Can Not Eating Raise Blood Sugar

Time Your Bolus Insulin Properly

For people who take rapid-acting insulin at mealtimes, the timing of the bolus can have a huge impact on after-meal blood glucose levels. Boluses given too late to match the entry of glucose from dietary carbohydrates into the bloodstream can produce significant blood glucose spikes soon after eating. A properly timed bolus, on the other hand, can result in excellent after-meal control.

Unless you have gastroparesis , it is best to give bolus insulin doses before eating. How long before? It depends mainly on what you are eating and on your pre-meal blood glucose level.

Figuring out the pre-meal blood glucose part is fairly straightforward: the higher your blood glucose, the earlier the bolus should be given. If your pre-meal blood glucose is well above your target, it is best to give the bolus and then wait at least 30 minutes before eating. Near your target blood glucose? Wait 15 minutes. Below target? Either take the bolus and eat right away, or take the bolus after eating to manage high blood glucose.

Does earlier bolusing make a difference? Absolutely. Research has shown that simply giving mealtime boluses before eating rather than after eating can reduce the post-meal spike by about 45 mg/dl.

Signs And Symptoms Of Reactive Hypoglycemia

Symptoms of reactive hypoglycemia can include:

• Anxiety

When talking about the signs of reactive hypoglycemia, its important to note that many of these symptoms can be experienced without actually having low blood sugar

In fact, it is rare for such symptoms to be caused by falling blood sugar levels after eating, with the actual cause for many people often relating to what food was eaten or variations in the timing of the food moving through the stomach and intestinal tract.

If there is no hypoglycemia at the time of the symptoms, you may have what is known as postprandial syndrome.

Low Blood Glucose During Sleep

Your blood glucose level can drop while you sleep and stay low for several hours, causing serious problems.7 Symptoms of low blood glucose while you sleep can include

• crying out or having nightmares
• sweating enough to make your pajamas or sheets damp
• feeling tired, irritable, or confused after waking up

Although you may not wake up or notice any symptoms, low blood glucose can interfere with your sleep, which may affect your quality of life, mood, and ability to work. Having low blood glucose during sleep can also make you less likely to notice and respond to symptoms of low blood glucose during the day.

Blood glucose originates from the foods you eat. A hormone called insulin assists move the sugar from your blood stream into cells in your body, where its utilized for energy. But if your blood glucose levels drop too low, you can experience a wide variety of signs, some of which can be severe.

• Avoid drinking alcohol on an empty stomach. Alcohol can cause blood sugar to drop.

• Have a light snack before exercising. Good choices are crackers and peanut butter, yogurt and fruit, half a turkey sandwich, or a bowl of whole grain cereal with milk. A snack at bedtime can help keep blood sugar levels normal during the night.

• If you have diabetes, you need to match your carbohydrate intake to your diabetes medications to avoid low blood sugar. A or diabetes educator can help you put together an eating plan. If you take mealtime insulin like insulin aspart , insulin lispro , or insulin glulisine , make sure you eat the right amount of carbohydrates at your meal to match your insulin dosage. Skipping meals or not eating enough carbohydrates can cause your blood sugar level to dip significantly.

If you find that youre eating less due to an illness or other factors, your medications may need adjusting, so its important to talk to your doctor. Meanwhile, here are some general guidelines:

• Mealtime insulin: For mealtime insulin, if you skip the meal, you should also forego the mealtime insulin.
• Long-acting insulin: The dosage for long-acting insulin is not usually based on food intake, so your doctor will not likely recommend a dose reduction.
• Other medications: There are some diabetes medications that will lower your blood sugar when high, but wont normally cause hypoglycemia. They may or may not need adjustment, depending on how much youre eating. These medications include metformin, SGLT-2 inhibitors and DPP4 inhibitors.

What Are The Symptoms Of Low Blood Glucose

Signs of low blood sugar vary from person to person and can even be various from one episode to the next. You might experience particular signs the first time your blood sugar dips, and different signs the next time. The most frequent mild to moderate symptoms of low blood sugar include:

jitters or shaking

More severe signs of hypoglycemia include:.

inability to eat or drink. seizures. unconsciousness. Sometimes, a condition called hypoglycemia unawareness can establish after regular episodes of low blood sugar. This takes place due to the fact that the body gets used to low blood sugar, so symptoms end up being harder to determine.

Hypoglycemia unawareness can be dangerous, as it lowers the opportunity for dealing with low blood sugar level and increases the probability of serious hypoglycemia. For moderate to moderate symptoms, you can usually take actions yourself to get your levels into the regular variety. For severe signs, its essential to get immediate medical support.

You May Bonk Midway Through Your Workout

Bonking, or experiencing reduced energy due to low blood sugar, is another potential effect of skipping meals that can be particularly dangerous for people with diabetes. Signs of bonking include dizziness, nausea, and shakiness, says Goergen.

Glucose feeds your cells while you’re exercising, but without fuel from food, the body begins burning fats to create glucose, causing acids called ketones to accumulate in the body. Your muscles may experience fatigue during physical activity simply because your body has run out of energy from its usual energy source, says Goergen, explaining that this process is called ketosis.

More important, if you take diabetes medication that is meant to help lower your blood glucose levels, but you don’t fuel your body with carbohydrates to provide that glucose, you may become hypoglycemic. Hypoglycemia, or low blood sugar, can lead to dizziness, shaking, blurred vision, headache, confusion, and nausea during your workout. If left untreated, hypoglycemia can be life-threatening, Goergen says.

Prevent low blood sugar by eating a little something before your workout, such as a small banana or pressed fruit bar, recommends Stefanski. Sometimes planning a workout about 60 minutes after a meal can be a good way to keep blood sugar stable, have good energy, and not have to add extra food into the day just for the workout, she says.

