The insulin secretory capacity of the β-cell is augmented in an attempt to overcome this disturbance. Thus, an individual with impaired glucose tolerance or early diabetes mellitus (FBS-120 mg/dl) can secrete up to twice as much insulin as a normal person (FBS- 80 mg/dl) would. When, however, the fasting glucose level increases further, the β-cell can no longer maintain increased secretion of insulin. Thus further increase in the plasma glucose concentration is associated with a progressive decline in insulin secretion. Hence a diabetic person (FBS - 150mg/dl or more) will secrete an amount of insulin similar to that in a nondiabetic individual (18).
The risk of diabetes type two is greatly increased by lifestyle factors such as; overweight, lack of exercise, poor diet and high blood pressure. http://www.diabetesaustralia.com.au/Understanding-Diabetes/What-is-Diabetes/Type-2-Diabetes/#Managing Type 2 Diabetes. 2. a) What are the three main aims when treating Tom (a newly diagnosed diabetic). • Ensure Tom maintains a healthy low carbs, sugar free diet. • Encourage Tom to exercise more frequently.
2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries. The fatty deposits, called atheroma, are made up of cholesterol and other waste substances. The build-up of atheroma on the walls of the coronary arteries makes the arteries narrower and restricts the flow of blood to the heart. Cholesterol is a fat made by the liver from the saturated fat that we eat. Cholesterol is essential for healthy cells, but if there is too much in the blood it can lead to CAD.
(Brown and Edwards (2012) p. 1360. Insulin resistance caused by the receptor sites being unresponsive to the insulin especially in the muscle cells as well as the fat and liver cells. As the receptor sites for the insulin are not working the pancreas produces more insulin (homeostatic balance) to try and reduce the high blood glucose levels. These Beta cells become exhausted, and stop working effectively. Because the glucose cannot enter the target cells the liver produces excessive glucose to try and compensate resulting in high fasting blood glucose levels.
How does type 2 diabetes occur? Type 2 diabetes occurs when insulin is not used effectively by the body resulting in: Insulin resistance and Hyperglycemia In advanced stages, type 2 diabetes mellitus may lead to damage to insulin producing cells leading to insulin deficiency.Find tips to lead a healthy lifestyle, by eating well, keeping active, maintaining a healthy weight and monitoring your health. Sometimes diet and exercise are not enough to control Type 2 diabetes and you may need diabetes
What is hyperglycemia? Hyperglycemia is the technical term for high blood glucose (blood sugar). High blood glucose happens when the body has too little insulin or when the body can't use insulin properly. What Cause Hyperglycemia? A number of things can cause hyperglycemia: If you have type 1, you may not have given yourself enough insulin.
This is called insulin resistance. According to Wong Lai Teng, “Insulin resistance is caused by defective insulin receptors on the target cells.” She goes on to state, “Insulin resistance occurs in association with obesity and pregnancy. In normal individuals who are obese or become pregnant, the B cells secrete increased amounts of insulin to compensate. Patients who have genetic susceptibility to diabetes cannot compensate because of their inherent defect in insulin secretion.” In both types 1 and 2 diabetes will show signs and symptoms, although, in type 2 diabetes, they may not be apparent for some
Insulin is a necessity for the body to have in order to change the sugar that you take into energy. Without insulin the sugar will remain unconverted and overload in the body causing extreme health issues and even death. This type of diabetes comes from the simple inability for your pancreas to do the job it was created to do, which is to create this hormone that is desperately needed in our everyday bodily functions. This type of diabetes can be treated by insulin being injected into our systems on a daily basis which does the same function as the not working pancreas. Type two diabetes, is a condition which is more common in the world today and is also known as hyperglycemia.
Ten Reasons to Avoid Soft Drink Consumption: A single can of soda contains the equivalent of 10 teaspoons of sugar. This amount of sugar, especially in liquid form, skyrockets the blood sugar and causes an insulin reaction in the body. Over time, this can lead to diabetes or insulin resistance, not to mention weight gain and other health problems. Soft drink companies are the largest user of sugar in the country. Soda contains phosphoric acid, which interferes with the body’s ability to absorb calcium and can lead to osteoporosis, cavities and bone softening.
The body’s digestive system can’t tell the difference, so it quickly absorbs all the sugars into the bloodstream as glucose. When you eat sugar, your blood glucose level rises. This stimulates the release of insulin, which signals your body to store fat. The more sugar you ingest at one time, the greater the amount of insulin released and the longer your body stays in fat-storage mode. When the body receives an appropriate amount of sugar, in more complex forms, throughout the day, it can absorb and process the sugar as energy over the course of the day.
