Hypoglycaemia (low blood sugar) Treatment
Last Updated: July 3, 2026
Lifestyle Modifications
Prevent and effectively manage hypoglycaemic episodes through proactive self-care and informed decision-making.
- Adhere strictly to your prescribed diabetes treatment plan, including careful adjustment of insulin doses or other medications as advised by your care team.
- Monitor your blood sugar regularly, especially before and after meals, exercise, and at bedtime, to promptly detect and address any fluctuations.
- Always carry fast-acting carbohydrates, such as glucose tablets, sugary drinks, or sweets, for immediate self-treatment of mild to moderate hypoglycaemia.
- Educate family members, friends, and colleagues on how to recognize the symptoms of hypoglycaemia and how to assist in severe cases, including administering a glucagon injection if necessary.
- Maintain consistent meal schedules, avoiding skipped or delayed meals, and ensure adequate carbohydrate intake to match your medication and activity levels.
- Moderate alcohol consumption; avoid drinking alcohol without eating, and adhere to recommended guidelines (e.g., no more than 14 units per week spread over 3+ days).
- If you drive, check your blood sugar before each journey and every two hours during driving. Do not drive for at least 45 minutes after your blood sugar returns to normal following a hypo.

Medicinal Treatment
Rapidly restore blood glucose levels to a safe range and implement strategies to prevent future occurrences.
- Immediate intake of quick-acting carbohydrates (e.g., 15-20g of glucose from fruit juice, sugary fizzy drinks, glucose tablets, or glucose gel) to rapidly raise blood sugar levels.
- Administration of a glucagon injection for severe hypoglycaemia, particularly if the individual is unconscious or unable to swallow safely, as per medical instruction.
- Adjustment of insulin doses or other diabetes medications (e.g., sulfonylureas) under the guidance of a healthcare professional to prevent recurrent episodes of low blood sugar.
- Utilization of Continuous Glucose Monitors (CGMs) or flash monitors to provide real-time blood sugar data, enabling proactive management and early detection of impending hypos.
- Consultation with a diabetes care team for persistent or nocturnal hypoglycaemia, or if there is impaired awareness of hypoglycaemia symptoms.

Surgical Treatment
Address rare underlying causes of recurrent hypoglycaemia that are not manageable through medical or lifestyle interventions.
- Surgical intervention is generally not a direct treatment for acute hypoglycaemia itself, which is managed through immediate carbohydrate intake or glucagon administration.
- In rare instances, if recurrent and severe hypoglycaemia is caused by an underlying condition such as an insulinoma (a tumor in the pancreas that overproduces insulin), surgical removal of the tumor may be considered.
- This surgical approach targets the root cause of excessive insulin secretion to prevent future severe episodes, rather than treating the symptomatic low blood sugar directly.
