When Is Blood Sugar The Highest

Normal And Diabetic Blood Sugar Ranges

For the majority of healthy individuals, normal blood sugar levels are as follows:

• Between 4.0 to 5.4 mmol/L when fasting
• Up to 7.8 mmol/L 2 hours after eating

For people with diabetes, blood sugar level targets are as follows:

• Before meals : 4 to 7 mmol/L for people with type 1 or type 2 diabetes
• After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes

Is Your Fasting Blood Sugar High Every Morning

I recently had an issue where no matter what I did, my fasting blood sugar levels were always high every morning. They were in the range of between 12 mmol/L to 16 mmol/L. At first I chalked it up to overdoing it around the holiday season. Eating way more carbs than usual, especially late at night and very close to bedtime. I figured that I was off with my bolus for the meals I ate at night. However, after I cut out the extra carbs and still got high readings in the morning, I knew something was off.

I realized that every morning religiously, I would wake up between 3 am and 4 am with a high blood sugar. Unfortunately if my blood sugar is above 8 mmol/L I cannot sleep. This problem prevented me from getting good quality sleep. I would often have to correct and monitor before I could go back to bed. I started to analyze my diet and my habits to see where I was going wrong. If you are experiencing a similar issue you can start with the below recommendations.

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.

Finding The Cause Of Your Morning Blood Sugar High

Though the three most likely causes of high morning blood sugar can all be treated, first you have to know which one is the source of your condition. “If youre not sure, you might have to take the somewhat inconvenient step of waking up to check your blood sugar levels in the middle of your sleep pattern ” suggests Amori. Heres why:

• Consistent blood sugar from bedtime until about 3 a.m. and then a rise suggests the dawn phenomenon.
• Low blood sugar at 3 a.m. suggests the Somogyi effect.
• Blood sugar that increases from bedtime to 3 a.m. and then is even higher when you wake is probably due to waning insulin.

Using a continuous glucose monitor enables you to get this information without having to wake up for it. “These monitors potentially help identify patterns and severity of high and low blood sugars,” explains Amori.

How To Test For Ketones

You can use a urine test strip or blood ketone meter and ketone test strip to test for ketones at home. Testing either urine or blood is important, but when possible, a blood test is preferred because it gives you and your care team more precise information about your ketone levels. Because urine may have been in the bladder for some time, the results from these tests may show levels that are either higher or lower than the ketone levels that are actually circulating in your body. It is also very important to know that urine test trips degrade over time, so if you are using this method, you need to look at expiration dates carefully.

Your diabetes care team can give you specific directions about when you should check for ketones, but in general, you should check for them when your blood glucose is 240 mg/dL or higher. You should also check for ketones if you notice any of the DKA symptoms listed above or if you are sick it is possible to have ketones while your blood glucose levels are within range .

At-home urine test strips will change color to show the level of ketones in the urine. They typically report results as negative, trace, small, moderate or large. Blood ketone meters will provide a number that indicates the ketone levels. The following ranges are generally used:

Treating High Morning Blood Sugar

A blood sugar high in the morning “can be tough to treat, acknowledges Amori, but with the help of your medical team, you can try different approaches. Talk with your doctor about these strategies:

Adjust your pump. If youre testing high regularly and you use an insulin pump, you might be able to program it to help manage your morning highs.

Check blood sugar before bed. Granted, many people have morning high blood sugar after an acceptable blood sugar before bedtime. Even so, “don’t go to bed with high blood sugar,” cautions Amori.

Take basal insulin. Taking basal insulin at bedtime could help, but be sure to clear any changes in dosing with your physician before you try it.

Adjust medication. If in fact your high morning blood sugar is a rebound response to a low blood sugar level while youre asleep, you might need to change the dose of any medication you take in the evening that could be causing low blood sugar. Talk with your doctor about whether your medication schedule should be adjusted to treat morning highs.

Have a healthy pre-bed snack. For those experiencing the Somogyi effect, a healthy mixed snack of protein and carbohydrates could help prevent your blood sugar roller coaster at night. Amori advises working with a registered dietitian if youre not sure how to fit a pre-bed snack into your daily diet.

