In the case of Type 1 diabetes, the body does not produce any insulin, thereby leaving the body unable to break down and use or store glucose properly.

Diabetes is an incurable condition in which the body cannot control blood sugar levels, because of problems with the hormone insulin. Under normal circumstances, the hormone insulin, which is made by your pancreas, carefully regulates how much glucose is in the blood.
After a meal, the amount of glucose in your blood rises, which triggers the release of insulin.
Type 1 diabetes is an autoimmune condition, and the immune system attacks the cells of the pancreas. The exact mechanisms that lead to Type 2 diabetes are not fully understood, but an underlying genetic susceptibility is usually present. Gestational Diabetes - During pregnancy, some women experience heightened blood sugar levels and can't produce enough insulin to absorb it all. Maturity onset diabetes of the young (MODY) - Caused by a mutation in a single gene and is also very rare.
If people living with Type 1 diabetes don't receive treatment they can develop very high blood sugar levels - hyperglycaemia - within days. At the same time, the body starts breaking down fat for fuel to counter the low levels of sugar available to the cells. Those with Type 1 can also suffer a dangerous complication of treatment known as hypoglycaemia, which can cause a coma. If treatment doesn't effectively control high blood sugar levels, it leaves a person with diabetes more vulnerable to infections.
Type 2 diabetes tends to develop more gradually, which is one of the reasons why medical professionals think that so many cases go undiagnosed. In the long-term, diabetes raises the risk of many conditions, including peripheral vascular disease (when the arteries to the extremities are damaged by atherosclerosis) and peripheral nerve damage. Diabetes mellitus, often simply referred to as diabetes, is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells.
When you have type 2 diabetes, your fat, liver, and muscle cells do not respond correctly to insulin.
An overview Nearly 400 million people worldwide are living with diabetes, and that number is expected to jump to almost 600 million by 2035, according to the International Diabetes Federation.


Insulin Resistance Vs Insulin Sensitivity When it comes to insulin and insulin sensitivity vs insulin resistance, you are always on a continuum of how insulin sensitive your are are and what tissues are most effective at absorbing glucose. This entry was posted in Misc, Nutrition and tagged carbohydrates, carbs, diabetes, insulin.
As the illustrations below show, a person without diabetes is able to use insulin to break down glucose which is then used or stored by organs in the body. In Type 2 diabetes, the body does not produce enough insulin or respond effectively to the insulin it does produce. It is available at newsstands, hospitals and clinics throughout Winnipeg, as well as McNally Robinson Books. Insulin stimulates cells all over your body to absorb enough glucose from the blood to provide the energy, or fuel, that they need. It tends to affect people before the age of 40, and often follows a trigger such as a viral infection. In most cases it develops between the 14th and 26th week of pregnancy, known as the second trimester, and disappears after the baby is born. Because there is no insulin to drive the sugar from the blood into the cells, the kidneys try to remove the excess glucose. This leads to toxic levels of acids building up in the blood - a life-threatening condition known as ketoacidosis. This occurs when blood sugar levels fall dangerously low as a result of taking too much insulin, or sometimes by skipping a meal.
Over time it can also damage the small blood vessels and nerves throughout the body, including the smaller vessels at the back of the eye, which can result in blindness, and the kidneys, leading to kidney failure. This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger). Insulin is needed to move blood sugar (glucose) into cells, where it is stored and later used for energy. For many people, diabetes can be controlled with diet, exercise and, often, insulin or other drugs. At its most basic, diabetes is a condition in which the body cannot regulate or properly use sugar (called glucose) in the blood. Stem cells are helping us to explore the intricate way in which our bodies process sugar and to answer some important questions about the root causes of diabetes: In type 1 diabetes, why does the immune system begin to attack beta cells and not other cells in the pancreas or in other organs or tissues?
Developing and testing a truly effective stem-cell based treatment for diabetes will take years. As a result, glucose levels in the blood can increase unchecked, causing permanent changes in the structure and function of the body's organs. It can also be produced by carbohydrates such as potatoes, pasta or bread when they are digested and broken down. In Type 2 diabetes, either the pancreas cells do not make enough insulin, or the body's cells do not react properly to it.


The condition is then triggered by lifestyle factors - such as obesity - and it usually appears in people over the age of 40. The brain requires a constant supply of glucose from the blood otherwise it can't function properly. However, complications from diabetes can be serious and include kidney failure, nerve damage, vision loss, heart disease and a host of other health issues. The pancreas, which helps the small intestine digest food, has hundreds of thousands of cell clusters called islets of Langerhans where beta cells live.
When the beta cells are damaged, they don’t produce insulin, or at least not enough insulin. Researchers are looking at ways to restore the number of functional beta cells in patients with diabetes, pursuing both the replacement of lost beta cells and the protection of beta cells from further damage. Beta cells produce insulin, which is released into the bloodstream when blood sugar levels reach a certain threshold. Other cells never get the signal to take up sugar, so they don’t get the energy they need to function properly, and high sugar levels in the blood end up causing damage to the kidneys, eyes, nervous system and other organs.
They struggle to maintain the optimal balance found in healthy bodies and need to monitor their blood sugar several times a day. The insulin signals other cells in the body to take up sugar, the primary energy source for all the body’s cells. The advent of the insulin pump has greatly improved treatment for some people, enabling the delivery of individualized doses or a steady stream of insulin, but it cannot precisely mimic the healthy human body’s constant, sophisticated monitoring and adjusting of insulin production and blood sugar levels. While you will be able to view the content of this page in your current browser, you will not be able to get the full visual experience. The beta cells produce more insulin to signal the other cells, but eventually are not able to compensate.

As with type 1, high blood sugar levels in type 2 diabetes can cause serious damage to the body. Beta cells can do this in the pancreas, but usually very slowly, and less and less as we get older. Researchers are looking for drugs that might enhance this self-renewal as a possible treatment for people with type 2 or early-stage type 1 diabetes. There are some clinical trials underway to test whether blood stem cells or mesenchymal stem cells from the bone marrow might alter or re-set the immune system so that it no longer attacks the beta cells. However, the mechanisms underlying how this use of these cells would work are not well understood, and further research is needed to establish whether any of these approaches will prove safe and effective.
