What Happens To Blood Sugar While You Sleep

When to Test Your Blood Sugar During A Fast

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.

A Low Blood Sugar Level And Driving

You may still be allowed to drive if you have diabetes or you’re at risk of a low blood sugar level for another reason, but you’ll need to do things to reduce the chance of this happening while you’re driving.

You also need to tell the Driver and Vehicle Licensing Agency and your car insurance company about your condition.

Benefits: Weight Loss And Cleansing

Burning fat has several benefits for your health the first being weight loss. Ketosis is a predictable way to target fat stores that otherwise remain untouched even with a healthy lifestyle. Additionally, getting rid of that extra fat has a detoxifying effect on the body. Your bodys natural defenses use fat stores to store toxic metals and other toxins so they cant wreak havoc on your system. However, during ketosis, these toxic metals and toxins are safely expelled from your body as fat reserves get used up. This cleansing effect may temporarily alter some people’s complexion or cause other signs of a healing crisis.

What To Do After You Overcome A High Blood Sugar Reading

Make it a priority to understand what caused your high reading in the first place, so you can focus on how to prevent it from occurring again.

Was it something that you ate? A food with lots of simple sugars? Or did you drink a soda? If it was a food or drink, you know to avoid it in future and start making better choices.

Is it that you have been ignoring your diabetes and not taking care of yourself? And it may be that you have high blood sugar all the time? What can you do to rectify this? Eat better? Exercise more?

Was it a stressful event that caused this?

Was it an illness?

Potential Benefit Of Intermittent Fasting For Diabetes: It May Boost Weight Loss

What Happens If You Have Low Blood Sugar  Diabetes Care Talk

In previous years, dietitians and scientists thought of IF as a negative practice, so there isnt a wealth of high-quality clinical research on how it may affect people with diabetes, says Jason Fung, MD, a nephrologist in Toronto and coauthor of The Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting. But attitudes have begun to change, and some newer studies suggest the approach may have benefits, including for people with diabetes.

For example, a small study published in August 2021 in the journal Hormone and Metabolic Research found that IF lowered insulin resistance in 13 adults with type 2 diabetes. Insulin is a hormone that helps shuttle glucose out of the bloodstream people with type 2 diabetes are resistant to insulin, which results in higher blood sugar levels.

Its thought that losing weight through IF can lead to improvements in insulin sensitivity, too, says Michael Mosley, MD, a science journalist and coauthor of The FastDiet.

In addition, a review of existing research published in February 2021 in the journal Clinical Diabetes and Endocrinology included several studies that found IF reduced fasting glucose levels, weight, and post-meal blood sugar levels in people with type 2 diabetes. Even with these studies, though, further research needs to be conducted to see whether IF is truly safe for people with type 2 diabetes as a whole, experts say.

Blood Sugar Testing At Home

A person can test their blood sugar levels at home.

In most cases, doctors ask people to measure fasting blood sugar immediately upon waking and before they have anything to eat or drink. It may also be appropriate to test blood sugar before eating or 2 hours after a meal, which is when blood sugar returns to normal levels.

The right time to test depends on treatment goals and other factors. For example, most people with diabetes do not need to test between meals unless they are using a diabetes drug that can lower blood sugar. Other people may test between meals if they feel their sugar levels may be low.

Since people with type 1 diabetes do not make any insulin, they need to test their blood sugar levels several times a day so they can adjust their insulin doses.

A person will test blood sugar levels by:

  • preparing the testing strip and glucose monitor to be ready for the blood sample
  • using an alcohol swab to clean the testing area, which is usually the side of a fingertip
  • lancing the testing area and bracing against a firm surface to help resist the impulse to pull away
  • squeezing the testing area around the wound to maximize blood flow
  • squeezing a drop of blood onto the test strip
  • putting the strip into the monitor
  • recording the time, blood sugar reading, and recent food intake in a log

High Blood Sugar At : What Causes It

Poor diet and lack of medication are the biggest culprits of high blood sugar. Well be covering diet more below.

There are a few other causes for high blood sugar that may explain your high reading.

These include:

Work with your healthcare team to address any of the above concerns to optimize your glucose control.

Whats The Connection Between Blood Glucose And Ketosis

Blood glucose does not indicate whether youâre in ketosis, but it can be correlated with the ketone levels in your body.

Itâs also an indicator of your insulin sensitivity, or lack of. This is why blood glucose levels are used as one of the indicators of developing type 2 diabetes, which is strongly tied to insulin resistance.

Ketones aside, properly testing your blood sugar will give you better insight into your bodyâs response to specific foods even more than a ketone monitor. This is because your blood sugar will respond faster to the food youâve just consumed than your bodyâs ketones will.

Benefits Of Intermittent Fasting

What happens when you stop fasting?

