Low Blood Sugar (Hypoglycaemia) Treatment in Mumbai, India

Low blood sugar, medically known as hypoglycaemia, occurs when the amount of glucose in the bloodstream falls below what the body needs to function properly. Since glucose serves as a key source of energy, particularly for the brain, a significant drop can interfere with normal bodily functions and cause a variety of symptoms, ranging from mild weakness and dizziness to more serious complications.

Although hypoglycaemia is commonly linked to diabetes treatment, it can also develop in people without diabetes. Factors such as skipping meals, prolonged periods without food, excessive alcohol consumption, certain hormone-related disorders, and some medical conditions may contribute to low blood sugar levels.

Prompt recognition and treatment of hypoglycaemia are important to prevent complications and restore normal blood sugar levels.

Alternative Names

Hypoglycaemia may also be referred to as:

• Low blood sugar
• Low blood glucose

Types of Hypoglycaemia

Hypoglycaemia can occur in different situations depending on the underlying cause.

Reactive Hypoglycaemia

Reactive hypoglycaemia occurs within a few hours after eating. It may be related to an excessive release of insulin following a meal, causing blood sugar levels to fall.

Fasting Hypoglycaemia

Fasting hypoglycaemia develops when a person has not eaten for an extended period. It may be associated with certain medical conditions, medications, or hormonal imbalances.

Medication-Induced Hypoglycaemia

This type commonly affects people with diabetes who use insulin or certain glucose-lowering medications. Taking too much medication, missing meals, eating less than usual, or increased physical activity can trigger low blood sugar.

Nocturnal Hypoglycaemia

Nocturnal hypoglycaemia occurs during sleep and is commonly seen in individuals with diabetes. It may cause night sweats, restless sleep, nightmares, or waking up feeling tired and confused.

Symptoms of Hypoglycaemia

Symptoms can develop suddenly and may vary from person to person.

Common symptoms include:

• Shaking or trembling
• Sweating
• Hunger
• Dizziness
• Weakness or fatigue
• Headache
• Rapid heartbeat
• Irritability or mood changes
• Difficulty concentrating
• Blurred vision
• Anxiety or nervousness

Severe hypoglycaemia may cause:

• Confusion
• Slurred speech
• Loss of coordination
• Seizures
• Loss of consciousness

Causes of Hypoglycaemia

Hypoglycaemia can result from various factors that affect the body's ability to maintain normal blood glucose levels.

Common causes include:

• Taking too much insulin
• Use of certain diabetes medications
• Skipping or delaying meals
• Eating insufficient carbohydrates
• Intense or prolonged physical activity
• Excessive alcohol consumption
• Hormonal deficiencies
• Liver disease
• Kidney disease
• Certain pancreatic disorders

Diagnosis of Hypoglycaemia

Diagnosis begins with a detailed medical history, symptom assessment, and evaluation of blood glucose levels. In people with diabetes, hypoglycaemia is commonly considered when blood glucose falls below 70 mg/dL. In people without diabetes, doctors may also look for Whipple’s triad, which includes symptoms of hypoglycaemia, documented low blood glucose, and improvement of symptoms after glucose levels are corrected.

Common diagnostic methods include:

Blood Glucose Testing

A blood sugar test confirms whether glucose levels are low when symptoms.

Medical History and Physical Examination

The doctor will review medications, dietary habits, medical conditions, alcohol intake, physical activity, and symptom patterns.

Continuous Glucose Monitoring (CGM)

For some individuals, especially those with diabetes, continuous glucose monitoring may help identify recurring episodes of low blood sugar, including overnight episodes.

Additional Blood Tests

Further investigations may be required to identify hormonal disorders, liver disease, kidney disease, or other underlying causes contributing to hypoglycaemia.

Treatment for Hypoglycaemia

Treatment depends on the severity of symptoms and the underlying cause.

Immediate Treatment

Mild to moderate hypoglycaemia is often treated by quickly raising blood sugar levels. If the person is awake and able to swallow safely, fast-acting carbohydrates are usually recommended.

Common options include:

• Glucose tablets
• Fruit juice
• Regular soft drinks containing sugar
• Honey or sugar
• Hard sweets

A commonly used approach is to take about 15 grams of fast-acting carbohydrate, wait 15 minutes, and recheck blood sugar if testing is available. If blood sugar remains low or symptoms continue, the process may need to be repeated. After symptoms improve, a snack or meal containing carbohydrates and protein may help maintain stable blood sugar levels.

Management of Severe Hypoglycaemia

Severe hypoglycaemia requires urgent medical attention, especially if the person is confused, having seizures, unable to swallow safely, or unconscious. Food or drink should not be given by mouth to an unconscious person because of the risk of choking.

Treatment may involve:

• Glucagon injection or nasal glucagon, if available and prescribed
• Intravenous glucose administered in a healthcare setting
• Emergency medical care for unconscious individuals

Long-Term Management

Long-term treatment focuses on preventing future episodes and addressing the underlying cause.

This may include:

• Adjusting diabetes medications
• Reviewing insulin doses
• Meal planning and dietary modifications
• Monitoring blood sugar levels regularly
• Carrying fast-acting glucose
• Keeping glucagon available for those at risk of severe hypoglycaemia
• Managing associated medical conditions

Prevention of Hypoglycaemia

Preventive measures can significantly reduce the risk of low blood sugar episodes.

Helpful strategies include:

• Eating regular, balanced meals
• Avoiding skipped meals
• Monitoring blood glucose levels as advised
• Taking medications exactly as prescribed
• Carrying a quick source of glucose when travelling or exercising
• Planning meals around physical activity
• Limiting excessive alcohol intake
• Learning to recognise early warning signs

People with diabetes should work closely with their healthcare team to create an individualised prevention plan.

Risk Factors for Hypoglycaemia

Various factors can increase the chances of developing hypoglycaemia.

These include:

• Diabetes treated with insulin or certain oral medications
• Previous episodes of hypoglycaemia
• Irregular eating habits
• Intensive exercise programmes
• Older age
• Chronic kidney disease
• Liver disorders
• Hormonal deficiencies
• Excessive alcohol consumption

Understanding these risk factors can help individuals take appropriate precautions.

Complications of Hypoglycaemia

If not recognised and treated promptly, hypoglycaemia can lead to serious complications.

Potential complications include:

• Accidents and injuries due to dizziness or confusion
• Falls
• Seizures
• Loss of consciousness
• Cardiac rhythm disturbances
• Emergency hospitalisation
• Reduced quality of life due to fear of recurring episodes

Repeated severe episodes may affect daily functioning and require careful medical evaluation.
