Dipping Blood Sugars Cause Surprisingly Irregular Heart Rhythms In Diabetics
â¢Research unveils clues to âDead in Bedâ cases where young people without any history of long-term complications die suddenly from diabetes.â¢Low blood sugar levels lead to heart rhythm disturbances and even life-threatening heart attacks.
Dangerous overnight blood sugar levels often go undetected and cause prolonged periods of heart rhythm disturbances in older patients with Type 2 diabetes and associated heart problems, new research reveals.
The findings from the research â led by Professor Simon Heller of the University of Sheffieldâs Department of Human Metabolism and Sheffield Teaching Hospitals NHS Foundation Trust – could offer vital clues to the mechanism by which low blood sugar levels could contribute to life-threatening changes in heart rhythm, a major risk for patients with diabetes.
They also shed important new light on the âDead in Bedâ syndrome â where young people without any history of long-term complications die suddenly from the disease.
Previous studies have apparently ruled out a direct effect of hypoglycaemia as a cause of death in patients with Type 2 diabetes.
The breakthrough research was conducted by Elaine Chow, a specialist registrar at Sheffield Teaching Hospitals and the University of Sheffield under a Â£190K Biomedical Research Fellowship awarded by the National Institute for Health Research. The findings are being published in the May issue of Diabetes, the journal of the American Association of Diabetes.
What Are The Symptoms Of Low Blood Pressure
Low blood pressure often has no symptoms, but can sometimes mean that not enough blood is flowing to your brain or organs. This can cause symptoms such as:
- feeling dizzy, faint or light-headed
- feeling unsteady
- suddenly noticing your heartbeat
If you have these symptoms, stop what youre doing and sit down or lie down in case you fall, and drink some water.
Speak to your doctor or nurse if you experience these symptoms. As well as being unpleasant, they could mean youre at risk of having a fall. They could also be a sign of another health problem.

Digestive Endocrine And Circulatory Systems
After you eat, your digestive system breaks down carbohydrates and turns them into glucose. Essentially, glucose is your bodys fuel source.
As your sugar levels rise, your pancreas releases a hormone called insulin, which helps glucose get taken up and used by cells throughout your body. If you have insulin-dependent diabetes, you must take the right about of insulin to get the job done.
Any excess glucose goes to your liver for storage.
When you go a few hours without eating, blood sugar levels go down. If you have a healthy pancreas, it releases a hormone called glucagon to make up for the absence of food. This hormone tells your liver to process the stored sugars and release them into your bloodstream.
If everything works as it should, your blood sugar levels should remain in the normal range until your next meal.
Insufficient blood sugar levels can cause a rapid heartbeat and heart palpitations. However, even if you have diabetes, you may not always have obvious symptoms of low blood sugar. This is a potentially dangerous condition called hypoglycemia unawareness. It happens when you experience low blood sugar so often that it changes your bodys response to it.
Normally, low blood sugar causes your body to release stress hormones, such as epinephrine. Epinephrine is responsible for those early warning signs, like hunger and shakiness.
When To Contact A Medical Professional
If low blood pressure causes a person to pass out , seek treatment right away. Or call 911 or the local emergency number. If the person is not breathing or has no pulse, begin CPR.

Hypoglycemia In Children: Pediatric Ketotic Hypoglycemia
Some children experience pediatric ketotic hypoglycemia, a condition involving low blood sugar levels and high levels of ketones. If people do not have enough glucose to use as energy, the body begins to break down fat in the body instead. The body produces chemicals called ketones as a by-product of breaking down fat.
According to a 2019 study , pediatric ketotic hypoglycemia usually occurs due to poor intake of food, a gastrointestinal illness and vomiting, or a period of prolonged fasting. Severe metabolic and hormonal conditions may also cause pediatric ketotic hypoglycemia.
Pediatric ketotic hypoglycemia may affect children from 6 months old and often resolves after the age of 6 years.
The Dangers Of Low Blood Glucose
At some time, most people with diabetes experience the sweating and shakiness that occurs when blood glucose levels fall below 70 mg/dl a condition known as hypoglycemia. The average person with type 1 diabetes may experience symptoms of low blood glucose up to two times a week. However, not all are aware that these symptoms can rapidly progress to seizures, coma and even death if hypoglycemia is severe. Though hypoglycemia can be common and occur repeatedly in some people with diabetes, symptoms of low blood glucose should always be taken seriously. People with diabetes and their families, friends or coworkers should be prepared to act quickly and responsibly at the earliest signs of low blood glucose.

Risks Of Hypoglycemia In Critical Illness
In a large multicenter randomized controlled trial in Australia , the relationship of glycemic control to outcome from critical illness was examined in patients being treated in intensive care units. Strict control of blood glucose was compared with standard control . Mortality was higher in patients who maintained strict glycemic control, in whom severe hypoglycemia was much more common . A subgroup analysis suggested that no difference in 90-day mortality existed between individuals with diabetes and individuals without diabetes . Potential weaknesses of this study limit interpretation. Unfortunately, the protocol permitted a reduction in the frequency of blood glucose measurements to four hourly tests when blood glucose was considered to be stable, which was then inadequate to assess glycemic control. In addition, neuroglycopenia may be more difficult to detect in an unconscious patient under sedation and may not therefore be identified. Two meta-analyses have shown that strict glycemic control in seriously ill patients does not improve overall survival but reduces the risk of septicemia in surgical intensive care units at the expense of a fivefold higher incidence of hypoglycemia .
How Is Bradycardia Treated
You may not need any treatment. Bradycardia is usually treated if it causes symptoms, such as dizziness or fainting. The cause of your bradycardia may need to be treated. For example, you may need treatment for sleep apnea if this is causing your symptoms. Your healthcare provider will talk with you about the benefits and risks of treatment that may be right for you:
- Heart medicines may be given to increase your heart rate. These medicines are given through an IV.
- A temporary pacemaker is a short-term treatment in the hospital. The pacemaker is applied to your skin with sticky pads or placed into a vein in your neck or chest. A small pacing device helps keep your heartbeat stable.
- A permanent pacemaker is implanted under the skin of your chest or abdomen during surgery. A tiny battery creates electrical impulses that keep your heart rate regular.

