how long should i wait after eating to test blood sugar
Best Answer: Thirty minutes is too early. Unless you're eating sugar, you won't see any blood sugar spikes thirty minutes after eating. Spikes in blood sugar happen at the 45 minute to 1 hour mark. The two-hour mark is when you should be coming back to normal. She should test exactly two hours after her first bite. She should test after one hour if she's interested in how high she's spiking. Sometimes the one hour matters as much as the two hour.
