Whether high insulin 1 hour after meal is important or not, specifically according to the blood glucose, insulin peak curve and other judgments, can not be generalized, as follows: 1. It does not matter: generally after eating, insulin will rise 0.5 ~ 1 hour after meals, usually increased to 5 ~ 10 times the fasting, if the peak of insulin 1 hour after meals, and insulin levels basically return to normal 3 ~ 4 hours after meals, and blood glucose is normal, then it is a physiological change, and does not require treatment. 2. Relatively important: patients with normal or higher than normal fasting insulin levels, postprandial insulin rise is delayed, the peak in 2 hours or 3 hours, most of the peak in 2 hours, its peak value is significantly higher than the normal value, suggesting that insulin secretion is relatively insufficient, mostly seen in non-insulin-dependent obese people. High insulin at 1 hour after meal is recommended for endocrine specialist outpatient consultation.