Whether you were recently diagnosed with type 2 diabetes or have been living with the condition for several years, you know how fickle blood sugar levels can be, and how important it is that they stay controlled.

Proper blood sugar control is key for warding off potential diabetes complications, such as kidney disease, nerve damage, vision problems, stroke, and heart disease, according to the National Institutes of Health . Plus, keeping your levels in check on a daily basis can help you stay energized, focused, and in a good mood, explains Lisa McDermott, RD, CDCES, a diabetes specialist with the Pittsburgh-based Allegheny Health Network.

According to the American Diabetes Association , proper medication, effective meal planning, regular exercise, and regular blood sugar checks can all help you keep your levels within a healthy range. The ADA recommends blood glucose stay within 80 to 130 milligrams per deciliter before meals and below 180 mg/dL two hours after the start of a meal. Furthermore, the organization recommends getting an A1C test, which measures your average blood glucose over the past two to three months, at least twice per year if your levels are stable and you are meeting treatment goals.

• Lifestyle Risk Factors

High blood sugar or glucose, also called hyperglycemia, occurs when there is too much sugar in the blood. High blood sugar is the primary symptom that underlies diabetes, but it can also occur in people who dont have type 1 or type 2 diabetes, either because of stress or trauma, or gradually as a result of certain chronic conditions.

It is important to manage high blood sugar, even if you dont have diabetes, because elevated blood glucose can delay your ability to heal, increase your risk of infections, and cause irreversible damage to your nerves, blood vessels, and organs, such as your eyes and kidneys. Blood vessel damage from high blood sugar also increases your risk of heart attack and stroke.

Hashimotos Fasting And Keto

I believe there is a way to reverse Hash! I feel so much better on keto and IF than any treatment over the past three years. Have you had any patients reversing Hashi with this program?

Thank you so much for all your work for all of us,Martha

Answer: I dont see Hashimotos very frequently so dont have much experience. Fasting and low carb diets usually drop insulin so are effective for diseases of excessive insulin such as obesity, type 2 diabetes and PCOS. However, it may also have a smaller effect on inflammation so it may certainly benefit Hashimotos as well, but there are no studies to prove this, and I have only limited clinical experience with Hashimotos.

What Are The Treatments For Hypoglycemia

Make an appointment with an endocrinologist if you feel like youre having episodes of hypoglycemia, even if youre not diabetic. Theyll talk you through treatment strategies, including:

• Adjusting your medications. You may need to change how often you take insulin or other medications, which medications youre on, how much you take, and when you take them.
• Working with a registered dietitian on a personalized meal plan that stabilizes blood sugar levels. Theres no one-size-fits-all hypoglycemia diet, but a nutritionist can help you figure out a consistent meal plan tailored to you, and teach you how to count carbohydrate grams to go along with your health and routine.
• Increasing and improving self-monitoring of your blood glucose levels. Knowing your blood glucose level throughout the daywhen you get up, before meals, and after meals etc.can help you keep it from getting too low.
• Limiting consumption of alcoholic beverages. Alcohol interferes with the way your body metabolizes glucose. If you’re prone to hypoglycemia, consider decreasing how much alcohol you consume.
• Glucose tablets . Make sure you always have glucose tablets on hand, whether at home, school, the office, or the gym. After taking the tablet, check your blood sugar. If its still low, take another tablet. If that doesnt help, check with your doctor.

Its Strange That Blood Sugar In A Diabetic Can Rise Despite Not Having Eaten Anything Since Typically Eating Causes Blood Sugar To Go Up

But its no uncommon occurrence that in diabetes, glucose or blood sugar levels can actually rise in the absence of eating.

When we dont take food into our body for energy, our liver will try to help us by releasing glucose into our blood so we have the energy we need to stay alive, says Lucille Hughes, RN, CDE, director of diabetes education at South Nassau Communities Hospital in Oceanside, NY.

For people with diabetes, the liver may release too much glucose, causing blood sugar to go up.

This is why its so important for diabetics to regularly take blood sugar readings, even if they feel fine.

The liver has hundreds of jobs. One of those jobs is to release glucose into the bloodstream for energy because the body requires energy to function, even when at rest.

Basic bodily functions require energy and glucose provides that energy.

In diabetes, things are out of whack in the body. The liver in the diabetic may sometimes overestimate how much sugar to release into the bloodstream.

Or, to put it another way, the liver over-corrects the problem.

The only way that a diabetic can stay ahead of this curve is to monitor their glucose levels on a regular basis throughout the day to make sure that the sugar level doesnt sneak its way into getting into a dangerously high range.

The reason blood glucose tends to spike after eating in many people with diabetes is a simple matter of timing. In a person who doesnt have diabetes, eating foods containing carbohydrate causes two important reactions in the pancreas: the immediate release of insulin into the bloodstream, and the release of a hormone called amylin. The insulin starts working almost immediately and finishes its job in a matter of minutes. The amylin keeps food from reaching the small intestine too quickly . As a result, the moment blood glucose starts to rise, insulin is there to sweep the incoming glucose into the bodys cells. In most cases, the after-meal blood glucose rise is barely noticeable.

However, in people with diabetes, the situation is like that of a batter with very slow reflexes facing a pitcher who throws 98-mph fastballs: The timing is all fouled up. Rapid-acting insulin that is injected at mealtimes takes approximately 15 minutes to start working, 6090 minutes to peak, or reach maximum effectiveness, and four hours or more to finish working. Meanwhile, amylin is either produced in insufficient amounts or not at all, so the movement of food from the stomach to the intestines is not slowed the way it should be. As a result, food digests even faster than usual. This combination of slower insulin and faster food can cause the blood glucose level to rise quite high soon after eating. Once the mealtime insulin finally kicks in, the high is followed by a sharp drop.
