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.
A Low Blood Sugar Level Without Diabetes
A low blood sugar level is uncommon in people who do not have diabetes.
Possible causes include:
- a gastric bypass
- other medical conditions, such as problems with your hormone levels, pancreas, liver, kidneys, adrenal glands or heart
- some medicines, including quinine
See a GP if you think you keep getting symptoms of a low blood sugar level. They can arrange some simple tests to check if your blood sugar level is low and try to find out what’s causing it.
When You Have Low Blood Sugar
First, eat or drink 15 grams of a fast-acting carbohydrate, such as:
- Three to four glucose tablets
- One tube of glucose gel
- Four to six pieces of hard candy
- 1/2 cup fruit juice
- 1 cup skim milk
- 1/2 cup soft drink
- 1 tablespoon honey
Fifteen minutes after you’ve eaten a food with sugar in it, check your blood sugar again. If your blood sugar is still less than 70 mg/dL, eat another serving of one of the foods listed above. Repeat these steps until your sugar becomes normal.

Causes For People Without Diabetes
People who do not have diabetes can also experience hypoglycemia symptoms. This can happen because of a variety of medical conditions and lifestyle factors.
Most common are:
- Alcohol consumption. Consuming alcohol causes the body to release more insulin. This leads to an immediate drop in blood sugar that can affect even occasional drinkers.
- Pancreatic tumors. Certain pancreatic tumors can cause your body to produce abnormal amounts of insulin. This leads to chronically low blood sugar levels that can easily dip low enough to cause hypoglycemia symptoms.
- Organ failure. Liver or kidney failure alters the way your body processes the food you eat. This may make you more susceptible to hypoglycemia.
- Infection. Certain infections may trigger metabolic changes that lead to hypoglycemia.
- Hormones. Hormones such as cortisol, adrenaline and glucagon help to regulate blood sugar levels in your body. Imbalanced levels of these hormones may cause hypoglycemia.
- Weight loss surgery. Some people who undergo weight loss surgery experience changes in their metabolism that alter the way their body processes glucose. These people experience an abnormally high spike in glucose levels after eating. This prompts their body to produce too much insulin at once, leading to a rapid drop in blood sugar.
- Medications. Medications like beta-blockers, SGLT2 inhibitors, and indomethacin may cause low blood sugar. Let your doctor know if you experience symptoms of hypoglycemia while taking a new medication.
What Is Considered Low Blood Sugar
For the average person with diabetes, low blood sugar means anything under 80 mg/dL .
Very low blood sugars are any readings under 40 mg/dL. Anything under 40 mg/dL is considered extremely dangerous and potentially fatal.
A person is at a significantly higher risk of falling into a diabetic coma if they cannot get their blood sugar above 40 mg/dL for several hours.
If a person is experiencing a severe low, and they are unable to chew food or swallow liquids, they will require an emergency shot of Glucagon .

What Is The Best Thing To Eat When Your Blood Sugar Is Low
To avoid overtreating lows with too much simple carbohydrate or food and then facing a rebound high blood sugar, its best to have go-to automatic corrections for hypoglycemia that are quantity limited and unappealing to overeat. Glucose tablets and gels, and candies like Smarties, are predictable, relieve low symptoms quickly, and are hard to overeat. Some people with diabetes count out jelly beans, mini-Swedish Fish, gummies, or hard candy and eat the exact amount that will help their blood sugar. Others take a specific amount of juice or another sugar-containing drink.
How do you know how much of your correction to consume? Similar to the 15-15 rule, the only way to discover exactly how much of your go-to correction your body needs is by checking your glucose levels, eating a source of sugar that has been measured out, and then checking again in roughly 15 minutes. This can help you adjust the amount of your source of sugar to raise your blood sugar to your target , but not overshoot. This is a precision dose of carbs.

