeostatic system is blood glucose regulation. It is the process that is maintained by the body for the levels of blood sugar; glucose, Glucose regulation is a process in the body that keeps it in homeostasis; insulin and glucagon are the main hormones involved in the process. Blood glucose is produced from food we eat, especially carbohydrates, fats and proteins, this is the main source of energy for the human body. Blood glucose is transported to the cells by the circulation and into cells by glucose transporters; some are regulated by insulin. Insulin is one of the hormones produced by the pancreas in which regulates the glucose levels in the blood around the body. Glucose is needed for respiration and the concentration levels of glucose in the blood is important to be kept and maintained at a near constant level (70 to 115mg, in a normal adult). Hyperglycemia means high blood glucose levels, this can caused by several factors such as poor food/ diet and physical activity choices and even illness. The body needs glucose to properly function due to being

The prevalence of diabetes increases with age. Approximately 21% of older adults aged 60 years in the United States have diabetes. According to CDC, from 1980 through 2011, the rate of diagnosed diabetes increased 167% for people aged 0-44 years, 118% for those aged 45-64 years, 140% (9.1% to 21.8%) for those aged 65-74 years, and 125% (8.9% to 20.0%) for those aged 75 years and older. In general, throughout the time period, the rate of diagnosed diabetes increased among people of all age groups. In 2011, the prevalence of diabetes among people aged 65-74 (21.8%) was more than 13 times that of people younger than 45 years of age (1.6%).

Homeostasis is what physiological systems in our bodies do in order to maintain a stable internal environment. Stability is held together by the coordinated responses of the components involved to any stress or unfamiliar situation that the human body is put under that could disrupt its normal functioning conditions. Homeostasis must be maintained constantly in order for our bodies to be able to function properly and not under stress which could have major effects later on in life.

The control of glucose levels in the blood is an example of homeostasis. Homeostasis is the body maintaining a stable internal state despite changes in the external environment. This homeostasis is achieved through negative feedback. Negative feedback is when a deviation of normal levels is brought back to the normal level by a corrective response. The larger the deviation from the normal, the greater the corrective response will be. The level of glucose in the blood achieves homeostasis by its removal from the blood being balanced with its entry into the blood.

Although the investigation was able to provide more knowledge and understanding regarding the relationships between energy, activity levels and carbohydrate intake in order to contribute towards a solution to the problem of obesity, there were many limitations to this experiment that needed to be considered. For the personal data, the dietary observations collected over the two experimental days were not substantial to represent their lifestyle as a whole. Studies led by Burke et al., (2001) demonstrated that individuals can make inaccurate reports in various ways such as altering their dietary intake during period of recording, omitting or underestimating their intake and quantification errors of their consumption. As the group data was a collation of individual’s two-day dietary records, variability and inaccuracy increased considering the wide range of influences each individual may have been subjected to. There were 359 females and 195 males involved in the
