Hyperglycemia:

Diabetes is a disability, a condition wherein the body struggles to regulate the absorption of sugar and proper production and absorption of insulin.  In type I diabetes, the kind I have, the body is absorbing insulin fine, but the pancreas is not producing enough to remove adequate sugar from the bloodstream, and is not releasing the sugar properly when blood sugar is low.  The balance of blood sugar is needed because too much weakens the blood cell walls and damages tissue, but too little doesn't give enough energy for daily necessity, especially brain activity.  As such, Hyperglycemia, the over-abundance of sugar in the bloodstream, is extremely dangerous.  As it damages tissue and blood, it increases the risk of stroke and heart attack, as well as seizures.

The unfortunate thing is that taking too much insulin beyond what is needed makes the body build it up as fat, which causes an increase in resistance.  Thus, one needs to not take too much insulin beyond what is needed, or it will be less effective in the future until the fat is exercised off.  As this is more difficult than just eating less, it becomes a necessity to be careful with how many carbohydrates someone with diabetes eats in a day, and if they are type I, how much insulin they use as a result.

Part of the problem many diabetics have with this is loving to eat out, or eat with friends and family, but having no idea how many carbs their meal has.  They can estimate it if they get used to making food on their own that is similar, or by asking friends and family to keep the ingredient labels and such so as to calculate it out, but restaurants typically don't have such things.  The more one tries to avoid eating out, however, the more stigma there is for not eating with friends, family and co-workers, or for turning down free food.  This, in addition to many people disliking the sight of the injections being done or being afraid of needles and becoming queasy, make some ask questions such as why they don't take a pill form, or have a pump instead that is more easily concealed and supposedly makes things easier.

There are no pill forms of insulin as that wouldn't properly integrate into the body with how it is produced, and the pumps are not only more expensive but still require the same amount of regulation as the needles themselves due to needing to know how many carbohydrates are being consumed and then inputting it into the machine for how many units to pump out.  By and large, this takes just as much time as using the needles directly, and yet when explaining this to some people, they just turn their noses at even kindly having this explained to them because someone they know or have heard of swears by the pump.  In the case of understanding after it is explained, that was just ignorance and now it has been replaced with knowledge.  In the case of those who bristle and sneer at explanations, this is stupidity.
