The Role of Insulin and Glucagon

Maintaining normal blood glucose levels is crucial for overall health. Two key hormones produced by the pancreas play a central role in this regulation:

• Insulin: Produced by beta cells in the pancreas, insulin helps cells absorb glucose for energy and store excess glucose in the liver and muscles. It is released in response to elevated blood glucose levels, especially after eating.
• Glucagon: Produced by alpha cells in the pancreas, glucagon is released when blood glucose levels are low. It stimulates the liver to release stored glucose into the bloodstream and encourages the breakdown of fats for energy.

Abnormal Blood Glucose Levels

Abnormal blood glucose levels can have significant health impacts:

• Hypoglycemia: Occurs when blood glucose levels drop too low (generally below 70 mg/dL or 3.9 mmol/L). Symptoms include weakness, shakiness, and confusion. It’s important for individuals with diabetes to manage their medication and diet to prevent hypoglycemia.
• Hyperglycemia: Characterized by elevated blood glucose levels (typically 100 mg/dL or 5.6 mmol/L and above). Persistent high levels can be a sign of diabetes and may lead to complications. Symptoms include increased thirst, frequent urination, fatigue, and blurred vision.

When and How to Check Blood Glucose Levels

Monitoring blood glucose levels is essential for managing diabetes and assessing risk for developing diabetes. The frequency and timing of checks depend on the type of diabetes and individual health needs.

Type 1 Diabetes

• Frequency: Often requires multiple checks per day.
• Timing:
  • Before meals to determine pre-meal glucose levels.
  • After meals to evaluate the impact of food.
  • Before bedtime to ensure stability overnight.

Type 2 Diabetes

• Frequency: Varies; some may need daily checks while others monitor less frequently.
• Timing:
  • Fasting levels in the morning before breakfast.
  • Postprandial levels (2 hours after meals).
  • Periodic checks as advised by healthcare providers.

Gestational Diabetes

• Frequency: Regular monitoring is required.
• Timing: Typically, fasting levels in the morning and postprandial levels after meals.

At-Risk Individuals

• Frequency: Occasional checks may be beneficial for those at risk or with prediabetes.

Methods for Checking Blood Glucose

• Blood Glucose Meters: Requires a small blood sample from the fingertip, analyzed by a meter.
• Continuous Glucose Monitoring (CGM): Uses a sensor placed under the skin to provide real-time data on glucose levels.

Blood Glucose Levels: Low, Normal, and High

Blood glucose levels are measured in mg/dL or mmol/L. Here’s what these levels generally indicate:

Low Blood Glucose (Hypoglycemia)

• Fasting: Below 70 mg/dL (3.9 mmol/L).
• Postprandial: Levels below 70 mg/dL (3.9 mmol/L).

Normal Blood Glucose

• Fasting: Between 70-99 mg/dL (3.9-5.5 mmol/L).
• Postprandial: Less than 140 mg/dL (7.8 mmol/L) two hours after eating.

High Blood Glucose (Hyperglycemia)

• Fasting: 100 mg/dL (5.6 mmol/L) or above.
• Postprandial: Exceeding 180 mg/dL (10.0 mmol/L) two hours after eating.

Understanding Insulin and Glucagon

Insulin and glucagon are essential hormones for regulating blood glucose levels:

Insulin

• Production and Release: Produced by the pancreas and released after eating.
• Function: Helps cells absorb glucose for energy and stores excess glucose as glycogen. It also inhibits fat breakdown.

Glucagon

• Production and Release: Produced by the pancreas and released when blood glucose is low.
• Function: Raises blood glucose levels by stimulating glucose release from the liver and encouraging fat breakdown.

Together, insulin and glucagon maintain blood glucose homeostasis, ensuring energy supply is balanced with demand.

How the Blood Glucose Calculator Works

The Blood Glucose Calculator helps users quickly assess their glucose levels. Here’s how it works:

Input Parameters
