Living with diabetes brings its own set of hurdles, and one such challenge is the presence of hypoglycemia, commonly known as low sugar. Whether you have Type 1 or Type 2 diabetes, managing your blood sugar levels becomes a delicate balancing act.

The fear and anxiety accompanying hypoglycemia episodes can hinder your ability to achieve optimal control and reach your health goals. 


However, with the right knowledge and strategies, you can take charge and prevent these low-sugar episodes from disrupting your daily life. 

In this article, we will dig into the depths of diabetes and hypoglycemia, equipping you with the tools and understanding to overcome this obstacle, embrace low sugar, and empower you to live life to the fullest.

What exactly is hypoglycemia or low sugar? 

Hypoglycemia, also known as low sugar, is a common symptom experienced by people with diabetes, regardless of whether they have Type 1 or Type 2 diabetes mellitus. It occurs when the glucose concentration in the blood drops below 70mg/dl, which can potentially harm the patients. 

Severe low blood sugar is when it goes below 54 mg/dl; at this point, the individual may require assistance to treat the episode.

It can also occur when taking oral medications or insulin injections as part of their treatment.

Apart from that, the episodes of hypoglycemia bring physical and psychological challenges like fear and anxiety. This fear becomes a barrier, making it hard for patients to control their blood sugar levels and reach their goals.

Lack of awareness, called hypoglycemia unawareness, can be dangerous and reduce the quality of life. So, educating patients is key to prevention.

What are the signs and symptoms of hypoglycemia?


The signs and symptoms of hypoglycemia can vary among patients, depending on their age, duration of diabetes and severity of hypoglycemia.

For example, children may experience emotional and behavioural changes alongside classic autonomic and neuroglycopenic symptoms.

  • Autonomic symptoms related to the involvement of the autonomic nervous system include anxiety, trembling, palpitations, sweating, and feeling hungry.
  • Neuroglycopenic symptoms, caused by the brain’s glucose deprivation, include lack of concentration, headaches, blurred vision, dizziness, confusion, convulsions, speech difficulties, restlessness, and even loss of consciousness.

**Such hypoglycemia signs and symptoms are usually observed when blood sugar levels drop around 54 mg/dL.

What are the risk factors for hypoglycemia?

Several risk factors contribute to the occurrence of hypoglycemia. These include:

  1. Taking high doses of insulin or oral drugs like sulfonylureas or glinides, especially if not timed correctly with meals.
  2. Consuming very low-carbohydrate meals or fasting for long periods can limit the body’s ability to produce glucose.
  3. Experiencing hypoglycemia after engaging in heavy physical exercise.
  4. Experiencing a decrease in insulin excretion due to conditions like kidney failure, liver failure, or thyroid problems.

What are the effects of hypoglycemia?

Hypoglycemia can cause both physical and psychological issues for diabetic patients. It can impair judgment, affect daily activities such as driving, learning, concentration and impact behaviour.

It may lead to convulsions, loss of consciousness, and even transient neurological deficits or stroke in severe cases. Repeated episodes of hypoglycemia can result in a lack of warning symptoms, referred to as Hypoglycemia unawareness.

What is the treatment of hypoglycemia?

There is a practical approach known as the “Rule of 15” that can help manage low blood sugar (hypoglycemia) effectively. Here’s how it works:


The Rule of 15:

1. Check your blood sugar levels using a glucometer to ensure they are below 70 mg/dL, indicating hypoglycemia.  

2. Now, consume 15 grams of carbohydrates to increase blood sugar levels. E.g., 15 grams of glucose powder, 3 glucose biscuits, 3 hard candies, 150 ml of fruit juice (without added sugars) etc.

3. Wait for 15 minutes to allow the carbohydrates to be absorbed and raise your blood sugar levels.

4. After 15 minutes, recheck your blood sugar levels to assess if they have risen above 90 mg/dL (this is the target range to aim for).

**Repeat if necessary: If your blood sugar is still below 90 mg/dL, repeat the initial step, and wait for another 15 minutes

5. Once your blood sugar rises above 90 mg/dL, consuming a balanced meal or snack is essential to provide sustained energy and prevent a subsequent drop in blood sugar levels.

Remember, the Rule of 15 is a guideline for managing low blood sugar levels, and it’s essential to consult with healthcare professionals for personalised advice on managing diabetes and hypoglycemia.

How to prevent hypoglycemia?

1) Patient Education: Know the Signs and Take Action

  • Make sure you and those around you can spot the symptoms of hypoglycemia.
  • Discuss the risks and treatment options with your healthcare provider.
  • Identify potential triggers, like missed meals, intense exercise, or alcohol consumption.
  • Carry glucose or carb-rich snacks to tackle low blood sugar on the go.

2) Smart Eating: Balance Carbohydrates for Blood Sugar Control

  • Understand the impact of carbohydrates on blood glucose levels.
  • Create a personalised meal plan with a focus on insulin timing and dosage.
  • Always keep glucose or carb-containing foods readily available.
  • Consider a bedtime snack to prevent nighttime hypoglycemia, especially for type 1 diabetes.

3) Exercise with Caution: Manage Blood Sugar during Physical Activity

  • Monitor your blood sugar levels before and after workouts.
  • Take precautions to prevent hypoglycemia, such as eating small meals beforehand.
  • Carry fast-acting carbs or glucose during exercise sessions.
  • Adjust insulin doses based on your planned physical activity.

4) Stay on Top with Glucose Monitoring: Catch Hypoglycemia Early

  • Regularly check your blood glucose levels using self-monitoring.
  • Test before meals, after meals occasionally, before sleep or at 3 am, before demanding tasks like driving, after treating hypoglycemia, and when suspecting low blood sugar.
  • Consider continuous glucose monitoring (CGM) for real-time glucose measurement.

5) Medication Adjustment: Minimize Hypoglycemia Risk

  • Once diagnosed with diabetes, talk to your doctor and maintain proper follow-ups.
  • Avoid self-medications or dose modification.
  • Use home remedies with caution.
  • Discuss alternate options for insulin and its analogues to reduce hypoglycemia.
  • Evaluate the need to reduce or discontinue medications.

By following these practical strategies, you can actively prevent hypoglycemia and maintain stable blood sugar levels. Remember, staying informed and taking proactive steps are key to achieving your diabetes management goals.


Understanding hypoglycemia is vital for effective diabetes management. It’s as important as achieving blood sugar control and hitting target levels. However, at some point, nearly every person with diabetes encounters hypoglycemia. 

But that can be manageable if you follow prevention strategies such as smart eating habits, careful exercise management, regular glucose monitoring, and medication adjustment. You can actively prevent hypoglycemia and maintain stable blood sugar levels.
