What Are Dangerous Blood Sugar Levels?

Dangerous blood sugar levels are anything above 160 mg/dL and below 60 mg/dL. These are the critical thresholds when you need to call the doctor and act without delay to either lower or raise you blood glucose in a safe manner. However, this does not mean that anything between 60 and 160 at any time is OK. Normal ranges for preprandial (fasting) and postprandial (2 hours after meal) blood sugar levels are different and what is a normal, healthy reading 2 hours after meal is a dangerous or even an emergency zone for fasting readings.

The dangerous blood sugar levels that indicate insulin resistance and pre-diabetic condition are the fasting readings that don’t fall below 110 mg/dL. High fasting glucose readings are the most ominous because they indicate your body’s inability to produce enough insulin to break down glucose. If your fasting reading is above 126 mg/dL you’ll be diagnosed with diabetes.

Today, most doctors will say that your blood sugar level needs to be below 90 before breakfast (fasting levels), and not exceed 120 two hours after eating - these are the target maximums recommended to maintain. Although some doctors will say normal ranges are 100 and 140, you’d better have 80 and 110 as your target levels, even though healthy blood sugar levels suggested by the Association of Clinical Endocrinologists and ADA are also higher. Today’s accepted normal blood sugar levels may be officially put to the “dangerous” zone on the chart tomorrow or some years later. Please note that it’s not just rising above a certain critical level but also staying at an elevated level for too long may be very dangerous. Diabetes takes decades to develop and through all these years dangerous, irreversible changes in your body cells occur because your glucose levels are higher than healthy, although still within currently acceptable non-diabetic or pre-diabetic ranges. It will be too late to act then so act now - keep an eye on your blood sugar levels to make sure they don’t move to the dangerous scale. Just keep in mind that most healthy people have their fasting levels slightly above 70.

If you are over 40, and pastry, refined and sugar containing foods are the bulk of you diet, and you don’t monitor your blood glucose levels, you are in the risk group for dangerous blood sugar number, even if your current readings are within safe ranges. The problem is that its only diabetics who monitor their blood sugar levels. As to non-diabetics, they may be totally unaware that their blood sugar levels are about to enter the danger zone. If you experience any of the high blood sugar symptoms and you know your diet is not perfectly healthy you need to take a blood sugar test.

Dangerous Blood Sugar Levels For Diabetics

240 mg/dL is an accepted critically dangerous reading that combined with ketones in your urine points to the upcoming diabetic coma, which typically occurs when glucose level go above 300 mg/dL and remain untrated . Such a condition requires urgent measurers to be taken by the doctor to lower blood sugar levels to a safer range. Attention! Don’t exercise before testing your blood sugar! Although excusing is a common way to lower blood sugar, a workout while having ketones in your urine can produce the opposite effect and get you into the diabetic coma (ketoacidosis, typical for type 1 diabetes), as the American Diabetes Association warns. Ketones is a waste product of breaking down fat that remains in your blood stream as your body in unable to get rid of it. You body starts to break down fat for energy when it’s unable to get the energy from breaking down glucose because of insufficient insulin. HHNS is another complication of dangerously high blood sugar levels (abouve 600 mg/dL), typical for type 2 diabetes. You body tries to remove excess glucose from be body with urine, which causes severe dehydration and death.

Dangerous Blood Sugar Levels In Pregnancy

For pregnant women, dangerous blood sugar levels are the same but keeping within normal ranges is more important because entering the risk ranges may do harm to the baby.

Dangerous Low Blood Sugar Levels

Not just high but also low blood sugar levels may be dangerous. This condition called gypoglycemia may occur from either too little food or excessive activity, when you blood sugar level fall below 70 mg/dL. Symptoms of gypoglycemia are problems with coordination, dizziness, tingling in the limbs, being confused, loss of consciousness.
