Sleep plays a crucial role in maintaining healthy blood sugar levels. Blood sugar levels naturally fluctuate during sleep, and these fluctuations are typically harmless for most people. However, for individuals with diabetes, these fluctuations can be more extreme, leading to a condition called nocturnal hypoglycemia, where blood sugar levels drop below 70 mg/dL during sleep. Nocturnal hypoglycemia can cause disruptions in sleep patterns, headaches, and potentially dangerous consequences if left untreated. To prevent nocturnal hypoglycemia, individuals with diabetes should monitor their glucose levels before bed, consume a small snack if necessary, and discuss suitable insulin dosages with their healthcare provider. Continuous glucose monitors can also help track and manage blood sugar levels during sleep.

Nocturnal Hypoglycaemia
To prevent nocturnal hypoglycaemia, people with diabetes should ensure their glucose levels are above a suitable range before bed. This can be achieved by consuming a small, balanced snack before bed, such as a small piece of fruit and nuts or a slice of whole-grain bread with peanut butter. It is also recommended to use a continuous glucose monitoring (CGM) system to track glucose levels. These devices send audio and vibration alerts that wake the user if their blood sugar is dropping, allowing them to take corrective action. Additionally, individuals can work closely with their healthcare professionals to adjust insulin dosages and medication timings to minimise the risk of nocturnal hypoglycaemia.
Acting fast after an episode of nocturnal hypoglycaemia is critical. It is important to recognise the signs and symptoms of nocturnal hypoglycaemia to enable prompt action. Common symptoms include sweating and waking up with damp clothes or sheets. Doctors are most concerned about people who sleep through these symptoms without noticing them, as it can lead to prolonged and potentially severe hypoglycaemia. Therefore, it is crucial for individuals with diabetes and their caregivers to be educated about the condition and take preventive measures to ensure a safe and healthy night's sleep.

Risk Factors
Nocturnal hypoglycemia, or night-time hypos, refers to periods of low blood sugar levels during the night, typically while a person is sleeping. Nocturnal hypoglycemia can occur in people with diabetes due to the complex interplay of insulin, diet, physical activity, and sleep. It can also be caused by taking too much basal (background) insulin or consuming alcohol in the evening. If you are not diabetic, nocturnal hypoglycemia may be caused by compression hypoglycemia, which occurs when a continuous glucose monitor (CGM) is "compressed" due to laying on the sensor during sleep, resulting in a false low reading.
People with diabetes who use insulin should be aware of the risk of nocturnal hypoglycemia, especially if they have had an active day or exercised close to bedtime. Eating a late dinner and going to sleep a few hours later can also contribute to nocturnal hypoglycemia, as the insulin taken for dinner may still be working in the body, causing glucose levels to drop during the night.
Studies suggest that almost half of all episodes of low blood glucose and more than half of all severe episodes occur at night during sleep. Nocturnal hypoglycemia can be dangerous, especially if the person sleeping does not wake up to treat the condition. It is recommended that people with diabetes check their glucose levels before bed and consult with their healthcare team about suitable blood sugar targets and bedtime snacks to prevent nocturnal hypoglycemia.
In addition to diabetes management, maintaining healthy sleep habits is important in regulating blood sugar levels. Sleep loss and inadequate sleep are associated with increased glucose levels and a reduced ability to control glucose levels, respectively. Therefore, addressing sleep issues and obtaining restorative sleep may help lower unhealthy blood sugar levels.

Prevention Methods
Nocturnal hypoglycemia, or low blood sugar during sleep, is a potentially dangerous condition that can be prevented with careful planning. It is essential to consult a healthcare professional for personalized advice and to adjust your diabetes management plan if you experience frequent hypoglycemia. Here are some general prevention methods to avoid low blood sugar while sleeping:
- Monitor Blood Sugar Levels: It is important to regularly monitor your blood sugar levels, especially before going to bed. Work with your healthcare provider to determine suitable blood sugar targets before sleep and adjust your diabetes management plan accordingly.
- Use Continuous Glucose Monitors (CGM): Consider using a CGM system that can track your glucose levels throughout the night. These devices can check your blood glucose levels every few minutes and wake you up with an alarm if your levels start to drop too low.
- Adjust Insulin Dosage and Timing: Consult your doctor about adjusting the dosage and timing of your insulin or other medications. They may recommend taking a type of insulin called NPH at dinner, which becomes most effective six to eight hours after each dose.
- Consume Balanced Snacks Before Bed: Discuss with your healthcare team whether consuming a small, balanced snack before bed is appropriate for you. Suitable snacks may include a small piece of fruit and nuts or a slice of whole-grain bread with peanut butter.
- Avoid Evening Alcohol Consumption: Alcohol consumption in the evening can put you at risk for lower glucose levels during sleep. While your liver is busy clearing the alcohol from your blood, it may temporarily stop producing glucose.
- Schedule Physical Activity Earlier: Try to schedule physical activity earlier in the day, as exercising close to bedtime can lower glucose levels and increase the risk of nocturnal hypoglycemia.
- Recognize the Signs: Learn to recognize the signs and symptoms of nighttime hypoglycemia, such as restless sleep, sweating, crying out during sleep, nightmares, and feeling tired or disoriented upon waking up. Educate your roommates or partners about these symptoms so they can help identify and treat the condition.

Symptoms
Nocturnal hypoglycemia occurs when blood sugar levels drop below suitable ranges during sleep. This condition can be potentially dangerous, especially if the individual cannot wake up to treat their nighttime hypo. For people with diabetes, the complex interplay of insulin, diet, physical activity, and sleep can lead to extreme fluctuations, resulting in hypoglycemia.
Some common symptoms of nocturnal hypoglycemia include:
- Sweating and waking up with damp clothes or sheets
- Shaking
- Dizziness
- Headaches
- Disrupted sleep patterns
If you are experiencing nocturnal hypoglycemia, it is recommended to consult a doctor. Doctors are particularly concerned about people who sleep through these symptoms without noticing them. It is important for individuals and their partners or roommates to learn to recognize the signs of nighttime hypoglycemia and take preventive measures.
To minimize the risk of nocturnal hypoglycemia, individuals can ensure their glucose levels are within a suitable range before bed. This can be achieved by using continuous glucose monitors, checking glucose levels before bed, consuming a small balanced snack before bed, adjusting insulin dosages or medication, and avoiding physical activity close to bedtime.

Treatment
Nocturnal hypoglycemia, or low blood sugar during sleep, can be potentially dangerous. However, with careful planning and management, the risks can be minimised.
If you are experiencing nocturnal hypoglycemia, it is important to consult a doctor, who may recommend a continuous glucose monitor (CGM) to track your glucose levels. CGMs can be programmed to alert you to low blood sugar levels, and wake you up if they drop too low. This can be especially useful during sleep, when it may take longer to notice symptoms and wake up.
If you have diabetes, you should ensure your blood sugar levels are in a suitable range before going to bed. This may involve adjusting your insulin dosage or medication, in consultation with your doctor. You may also want to consider having a small, balanced snack before bed, such as a small piece of fruit and some nuts, or a slice of wholegrain bread with peanut butter.
If you are experiencing frequent nocturnal hypoglycemia, you should work with your healthcare provider to adjust your diabetes management plan. They may recommend additional tests to determine the underlying cause, such as imaging tests to check for a tumour, or a mixed-meal tolerance test (MMTT).
