Why Does Blood Sugar Go Up At Night
There are many factors that can cause your blood sugar to increase at night. For example: what food you ate during the day, how much and when you exercised, whether you ate snacks before bed, the timing of your insulin doses, and your stress level. You can experience different patterns of high blood sugar at night. You may start with high glucose when you go to bed, start the night in range but go high several hours later, or spend most of the night in range until the hours just before you wake up. By identifying your bodys patterns, you can figure out what is causing your high blood sugar and how to address it.
Common causes of a glucose increase at night include:

How Do You Treat Hypoglycemia
Low blood sugar levels happen when theres too little glucose left in the bloodstream to continue supplying fuel to your organs, muscles, and tissues. It most often occurs when you dont eat enough food, especially carb-containing foods, given your blood-sugar-lowering medications and physical activity levels, ONeill says. Levels can decrease gradually or suddenly.
When the amount of glucose in the bloodstream drops to too-low levels, the body reacts by releasing epinephrine, also called adrenaline or the fight or flight hormone. Epinephrine revs your heart rate and can cause sweating, shaking, anxiety, and irritability. If not enough glucose is able to reach the brain, the result may be difficulty concentrating, confused thinking, and slurred speech. In extreme cases, a lack of glucose within the brain can lead to seizures, coma, and even death, she says.
People with low glucose levels can use the ADAs 15-15 Rule, which advises people consume 15 g of carbs, wait 15 minutes, and check their levels again. If the number is still low, repeat until reaching at least 70 mg/dL.
You can find 15 g of carbs in:
- 1 slice of bread
- 1 small piece of fresh fruit
- cup of yogurt
- Three to four hard candies
- Glucose tablets as indicated on the label
- Glucose gel as indicated on the label
Once your glucose levels are back to normal, the ADA suggests going ahead and eating your next scheduled meal or snack, which will help prevent levels from dropping again.
Symptoms Of High Blood Sugar
Depending on the cause of your high blood sugars, the symptoms could develop quickly or gradually.;
People with undiagnosed type 1 diabetes will develop nearly all of the symptoms of high blood sugar very quickly, over the course of a few weeks, because their blood sugar levels are rising rapidly while insulin production is declining rapidly.
People with prediabetes or type 2 diabetes may not notice these symptoms for months or years because gradually increasing insulin resistance and beta-cell dysfunction can take a long time to become severe enough to produce noticeable symptoms.
Visit your local emergency room immediately if you are experiencing any of these severe symptoms.
What Is The A1c Blood Test
The A1 blood test is a test to measure your average blood sugar level over the past three months. The AIC test is also called a hemoglobin test or glycosylated hemoglobin . This type of diabetes test checks for high levels of glucose in the blood, which can cause many problems if left untreated.
If you’ve been diagnosed with diabetes, it’s important to know what your A1C level is. The American Diabetes Association recommends that the goal for people with diabetes should be less than 7%. This can not only help prevent cardiovascular disease and kidney problems but also have huge effects on preventing blindness and nerve damage. Even if you don’t have any of those symptoms yet, a regulated blood sugar level will decrease your risk over time.
The benefits of this diabetes testing include being able to detect diabetic symptoms before they arise with routine screening or prevent diabetes complications when you already have diabetes. If you have started showing signs that suggest an increase in A1C, then it may be time to see your doctor about possible treatment options including medication changes, exercise programs, and meal plans.
Great Bedtime Snacks For People Living With Diabetes
For some people, a healthy bedtime snack helps to prevent glucose swings during the night. By eating a small snack that is full of protein and healthy fats , your body may be better able to avoid an overnight high but if you take insulin, be sure to cover the carbohydrates in your snack even if it only requires a small dose of insulin.
Here are some snack ideas:;;
Plain nuts or seeds try eating a small handful
Raw vegetables, such as carrots, celery, cucumbers, or tomatoes, with a small amount of hummus or peanut butter
Plain yogurt, and you can add berries or cinnamon
Remember, a bedtime snack is only helpful for some people. To see if it works for you, youll have to carefully monitor your glucose before bed, during the night, and when you wake up.

What Should I Do If My Blood Sugar Gets Too High
High blood sugar is also called hyperglycemia . It means that your blood sugar level is higher than your target level or over 180. Having high blood sugar levels over time can lead to long-term, serious health problems.
If you feel very tired, thirsty, have blurry vision, or need to pee more often, your blood sugar may be high.
Check your blood sugar and see if it is above your target level or over 180. If it is too high, one way to lower it is to drink a large glass of water and exercise by taking a brisk walk. Call your health care team if your blood sugar is high more than 3 times in 2 weeks and you dont know why.
What Should My Blood Sugar Level Be
When you’re first diagnosed with diabetes, your diabetes care team;will usually tell you what your blood;sugar level is and what you should aim to get it down to.
You may be advised to use a testing device to monitor your blood sugar level regularly at home.
Or you may have an appointment with a nurse or doctor every few months to see what your average blood sugar level is. This is known as your;HbA1c level.
Target blood;sugar levels differ for everyone, but generally speaking:
- if you monitor yourself at home with a self-testing kit; a normal target is 4 to 7mmol/l before eating and under 8.5 to 9mmol/l 2 hours after a meal
- if your;HbA1c level is;tested every few months; a normal HbA1c target is below 48mmol/mol

