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.
What Else Can You Do To Control Blood Sugar Levels
Yes. People with diabetes should wear identification stating they have diabetes and whether they have recurrent low blood sugar. Those at risk for the health condition should be counseled on checking blood sugars before they drive a car, operate heavy machinery, or do anything physically taxing. In addition, it is important to carry a quick-acting glucose source at all times, and keep a source in their car, office, and by their bedside. Efforts should be made to minimize the hypoglycemic effects of drug regimens and to avoid variable surges in exercise, activity, and drinking alcohol.
What Are The Symptoms Of Hypoglycemia
Symptoms of hypoglycemia can start quickly, with people experiencing them in different ways. The signs of hypoglycemia are unpleasant. But they provide good warnings that you should take action before blood sugar drops more. The signs include:
- Shaking or trembling.
- Tingling or numbness in the face or mouth.
During a severe hypoglycemic event, a person may:
- Be unable to eat or drink.

Symptoms Of Low Blood Sugar
How you react to low blood sugar may not be the same as how someone else with low blood sugar reacts. Its important to know your signs. Common symptoms may include:
- Fast heartbeat
If youve had low blood sugar without feeling or noticing symptoms , you may need to check your blood sugar more often to see if its low and treat it. Driving with low blood sugar can be dangerous, so be sure to check your blood sugar before you get behind the wheel.
You may not have any symptoms when your blood sugar is low . If you dont have symptoms, it will be harder to treat your low blood sugar early. This increases your risk of having severe lows and can be dangerous. This is more likely to happen if you:
- Have had diabetes for more than 5-10 years.
- Frequently have low blood sugar.
- Take certain medicines, such as beta blockers for high blood pressure.
If you meet one or more of the above and you have hypoglycemia unawareness, you may need to check your blood sugar more often to see if its low. This is very important to do before driving or being physically active.

The Causes Of Low Blood Sugar
Low blood sugar levels can happen to kids with diabetes because of the medicines they have to take. Kids with diabetes may need a hormone called insulin and/or diabetes pills to help their bodies use the sugar in their blood. These medicines help take the sugar out of the blood and get it into the body’s cells, which makes the level of sugar in the blood go down.
But sometimes it’s a tricky balancing act, and blood sugar levels can get too low. Kids with diabetes need to keep their blood sugar levels from getting too high or too low. How do they do it? With help from grown-ups, they keep three things in balance:
Each one of these can affect the other. For instance, eating more might mean a kid needs more insulin. And exercising might create the need for an extra snack. Again, a grown-up can help you learn how to juggle those three activities so you keep feeling good.
Some things that can make low blood sugar levels more likely to happen are:
- skipping meals and snacks
- not eating enough food at a meal or snack
- exercising longer or harder than usual without eating something extra
- getting too much insulin
- not timing the insulin doses properly with meals, snacks, and exercise
- taking a long bath or shower right after an insulin shot
What Is Low Blood Sugar
You may have briefly felt the effects of low blood sugar when you’ve gotten really hungry or exercised hard without eating enough. This happens to nearly everyone from time to time. It’s easy to correct and usually nothing to worry about.
But low blood sugar, or hypoglycemia, can also be an ongoing problem. It occurs when the level of sugar in your blood drops too low to give your body energy.

If A Person Is Unconscious
If a person loses consciousness because of severe hypoglycaemia, they need to be put into the recovery position and given an injection of the hormone glucagon . The injection will raise their blood glucose level.
The injection should be carried out by a friend or family member who knows what they’re doing, or by a trained healthcare professional.
You should dial 999 to request an ambulance if:
- a glucagon injection kit isn’t available
- there’s nobody available who’s trained to give the injection
- the injection is ineffective after 10 minutes
Never try to put food or drink into the mouth of someone who’s unconscious as they could choke.
If you’re able to give a glucagon injection and the person regains consciousness, they should eat some longer-acting carbohydrate food, such as a few biscuits, a cereal bar or a sandwich.
You should continue to monitor the person for signs of recurring symptoms in case they need to be treated again.