A few small human studies have shown evidence that intermittent fasting can have health benefits for those with diabetes. These include:

  • Weight loss
  • Lowering insulin requirements

A long-term study, published in the New England Journal of Medicine, revealed that a fasting state can support several benefits including:

  • Lessening inflammation
  • Dehydration
  • Sleepiness during the day
  • Low energy levels
  • A significantly increased risk of low blood sugar
  • High blood sugar resulting from a surge of stored glucose from the liver when low blood sugar levels result from fasting

Its important to note that more research is needed to definitively back up the claims of side effects from intermittent fasting and to confirm the severity of such untoward reactions.

Because of the likeliness of side effects from fasting when a person has diabetes, its important to consult with your healthcare provider before deciding to start any type of fasting diet.

What Happens To Your Body When You Fast

Stage 01: 0 to 4 hours after a meal high blood sugar

Up to 4 hours after having a meal, your blood sugar remains high. The body is flushed with insulin to remove this blood sugar and convert it into glycogen. This spike in insulin results in a sugar crash due to which people start feeling hungry after 4 hours of a meal. The higher the glycaemic index of your meal the greater this crash will be. This is why high carb food keeps people hooked onto eating a lot.

Stage 02: 4 to 8 hours after a meal – low blood sugar

Blood sugar starts to drop and starts moving towards its normal levels.

Stage 03: 8 to 12 hours after a meal – Blood sugar is normal

Your blood sugar only returns to normal levels 12 hours after a meal Imagine what you put your body through when you consume high carb food.

Stage 04: 12 to 18 hours after a meal – Partial ketosis

This is the beginning of the Ketosis State. Ketosis is a metabolic state that allows your body to burn fat instead of sugars or glycogen. At this stage, the body is fueled by both metabolic pathways Ketosis and Glycolysis.

Stage 05: 18 to 28 hours after a meal – Ketosis and fat burning

The body primarily starts utilizing fats for energy. This state results in increased Ketone Bodies in your system. Research indicates that this state is also linked with an overall decrease in inflammation in the body. Rejuvenation and healing processes start to kick in. You start to feel more alert and attentive.

Fasting & Elevated Blood Glucose

Type 2 diabetes for 20+ years. Started keto with intermittent fasting in January 2019. Why would my fasting blood glucose numbers during my 18-24-hour fast be elevated, then come down to normal ranges after eating?

Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood. This is normal. If you are not eating, you want to use some stored glucose. The question is this if you are not eating, and your blood glucose went up, where did that glucose come from? It can only have come from your own body . So, its a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy.

Exercise And Blood Sugar

Exercise can have a big effect on your blood sugar levels because blood sugar is used for energy. When you use your muscles, your cells absorb sugar from the blood for energy.

Depending on the intensity or duration of exercise, physical activity can help lower your blood sugar for many hours after you stop moving.

If you exercise regularly, the cells in your body may be more sensitive to insulin. This will help keep blood sugar levels within normal ranges.

Whats Happening With Your Body: Battery Save Mode

Blood Sugar 101  Diabetes Daily

Several things happen at the cellular level that cause hunger and fatigue during this first stage. When youre eating regularly, your body breaks down glucose to get the energy it needs to function properly. While youre fasting, your body needs to produce sugar for energy, so it begins a process called gluconeogenesis. During gluconeogenesis, your liver converts non-carbohydrate materials like lactate, amino acids, and fats into glucose. As your body goes into battery save mode, your basal metabolic rate, or BMR, becomes more efficient and uses less energy. This power saving process includes lowering your heart rate and blood pressure. At this stage, you may feel drained. However, if you stick it out for a little longer, some of that lost energy will return.

Stick To Your Medication And Insulin Regimen

Skipping a dose of medication or insulin can be harmful to your body and increase your blood sugar levels.

Its important to stick to your treatment plan and follow your doctors instructions for taking your medication.

Summary

Healthful lifestyle habits can help people manage their blood sugar levels over the long term, such as eating a balanced diet, getting regular exercise, staying hydrated, and getting good sleep.

Normal Blood Sugar Levels Vs Hyperglycemia

If youve been diagnosed with diabetes, your endocrinologist will tell you what your target blood glucose levels are. Your levels may be different from what is usually considered as normal because of age, pregnancy, or other factors. You will be given two target levels, or ranges, one applying to when you haven’t eaten for a number of hours and one for after meals .

Hyperosmolar Hyperglycemic Nonketotic Syndrome : A Complication Of Severe Hyperglycemia In Type 2 Diabetes

In people with type 2 diabetes, extreme hyperglycemia can lead to a very rare but serious condition called hyperosmolar hyperglycemic nonketotic syndrome, or HHNS). HHNS is most likely to occur when you’re sick particularly if you aren’t able to drink enough fluids or keep fluids down. It happens most often in elderly people and, like ketoacidosis, can result in a coma.

