How Can You Tell If You Have Low Blood Sugar

Preventing Low Blood Sugar

Preventing low blood sugar is better than having to treat it. Always have a source of fast-acting sugar with you.

• When you exercise, check your blood sugar levels. Make sure you have snacks with you.
• Talk to your provider about reducing insulin doses on days that you exercise.
• Ask your provider if you need a bedtime snack to prevent low blood sugar overnight. Protein snacks may be best.

DO NOT drink alcohol without eating food. Women should limit alcohol to 1 drink a day and men should limit alcohol to 2 drinks a day. Family and friends should know how to help. They should know:

• The symptoms of low blood sugar and how to tell if you have them.
• How much and what kind of food they should give you.
• When to call for emergency help.
• How to inject glucagon, a hormone that increases your blood sugar. Your provider will tell you when to use this medicine.

If you have diabetes, always wear a medical alert bracelet or necklace. This helps emergency medical workers know you have diabetes.

How To Treat Low Blood Sugar

If you think you have low blood sugar, be sure to check it.

Keeping your blood sugar levels on target as much as possible can help prevent or delay long-term, serious health problems. While this is important, closely managing your blood sugar levels also increases your chance for low blood sugar . Blood sugar below 70 mg/dL is considered low. If you think you have low blood sugar, check it. If you arent able to check it, go ahead and treat it.

Untreated low blood sugar can be dangerous, so its important to know what to do about it and to treat it immediately.

How Common Is Low Blood Glucose

Low blood glucose is common among people with type 1 diabetes and among people with type 2 diabetes who take insulin or some other diabetes medicines. In a large global study of people with diabetes who take insulin, 4 in 5 people with type 1 diabetes and nearly half of those with type 2 diabetes reported a low blood sugar event at least once over a 4-week period.2

Severely low blood glucose, defined as when your blood glucose level drops so low you cant treat it yourself, is less common. Among U.S. adults with diabetes who take insulin or some diabetes medicines that help the pancreas release insulin into the blood, 2 in 100 may develop severely low blood glucose each year.3

What To Do If You Have Low Blood Sugar Symptoms

If you have diabetes and are experiencing mild to moderate hypoglycemia symptoms, you need to immediately eat or drink 15 grams of easily digestible carbohydrates.

Very low blood sugar is a medical emergency. If you or someone else with diabetes is experiencing severe symptoms, such as unconsciousness, its important to administer a medication called glucagon and contact emergency services immediately.

If youre at risk for low blood sugar, its important to talk with your doctor about getting a prescription for glucagon.

You should never give an unconscious person anything by mouth, as it could cause them to choke. If you have diabetes, make sure your family and friends know not to do this if you lose consciousness.

Low blood sugar can occur for a number of reasons. Its usually a side effect of diabetes treatment.

S For Treating A Person With Symptoms Keeping Them From Being Able To Treat Themselves

Dont hesitate to call 911. If someone is unconscious and glucagon is not available or someone does not know how to use it, call 911 immediately.

Do NOT:

• Inject insulin
• Provide food or fluids

How Do I Treat An Episode Of Hypoglycemia

The American Diabetes Association recommends the 15-15 rule for an episode of hypoglycemia:

• Eat or drink 15 grams of carbs to raise your blood sugar.
• After 15 minutes, check your blood sugar.
• If its still below 70 mg/dL, have another 15 grams of carbs.
• Repeat until your blood sugar is at least 70 mg/dL.

If you have symptoms of hypoglycemia but cant test your blood sugar, use the 15-15 rule until you feel better.

Note: Children need fewer grams of carbs. Check with your healthcare provider.

What Are Clinical Trials For Low Blood Glucose

Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of low blood glucose levels in diabetes, such as

• how to diagnose and treat low blood glucose among people with diabetes
• medicines that can treat symptoms of low blood glucose in people with hypoglycemia unawareness
• educational approaches to reduce fear of low blood glucose, which can make it harder for you to control your diabetes

Symptoms Of Mild Low Blood Sugar

You may have these symptoms when your blood sugar has dropped below 70 milligrams per deciliter . When you have had diabetes for many years, you may not always develop symptoms of mild low blood sugar.

Some young children with diabetes cannot recognize symptoms of low blood sugar. Others can, but not every time. To be safe, the parents need to do a home blood sugar test whenever they suspect low blood sugar in a child.

Symptoms may include:

• Sweating . Check for sweating on the back of your neck at your hairline.
• Nervousness, shakiness, and weakness.
• Extreme hunger and slight nausea.
• Dizziness and headache.
• A fast heartbeat and feeling anxious.

These symptoms may go away shortly after you eat food that contains sugar.

