So how smooth is the Earth. When billiard balls are manufactured, they aim for a tolerance of 0.22%. The Earth has a tolerance of 0.17%, so itâs actually smoother than a billiard ball. If you could hold the Earth in your hands, it would feel smoother than a billiard ball. But the Earth definitely isnât flat.
Impaired glucose tolerance (IGT) is a pre-diabetic state of hyperglycemia that is associated with insulin resistance and increased risk of cardiovascular pathology.IGT may precede type 2 diabetes mellitus by many years. IGT is also a risk factor for mortality.mpaired glucose tolerance (IGT) is a pre-diabetic state of hyperglycemia that is associated with insulin resistance and increased risk of cardiovascular pathology.
1 A normal blood glucose level is lower than 140 mg/dL (7.8 mmol/L). 2  A blood glucose level between 140 mg/dL and 199 mg/dL (7.8 and 11 mmol/L) is considered impaired glucose tolerance, or prediabetes. 3  If you have prediabetes, you're at risk of eventually developing type 2 diabetes. One hour after drinking the glucose solution, a normal blood glucose level is lower than 180 mg/dL (10 mmol/L). 2  Two hours after drinking the glucose solution, a normal blood glucose level is lower than 155 mg/dL (8.6 mmol/L).
