154 blood sugar: Is 154 in sugar level when fasting bad for a type 2 diabetic?
High blood sugar levels in the morning: Causes, testing, and treatment
Most people have slightly higher blood sugar levels in the morning, but these can be significantly higher in some people with diabetes. Hormonal fluctuations and waning insulin are possible reasons.
Diabetes is a condition that impairs the body’s ability to process blood glucose. Without careful management, blood sugar levels can become too high, which is known as hyperglycemia. Long periods of high blood sugar levels can result in health complications.
Even when a person carefully controls the condition, they may notice blood sugar spikes in the morning. There are three main causes of high blood sugar in the morning:
- the dawn phenomenon
- waning insulin levels
- the Somogyi effect
It is important to note that this article refers to effects experienced in the morning, but these effects may occur anytime a person sleeps for a long period. People who work at night and sleep during the day can also experience these effects.
In this article, we will explore these causes, including what they can mean for a person’s health and when to see a doctor.
The dawn phenomenon refers to periods of hyperglycemia that occur during the early morning hours. The shift in blood sugar levels happens as a result of hormonal changes in the body.
Hormones, such as cortisol, glucagon, epinephrine, and growth hormone are known as counter-regulatory hormones. They can cause blood sugar levels to rise. The activity of cortisol and growth hormone normally increases each day to stimulate the liver to produce glucose at dawn.
This is why everyone experiences a slight rise in their blood glucose levels to some extent in the morning. A person without diabetes will not experience adverse effects, as their body can produce insulin to adjust. However, a person with diabetes is unable to produce sufficient or effective insulin. As such, this can cause a spike in their blood sugar levels and may require treatment to adjust their levels.
When the dawn phenomenon occurs, it may coincide with when nighttime levels of insulin begin to taper off. Reasons for the drop in insulin can vary. However, it often occurs when a person administers too little basal insulin, or when they inject it too early, causing its effects to wear off earlier than desired.
Different types of insulin work at different speeds and durations. Most types reach a peak when they are most effective. After the peak, the insulin’s effect begins to wear off. If people notice their blood glucose increasing overnight, then they may need to adjust their basal insulin and increase the dosage.
Some scientists believe there is another cause of high blood sugar in the morning: the Somogyi effect, also called rebound hyperglycemia. Named after Dr. Michael Somogyi, this theory suggests that blood sugar levels rise in response to a bout of late night hypoglycemia, or low blood sugar. This could occur if a person administers too much insulin or does not eat enough food before bed.
Not all experts agree on the Somogyi effect, and the scientific community still debates the theory. However, a 2015 study shows that the Somogyi effect was the most common cause of fasting hyperglycemia in individuals with type 1 diabetes and poor glycemic control.
If a person begins to notice a frequent occurrence of morning hyperglycemia, then they should check their blood sugar levels at bedtime, in the middle of the night, and upon waking to better understand their glucose patterns and identify the cause.
A person can use a continuous glucose monitor (CGM) to help them track and monitor their blood glucose throughout the night and day. This wearable medical device can collect data on a person’s blood sugar levels while they sleep.
Treatment options will vary depending on the data the CGM or individual glucose checks provide. By tracking when the highs and lows occur, a doctor will be able to recommend suitable strategies.
If the data shows that a person has high blood sugar at bedtime, then it is likely that food and medication are responsible. If a person has hyperglycemia before they sleep, it can persist until morning. Either a large meal close to bedtime or using too little insulin may be the cause. A person can adjust this by changing what and when they eat and slightly increasing their insulin dosage.
If a person is within their target range at bedtime but wakes with high blood sugar, they may be using too little basal medication or using it too early. Changing the timing of the long-acting dose, switching to a twice-daily basal insulin, or using an ultra-long-acting basal insulin may be beneficial.
Data demonstrating that a person has high blood sugar between roughly 3–8 a.m. suggests the dawn phenomenon. In this case, a doctor may recommend that a person does not increase their long-acting insulin, as this could cause hypoglycemia during the night. It may be advisable to consider an insulin pump, as a person can program it to automatically deliver more insulin in the early morning hours.
Some research also indicates that the following lifestyle changes may help control morning glucose levels.
- exercising in the evening
- increasing the proportion of protein to carbohydrates in the evening meal
- eating breakfast every day
Anyone who experiences high blood sugar levels in the morning should speak with a healthcare provider, who will identify an effective way to manage these levels.
If a person does not receive appropriate treatment, regularly experiencing high morning glucose levels can increase their risk of:
- insulin resistance
- cardiovascular disease
- more rapid disease progression
It is important for a person with diabetes to be aware that their blood sugar levels may rise in the morning and to receive treatment if this occurs.
If high glucose levels persist and get worse, complications can arise. For example, in people with type 2 diabetes, insulin resistance will increase, and the condition can progress more rapidly, which can increase the risk of potential health complications.