Mild hypoglycemia can cause such symptoms as:
Severe hypoglycemia can also cause these symptoms:
- not responding or waking up
Teach your child about the symptoms of low blood sugar and what to do. Even young kids who can’t describe their symptoms can learn to tell an adult when they don’t feel well. Help your child understand that they need treatment when they dont feel well. And explain how to find an adult who can help them.
Some people with diabetes can’t sense the early warning signs of low blood sugar. They may not recognize they need quick treatment. This can lead to more serious symptoms as blood sugar levels continue to fall. If you think your child cant sense what low blood sugar feels like, tell the diabetes care team.

Be Aware Take Control
Those affected by all types of diabetes are still at risk of developing heart disease, even if blood sugar levels are managed.
The most common form of heart disease is coronary artery disease, which develops over time as the arteries that supply blood to the heart fill with plaque. Plaque, which is made up of cholesterol and other substances, causes the arteries to harden. The medical term for this is atherosclerosis. When plaque continues to build, the arteries narrow, therefore reducing the flow of oxygen-rich blood to the heart. This causes the heart muscle to weaken, increasing the risk of heart disease, heart attacks, strokes, and even heart failure.

Hypoglycemia As A Potential Risk Factor For Sudden Death In Diabetes
Cumulating clinical and experimental evidence has shown that hypoglycemia can cause abnormal electrical activity in the heart and has strengthened the premise that hypoglycemia can provoke sudden death. High-resolution electrocardiography, which measures the QT interval precisely, in conjunction with hypoglycemic clamps to control the depth of hypoglycemia, has demonstrated lengthening of the QT interval both in diabetic and nondiabetic individuals . Clinical episodes of hypoglycemia have been shown to cause QT lengthening, measured using ambulatory ECG monitoring and simultaneous measurement of blood glucose .
Activation of the sympathoadrenal system probably drives these changes. Epinephrine infusion increases QT intervals , and -blocking drugs attenuate QT lengthening during experimental hypoglycemia . However, hypoglycemia induces a fall in serum potassium via sympathoadrenal activation and a direct effect of insulin, and hypoglycemia per se may have an effect by directly inhibiting cardiac ion channels that are responsible for potassium efflux during cardiac repolarization .

How Your Body Regulates Blood Pressure
A similar set of processes apply to maintaining a healthy blood pressure level. In many ways, keeping your blood pressure in a good range is even more critical than keeping your blood glucose in a good range. Your body has a myriad of ways to make more blood sugar as well as making alternative sources of energy like ketones. But we dont have any way to make more blood pressure. The body can protect blood glucose levels much better than it can protect blood pressure. If we are experiencinglow blood volume, we cant add more instantly. If we dont have enough blood, we will pass out and this is very dangerous to the brain and body long term.
With limited options for raising blood pressure, the body relies on the same hormones that get activated when blood glucose is lowcatecholamine, or adrenalin, hormonesto affect this change. Catecholamines tighten up our blood vessels, making it harder for the heart to pump the blood through our arteries, which raises blood pressure.
People with, a condition in which blood pressure is elevated, dont lack the ability to control their blood pressure. But like the person with diabetes, their sensors are impaired and their response to high or low blood pressure isnt always on the mark.

Nighttime Low Blood Sugar
While low blood sugar can happen at any time during the day, some people may experience low blood sugar while they sleep. Reasons this may happen include:
- Having an active day.
- Being physically active close to bedtime.
- Taking too much insulin.
- Drinking alcohol at night.
Eating regular meals and not skipping them can help you avoid nighttime low blood sugar. Eating when you drink alcohol can also help. If you think youre at risk for low blood sugar overnight, have a snack before bed.
You may wake up when you have low blood sugar, but you shouldnt rely on that. A continuous glucose monitor can alert you with an alarm if your blood sugar gets low while youre sleeping.

When Your Blood Sugar Gets Low
Check your blood sugar whenever you have symptoms of low blood sugar. If your blood sugar is below 70 mg/dL, treat yourself right away.
1. Eat something that has about 15 grams of carbohydrates. Examples are:
- 3 glucose tablets
- One half cup of fruit juice or regular, non-diet soda
- 5 or 6 hard candies
- 1 tablespoon or 15 mL of sugar, plain or dissolved in water
- 1 tbsp of honey or syrup
2. Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain.
3. Check your blood sugar again.
4. If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL , eat another snack with 15 g of carbohydrates.
You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range — over 70 mg/dL — and your next meal is more than an hour away.
Ask your provider how to manage this situation. If these steps for raising your blood sugar do not work, call your doctor right away.