Do not use a low as a reason to eat treats this can cause your blood sugar to spike later. Plus, it connects a food reward with something you want to avoid , which is an easy way to develop a bad habit.
What Is The Correct Sugar Level After Eating And Temporarily
Consumption of a meal significantly raises blood sugar levels. After eating, an average blood sugar level means that carbohydrate burning is occurring correctly. Glucose levels should drop to about 150 mg/dL after about two hours in a healthy person.
If a glucose measurement taken at any time during the day approaches or exceeds 200 mg/dl, it indicates diabetes. Sugar, after eating, is broken down into glucose, the primary source of energy .
Normal fasting blood sugar levels should be between 70-99 mg/dl in a healthy person. When the concentration is higher but does not exceed
125 mg/dl is glucose intolerance and is only treated with a diet. However, if it exceeds 125 mg/dl, additional tests are recommended to diagnose diabetes.
Blood sugar testing when should it be done?
Blood glucose levels should be tested when :
- when there are symptoms of hypoglycemia or overdiagnosis
- Routinely, as part of laboratory tests especially for people at risk for diabetes
- regularly diabetics measure their sugar several times a day
- Every pregnant woman between 24th and 28th week .
- Every healthy person over 45 should have their fasting blood glucose checked at least once every 3 years. Diabetics test their blood glucose levels at home with a glucometer. To determine their glucose metabolism.

They allow the diagnosis of metabolic diseases and facilitate the application of appropriate therapy. Early detection of changes in the body and proper treatment and prevention is the key to success.
Sugar plays a vital role in the body. It is one of the primary sources of energy for the body belongs to the group of carbohydrates, which in the process of digestion are broken down into simple sugars
Blood glucose level should be more or less at the same level, but if it starts to decrease or exceed the level, your body will stop functioning correctly, which results in various disorders. Insulin, a hormone secreted by the pancreas, maintains sugar levels.
The presence of sugar in the blood is so necessary that without it, our bodies may stop functioning correctly, the nervous system, the skeletal and muscular systems, the lymphatic system, and your organs.
Blood sugar testing is used primarily to diagnose diabetes, but healthy people should also monitor blood glucose levels.

Hypoglycemia Tests And Diagnosis
To diagnose nondiabetic hypoglycemia, your doctor will do a physical exam and ask questions about any medicines you take. Theyâll want to know all about your health and any history of diseases or stomach surgery.
Theyâll check your blood glucose level, especially when you are having symptoms. Theyâll also check to see if you feel better when your sugar goes back to a normal level.
If your doctor suspects hypoglycemia, you may have to fast until you start to have symptoms. Theyâll test your blood glucose level at different times throughout the fast.
To check for reactive hypoglycemia, you may have to take a test called a mixed-meal tolerance test . For this, you take a special drink that raises your blood glucose. The doctor will check your blood glucose levels over the next few hours.
Treating Severely Low Blood Sugar
Blood sugar below 55 mg/dL is considered severely low. You wont be able to treat it using the 15-15 rule. You also may not be able to check your own blood sugar or treat it by yourself, depending on your symptoms. Make sure your family members, friends, and caregivers know your signs of low blood sugar so they can help treat it if needed.
Injectable glucagon is the best way to treat severely low blood sugar. A glucagon kit is available by prescription. Speak with your doctor to see if you should have a kit. Be sure to learn how and when to use it. Let family members and others close to you know where you keep the glucagon kit and make sure theyve been trained in how to use it too.
Its important to contact a doctor for emergency medical treatment immediately after receiving a glucagon injection. If a person faints due to severely low blood sugar, theyll usually wake up within 15 minutes after a glucagon injection. If they dont wake up within 15 minutes after the injection, they should receive one more dose. When the person is awake and able to swallow:
- Feed the person a fast-acting source of sugar .
- Then, have them eat a long-acting source of sugar .
Its also important that friends, family, co-workers, teachers, coaches, and other people you may be around often know how to test your blood sugar and treat severely low blood sugar before it happens.
