Hypoglycaemia (Low Blood Sugar) Guide 

Hypoglycaemia (Low Blood Sugar) Comprehensive Guide 

What is Hypoglycaemia?

Hypoglycaemia occurs when the blood sugar level drops below 70 mg/dL, leading to symptoms like dizziness, confusion, and in severe cases, unconsciousness. It is commonly seen in individuals with diabetes who take insulin or other blood-sugar-lowering medications, but it can also occur in non-diabetics due to other conditions.

Classifying Hypoglycaemia

Hypoglycaemia is classified as a metabolic condition that results in abnormally low blood sugar levels. It is often a sign of a broader problem, such as diabetes, pancreatic disorders, or hormone imbalances.

Types of Hypoglycaemia

1. Fasting Hypoglycaemia: Occurs after prolonged periods without eating.
2. Reactive Hypoglycaemia: Happens within a few hours after eating.
3. Drug-Induced Hypoglycaemia: Triggered by medications, especially insulin or diabetes drugs.
4. Non-Diabetic Hypoglycaemia: Can occur due to hormonal imbalances, alcohol, or critical illness.

Hypoglycaemia Health Signs and Symptoms

• Shaking or trembling
• Sweating
• Hunger
• Palpitations (rapid heartbeat)
• Dizziness or lightheadedness
• Confusion or difficulty concentrating
• Blurred vision
• Fatigue
• Seizures or loss of consciousness in severe cases

Hypoglycaemia Causes

• Diabetes medications: Especially insulin or sulfonylureas.
• Skipping meals: Not eating enough or fasting for long periods.
• Intense physical activity: Exercise can lower blood sugar, especially without proper fuel.
• Alcohol consumption: Alcohol interferes with the liver’s ability to release stored glucose into the bloodstream.
• Hormonal imbalances: Conditions like adrenal insufficiency or low levels of growth hormone.

Hypoglycaemia Stages

1. Mild: Early signs like shaking, sweating, and hunger.
2. Moderate: Progresses to confusion and difficulty thinking clearly.
3. Severe: Loss of consciousness or seizures requiring emergency intervention.

How to Prevent Hypoglycaemia

• Regular meals and snacks: Avoid skipping meals, and include healthy carbs, proteins, and fats.
• Monitor blood sugar: Check blood sugar levels before and after meals, exercise, and insulin use.
• Adjust medications: Work with your healthcare provider to fine-tune your insulin or diabetes medications.
• Limit alcohol: Consume alcohol in moderation and never on an empty stomach.
• Be prepared: Always carry quick sources of sugar (glucose tablets or juice) for emergencies.

Hypoglycaemia Diagnosis

• Blood Glucose Test: A finger prick test using a glucometer can measure current blood glucose levels.
• Continuous Glucose Monitoring (CGM): Provides ongoing monitoring and alerts for low blood sugar episodes.
• Oral Glucose Tolerance Test (OGTT): Measures the body’s response to sugar after eating.

How to Test for Hypoglycaemia

1. Blood Glucose Meter: A portable device used to check blood sugar levels.
2. Continuous Glucose Monitor (CGM): Tracks glucose levels continuously, providing alerts for hypoglycaemia.
3. Oral Glucose Tolerance Test (OGTT): Used to diagnose reactive hypoglycaemia.

What Type of Health Professionals Treat Hypoglycaemia?

• Endocrinologists: Specialists in hormone-related conditions, including diabetes and hypoglycaemia.
• Primary Care Physicians: Handle initial diagnosis and management.
• Diabetes Educators: Provide education on managing blood sugar and lifestyle adjustments.
• Dietitians/Nutritionists: Offer guidance on meal planning to prevent low blood sugar.

Reasons to See a Hypoglycaemia Health Professional

• Frequent or unexplained low blood sugar episodes.

Process to Find the Right Hypoglycaemia Professional

• Referrals from Primary Care Doctor: Seek a referral for a specialist, such as an endocrinologist.
• Online Directories: Use reputable health platforms to find diabetes or hormone specialists.
• Consultation: Ensure the specialist has experience treating hypoglycaemia, particularly related to diabetes or metabolic disorders.

How to Prepare to See a Health Specialist?

• Keep a blood sugar log with details of readings, symptoms, and dietary intake.
• List all current medications and supplements.
• Prepare to discuss medical history and family history of metabolic disorders.
• Write down questions you want to ask during the appointment.