High Blood Sugar in the Morning: what to do
February 10, 2021
The facts are clear: many with diabetes experience high blood sugar in the morning. Indeed, this occurs for more than half of people with diabetes, according to this study.
What’s less clear is why this happens: there are a couple of different theories. But that doesn’t mean that you can’t do something about it.
You can find out what steps to take right here! And – since it is a fascinating curiosity – you can use this blog post to build your knowledge on blood sugar, along with our related posts: Low Blood Sugar at Night and High Blood Sugar at Night.
Signs of high Blood Sugar in the Morning
High blood sugar is significant when it’s too high. That’s when it’s called hyperglycemia. Hyperglycemia is usually defined as above 126 mg/dL or 7.0 mmol/L in a period of fasting (before eating). This will be the clearest sign of high blood sugar in the morning.
Before breakfast, you usually would have had a period of at least eight hours without eating (because you’re sleeping). As such, hyperglycemia during a period of fasting is particularly important here: you’ll know that the high blood sugar wasn’t caused by any recent meals.
Other signs of high blood sugar in the morning will be the usual symptoms of hyperglycemia:
- Nausea
- Feeling faint or weak
- Thirst
- Tiredness
- Blurred vision
- Increased urination
Of course, it’s normal to feel somewhat groggy and thirsty when waking. It’s important to distinguish between hyperglycemia and the I-hate-Mondays morning tiredness. And the best way to do that is to test your blood sugar.
Why is my Blood Sugar high in the Morning?
High blood sugar in the morning is mysterious to the extent that it may be a “phenomenon”. Specifically: the dawn phenomenon.
This is where hormones (like adrenaline) are released in the early hours of the morning. In turn, the hormones make the liver release its store of glycogen (which becomes glucose), thus raising blood sugar levels.
It’s not exactly known why this happens, but these hormones are usually released to give extra energy. So, the theory is that the body releases extra glucose in order to give you extra energy to wake up and start the day.
Obviously, this extra glucose doesn’t help those with diabetes, but at least the body’s trying. It’s the thought that counts, right?
There may also be another potential reason for high blood sugar in the morning: the Somogyi phenomenon (it’s a Hungarian name, in case you were wondering). This can occur as a result of insulin use.
It’s theorised that taking insulin before bed can cause the body to have a rebound effect whilst sleeping. If insulin continues to lower blood sugar during sleep, and it’s not being treated, then the body responds in stress mode: it releases hormones (like adrenaline again) to trigger a rise in blood sugar levels.
But for those with diabetes, this doesn’t stabilise the blood sugar. That extra glucose can’t be used without diabetes medication, and so, the blood sugar gets too high instead.
There could be other reasons for high blood sugar in the morning, such as too many carbs before bed or requiring a different level of insulin. We can look at what to do about that in a moment.
How to Lower Blood Sugar in the Morning
As with any time of the day, lowering blood sugar will usually mean taking medication.
If you’re taking other medication for diabetes, just make sure you’re taking the right amount at the right time of day. With insulin, you might want to use insulin to lower your blood sugar back to a stable level.
To figure out how much insulin you might need, you can let Hedia assist you in your calculations. Tell Hedia what your blood sugar level is, and the insulin calculator will take your basal insulin into account.
If you’ll be having breakfast soon after waking, you’ll probably want to include that in your calculation. If you have a favourite breakfast that you eat most mornings, you can add that to your favourites in Hedia’s food database for a quick add. Find out more by getting Hedia from the App Store or from Google Play!
On the topic of breakfast, it may be worth considering a low-carb breakfast, so as not to push those blood sugar levels even higher.
Regardless of what you’re eating, Christel Oerum from Diabetes Strong points out the importance of eating any kind of breakfast. Having regular mealtimes that give you the energy that you need throughout the day ought to allow you more stable blood sugar without the adrenaline swings.
How to Prevent Morning Hyperglycemia
While morning hyperglycemia could be the body’s automatic response, you can certainly take steps to try to prevent it.
General steps
You could try some general steps that could help lower blood sugar in the night, such as eating your evening meals earlier in the day or having fewer carbs in your evening meal.
Alternatively, you could consider doing exercise in the evening, such as a brisk walk before bed. You might also consider changing your medication doses for the night or changing the type of insulin you use. As always, make such changes in consultation with your healthcare professional.
Dawn phenomenon
If you think that the high blood sugar might be caused by the dawn phenomenon, then try to make sure that you are well-rested. If your body is getting enough rest, with a full eight hours of sleep, then it might not think that it needs to release that extra energy. More generally, stress and diabetes leads to higher blood sugar levels – so it is worth getting enough sleep.
Somogyi phenomenon
With the Somogyi phenomenon, you’ll want to take the opposite steps because you want to prevent low blood sugar during the night. It may seem somewhat counterintuitive, but you might need to take less insulin, or eat more carbs, or do less exercise before bed.
