What Should Blood Sugar Be At Bedtime

Avoid Sweets Right Before Bed

Bedtime Snack For Gestational Diabetes (for good blood sugar levels)

We have discussed how insulin sensitivity decreases in the evening, as well as the potential reactive hypoglycemic effects of high sugar/starch foods. Avoiding sweets before bed can help circumvent both of those issues.

If you still find yourself craving something sweet, try switching to sources that include fiber or have a reduced sugar content . This can aid in smoothing out glucose levels.

What Should I Do If This Happens

People and their partners or roommates should learn to recognize the signs of nighttime hypoglycemia. Be prepared! Ask your doctor for an emergency glucagon kit. This kit contains a fast-acting medication that can be injected if the person cant be woken up. Store the kit in a bedside drawer for easy access.


  • If the person cannot be woken: If there is no emergency glucagon kit, call 911. If the person has a glucagon kit, the partner or roommate should follow the instructions to fill the syringe and inject the medicine. Once fully awake, he/she should eat a meal and check their blood glucose every few hours using a home test kit. After giving the injection, the persons doctor should be notified.

  • If the person can be woken up and sit without support: They should be given a fast-acting glucose source. Good options include hard candy, fruit juice or glucose paste or tablets, which can be purchased at most pharmacies. Once the person is fully awake, they should eat a meal and check their blood glucose every few hours using a home test kit.

How To Avoid Low Blood Sugar At Night

A good first step to try and prevent low blood glucose levels is to test your blood glucose levels before bed using your CGM or blood glucose meter. If you know your levels before going to bed you can easily adapt to them. This can help to prevent blood glucose levels drop significantly. Going to bed with stable blood sugars is highly recommended.

If you suspect hypoglycemic episodes overnight, conduct a blood sugar test at 3 am and compare it with your before bed and first thing in the morning tests. You can also adjust your insulin dose according to what you eat. Always consult your doctor before adjusting your insulin yourself.

Its important to have proper nutrition before hitting the hay. Prevent high blood sugar by taking some carbohydrates before bedtime, and prevent low blood sugar by eating a bit of protein.

What Happens To Blood Sugar While You Sleep

Itâs tied to whether the hormone insulin, which removes glucose from the blood, is working the way itâs supposed to. Blood sugar levels surge while youâre sleeping, usually around 4 to 8 a.m. for someone with a normal sleep schedule. In a healthy person, insulin can handle the surge by telling muscle, fat, and liver cells to absorb the glucose from the blood, which keeps your levels stable.

For people who have diabetes or who are likely to get it, insulin canât do that job very well, so blood sugar levels will rise higher.

Normal Blood Sugar Levels Chart

Maintaining normal blood sugar levels is essential to your mental and physical health.

The normal blood sugar levels chart below shows the range to shoot for and the diabetes blood sugar levels chart shows levels to avoid.

What is blood sugar? Its the glucose in your bloodstream that your body uses to produce energy. For most people, normal blood sugar levels range from 80 up to 140 naturally fluctuating throughout the day.

A healthy body has effective ways of regulating normal blood sugar levels.

For example, if your blood sugar falls too low, extra glucose stored in your liver is absorbed into your bloodstream to make up the difference.

Prepare Your Bedroom For Sleep

To optimize your ability to fall asleep and stay that way throughout the night, your room needs to be quiet, cool, dark, and comfortable.

Set the thermostat between 60F and 67F the optimal temperature for sleep.

Dim the lights. Close the shades and curtains so the rising sun wont wake you up in the morning.

Move your cellphone to another room or put it in a drawer so incoming texts and calls dont wake you up. If youre sensitive to noise, get a fan or white noise machine, or use earplugs to block out any unwanted sounds.

All of these things can prep the sleep hormones to kick in and help you fall asleep.

How Do Glucose Levels Change Overnight

A persons blood sugar levels change during the night, mainly, because of two processes:

A person can identify how their glucose levels change during the night by taking various readings.

