Low blood sugar at night, also called nocturnal hypoglycemia, can affect many people, especially those with diabetes. When your blood sugar drops too low while you’re sleeping, it can cause different symptoms that might wake you up or go unnoticed until morning. It’s really important to know these signs because untreated low blood sugar can lead to serious problems. Read on to learn five common symptoms of low blood sugar at night so you know what to look out for and what to do.

1. Waking Up Covered In Sweat

One of the most common signs of low blood sugar at night is waking up covered in sweat. Night sweats happen because your body is under stress from low blood sugar. When your glucose levels drop, your body releases hormones like adrenaline to bring them back up, which often causes heavy sweating. If you often wake up with your clothes or sheets soaked, it might mean your blood sugar is dropping too low while you sleep.

2. Having Nightmares Or Very Vivid Dreams

Low blood sugar can also cause nightmares or vivid dreams. When your brain isn’t getting enough sugar, it can become overactive, which might lead to scary dreams or even night terrors. If you notice that you often have bad dreams, especially if you have diabetes, it could be because of low blood sugar at night.

3. Feeling Very Tired Or Confused In The Morning

If your blood sugar drops during the night, you might not wake up right away, but you could feel the effects in the morning. Feeling very tired, groggy, or confused could be a sign that your blood sugar was low while you were sleeping. You might find it hard to get out of bed or feel like you didn’t sleep well. This is because your body and brain were working hard to fix the low blood sugar, which can leave you feeling worn out.

4. Waking Up With A Headache

Another common sign of low blood sugar at night is waking up with a headache. When your brain doesn’t get enough energy during a low blood sugar episode, it can lead to a headache. These headaches can be mild or really painful. The combination of hormone changes and poor sleep can also make headaches worse. If you often wake up with headaches, it might be worth checking your blood sugar levels to see if low blood sugar at night is the cause.

5. Fast Heartbeat Or Shaking

A fast heartbeat or shaking can also happen when your blood sugar drops too low at night. These symptoms are part of your body’s response to low glucose, as adrenaline is released to help bring your blood sugar back to a safe level. You may wake up feeling your heart racing or notice that your hands are shaking. These signs can be scary and are a clear signal that your body is struggling to keep your blood sugar balanced.

How To Prevent Low Blood Sugar At Night

If you have symptoms of low blood sugar at night, it’s important to talk to your doctor. They might suggest changing your medication, diet, or what you eat before bed to help keep your blood sugar stable overnight. Eating a balanced snack before bed, like a small amount of protein and complex carbohydrates, can help keep your glucose levels steady while you sleep. Also, regularly checking your blood sugar and knowing the early signs of hypoglycemia can help you take steps to stop nighttime lows.

When To Talk To A Doctor

If you often have symptoms of low blood sugar at night, talk to your doctor. Regular low blood sugar during the night can raise the risk of more serious hypoglycemia, which can be dangerous if not treated. Your doctor may suggest changes to your diabetes care plan, like adjusting your insulin dose or changing your diet, to help prevent these episodes.
