I'm a diabetic if my blood sugar is 144 after dinner is that high
How long after dinner?
Nope, That's Perfect.
Normal sugar levels for a diabetic will vary upon when you have eaten. Before a meal it should be between 80-120. Around 2 hours after a meal it should be 160 or less. http://www.medicinenet.com/script/main/art.asp?articlekey=17384
It will normally go up after meals. 140 is not high after you eat
no that's actually a very good level after eating
