How is Hypoglycaemia Diagnosed?
Doctors diagnose hypoglycaemia by checking blood glucose levels and confirming they are below normal. They will also inquire whether you experience symptoms related to the conditions. To confirm the diagnosis, doctors may track your blood sugar during a supervised 48-72-hour fast to identify periods of low glucose.
For reactive hypoglycaemia, a mixed-meal tolerance test (MMTT) may be performed, where blood sugar is checked several times after consuming a drink containing protein, fat and sugar. If another underlying cause of hypoglycaemia is suspected, additional imaging tests or blood tests (such as measuring insulin, C-peptide, or other hormone levels) may be required.
How is Hypoglycaemia Treated Based on Severity?
Hypoglycaemia treatment depends on the severity of low blood sugar and whether the person can safely consume fast-acting carbohydrates. Here is a summary of the treatment options based on how severe hypoglycaemia is:
| Clinical Severity | Treatment Approach |
| Mild (blood sugar |
Consuming 15 to 20 gms of fast-acting carbohydrates, like candy, honey, sugar, crackers, or glucose tablets or gels. |
| Moderate (low blood sugar despite taking fast-acting carbohydrates) | Consuming another 15 to 20 grams of fast-acting carbohydrates. Rechecking blood sugar levels and repeating the process if it's still low. |
| Severe (sugar levels below 55 mg/dL or patient unconscious or unable to eat/drink) | Emergency services required. An emergency glucagon injection, nasal spray or intravenous (IV) dextrose is used. |
Types of Hypoglycaemia and Their Treatment
The treatment for hypoglycaemia is often based on its type. Here are the types of hypoglycaemia and their treatment options:
| Type of Hypoglycaemia | Treatment Approach |
| Reactive Hypoglycaemia | Active dietary changes like avoiding processed food and small, frequent meals high in fiber/protein and low in simple sugars to prevent spikes and crashes. |
| Fasting Hypoglycaemia | Treated immediately by consuming fast-acting carbohydrates. Long term management requires treating underlying causes such as surgical removal of pancreatic insulinoma or treating organ failure. |
| Hormonal Hypoglycaemia | Short-term treatment includes eating fast-acting carbohydrates or glucagon injections. Long-term management requires dietary changes and hormone replacement therapy (such as hydrocortisone/corticosteroids) to address the underlying endocrine deficiency. |
| Nocturnal Hypoglycaemia | Treating low night-time blood sugar with simple sugars. Long-term management needs lifestyle changes such as adjusting bedtime insulin doses, enabling CGM alarms, and having a bedtime snack with complex carbohydrates and protein. |
| Diabetic Hypoglycaemia | Eating sugar or fast-acting carbohydrates to increase sugar levels for mild/moderate drops; using emergency glucagon for severe episodes. Adjusting diabetes medications and insulin intake to avoid sugar level drops. |
Medical Treatments for Hypoglycaemia
While the most commonly recommended treatment for hypoglycaemia is eating carbohydrates or sugary foods, the following treatment options are also used:
-
Glucose Tablets
These tablets contain pure glucose that can rapidly increase blood glucose levels. People with diabetes may frequently use these tablets during an episode of hypoglycaemia, with 15 grams of carbohydrates recommended. Blood sugar is typically rechecked after 15 to 20 minutes, and another dose may be taken if levels remain low (below 70 mg/dL).
-
Glucagon Injections
This is a hormone given as an emergency treatment that rapidly raises blood glucose by signalling the liver to release stored glucose. It can be life-saving when a person with hypoglycaemia is unconscious, having a seizure or unable to eat or drink. It is available as an emergency injection or as a nasal spray.
-
Octreotide Injection
This injection is a specialised, second-line therapy used in hospital settings for sulfonylurea-induced hypoglycaemia because it suppresses excessive insulin secretion from the pancreas. Its effect on blood glucose is temporary, so the person should eat as soon as possible to help replenish glycogen stores.
Note: You must follow the advice of a qualified medical care provider during the treatment for hypoglycaemia.
