What is Glucose?

Ever wondered why glucose is vital to your health? Glucose is the body's main source of energy, fueling everything from brain function to muscle contraction. You'll learn how your body creates and uses glucose, its role in your well-being, and the importance of keeping proper levels of glucose in your bloodstream.

What is glucose?

What is glucose? Glucose is a simple sugar that you get from the foods you eat, playing a crucial role as an energy source for your body's cells. It circulates in your bloodstream, supporting vital bodily functions and overall health.

How does your body use glucose?

Your body carefully organizes the conversion of food into glucose, which is then used to power every cell. Think of glucose as the premium fuel your body needs to run efficiently.

It all starts when you digest carbohydrates from your plate—think sugars and grains—and they break down into glucose. This glucose then zips through your bloodstream and arrives at cells waiting for their next energy boost.

• Digestion: Carbs break down into glucose.
• Absorption: Your intestines absorb glucose into the bloodstream.
• Metabolism: The liver can also transform other nutrients into glucose if necessary.
• Storage: Extra glucose gets stored as glycogen, and if glycogen stores are replete - as fats.
• Regulation: Insulin moderates blood glucose levels.

What happens when glucose levels fluctuate?

Balance is vital when it comes to blood glucose. Too high, and you're dealing with hyperglycemia, an indicator of prediabetes or diabetes.

Too low? That's hypoglycemia, leaving you shaky, irritable, and craving a quick sugar fix. Here's how your body strives for that sweet spot:

• Insulin release: Your pancreas releases insulin to reduce high glucose levels post-meal.
• Glycogenolysis: When levels dip, your liver turns stored glycogen back into glucose.
• Balanced levels: Ideal blood sugar levels keep you energetic and focused.

What are normal blood glucose levels?

Pinpointing normal blood glucose levels is like finding the perfect thermostat setting—it's individual, but there are healthy limits and ranges to consider as adults. Here's a general guide:

• Fasting blood glucose (between meals): 80-130 mg/dL
• Postprandial glucose (after a meal): <180 mg/dL , specific targets for people with gestational diabetes or existing diabetes

What influences your blood sugar?

Blood sugar's enemy isn't just sweets; it's a mix of lifestyle elements that can send your levels on a rollercoaster ride. Here are some factors that influence your blood sugar:

• Physical activity: Low physical activity is considered one of the main risk factors for hyperglycemia, prediabetes, and type 2 diabetes.
• Sleep quality: Needed for appetite control and blood sugar balance.
• Caffeine: Too much can spike levels.
• Stress: A notorious glucose booster.
• Hydration: Necessary for level stability.
• Time of day: Morning levels can be stubborn.

Why watch for signs of unbalanced blood glucose levels?

Whether you're a hardworking health tracker or you have diabetes in the picture, watching your levels is important to stay healthy. High or low numbers could signal a need to change your diet, exercise routine, or meds.

When should you be concerned?

Rapid heartbeat, blurred vision, or a case of the jitters? These could be cries for help from your blood sugar balance.

If these or other symptoms start, think about when you last ate something. It might be time for a snack to help bring your blood sugar up.

If symptoms occur regularly, it’s best to speak with your doctor. Left unchecked, out-of-whack glucose can spin into severe health issues like heart conditions or diabetic ketoacidosis, a dire emergency.

Speak with your doctor if:

• You're thirsty all the time
• You're getting sick often
• Your vision is blurry or your wounds are slow to heal.
• You’re urinating more than usual.
• You feel numbness and tingling in your hands and feet.
