The insulin produced by our bodies moves the sugar in the blood into our cells, which burn the sugar as fuel for the body. In diabetics, however, the lack of insulin (or the resistance to insulin) causes a "starvation" of the cells, which needs the glucose to produce energy. The body's cells will keep signalling that they need sugar, in turn causing diabetics to feel hungry.
But with type 2 diabetics, even when there's sugar in the blood, the body isn't able to effectively transport it into the cells. The more resistant the body is to the effects of insulin, the more insulin it's going to need in order to get the same response.
The body's cells need energy. If it can't get it from sugar, the body will try to convert fats and proteins into sugar. This causes something called ketones to form in the blood. In high enough levels, a condition called ketoacidosis will occur. This can lead to coma or death if left untreated.
Managing your blood sugar levels requires a good diabetes treatment plan developed by your healthcare provider. It will include:
While diabetes isn't exactly "starvation", it does make cells think they're starving. Tight, regimented control of blood sugar levels can help diabetics avoid the many serious complications of the disease.