What Are The Signs & Symptoms Of High Blood Sugar Levels
Signs of high blood sugar levels include:
- Peeing a lot: The kidneys respond by flushing out the extra glucose in urine. People with high blood sugar need to pee more often and in larger amounts.
- Drinking a lot: Someone losing so much fluid from peeing that often can get very thirsty.
- Losing weight even though your appetite has stayed the same: If there isn’t enough insulin to help the body use glucose, the body breaks down muscle and stored fat instead in an attempt to provide fuel to hungry cells.
- Feeling tired: Because the body can’t use glucose for energy properly, a person may feel unusually tired.
Think About What’s Going On
Irene Dunbar, 73, of Durham, N.C., woke up one morning recently to discover her blood sugar was at 119, which is high for her. “I had a cold and had had orange juice yesterday and I normally do not drink orange juice and I thought, ‘I better not do that,'” she said. When she gets a high blood sugar reading, she tries to remember if she had anything recentlylike breadthat she knows are triggers, and avoids them next time.

Reflect On The Amount Of Sugar In Your Diet
Hyperglycemia occurs when there is too much glucose in the blood.
Therefore, one way of reducing your blood glucose levels is reflecting on where sugar may be consumed in the diet. Think about any refined and processed foods that may be in your diet as these are often high in sugar. This can be achieved through a low carbohydrate diet.
How Is It Determined If The Dawn Phenomenon Or Somogyi Effect Is Causing The High Blood Sugar Levels
Your doctor will likely ask you to check your blood sugar levels between 2 a.m. and 3 a.m. for several nights in a row. If your blood sugar is consistently low during this time, the Somogyi effect is suspected. If the blood sugar is normal during this time period, the dawn phenomenon is more likely to be the cause.
Some additional clues that the Somogyi effect may be the cause include nightmares, restless sleep and overnight sweating as these are all signs of low blood sugar levels.

Blood Sugar Spike: What To Do
Its important to know the symptoms of hyperglycemia. If you suspect that you have high blood sugar, perform a finger stick to check your level.
Exercising and drinking water after eating, particularly if youve consumed a lot of starchy carbs, can help lower your blood sugar.
You can also use an insulin injection, but be careful only to use this method while closely following the recommendation of your doctor regarding your dose. If used improperly, insulin can cause hypoglycemia .
Does High Blood Sugar Make You Sleepy
Surprisingly, one of the symptoms of diabetes or pre-diabetes is excessive sleepiness. But the cause of it is probably different than youd guess.
Youd think that a high blood sugar would create a sugar rush, which would give you a boost of energy. Right?
That is true initially especially if youre healthy and you dont have insulin problems. But if you arent, then things are different for you.

Signs That Blood Sugar Levels Are High
People with high blood sugar may:
- pee a lot. When blood sugar levels get too high, the kidneys flush out the extra glucose into your urine , which is why people who have high blood sugar levels need to pee more often and in larger amounts.
- drink a lot. Because youre losing so much fluid from peeing so much, you can get very thirsty.
- lose weight. If there isnt enough insulin to help the body use glucose, the body starts to break down your muscle and fat for energy and you lose weight.
- feel tired. Because the body cant use glucose for energy properly, you may feel really tired.
High blood sugar levels dont always cause these symptoms. Sometimes you can have high blood sugar levels without even knowing it. But if left untreated, they can cause serious health problems. Thats why its important to work with your parents and diabetes team to keep your blood sugar levels in a healthy range. This can mean checking your blood sugar levels a few times a day, even when you feel fine.
Ask Your Doctor How Often You Should Be Checking Your Blood Sugar
Blood sugar control is crucial when youre living with type 2 diabetes. Dips and spikes can not only make you feel cranky and sluggish, but they can also wreak havoc on your personal health.
For the record, the;American Diabetes Association notes that you have diabetes if one of the following applies to you:
- Your blood glucose after fasting is 126 milligrams per deciliter or higher.
- Your blood glucose two hours after eating a meal is 200 mg/dl or higher.
- Your hemoglobin A1C is 6.5 or higher.
The tricky part is that with type 2 diabetes you may not feel it when blood sugar levels are too high, according to the ADA. It feels different for everyone. Not everyone will have the same symptoms, and some individuals will have no symptoms at all, says;Lori Zanini, RD, CDE, a Los Angelesbased former spokesperson for the Academy of Nutrition and Dietetics.
Because blood sugar management is so important to your overall health with type 2 diabetes, you need to take action if you think your levels may be out of control, even if youre feeling totally fine.
