Insulin is necessary to enable carbohydrates in the form of glucose, to pass through the body's cells membrane into the cell, the body's cells need energy in order to function and this applies to every cell in the body. It might be simpler to think of insulin as a door key, it unlocks the door to allow glucose to pass through. Now if there is no insulin, there is no key, so what does the body do, its cells still need energy to function, so it has to find an energy source via a different route. It does this by breaking down protein and it takes this protein from the body's muscles and organs, this is what happens in type 1 diabetes, where you see the characterises of severe weight loss and muscle atrophy. As the body does this it forms Ketones (a by product of breaking down protein for energy) and this gives rise to the characteristic acetone breath found in untreated type 1 Diabetics. Ketones in excess are harmful to the body.
With Type 2 this tends not to happen but the body's cells don't function so well and are essentially tired, so the diabetic will present symptoms of tiredness and lethargy. In some cases Diabetics with type 2 can go on to need insulin injections to manage their disease.
Type 1 Diabetes is often known insulin-dependent diabetes mellitus, IDDM for short, and juvenile diabetes as it often begins in children and young adults and can start suddenly as a result after a viral illness such as the flu.
Type 2 diabetes: results from insulin resistance, a condition in which cells fail to use insulin properly, sometimes combined with an absolute insulin deficiency. Formerly referred to as non-insulin-dependent diabetes mellitus, NIDDM for short, and adult-onset diabetes.
Lastly we have Gestational diabetes: is when pregnant women, who have never had diabetes before, have a high blood glucose level during pregnancy. It may precede development of type 2
There are other forms much rarer such as congenital diabetes, which is due to genetic defects of insulin secretion, cystic fibrosis-related diabetes, steroid diabetes induced by high doses of glucocorticoids, and several forms of monogenic diabetes. But since I wish to focus of the rise of type 2 and the problems this causes I won't discuss this here.
The rise of type 2 diabetes is because of an increase of obesity, not just in adults but this is now being found in overweight children. More and more of the population are eating a poor diet with too much refined sugars and carbohydrates and not enough exercise. Children in particular seem to be spending more time in front of game consuls and TV and computers instead of running around in the fresh air. It's also an easy option to keep them quiet by feeding them bags of artificially flavoured crisps, sweets and sugar laden fizzy drinks, instead of spending time with them or encouraging healthy snacks such as fruit and encouraging them to drink water when they are thirsty. The same goes for adults, in particular when it comes to taking children to school, instead of walking with them, its too easy to drive them, that does not help with carbon foot prints but thats for another blog in due time lol. In yesterday's blog I discussed how eating too much refined carbohydrates created sugar highs and lows facilitating cravings and leading to eating more of these products. Type 2 Diabetes is often initially managed by increasing exercise and dietary modification. If the condition progresses, medications may be needed.
So what does being Diabetic mean for the patient? It means changes in life style especially so for Type 1 diabetics, where blood sugar levels have to be constantly managed and insulin needs to be replaced by regular injections. Food intake, particularly carbohydrates and exercise have to be carefully managed so prevent coma and if untreated can lead to death, its that serious. Management is gravely important as serious health conditions can be the result, such as the loss of limbs, heart attacks and blindness.
Studies in the United Kingdom have shown that the prevalence of impaired glucose tolerance in the 35-65 year age group is about 17%. This is known as pre-diabetes or impaired glucose tolerance. While people with pre-diabetes usually have no symptoms, it’s almost always present before a person develops type 2 diabetes. However, complications normally associated with diabetes, such as heart disease, can begin to develop even when a person has only pre-diabetes.
Once type 2 diabetes develops, symptoms include unusual thirst, a frequent need to urinate, blurred vision, or extreme fatigue. Talk to your doctor to see if you need to be tested for pre-diabetes. By identifying the signs of pre-diabetes before diabetes occurs, you can prevent type 2 diabetes all together and lower your risk of complications associated with this condition such as heart disease.
In type 1 Diabetes the onset is rapid, weight loss, tiredness and complete exhaustion and since the body cannot use or get glucose into the body's cells, it remains in the blood, whereby the kidneys then filter it out of the body into urine, The untreated diabetic's urine has a characteristic sweet aroma. It's full name is Diabetes Mellitis and comes from the latin meaning copious amounts of urine smelling like honey. As the concentration of sugar is very high the body needs to dilute the sugar in the blood. The hypothalamus that area of the brain that is responsible for maintaining homeostasis sends a message to the area of our brains responsible for making us feel thirsty, so in both types of diabetics there will be an increased thirst. Therefore the diabetic will be both thirsty and passing a great deal of urine. Type 2 diabetes is more insidious it creeps up more slowly so the patient might not be aware of an increased thirst or passing more urine but may have noticed they are feeling more tired than usual, or they may notice the development of thrush, as thrush thrives in sugar laden tissues, or skin infections such as boils.
GANGRENE CAN OCCUR THROUGH POORLY MANAGED DIABETES |
Prevention is always better than cure and there is much we can do to prevent type 2 Diabetes, there is no excuse to having this in children who are obese and its tantamount to child neglect allowing children to become so obese in the first place. If we all looked after our health, by eating a healthy balanced diet and taking regular exercise and maintaining a healthy weight, not only would we be helping ourselves to better health but we would be saving the country a huge expense.