About High Blood Sugar

High glucose levels occur when the body doesn’t have enough insulin or can’t properly use the insulin it has to shuttle glucose from the bloodstream to the bodys muscles, organs, and tissues for fuel, ONeill says. As a result, the amount of sugar in the blood builds up.

Hyperglycemia typically happens when you consume more carbohydrates or bigger portions of food than usual if you don’t take enough insulin or other diabetes medication as prescribed and if you decrease your levels of physical activity, she says. Heightened stress levels can also increase blood sugar levels. Non-diabetes-related medications that are known to raise blood sugar levels include steroids, beta-blockers, birth control pills, and many mental health medications, she explains.

Signs of high blood sugar include frequent urination, fatigue, dry or itchy skin, feeling thirsty, more frequent infections, and eating more food but not gaining as much weight as usual, says Athena Philis-Tsimikas, MD, the corporate vice president for the Scripps Whittier Diabetes Institute in La Jolla, California.

High blood sugar levels can cause these symptoms through various mechanisms, according to the Mayo Clinic. For example, high blood sugar levels damage blood vessels and nerves throughout the body. They can also deprive organs of energy and can cause fluid to accumulate in the eyes. And in an attempt to get your blood sugar to a healthier level, your body will often increase urine output.

What If I Have Severe Low Blood Glucose And Cant Treat Myself

Glucagona hormone that raises blood glucose levelsis the best way to treat severely low blood glucose. Available as an injection or a nasal spray, glucagon will quickly raise your blood glucose level. Your doctor can prescribe you a glucagon kit for use in case of an emergency.

If your blood glucose level drops very low, you wont be able to treat it by yourself. Be prepared to address severely low blood glucose by

• talking with your doctor or health care team about when and how to use a glucagon emergency kit. If you have an emergency kit, regularly check the date on the package to make sure it hasnt expired.
• teaching your family, friends, and coworkers when and how to give you glucagon. Tell them to call 911 right away after giving you glucagon or if you dont have a glucagon emergency kit with you.
• wearing a medical alert identification bracelet or pendant. A medical alert ID tells other people that you have diabetes and need care right away. Getting prompt care can help prevent the serious problems that low blood glucose levels can cause.

Examples Of Appropriate Snacks May Be:

• 6 saltine crackers
• 1 slice toast and 1/2 cup milk
• 1 cup milk

The food eaten for a reaction need not be subtracted from a meal plan.

Obtain a blood sugar when symptoms occur if you are able. If symptoms are severe, treat the reaction first and then obtain a blood sugar. Do not drive nor operate equipment if you feel your blood sugar is low.

If your blood sugar drops low enough for you to become unconscious, you must be taken to the hospital and/or treated with glucagon.

Glucagon is a hormone that causes the blood sugar to rise. It can only be given by injection. It is used to treat a low blood sugar if a person becomes semi-conscious or unconscious due to a severe low blood sugar. Please ask your nurse for instruction on glucagon. Your doctor will need to write a prescription for glucagon so you can have it available at home.

Signs Of Low Blood Sugar

With hypoglycemia, the blood sugar falls below the normal, healthy levels mentioned earlier, which can occur for a variety of reasons.

“Although some people with blood sugar problems may not experience symptoms,” Dr. Aldasouqi continued, “there are some key things to look out for. For those with low blood sugar, someone might have symptoms like anxiety, sweating, increased heart rate, confusion, and may go into what is called ‘a hypoglycemic coma’… The term ‘diabetic coma’ is also used by some.”

Other symptoms of low blood sugar may include:

• Fatigue
• Tingling or numb lips, tongue or cheek
• Blurry vision

Possible Causes Without Diabetes

Even if you dont have diabetes, you may experience low blood sugar. However, hypoglycemia is much less common in people without diabetes.

Some possible causes of low blood sugar in people who dont have diabetes are:

• certain medications, such as quinine
• some medical conditions, such as hepatitis and kidney disorders
• a tumor that produces excess insulin
• endocrine disorders, such as adrenal gland deficiency

Prevention Of Low Blood Sugar

Do not skip or delay meals. If your diet plan includes snacks, make sure to take these.

Measure insulin dosage carefully and inject it properly. If you cannot see well, a family member or a visiting nurse can prepare your insulin injections for you.

Take only the prescribed amount of insulin or oral medication for diabetes that your doctor has ordered.

Keep exercise consistent from day to day. Eat a snack or reduce your insulin prior to unusual exercise.

If you are taking insulin, notify your doctor if you have low blood sugars four or more times per week or if you have a severe low blood sugar. Severe low blood sugars are those less than 40 mg., those requiring help from another person, or those which cause you to have a convulsion or become unconscious.