Causes Related To Diet

Processed foods and sugar

Diet and how it relates to blood glucose values can vary immensely from person to person. But, research suggests that eating processed foods can increase blood glucose.

Overeating or grazing

Itâs a common belief that snacking throughout the day will keep blood glucose levels steady. But, a 2013 study found that eating two large meals per day helped reduce blood glucose more effectively than six small meals per day. Itâs also important to keep our meals to the right proportions, as overeating can raise blood glucose levels as well.

Dehydration

Some research has found a connection between low water intake and a greater risk of hyperglycemia. This is most likely because less water in the body means the concentration of glucose in the blood is higher.

Vitamin and mineral deficiencies

Research into this cause is ongoing. Yet, studies suggest diets lacking micronutrients like chromium, magnesium, or vitamin D may contribute to high blood glucose.

Normal Range Of Blood Sugar Levels

The normal range of blood glucose levels for individuals with diabetes is between 80 and 130 milligrams per deciliter . When levels are too low, the person may experience hypoglycemia, which is characterized by shakiness, sweating, dizziness, or confusion. When blood sugar levels are too high, the person may experience hyperglycemia, which is characterized as extreme thirst and urination and blurred vision. Blood glucose levels can be checked by pricking a finger to get a drop of blood and putting it on a glucose meter.

The normal blood sugar range is between 80-120 mg/dL .

When To See A Healthcare Provider

Getting professional medical advice from a healthcare provider like an endocrinologist is the best way to learn more about whether your blood sugar levels are where they should be. Not getting proper treatment for low or high blood sugar levels can be serious and lead to health complications, especially for those with diabetes. Diabetes complications include nerve damage, kidney disease, heart disease, or heart attacks.

If you see a healthcare provider about your blood sugar levels, be prepared to answer questions about risk factors like what you eat, how much you exercise, and about your family history. Some healthcare providers may want to take a blood sample to test your blood sugar levels. They may also order an A1C test, which is a blood test that measures blood sugar levels over several months. You may have to fast eight hours beforehand to get accurate test results, so its always a good idea to check before your appointment.

If your blood sugar level goes above 250 mg/dL, you should go to the ER for immediate medical attention, says Dr. Tarugu. Emergency rooms are equipped to handle high blood sugar levels and can administer treatments like insulin therapy and fluid or electrolyte replacement.

Treatment For High Blood Sugar Levels

For those with high blood sugar levels, it is vital to keep track of your blood sugars at home on a daily basis. This can be done with a glucose meter. These test monitors are often provided to diabetic patients so that they can manage their blood sugar levels at home everyday. They are available to purchase online if you are non-diabetic but wish to check on your levels regularly for safety.

Diabetic patients can be prescribed medications to help with insulin levels when their blood sugar is high. Those with type 1 diabetes will be prescribed medication which needs to be taken several times daily. This type of diabetes has no cure but can be managed with the right medication.

Those with type 2 diabetes or gestational diabetes can treat their high blood sugar with a change in diet or exercise. A healthier balanced diet is usually advised and sometimes, insulin medication is also prescribed if the blood sugar level becomes abnormally higher than the high reading for diabetic patients.

How To Check Your Own Blood Sugar Level

One way to check ones own sugar level is by pricking a finger with a lancet and placing the blood that comes out onto a test strip, then inserting the strip into a glucose monitor. A meter can tell you what your levels are in about 5 seconds. Another option is by taking an oral glucose tolerance test , which takes longer but may also provide more accurate results. A persons individual level will depend on many factors including how old they are, their ethnicity, their weight and height, and the activity theyve performed recently. Blood sugar levels can be checked by pricking a finger to get a drop of blood and putting it on a glucose meter.

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

The Diabetes UK website has more about blood sugar levels and testing.

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 you’re losing so much fluid from peeing so much, you can get very thirsty.
• lose weight. If there isn’t 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 can’t use glucose for energy properly, you may feel really tired.

High blood sugar levels don’t 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. That’s why it’s 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.