It can be difficult to determine what caused your morning high blood sugar. And so, many of these steps will be trial-and-error until you find the right fit for you. Make sure to seek advice from your healthcare professional when going through this trial-and-error.
Last but not least, keep checking your blood sugar levels before bed: that’s the best way to get an idea of what your blood sugar is up to. If you want to be a real detective, you could try setting an alarm to wake you in the night in order to find out what your blood sugar level would be when you are sleeping.
No more high Blood Sugar in the Morning
It’s important to recognise that morning hyperglycemia is fairly normal: it’s usually your body trying to get you ready for the day (bless its cotton socks).
But you can help your body help itself by trying out some changes in your routine or medication. And Hedia wants to help you to help your body to help itself! Give yourself a good morning by visiting the App Store and Google Play ☀️
When “sugar jumped” – Regional newspaper OGIRK.RU
More than 80 thousand residents of the Irkutsk region are diagnosed with diabetes. Although in 1976 less than 5 thousand people were ill with it. The disease is fraught with the most serious consequences, but with due attention to health, this is not a sentence. From 2023, schools for people with diabetes will operate on a permanent basis in the country, including in our region. Their main task is to improve the quality of life of patients and prevent complications.
Three chair disease
Experts call the situation with the spread of diabetes dramatic. There are more and more patients every year in all countries, and Russia is no exception. We now officially have this diagnosis confirmed in about 5 million people.
But doctors believe that the real figure is about 12-13 million. Recently, they conducted research in different cities, including. in Irkutsk. The people who participated in them did not even suspect that they had such a disease. These are those who suffer from the second type of diabetes. It has chronic hyperglycemia – high blood glucose levels.
– Risk factors for developing type 2 diabetes – overweight, obesity, high blood pressure, high blood lipids, which include cholesterol. Genetics play a big role. If there are grandparents with diabetes in the family, the younger generations should think about and lead the right way of life. It is necessary to reduce the amount of easily digestible carbohydrates in the diet. Our daily life has changed. First, it’s stress. Secondly, physical activity has decreased. Diabetes mellitus is a disease of “three chairs”. We sit at work, in front of the TV and in the car0215 – states the chief freelance endocrinologist (adult) of the Ministry of Health of the Irkutsk region Tatyana Bardymova .
The incidence of diabetes in children is also on the rise. And, as a rule, the first type, when the patient needs insulin injections. In 2020, the disease was detected in 104 children, in 2021 – in 154, this year – in 124. In total, the diagnosis was confirmed in 869 minors in the region.
– Unfortunately, the incidence of morbidity in young children is now noted. This year, 20 kids under the age of four fell ill. The mechanism of development of type 1 diabetes is significantly different. This is where genetics comes into play. A child is born with a certain sequence of genes that are predisposed to developing the disease. And environmental factors act as triggers. Parents need to pay attention to the first signs of diabetes, when the child begins to weaken, lose weight, drink often and a lot, go to the toilet often. In this case, you need to take a blood test for sugar, consult a doctor. In type 1 diabetes, all children receive two types of insulin, – explained the chief freelance specialist endocrinologist (children’s) of the Ministry of Health of the Irkutsk region Lyudmila Kholmogorova .
Less candy, more movement
Diabetes is often diagnosed late. After all, high blood sugar “does not hurt.” Complaining is a complication. Diabetes is a medical and social disease. People with diabetes become disabled at a young, working age. The disease has a detrimental effect on the cardiovascular system: the risk of heart attacks, strokes, and vascular lesions of the lower extremities increases. Blindness may occur.
– For prevention, in addition to the normalization of nutrition, the use of less easily digestible fatty acids, you need to move more. And it is important to participate in medical examinations, and after 40 years – annually. It is carried out in polyclinics at the place of residence and usually does not take much time. Even at the stage of questioning a doctor, risk factors can be identified. Since the beginning of the year, during medical examinations in the region, about 25 thousand people were diagnosed with obesity, about 15 thousand with diabetes, – said the deputy chief physician of the Irkutsk Regional Center for Medical Prevention Sergey Belykh .
Experts agree that this diagnosis in itself is not a sentence. Now medicine has advanced in the methods of treating the disease, although it is chronic. The same insulin of domestic production is not inferior in quality to foreign analogues. Test strips for glucometers are produced in Irkutsk, and now they have begun to produce hypoglycemic tablets.
Doctors consider the education of patients to be the most important direction. The State Duma of the Russian Federation in the second reading is considering a draft federal program to combat diabetes, where our region will participate. The Governor of the Irkutsk region Igor Kobzev met with the director of the State National Medical Research Center of Endocrinology Natalya Mokrysheva this year. At the meeting, it was decided to create a regional endocrinological center in the Baikal region.
– From next year, the draft program provides for the training of patients with diabetes mellitus and their relatives on an ongoing basis.
