Some people have medical conditions which make their blood sugar levels be at a different range then normal.
For the most part people use the same scale to determine what normal blood sugar levels are and what they should be at. When waking up before you eat breakfast your blood sugar level should be in between eighty to one hundred and twenty. Two hours after a meal it should be at one hundred and sixty or less. When you go to bed your blood sugar level should reach between one hundred to one hundred and forty.
Sometimes if you have an abnormal blood sugar level your doctor will put you on medication to regulate your levels. It is also important to watch what you eat. Make sure you keep track of how much sugar you are putting into your body, especially if you are diabetic.
Many people have really high blood sugars due to eating too many sweets or having a medical condition that makes their levels reach higher then normal. It is important to monitor your blood sugar levels and keep them at a normal level for your body and age. If you have diabetes in your family then you need to make sure that you really watch your levels for health reasons.
