If you have diabetes, you may be facing difficulty managing the lows and highs of this disease. Extremely high or low blood sugar levels can pose a danger to your overall health, necessitating prompt action.
You may have wondered, ‘What level of blood sugar is dangerous?’ It’s a range that is outside the healthy target. This blog will discuss this topic in detail.
What Is A Dangerous Blood Sugar Level?
For diabetic patients, extreme fluctuations in blood sugar can be dangerous for their overall health. If you have diabetes or are pre-diabetic, checking your blood sugar regularly is important. It will help you determine if your blood sugar level is too low or too high. It also helps determine your next course of action, such as taking a corrective dose of insulin or eating something to raise your glucose levels. But what blood sugar reading is dangerous?
Both too-low (hypoglycemia) and too-high (hyperglycemia) blood sugar levels can lead to many health complications. If your blood sugar level remains too low or too high for extended periods, certain physiological symptoms, such as excessive hunger, thirst, frequent urination or sudden weight loss, can arise. However, complications can even occur without any symptoms. So, it is important to monitor your blood sugar levels.
If your blood sugar is higher than 300 mg/dL with high to moderate ketones for a prolonged period and you’re unable to get your blood sugar down, you should seek emergency medical attention. Diabetes patients with above 600 mg/dL blood sugar levels have a higher chance of falling into a diabetic coma. In this situation, your blood becomes syrupy and thick, and excess sugar passes into your urine. This triggers a filtering process that draws large amounts of fluid from your body. This condition is known as hyperosmolar hyperglycaemic syndrome. It is life-threatening, and you should immediately call your doctor.
Low blood sugar can be dangerous if left untreated. For patients with diabetes, low blood sugar is anything below 70 mg/dL. Readings under 40 mg/dL are considered very low, may be potentially fatal and extremely dangerous. In the worst cases, it can even result in death and diabetic coma. However, in most cases, it won’t cause permanent complications unless you experience a traumatic brain injury and brain swelling from falling into a diabetic coma. If you’re experiencing a severely low blood glucose level and can’t swallow liquids or chew food, you will need an emergency glucagon shot.
Diabetes alert dogs and glucose monitoring systems can help you detect when your blood glucose level is low before it becomes life-threatening. So now that you know what an unsafe sugar level in blood is, you should take immediate action to avoid any complications.
Conclusion
Get immediate medical help if your blood sugar becomes too low or too high. Regular monitoring, timely treatment, and medical supervision are essential for managing diabetes effectively. You should also consider purchasing health insurance to access the health care and medical supervision required to manage this disease.
