Distinction from regular impaired glucose tolerance Most patients (or animals) with prediabetic type impaired glucose tolerance (serum glucose 140–200 mg/dL at 2 hours after OGTT) are generally not<unk>  because: # Glycosuria is not necessary for mild impaired glucose tolerance (e.g. at approx 140–180 mg/dL range of blood glucose), is necessary for<unk>  (i.e. peak >renal threshold). # In contrast to the commonly seen shallow OGTT curve, amplitude of the pointy spike in<unk>  need not necessarily be restricted to only prediabetic range and in severe<unk>  it may cross 250 mg/dL. In<unk> , by two hours, the glucose not only comes back to pre-diabetic range it may even start shooting below the fasting baseline. # In<unk> , both the upstroke (by 30 minutes) and down stroke (by 2.5 hr) happens quite fast which is unusual for other forms of prediabetes. In most cases of impaired tolerance, glucose levels usually do not come down as quickly, rather lasts for 2 hours or more. Whereas if the<unk>  is due to an early dumping syndrome it may be followed by a late dumping syndrome which may even have a hypoglycemic state. For animal studies, occasionally<unk>  is written as synonymous for impaired glucose tolerance but mostly in the right context of gastrectomy, thus actually implying its narrower meaning than impaired glucose tolerance.
