What Blood Sugar Levels Are Dangerous?
So, what exactly is considered a dangerously high blood sugar level? This is a crucial question for anyone managing diabetes. Generally, blood sugar levels that are consistently above 250 mg/dL (milligrams per deciliter) are considered high and warrant attention. However, the specific level that becomes “dangerous” can vary depending on individual factors such as age, overall health, and the presence of other medical conditions.
For many people with diabetes, a blood sugar reading above 300 mg/dL is a sign of a serious problem. At this level, you’re more likely to experience symptoms of hyperglycemia, and the risk of developing diabetic ketoacidosis (DKA) increases. DKA is a life-threatening condition that occurs when your body starts breaking down fat for energy because it doesn’t have enough insulin to use glucose (sugar) from your blood. This process produces ketones, which can build up to dangerous levels in your blood and urine.
It’s important to note that blood sugar levels can fluctuate throughout the day. After eating, it’s normal for your blood sugar to rise. However, if your blood sugar remains consistently high, especially above 250 mg/dL, it’s time to take action. Regular monitoring of your blood sugar levels is key to identifying and addressing high blood sugar before it becomes dangerous.
Talk to your doctor or diabetes educator about what blood sugar range is right for you. They can help you set individual targets based on your specific needs and health goals. They can also provide guidance on how to adjust your medication, diet, and exercise to keep your blood sugar within your target range.
Why Are High Blood Sugars Dangerous?
High blood sugar, or hyperglycemia, isn’t just a number on a glucometer. It can have serious consequences for your health if it’s not managed properly. When your blood sugar is consistently high, it can damage blood vessels and organs throughout your body. This damage can lead to a range of complications, some of which can be life-threatening.
One of the most serious risks of high blood sugar is diabetic ketoacidosis (DKA). As mentioned earlier, DKA occurs when your body starts breaking down fat for energy because it doesn’t have enough insulin. This process produces ketones, which are acidic chemicals that can build up in your blood. Symptoms of DKA include nausea, vomiting, abdominal pain, fruity-smelling breath, and rapid breathing. If left untreated, DKA can lead to coma and even death. This is more common in Type 1 diabetes, but can occur in Type 2 as well.
Even if you don’t develop DKA, long-term high blood sugar can still cause significant damage to your body. It can increase your risk of heart disease, stroke, kidney disease, nerve damage (neuropathy), eye damage (retinopathy), and foot problems. These complications can significantly impact your quality of life and may require extensive medical treatment.
For example, nerve damage can cause pain, numbness, and tingling in your hands and feet. This can make it difficult to walk, sleep, or perform everyday tasks. Eye damage can lead to blurred vision, cataracts, glaucoma, and even blindness. Kidney disease can eventually lead to kidney failure, requiring dialysis or a kidney transplant.
The good news is that you can significantly reduce your risk of these complications by keeping your blood sugar levels within your target range. Regular monitoring, a healthy diet, regular exercise, and adherence to your medication plan are all essential for managing your blood sugar and protecting your health.
How Do You Know If Your Blood Sugar Is Dangerously High?
Recognizing the signs and symptoms of high blood sugar is crucial for taking timely action and preventing serious complications. While the only way to know for sure what your blood sugar level is is to test it with a glucometer, there are several common symptoms that may indicate hyperglycemia.
One of the most common symptoms of high blood sugar is increased thirst. When your blood sugar is high, your body tries to get rid of the excess glucose through urine. This can lead to dehydration, which triggers your thirst mechanism. You may find yourself drinking more water than usual and still feeling thirsty.
Another common symptom is frequent urination. As your body tries to flush out the excess glucose, you may need to urinate more often, especially at night. This can disrupt your sleep and lead to fatigue.
Other symptoms of high blood sugar include blurred vision, headaches, fatigue, and slow-healing sores or cuts. You may also experience dry, itchy skin and unexplained weight loss. In some cases, high blood sugar can also cause nausea, vomiting, and abdominal pain.
If you experience any of these symptoms, it’s important to check your blood sugar as soon as possible. If your blood sugar is consistently high, even if you don’t have any symptoms, it’s important to talk to your doctor or diabetes educator. They can help you adjust your treatment plan to better manage your blood sugar levels.
It’s also important to be aware of the symptoms of DKA, which can develop quickly when blood sugar is very high. These symptoms include nausea, vomiting, abdominal pain, fruity-smelling breath, and rapid breathing. If you experience any of these symptoms, seek immediate medical attention.
Tips for Avoiding High Blood Sugar
Preventing high blood sugar is always better than treating it. By making some lifestyle changes and following your doctor’s recommendations, you can significantly reduce your risk of hyperglycemia and its complications. Here are some tips for avoiding high blood sugar:
- Monitor your blood sugar regularly: Regular blood sugar monitoring is the cornerstone of diabetes management. Check your blood sugar as often as your doctor recommends, and keep a record of your readings. This will help you identify patterns and make adjustments to your treatment plan as needed.
- Follow a healthy diet: A healthy diet is essential for managing blood sugar. Focus on eating whole, unprocessed foods such as fruits, vegetables, whole grains, and lean protein. Limit your intake of sugary drinks, processed foods, and saturated and trans fats.
- Exercise regularly: Regular physical activity can help lower blood sugar and improve your body’s sensitivity to insulin. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Take your medication as prescribed: If you take medication for diabetes, it’s important to take it exactly as prescribed by your doctor. Don’t skip doses or change your dosage without talking to your doctor first.
- Manage stress: Stress can raise blood sugar levels. Find healthy ways to manage stress, such as exercise, yoga, meditation, or spending time with loved ones.
- Stay hydrated: Dehydration can raise blood sugar levels. Drink plenty of water throughout the day to stay hydrated.
- Get enough sleep: Lack of sleep can affect blood sugar levels. Aim for 7-8 hours of sleep per night.
What to Do When Your Blood Sugar Is Dangerously High
Even with the best management strategies, high blood sugar can still occur. Knowing what to do when your blood sugar is dangerously high can help you prevent serious complications. Here are some steps to take if your blood sugar is above your target range:
- Check your blood sugar: The first step is to confirm that your blood sugar is indeed high. Check your blood sugar with a glucometer to get an accurate reading.
- Test for ketones: If your blood sugar is above 250 mg/dL, it’s important to test for ketones. You can use over-the-counter ketone strips to test your urine. If you have moderate or large amounts of ketones in your urine, it’s important to contact your doctor or seek immediate medical attention.
- Drink plenty of water: Dehydration can worsen high blood sugar. Drink plenty of water to help flush out the excess glucose and prevent dehydration.
- Take your medication: If you take insulin, you may need to take a correction dose to bring your blood sugar down. Talk to your doctor or diabetes educator about how to adjust your insulin dosage when your blood sugar is high. If you take other diabetes medications, continue to take them as prescribed.
- Exercise with caution: Avoid strenuous exercise when your blood sugar is high, especially if you have ketones in your urine. Exercise can sometimes raise blood sugar levels even higher.
- Monitor your blood sugar closely: Check your blood sugar every few hours to see if it’s coming down. If your blood sugar remains high or continues to rise, contact your doctor or seek medical attention.