- conditions that lead to excess production of certain hormones
Symptoms usually appear after the age of 6 months and disappear before adolescence.
- mood changes
- clumsy or jerky movements

Check Your Blood Sugar Often
Talk with your provider about when you should check your blood sugar every day. People who have low blood sugar need to check their blood sugar more often.
The most common causes of low blood sugar are:
- Taking your insulin or diabetes medicine at the wrong time
- Taking too much insulin or diabetes medicine
- Taking insulin to correct high blood sugar without eating any food
- Not eating enough during meals or snacks after you have taken insulin or diabetes medicine
- Skipping meals
- Waiting too long after taking your medicine to eat your meals
- Exercising a lot or at a time that is unusual for you
- Not checking your blood sugar or not adjusting your insulin dose before exercising
- Drinking alcohol
What Causes Low Blood Glucose
- Symptoms occur when blood glucose levels fall below 70 mg/dl a condition known as hypoglycemia.
- In most cases, low blood glucose results from overtreatment: Either taking too much diabetes medication or not eating enough food. Higher doses of medicine than the person actually requires can also lead to hypoglycemia.
- People who aim for too-low values on their A1C test tend to experience more frequent drops in blood glucose.
- Vigorous exercise doesn’t just burn calories, it also burns blood glucose! Hypoglycemia can occur unless blood glucose levels are carefully monitored during and after exercise.
- Not eating on a regular basis can deprive the body of glucose and make it difficult to prevent hypoglycemia. Eat balanced meals throughout the day and always keep a snack on hand.

Signs Of Hypoglycemic Unawareness
Some people have no symptoms of low blood sugar. The only symptom you may have is confusion. Or you may become unconscious before anyone realizes you have low blood sugar.
You may have hypoglycemic unawareness if you:
- Cannot tell by your symptoms that your blood sugar is low.
- Have low blood sugar several times a week.
- Have type 1 diabetes, or have had type 2 diabetes for a long time.
If you have hypoglycemic unawareness, test your blood sugar often, especially before activities like driving a car. Keep some glucose or sucrose tablets or solution or quick-sugar foods with you. If you take insulin, carry a glucagon emergency kit. You can also give friends and family instructions to treat low blood sugar.
Checking For Low Blood Sugar Levels
The warning signs of hypoglycemia are the body’s natural response to low blood sugar levels. When blood sugar levels fall too low, the body releases the hormone adrenaline, which helps get stored glucose into the bloodstream quickly. This can make someone:
- start shaking
- have an increased heart rate
If the hypoglycemia isn’t treated, more serious symptoms may happen, such as drowsiness, confusion, seizures, and loss of consciousness.
The only way to know for sure if you’re having a low blood sugar level is to test. Blood sugar levels can be tested with a . This computerized device measures and displays the amount of glucose in a blood sample. But if you can’t quickly check your blood sugar level, it’s important to treat yourself for hypoglycemia immediately to prevent symptoms from getting worse.
Sometimes a person with diabetes may have symptoms of low blood sugar levels, but blood sugar levels are not actually low. This is a called a false reaction. The hormone adrenaline is not just released when blood sugar drops too low it’s also released when blood sugar levels fall quickly when they’re too high. If you’re having a false reaction, you might actually have blood sugar levels in a healthy range but feel as if you have low blood sugar. Testing blood sugar levels before treating yourself for hypoglycemia can help you figure out if you’re having a false reaction.

Overdose Of Diabetes Medication
A common cause of hypoglycaemia is taking too much insulin for your current needs. Insulin is a medication that helps control your blood glucose levels. It’s commonly used to treat type 1 diabetes and is also recommended for some people with type 2 diabetes.
A fall in blood glucose levels can also occur after taking too much oral hypoglycaemia medication, such as sulphonylurea, which causes a release of insulin. This medication is often used to lower blood glucose levels in people with type 2 diabetes.
What If Im Experiencing Hypoglycemic Episodes Even Though My Doctor Has Confirmed That Im Not Diabetic Or Prediabetic
If you have low blood sugar and dont have diabetes or prediabetes, it can be a sign of another serious health issue such as a tumor, hormone deficiency, kidney disorder, anorexia, or other eating disorder, all of which can cause dangerously low blood sugar.
Anorexia has the highest mortality of any psychiatric disorder, and the cause of death can be hypoglycemia, so take your illness seriously and seek help if you suspect your eating disorder may be progressing to the point where it is causing you to faint or experience other signs and symptoms of dangerously low blood sugar. The National Eating Disorders Association has resources on how to identify the signs that you may have an eating disorder, a hotline for help, as well as easily accessible information on everything from how to know when you need help to how to find quality treatment options in your zip code.
People who are not diabetic don’t spontaneously have hypoglycemia for no reason, explains Dr. Christofides. Its often an indication of another underlying issue, such as a hormone deficiency or eating disorder, so its important to schedule an appointment with your doctor to determine the cause in order to prevent complications.
Common causes of hypoglycemia in people without diabetes include:
- Pancreatic tumor
- Medication that inhibits the proper production of insulin
- Hepatitis or kidney disorders
- Hormone deficiencies
- Anorexia and other eating disorders