Ayurvedic and Alternative Treatments for Hypoglycaemia
Hypoglycaemia is a medical emergency and can only be treated with immediate and fact-acting glucose. You can use the following Ayurvedic and complementary medicines to support the medical treatment of hypoglycaemia:
-
Ayurvedic Medicines: Ayurvedic herbal remedies such as Shatavari and Ashwagandha capsules are used as supportive hypoglycaemia treatment along with fast-acting glucose, as they can help in keeping blood sugar levels at a healthy level.
-
Homeopathic Medicines: Homeopathic remedies used for hypoglycaemia include Arsenicum Album, Lycopodium, Carbo Veg, Calcaria Phos, Gelsemium, China, Natrum Mur, Sepia, Chelidonium and Nux Vomica.
-
Detoxification Therapies: Ayurvedic detoxification treatments such as Virechana (purgation) and Basti (medicated enemas) can be used as supplementary therapies for hypoglycaemia. These treatments can help eliminate toxins, known as Ama, rebalance the doshas and support metabolic function.
Note: Alternative treatments for hypoglycaemia should be undertaken after consulting a qualified practitioner.
Home Care for Managing Hypoglycaemia
The simple measures given below can help in managing hypoglycaemia at home:
-
Keep glucose tablets, sugary snacks and other carbohydrate-rich foods easily accessible in different areas of your home.
-
Let family members or people living with you know about your hypoglycaemia and explain what they should do if your blood sugar suddenly drops.
-
Monitor your blood sugar regularly at home using a glucometer.
-
If you have diabetes, follow the treatment plan recommended by your diabetes care team, including adjusting your insulin dose when required.
-
Carry a glucagon injection kit and medical identification with you, especially when going outside.
-
Keep an easy-to-carry source of sugar, such as glucose tablets, sweets or a sugary drink, with you when you leave home.
-
Avoid going without food for long periods and have meals or snacks at regular intervals.
-
Avoid strenuous exercise when you have not eaten enough carbohydrates beforehand.
How Long Does Hypoglycaemia Treatment Take?
Hypoglycaemia requires treatments that act rapidly and increase the sugar levels within a few minutes. Here are the approximate durations of each treatment:
| Treatment | Duration |
| Eating Fast-Acting Carbohydrates | Blood sugar levels increase within 5 to 15 minutes. |
| Glucagon Injections | Blood sugar levels increase within 15 to 20 minutes. |
| Octreotide Injection | A dose is given 3 times in one day. Duration differs as per doctor's recommendations. |
Hypoglycaemia Treatment Side Effects
Treatment options like glucagon injections and octreotide injections can have the following side effects on hypoglycaemia patients:
-
Glucagon Injection Side Effects
- Nausea and vomiting
- Transient increase in heart rate (tachycardia) and blood pressure

Hypoglycaemia Treatment Cost
The cost of treating hypoglycaemia depends on how severe the symptoms are and what line of treatment is recommended. Emergency glucagon injections cost around ₹900-₹1,000 per shot in India, though the cost may differ for each brand. If hospitalisation is required to treat the condition, the cost may range from ₹2,550 to ₹1.3 lakh, depending on the duration and type of treatment. A fasting blood sugar (FBS) test, which checks your blood sugar levels, can cost between ₹80 to ₹200.
Does Health Insurance Cover Hypoglycaemia Treatment in India?
When hypoglycemia is caused by a covered pre-existing condition like Diabetes Mellitus, its treatment is typically covered by health insurance. A waiting period of up to 3 years might apply before you file a claim settlement.
Coverage can include emergency hospitalisation for severe hypoglycaemia such as room rent, nursing charges, and ambulance services, as per the applicable limits. Some plans may also offer OPD coverage through add-on covers.
If hypoglycaemia is caused by a pre-existing condition such as diabetes mellitus, coverage is subject to the policy’s pre-existing disease waiting period, which can be up to 36 months.
While hypoglycaemia itself is not covered under critical illness insurance plans, its severe complications like cardiac arrest or coma, may be covered under such plans. These plans offer a lump sum compensation for treatment expenses. However, coverage is subject to a waiting period of up to 90 days and a survival period of up to 30 days.
If adequate financial protection for hypoglycaemia-related hospitalisation is required, a sum insured of ₹10 to ₹15 lakh is recommended.
Disclaimer: Review the policy documents carefully to learn the exact coverage offered, as the inclusions, exclusions, and waiting periods can differ.
