What is Diabetes?
Diabetes type 2 is a condition in which blood sugar levels are too high. After eating foods that contain carbohydrates, chemicals in the small intestine break down the carbohydrates into simple sugar molecules called glucose. The cell lining of the small intestine absorbs the glucose, which then passes into the bloodstream. When the blood reaches the pancreas, beta cells in the pancreas detect the rising glucose levels. To reduce the glucose level, beta cells release insulin into the bloodstream. As the blood circulates through the body, the insulin and glucose exit the bloodstream into tissue to reach the body’s cells. Most cells of the body have certain receptors on their surface that bind to the circulating insulin. Insulin acts like a key in a lock to open up the cell so that the circulating glucose can get inside the cell. The cell can use the glucose to produce the energy it needs to function properly. If a person has insulin resistance, insulin cannot unlock the cells to let glucose in because the locks, called receptors, are abnormal and/or missing. As a result, glucose is locked out of the cells. The amount of glucose builds up in the bloodstream in a condition called hyperglycemia. To compensate for hyperglycemia, the pancreas produces more and more insulin. Overworked beta cells try to keep with the demand, but gradually lose their ability to produce enough insulin.
What are the causes of Type 2 Diabetes?

Diabetes refers to a set of several different diseases. It is a serious health problem throughout the world and fourth leading cause of death by disease in the country. All types of diabetes result in too much sugar, or glucos in the blood. To understand why this happens it would helpful if we understand how the body usually works. When we eat, our body breaks down the food into simpler forms such as glucose. The glucose goes into the bloodstream, where it then travels to all the cells in your body. The cells use the glucose for energy. Insulin, a hormone made by the pancreas, helps move the glucose from bloodstream to the cells. The pathophysiology of diabetes mellitus further explains the concept on how this disease works. Pancreas
What is Type 2 Diabetes? When you blood sugar, also known as glucose, is too high, this is known as Diabetes. Glucose is your main source of energy for your body. Glucose is found in food you eat and is also produced in your liver and muscles. You blood stream carries glucose all throughout your body to be used as energy.
Type 2 Diabetes is a disease that is found in a variety of age groups around the world. This disease is growing at a rapid rate and it is impacting the health of this generation and future generations to come. Diabetes is a disease that impairs the body’s ability to produce or respond to the insulin hormone produced by the pancreas. The insulin allows for the glucose to be effectively used as energy throughout the body. Diabetes causes carbohydrates to be abnormally digested, which can raise blood glucose levels. This means that the glucose is not being taken up by the cells that need it. The cells cannot take up the excess glucose that has accumulated in the blood, so it is excreted through the urine. This can lead to problems with the kidneys, central nervous system, heart, and eyes because high blood glucose can damage the blood vessels of these organs. This diseased is managed by adopting a diet low in fat and high in fiber, increasing physical activity, losing excess weight, and not smoking. If this

Insulin resistance is the first physiological change occurring in type two diabetes. In these type two diabetic patients, insulin is unable to move glucose into liver, kidney and muscle cells although insulin is able to attach properly to the cell surface receptors. In order to rectify this, most patients with type two diabetes start secreting normal to very high levels of insulin, which can initially overcome this resistance. After a while, the pancreas cannot keep up with this high insulin production and the cells become resistant to glucose intake. Persistent hyperglycemia or high blood glucose levels are not desirable since this causes damage to the beta cells of the pancreas that produces the insulin hormone. This damage to beta cells further hampers insulin synthesis and patients at this stage are categorized as full-blown diabetic. Such patients consistently show a hyperglycemia state even after hours of fasting ( Hinkle & Cheever,
He said, diabetes mellitus is a chronic disease that occurs when the body doesn 't make enough of insulin, or the body doesn 't use insulin properly. Insulin is a key to regulation of blood glucose in our body. In types II diabetes a condition of when insulin insensitivity as a result of insulin resistance that decreases insulin production and eventual pancreatic beta-cell failure enough insulin to meet body needs. Impairment of beta- cell also can lead to problems with insulin production and resistance that can interfere with the process of glucose uptake in by cells and muscle. This condition leads to a decrease in glucose transport into the liver, muscle cells, and fat cells which can lead to a condition called hyperglycemia. Hyperglycemia occurs when there is a high level of blood glucose levels in our blood (Concepts Advisory Panel (2015) p.742).
The receptors in the cells are covered in the insulin, that allows sugar in the blood to enter the cell for energy production. Diabetes mellitus prevents the cells from using the insulin; therefore, the sugar remains in the bloodstream. the insulin will move into through our cells when pancreas released more insulin that have been transformed from the food that we ate into glucose (sugar).