If you are taking oral medication for your diabetes notify your doctor or nurse if blood sugars are running less than 80 mg. or if you have a severe low blood sugar.

What Is Blood Sugar

Blood sugar, or glucose, is your body’s main energy source. We get glucose from the food we eat, and our blood carries it around to all the cells in the body to give them energy to function. Glucose mainly comes from the carbohydrates we eat, though our bodies can convert protein and fat into sugar too if needed.

Glucose from protein is typically stored in the liver and doesn’t enter the bloodstream, so eating protein-rich foods won’t raise your blood sugar too much. Fats slow down the digestion of carbohydrates, which causes a delayed rise in blood sugar. High blood sugar can be an issue because it usually leads to sugar crashes, which are no fun — symptoms include fatigue, headaches and the jitters. So, eat meals balanced with protein, fat and carbs to avoid this.

Blood sugar is closely related to insulin, a hormone secreted by the pancreas that helps your body use glucose that’s in the carbohydrates you eat. Insulin helps regulate your blood sugar levels — if you eat more sugar than you need in the moment, the hormone helps store the glucose in your liver until it’s needed for energy.

You probably also know about blood sugar in the context of diabetes. Type 1 diabetes is a condition in which people are unable to make insulin, so they need to inject the hormone in order to keep their blood sugar levels stable. People with Type 2 diabetes, which usually occurs later in life, either don’t secrete insulin or are resistant to it.

What Is The Outlook For People With Hypoglycemia

Hypoglycemia can be managed when you and your healthcare provider understand what causes your blood sugar to go down. Give your healthcare provider as much information as possible about any hypoglycemic episodes. Fixing the problem may be as simple as changing the times you take medication, eat and exercise. Minor changes to the types of food you eat may also help.

How Can I Tell If My Blood Sugar Is Irregular

Again, only a doctor can diagnose a problem with your blood sugar. But you may be wondering how to know if it’s something you should get checked out. There can be two main issues with your blood sugar — either it’s consistently too high or too low. Even if you don’t have diabetes, there are some signs that your blood sugar levels are not functioning normally.

Hypoglycemia is a condition in which your blood sugar is too low. Signs include an irregular heartbeat, fatigue, shakiness and tingling or numbness in your face. If you consistently feel this way when you get hungry or between meals, talk to your healthcare provider.

On the flipside, hyperglycemia happens when your blood sugar is too high, and can happen to nondiabetics. Symptoms include frequent urination, increased thirst and headache. If you think you’re hyperglycemic and can’t keep fluids or food down, call for emergency medical assistance.

Preventing A Low Blood Sugar Level

If you have diabetes, you can reduce your chance of getting a low blood sugar level if you:

• Check your blood sugar level regularly and be aware of the symptoms of a low blood sugar level so you can treat it quickly.
• Always carry a sugary snack or drink with you, such as glucose tablets, a carton of fruit juice or some sweets. If you have a glucagon injection kit, always keep it with you.
• Do not skip meals.
• Be careful when drinking alcohol. Do not drink large amounts, check your blood sugar level regularly, and eat a carbohydrate snack afterwards.
• Be careful when exercising eating a carbohydrate snack before exercise can help to reduce the risk of a hypo. If you take some types of diabetes medicine, your doctor may recommend you take a lower dose before or after doing intense exercise.
• Have a carbohydrate snack, such as toast, if your blood sugar level drops too low while you’re asleep

If you keep getting a low blood sugar level, talk to your diabetes care team about things you can do to help prevent it.

What Is Normal Blood Sugar

When we eat, glucose — which is our body’s main source of energy — enters our bloodstream from our food. Then our pancreas secretes a hormone called insulin in just the right amount to help the glucose go from the bloodstream to our body’s various cells to be used as energy. This process usually keeps the glucose in our bloodstream in a healthy range, being neither too high, nor too low.

This range is measured in milligrams of blood glucose per deciliter, or mg/dL. Dr. Saleh Aldasouqi, Chief of Endocrinology at Michigan State University, explains to CNET: “Normal blood sugar is defined as anywhere from 70 to 110 mg/dL within a healthy physiology, as a person without diabetes or other related diagnosed condition. Sugar below 70 is generally considered low, and above 110 is considered high .”

What If The 15

If you dont feel better after three tries, or if your symptoms get worse, call your healthcare provider or 911. Healthcare providers can use a medication called glucagon. They inject it with a needle or squirt it up your nose. Glucagon is also available for home use. Your healthcare provider can prescribe it and teach a family member or friend how to use it in the event of severe hypoglycemia.
