what is the normal blood sugar level for adults?
When you measure blood sugar after fasting for at least eight hours, commonly before breakfast, this is called normal fasting blood sugar level. And you must look for these ranges: 70-100 mg/dl. After taking a meal, your blood sugar will rise. In a normal adult it will not pass the ranges of 135-140 mg/dl. Now, you can see that there exists only a narrow range of blood sugar all the day for a normal adult.