Type 2 diabetes is a disease that affects how the body uses glucose, a sugar that is the body’s main source of fuel. Your body needs glucose to keep running. Here’s how the system is suppose to work: You get glucose from the food you eat and then the glucose travels into your bloodstream. Then your pancreas makes a hormone called insulin which helps the glucose get into the body’s cells. There for your body gets the energy it needs to function properly. The pancreas is a long, flat gland behind your stomach that helps you digests food, but also makes insulin. Insulin is a hormone that is like a key that opens the doors to the cell of the body. It's like a key because it lets the glucose in, which is only when then the glucose can move out of
Diabetes is a disease that causes their sugar levels to rise higher than average. Type 2 is the most common form of diabetes. It can affect the way our body handles glucose, a kind of sugar, in the patients bloodstream. Over time the pancreas isn't able to keep up and can't make enough insulin to keep their blood glucose at average levels.
Special cells called beta cells located in the pancreas produce a hormone called insulin. The function of insulin is to transform blood sugar, also known as glucose, taken from foods consumed into energy. Insulin moves glucose into cells where it is stored for energy use. Type-two diabetes occurs when the body is incapable of utilizing insulin properly due to the failure of appropriate production from the pancreas. This failure, called insulin resistance, inhibits blood sugar from entering the cells throughout the body and turning it into energy. The glucose is not able to enter the cells, thus creating high levels of sugar in the blood. This elevated sugar levels in the blood is also known as hyperglycemia. In an overweight or obese body, it is harder to utilize insulin correctly due to the increased body fat. Although a normal weight person can develop diabetes, the chances are greater with increased fat in the midsection of the body. A malfunctioning liver, miscommunication between cells, and damaged beta cells could also lead to diabetes. Factors
Diabetes mellitus (DM) is a condition in the body that is related to a faulty metabolism. It means that the body’s metabolism is not functioning properly, which leads to adverse effects in the health. The food we ingest, gets broken down into blood sugar (glucose), which is what fuels our body in the form of energy. This converted glucose needs to enter our cells so that it can be used for energy and growth. And in order for the glucose to enter our cells, there needs to be insulin present, which the beta cells of the pancreas is responsible for producing. This hormone is responsible for maintaining glucose level in the blood. It allows the body cells to use glucose as a main
Diabetes is a chronic disease that severely effects the lives of patients suffering from it. Diabetes occurs when the body’s blood glucose levels are too high (1). There are two main types of Diabetes known as type 1 and type 2 diabetes. Type 1 diabetes occurs when the pancreas is unable to produce the adequate amounts of insulin, and patients with type 1 require daily insulin replacement in order to survive (Martini et al 2015 p. 664). Type 2 diabetes, which is the most common type of diabetes, is often correlated with obesity. The body is able to produce the normal amounts of insulin, but the tissues in the body do not respond appropriately. Type 2 diabetes can be controlled by medication and weight loss, but like type 1, it cannot be cured
To understand diabetes you need to understand what should happen to the food we consume. Any food we eat or drink passes into the stomach and digestive system where it is broken down into carbohydrates, protein, fats, and vitamins. The carbohydrates are then broken down into glucose which is then released into the bloodstream. Once this happens the glucose level increases in the blood so the body’s reaction to that is for the pancreas to release a hormone called insulin. Both the insulin and glucose then travel via the bloodstream to all the cells in the body where the insulin then enables the glucose to enter the cells. We need glucose to reach our cells as it provides fuel for energy.
Diabetes mellitus, or better known as Diabetes, is an endocrine system disorder. In this case, your body is unable to produce enough or any insulin at all. Insulin, produced by the pancreas, has a very important role. When sugar is ingested from food, it is turned into energy for the cells in our body. Without insulin, the transfer of sugar into the cells would be compromised. Insulin is also vital to keep the right balance of sugar in the bloodstream (Hess-Fischl, 2015). If too much insulin is produced, blood sugar levels are decreased resulting in hypoglycemia. Hyperglycemia occurs when the blood sugar levels are increased (Sargis, n.d.).
Well this all starts with knowing what glucose is. Most of the sugar in your body is called glucose. Glucose’s main job is to supply the body with energy. The body breaks down glucose. Releasing energy, water and carbon dioxide. It used by almost all tissues in the body, and is the only fuel the brain can use. If your glucose is too high or low this is caused by diabetes.
