What are bad levels of blood sugar?

The recommended fasting glucose range for a person without diabetes is 70 to 130mg/dL. (The standard for measuring blood glucose is “mg/dL” which means milligrams per deciliter.) If your blood glucose level after an eight-hour (or longer) fast is above 130mg/dL, that’s called fasting hyperglycemia.

What is alarming level of blood sugar?

In general, a blood sugar reading of more than 180 mg/dL or any reading above your target range is too high. A blood sugar reading of 300 mg/dL or more can be dangerous. If you have 2 readings in a row of 300 or more, call your doctor.

When your sugar level is over 400?

Glucose builds up in the blood if there is not enough insulin to move glucose into your cells. During an episode of ketoacidosis, it is common for blood sugar to rise to a level over 400 milligrams per deciliter. When blood sugar levels are so high, some sugar “overflows” into the urine.

Is 140 a good blood sugar level?

A normal blood sugar level is less than 140 mg/dL. If the level is between 140 and 199 mg/dL, the patient has impaired glucose intolerance, also called pre-diabetes. A level of 200 or greater indicates diabetes.

What are good and bad blood sugar levels?

A normal result for fasting blood glucose ranges from 70 – 100 mg/dL . According to criteria set by the American Diabetes Association, a higher than normal fasting blood sugar between 100 to 125 mg/dL (5.6 to 6.9 mmol/L) may indicate prediabetes. This shows an increased risk of developing Type 2 diabetes.

What level should your blood sugar be?

The normal blood sugar level varies from 72 mg/dl to about 140 mg/dl. Before a meal, the average sugar level should be around 80 to 120 mg/dl.

Is 120 a good sugar level?

Although 120 is not too high, ideally you do want to gain very good control of your blood sugar levels by following a healthy diet and doing regular exercise. If you can get your fasting level between 90-100 mg/dl (5-5.5 mmol/l), and your 2 hour reading between 120-140 mg/dl (6.6-7.8 mmol/l) then that is optimal.