  • The dawn phenomenon. Between roughly 3:00 a.m. and 8:00 a.m., blood sugar levels surge as part of the process of waking up. This causes high blood sugar levels in the morning.
  • The Somogyi effect. Glucose levels drop significantly between 2:00 a.m. and 3:00 a.m. The body responds by releasing hormones that raise blood sugar levels again. It can release too much of these hormones, leading to high blood sugar levels in the morning.

Eating a bedtime snack can prevent blood glucose levels from dropping very low during the night and lessen the Somogyi effect.

A person can determine how their glucose levels change throughout the night by taking readings at various points, such as just before bed, between 2:00 a.m. and 3:00 a.m., and again when waking up.

Understanding how the body is processing blood sugar is the first step toward picking more healthful snacks in the evening and before bed.

According to the American Diabetes Association , being overweight or having obesity increases the risk of diabetes-related complications. A variety of bedtime snacks can fit into a balanced, healthful diet.

What Causes Low Blood Sugar

Low blood sugar has many causes, including missing a meal, taking too much insulin, taking other diabetes medicines, exercising more than normal, and drinking alcohol. Blood sugar below 70 mg/dL is considered low.

Signs of low blood sugar are different for everyone. Common symptoms include:

  • Shaking.
  • Dizziness.
  • Hunger.

Know what your individual symptoms are so you can catch low blood sugar early and treat it. If you think you may have low blood sugar, check it even if you dont have symptoms. Low blood sugar can be dangerous and should be treated as soon as possible.

Know The Signs Of Low Overnight Blood Sugar

Symptoms of hypoglycemia usually develop when blood sugar levels drop below 70 milligrams per deciliter . They include shakiness, sweating, confusion, erratic behavior, headache, and lightheadedness. With nighttime hypoglycemia, you may wake up with these symptoms or with a higher blood sugar reading that results from the bodys response to an overnight low. However, some people experience whats referred to as hypoglycemia unawareness, which means that they dont feel the symptoms of low blood sugar.

Talk with your doctor about ways to recognize nighttime hypoglycemia, especially if you think you may have difficulty detecting it. Its a dangerous condition because people cant tell when their blood sugar has dropped, since they may not have symptoms, Dr. Rodbard says. The body can get desensitized to it. People with hypoglycemia unawareness are also less likely to wake up as a result of nighttime dips in their blood sugar.

Translating Your A1c To A Blood Sugar Level

Non Fasting Blood Sugar Levels Chart

Using this easy calculator from the ADA, you can translate your most recent A1C result to an eAG or estimate average glucose level.

You can also use this translation when working to improve your A1c and achieving closer to normal blood sugar levels. If you know an A1c of 6.5 is an average blood sugar level of 126 mg/dL or a range of 100 to 152 mg/dL, then you can look at your current blood sugar results on your CGM and meter and pinpoint which time of day youre frequently higher than this range.12% = 298 mg/dL or range of 240 347 11% = 269 mg/dL or range of 217 31410% = 240 mg/dL or range of 193 2829% = 212 mg/dL or range of 170 2498% = 183 mg/dL or range of 147 2177% = 154 mg/dL or range of 123 1856% = 126 mg/dL or range of 100 1525% = 97 mg/dL or range of 76 120

Normal blood sugar levels in a person without diabetes can result in an A1c as low as 4.6 or 4.7 percent and as high as 5.6 percent.

Just a decade or two ago, it was rare for a person with type 1 diabetes to achieve an A1c result below 6 percent. Thanks to new and improved insulin and better technology like continuous glucose monitors and smarter insulin pumps, more people with diabetes are able to safely achieve A1c levels in the higher 5 percent range.

Check Your Blood Sugar Before Bed

For everybody with type 1 or type 2 diabetes, its absolutely critical that they check their blood sugar before going to bed to make sure theyre not going to have an episode of low blood sugar during the night, says Helena W. Rodbard, MD, medical director of Endocrine and Metabolic Consultants, a private practice in Rockville, Maryland, and past president of the American College of Endocrinology.

If your blood sugar levels are low at bedtime, eat a healthy snack before going to sleep. The size of the snack should be in proportion to the dip in blood sugar. For instance, a small drop in blood sugar requires only a small snack. If you use an insulin pump, consider temporarily reducing the active dose of insulin.