Why Do People Get Blood Sugar Spikes After Meals

When people eat a meal, especially when it contains carbohydrates, it is normal for them to have a temporary spike in their sugar level before the insulin their body produces immediately starts working to lower the spike. For someone with type 1 diabetes, who cant produce their own insulin, these spikes can be higher and last longer.

This is because it can take longer for the type of insulin they inject to start working, in comparison to the insulin that is produced naturally by the body of someone who does not have diabetes, to reduce these post-meal spikes.

Furthermore, it is important to know that people living with type 1 diabetes may have alterations in different digestive enzymes which will cause faster digestion of our meals . This can obviously impact on the size of the spike too.

What Is Blood Sugar Level

Whenever you eat something, your body breaks down that food into glucose and the count of that glucose in the blood is called blood sugar levels. The breakdown happens in order to provide you with energy. Energy generation is possible only when that glucose or sugar gets transferred into your body cells and does not remain in the bloodstream. If they remain there, your blood sugar level increases, and you get prone to diabetes.

When Should You Check Your Blood Sugar Levels

Its important that people who suspect they have diabetes or pre-diabetes monitor their glucose levels regularly, checking at least once daily and charting the results in order to know what is normal for themselves. If it seems like something isnt quite right with ones blood glucose. It may be time to talk to a doctor about getting a diabetes diagnosis. Its also important that parents make sure their children are well aware of any symptoms of high or low blood sugar. So they know when they need to alert an adult about what might be going on if their parents are not around.

Not Taking Enough Meal Time Insulin

This is the first thing to look into. Make sure that you correctly determine the number of carbohydrates in your last meal of the day and take the insulin to suit. Be sure to also look out for sources of hidden carbs as well. Our bodies react to food and insulin differently at different times of the day. Many individuals including myself have a different carb to insulin ratio at night. I normally have to take a bit more insulin at night especially if the meal is high in carbohydrates.

Try eating your last meal at least 2 hours before bed so that you can check the 2 hour post dinner blood sugar reading. This will indicate if you are indeed giving the correct amount of insulin. If you have a good reading before bed but its much higher in the morning, then there is definitely another issue.

People With Gestational Diabetes

Gestational diabetes can occur during pregnancy. Often, it is a temporary condition, but it can lead to pregnancy complications.

The American Diabetes Association recommends that people with a diagnosis of gestational diabetes aim for blood sugar levels similar to those for people without diabetes, although individual targets may vary.

The ADA offers the following as a guideline:

• kidneys
• blood vessels

A wide range of complications can also result, such as slow wound healing and frequent infections. Other possible complications include:

Phipps explains that, despite containing similar amounts of carbohydrates, one serving of pasta could have a hugely different effect on your blood glucose levels than one serving of rice. Likewise, that serving of pasta may have an entirely different effect on your blood glucose levels than your friendsâ or even family membersâ. âWeâre all unique,â Phipps says.

Low Blood Sugar: What To Watch Out For

Hypoglycemia can occur in people with diabetes who:

• Take too much medication or insulin
• Are late eating a meal or snack
• Have increased physical activity
• Drink too much alcohol

Symptoms of low blood sugar include feeling weak, sweaty or clammy, confused, hungry and/or irritable. Sometimes people experience a fast heartbeat and some symptoms may make a person appear to be drunk. A severely low blood sugar can result in unconsciousness, seizures, coma or death especially when a low occurs during the night.

Low blood sugar affects many parts of the body, but the most frustrating part can be that hypoglycemia can happen anytime and anywhere even when you think you are closely following the plan for your diabetes care. If low blood sugar is severe, people may need to go to the hospital to help raise their glucose level or miss work due to the side effects.

It can happen during a date, during a business meeting, or even while driving, which is the most dangerous scenario if there is confusion or loss of consciousness while behind the wheel. Its important to use your blood glucose meter to check your blood sugar before you drive to keep yourself and others safe. Frequent testing with your blood sugar meter and taking action when blood sugar is trending low can prevent a severe low and keep your life on track.
