Dangerous Blood Sugar Levels: When to Seek Medical Help

Written by - Editorial Team
Medically Reviewed by - Dr Deepika Patel

Blood sugar levels are a vital indicator of your overall health. Maintaining them within a normal range is essential for the proper functioning of your body. Blood sugar, also known as glucose, is the primary energy source for your cells, and when these levels go too high or too low, it can lead to serious health issues. Understanding dangerous blood sugar levels and knowing when to seek medical help is crucial for everyone, especially those at risk of diabetes.

What is Blood Sugar?

Blood sugar refers to the amount of glucose present in your bloodstream. Glucose comes from the food you eat, particularly carbohydrates, and is used by your body to produce energy. Insulin, a hormone produced by the pancreas, helps glucose enter your cells. If this process is disrupted, your blood sugar levels can become imbalanced.

Blood Sugar Causes

Several factors can influence your blood sugar levels. These include:

  • Diet: Consuming foods high in sugar or refined carbs can spike blood sugar.
  • Lack of physical activity: Exercise helps your body use glucose efficiently.
  • Stress: Physical or emotional stress can increase glucose production.
  • Medical conditions: Type 2 diabetes, hormonal disorders, and infections can affect sugar levels.
  • Medications: Certain medications may raise or lower blood sugar.

Understanding Dangerous Blood Sugar Levels

Knowing what constitutes dangerous glucose levels is essential. While the exact numbers may vary slightly depending on medical guidelines, the following ranges provide a clear reference:

  • Fasting blood sugar: Above 126 mg/dL may indicate diabetes.
  • Random blood sugar: Levels above 200 mg/dL with symptoms suggest high blood sugar.
  • Severe high blood sugar (hyperglycemia): Levels consistently above 300 mg/dL require urgent medical attention.

Dangerous blood sugar levels are not always obvious. Some people may experience mild symptoms while others may have severe complications.

Signs of High Blood Sugar

Recognizing the signs of high blood sugar is important for early intervention. Watch out for the following symptoms:

  • Frequent urination and increased thirst
  • Fatigue and weakness
  • Blurred vision
  • Headaches
  • Unexplained weight loss
  • Nausea or vomiting

If you notice these signs, it is important to check your blood sugar levels and consult a doctor.