What Is High Blood Sugar

How to Measure Your Blood Sugar When You Are Fasting? And What It Tells You

Elevated blood sugar levels are known as hyperglycemia. Blood sugar levels are measured using a small sample of blood that is tested in a lab. Blood sugar can also be tested using at home devices such as a handheld glucometer. Levels that indicate hyperglycemia are indicative of prediabetes and both type 1 and type 2 diabetes.

Normal ranges of blood sugar will vary depending on the test being done. In general, a normal fasting glucose level will be between 70-100 mg/dL. After a meal, these levels are expected to rise slightly around 1 to 2 hours after the beginning of a meal, but should be less than 180 ml/dL.

Maintaining healthy blood sugar levels is important not only for metabolic health, but heart health too. Over time, high blood sugar can damage blood vessels and the nerves that control your heart. People with diabetes are also more likely to have other conditions that raise the risk for heart disease:

  • High blood pressure increases the force of blood through your arteries and can damage artery walls. Having both high blood pressure and diabetes can greatly increase your risk for heart disease.
  • Too much LDL cholesterol in your bloodstream can form plaque on damaged artery walls.

Different Levels And What They Mean

The ranges of safe levels of blood glucose depend on factors such as what time of day it is and when you last ate. Safe levels of blood sugar are high enough to supply your organs with the sugar they need, but low enough to prevent symptoms of hyperglycemia or complications of diabetes which follow the National Institute of Diabetes and Digestive and Kidney Diseases guides. Dangerous levels of blood glucose are outside of this range.

The target levels can also vary if you have diabetes. For example, if you are diabetic and are monitoring your blood sugar, you might get a reading of 65 mg/dl. That is considered to be mild hypoglycemia, and you would be wise to eat 15 grams of fast-acting carbohydrates and retest your blood sugar in 15 minutes.

If you were not diabetic, you probably would not know that your sugar was low because you would not test and because you would not symptoms, and you would not act.

That is fine because your body is capable, under normal circumstances, of raising your blood glucose to healthy levels when needed, even if you have not eaten. It is important to keep them in control to help prevent issues like heart disease or nerve damage.

The : 2 Intermittent Fasting Diet

Thee 5:2 intermittent fasting diet is one type of popular fasting diets, introduced in Dr. Jason Fungs best-selling book “The Obesity Code” in 2016. The 5:2 diet involves five days of eating the recommended daily caloric intake and two non-consecutive days of eating a reduced-calorie diet. On fasting days, food is not eliminated altogether, rather, the number of calories is reduced.

If you have diabetes and want to try the 5:2 diet, speak to your healthcare provider or diabetic team and get a recommendation for a daily caloric intake guideline for fasting and non-fasting days.

Studies on the 5:2 Diet

Studies have shown that the 5:2 diet may help reduce insulin resistance and promote weight loss in people with type 2 diabetes or prediabetes.

The first long-term study of the 5:2 diet, published in 2018, by the Journal of the American Medical Association , discovered that intermittent fasting could be effective for those with diabetes who have trouble sticking to a long-term, daily diet regime. The study observed 137 people with type 2 diabetes half of the study participants followed the 5:2 diet and the other half adhered to a daily calorie-restricted diet . The group that fasted for two non-consecutive days per weekconsumed 500 to 600 calories on the fasting days and ate normally on the other five days of the week.

Preventing Low Blood Sugar Levels

Here are some other tips to help you avoid low blood sugar levels:

  • Eat all your meals and snacks on time and try not to skip any.
  • Take the right amount of insulin.
  • If you exercise longer or harder than usual, have an extra snack.
  • Don’t take a hot bath or shower right after an insulin shot.
  • Stick to your diabetes management plan.
  • Check your blood sugar levels regularly, so you can tell if your blood sugars are running too low and your treatment plan needs adjustment.
  • Carry something containing sugar with you at all times and take it right away if you have symptoms. Don’t wait to see if the symptoms will go away they may get worse!

Alcohol and drugs can cause major problems with your blood sugar levels, so avoiding them is another way to prevent diabetes problems. Drinking can be particularly dangerous even deadly for people with diabetes because it messes up the body’s ability to keep blood glucose in a normal range. This can cause a very rapid drop in blood glucose in people with diabetes. Drug or alcohol use is also dangerous because it may affect someone’s ability to sense low blood sugar levels.

Learning how to recognize the signs of low blood sugar levels and get them back to normal is an important part of caring for diabetes. Keeping track of your blood sugar levels and recording lows when they occur will help you and your diabetes health care team keep your blood sugar levels in a healthy range.
