When to Head to the Hospital: Understanding High Blood Sugar Levels

Ever wondered when your blood sugar levels should have you heading to the emergency room? It’s a question that’s likely crossed the minds of many dealing with diabetes or pre-diabetes. In this article, I’ll delve into the specifics of high blood sugar levels and the critical point at which medical intervention becomes necessary.

Understanding your blood sugar levels and how to manage them can be a lifesaver, literally. We’ll discuss the signs and symptoms that should alert you, and when it’s time to seek immediate medical help. It’s essential knowledge for anyone with diabetes, or those caring for someone with the condition. So, let’s get started and demystify this crucial health topic.

What is High Blood Sugar Level?

Before delving deeper into when it’s time to seek hospitalization due to high blood sugar, let’s first establish what ‘high’ really looks like in terms of sugar levels. Broadly speaking, blood sugar, or glucose, is what your body uses for energy. Insulin, a hormone, helps your cells absorb this glucose. However, when your body doesn’t produce enough insulin or becomes resistant to it, the glucose stays in your bloodstream leading to high sugar levels. This condition, known as hyperglycemia, proves harmful over time.

Understanding numbers is vital!

Generally, for individuals without diabetes, normal fasting blood sugar levels range from 70 to 100 milligrams per deciliter (mg/dL). After meals, it may shoot up slightly but won’t exceed 140 mg/dL.

high blood sugar levels can significantly vary among individuals, but to put it simply, for those with diabetes:

Condition Blood Sugar Level (mg/dL)
Diabetes Over 130 (Fasting)
Over 180 (After Meals)
Hyperglycemia 180 or higher (Consistently)

Take note that these numbers are only guidelines. For some, high blood sugar could still mean different numbers. So, personal targets may vary depending on various factors such as age, duration of diabetes, and presence of other health conditions.

Now that we have a rough idea of what high blood sugar level is, in the next segment, let’s look closely at the sneaky culprits behind fluctuations in blood sugar levels, and why it’s critical to keep them in check.

Understanding Blood Sugar Levels

After setting a strong fundamental foundation about blood sugar levels in the previous section, it’s time to delve deeper. Understanding blood sugar levels isn’t just about knowing the numbers. It’s crucial to comprehend the factors affecting these fluctuations, and the significance of managing them effectively.

Blood sugar levels are the amount of glucose present in your bloodstream at any given moment. This glucose is your body’s main source of energy. It comes from the food we eat and is also produced in the liver. Our bodies rely on insulin, a hormone made in the pancreas, to allow glucose into the cells where it’s used for energy. In condition like diabetes, this process is disrupted causing an imbalance in blood sugar levels.

Your doctor would often recommend regular blood glucose checks, particularly if you’ve got diabetes. There’s a range of normal blood sugar levels. It’s standard for your levels to fluctuate throughout the day. Stress, diet, medication, physical activity, and more, each impact blood glucose in unique ways.

Average Blood Sugar Levels Non-Diabetic Pre-Diabetes Diabetes
Fasting 70 – 99 mg/dl 100 – 125 mg/dl 126+ mg/dl
2 hours after meals Less than 140 mg/dl 140 – 199 mg/dl 200+ mg/dl

Understanding and recognizing these patterns in your own blood sugar levels, as well as knowing when and how to act when levels are high or low, is key to managing diabetes.

So, although you might think of maintaining blood sugar levels simply as sticking to a diet or a medication routine, it’s also about understanding your body’s responses. It involves adapting to a variety of situations to keep yourself within a safe range while also enjoying a full, active life.

I can’t stress enough how important it is to keep blood sugar levels in check. Consistently high levels pose serious health risks including damage to the heart, kidneys, eyes and nerves.

Signs and Symptoms

Knowing the signs and symptoms of high blood sugar, or hyperglycemia as it’s scientifically known, is essential. It could quite literally be the difference between life and death. Here are some key symptoms to look out for:

  • Constant thirst and frequent urination: One of the earliest signs of high blood sugar is excessive thirst that’s hard to quench and frequently needing to go to the bathroom.
  • Persistent hunger: Even after eating, you might still feel persistently hungry. This is because the glucose isn’t being efficiently transported from your bloodstream into your cells for energy.
  • Unexplained weight loss: Despite eating more, you might experience sudden or unexplained weight loss as your body starts using fats for energy, rather than glucose.
  • Fatigue and weakness: Without sufficient glucose getting into your cells, you’re likely to feel drained and tired.
  • Blurry vision: High sugar levels can cause fluid in your body to shift into your eyes, distorting your vision.

While these are common symptoms, it’s important to remember they can also be indicative of other health issues. They should therefore not be used as a definitive diagnosis. If you’re experiencing these symptoms, it’s advisable to get a blood sugar test from a healthcare professional.

Health conditions can manifest differently in different people. Progression and severity of symptoms may vary, and not everyone with high blood sugar will experience the same signs. It also bears noting that a seemingly healthy individual can also have high blood sugar levels, a condition known as ‘silent diabetes’.

So, recognizing any of these signs early and acting on them could potentially prevent serious damage to your health. If you’re unsure about your symptoms, reaching out to a doctor, nurse, or pharmacist for advice is crucial. Prompt intervention can often make a significant difference in managing high blood sugar levels and minimizing the risk of complications.

When to Seek Medical Help

It’s crucial to recognize when hyperglycemia crosses into the dangerous territory. Despite some overlapping signs, the timing for when to seek medical assistance varies depending on the person’s overall health, age, and the presence of other underlying conditions. But some general guidelines can help ensure that treatment is sought in time.

If your fasting glucose level exceeds 126 milligrams per deciliter (mg/dL) on two separate tests, you likely have diabetes. Glucose levels in this range or higher mean immediate medical help is required. Also, an urgent hospital visit is necessary if the glucose level hits 200 mg/dL or more after two hours into a glucose tolerance test.

A quick reference table might help you grasp this:

Condition Glucose level (mg/dL)
Healthy Range < 100
Prediabetes 100 – 125
Diabetes ≥ 126
Hyperglycemic Crisis ≥ 200

Remember, these are just broad indicators. If you’ve been diagnosed with diabetes and your sugar levels are progressively increasing despite medication, it’s time to seek immediate medical help.

Another red flag is if you experience hyperglycemic hyperosmolar syndrome. Symptoms of this potentially lethal condition include extreme thirst, fever, dry skin, and confusion, followed by lethargy, stupor, and ultimately, loss of consciousness. Without an intervention, it can lead to seizures, coma, or in worst cases, death.

Facing hyperglycemic crises, such as diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome needs immediate medical attention. It concerns not only those with diagnosed diabetes but also people finding symptoms with undiagnosed diabetes or pre-diabetes. The severity can range from confusion or discomfort to life-threatening emergencies.

So, knowing your blood glucose levels and understanding the indications of potential problems is essential. Stay mindful of these blood sugar levels and corresponding symptoms and don’t hesitate to seek professional help when they occur. This vigilance could be the difference between normal health and grave consequences. Remember, an early diagnosis can pave a way for a better sugar management and a healthier life.


I’ve walked you through the critical points of when it’s time to head to the hospital for high blood sugar. Remember, if fasting glucose levels are above 126 mg/dL or if a glucose tolerance test results in 200 mg/dL or more, it’s time to seek immediate medical help. Don’t overlook symptoms of hyperglycemic hyperosmolar syndrome either – it’s a severe, life-threatening condition. Being aware of your blood glucose levels and understanding the signs of trouble can save your life. Always seek professional help when in doubt. Early diagnosis is key to managing your sugar levels effectively, leading to a healthier life. Stay informed, stay vigilant, and stay healthy.
