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
How Can I Prevent Low Blood Sugar
Your best bet is to practice good diabetes management and learn to detect hypoglycemia so you can treat it earlybefore it gets worse.
Monitoring blood sugar, with either a meter or a CGM, is the tried and true method for preventing hypoglycemia. Studies consistently show that the more a person checks blood sugar, the lower his or her risk of hypoglycemia. This is because you can see when blood sugar levels are dropping and can treat it before it gets too low.
If you can, check often!;;
- Check before and after meals.
- Check before and after exercise .
- Check before bed.
- After intense exercise, also check in the middle of the night.
- Check more if things around you change such as, a new insulin routine, a different work schedule, an increase in physical activity, or travel across time zones.
What Causes Low Blood Sugar
Despite advances in the treatment of diabetes, low blood sugar episodes occur as a side effect of many treatments for diabetes. In fact, these episodes are often the limiting factor in achieving optimal blood sugar control, because many medications that are effective in treating diabetes carry the risk of lowering the blood sugar level too much, causing symptoms. In large scale studies looking at tight control in both type 1 and type 2 diabetes, low blood sugars occurred more often in the patients who were managed most intensively. This is important for patients and physicians to recognize, especially as the goal for treating patients with diabetes becomes tighter control of blood sugar.
While people who do not have any metabolic problems can complain of symptoms that resemble low blood sugar, true hypoglycemia usually occurs in people with diabetes mellitus . People with pre-diabetes or insulin resistance also can have low blood sugars on occasion if their high circulating insulin levels are further challenged by a prolonged period of fasting. There are other rare causes for the condition, such as insulin-producing tumors and certain medications.
These uncommon causes of hypoglycemia will not be discussed in this article, which will primarily focus on the condition occurring with type 1 or 2 diabetes and its treatment.

Why Is It Important To Recognize A Low Blood Sugar Level
Low blood sugar levels can happen with Type 1 and Type 2 diabetes. Low levels are more likely to happen if you use insulin. Hypoglycemia can cause you to have falls, accidents, and injuries. A blood sugar level that gets too low can lead to seizures, coma, and death. Learn to recognize the symptoms early so you can get treatment quickly.
What To Do When Your Blood Sugar Levels Drop Too Low
People who use insulin and other diabetes medications are at risk for hypoglycemia. Keep this action plan handy so you’re prepared.
If you take insulin or diabetes medication, you may be at risk of developing hypoglycemia, or low blood sugar. Without quick attention, hypoglycemia can lead to serious complications, so its important to know what to do if it happens to you or someone close to you.
In very severe cases, hypoglycemia can lead to seizures or loss of consciousness, says;;a clinical assistant professor of medicine, endocrinology, gerontology, and metabolism at Stanford Health Care, and chief of the Stanford Endocrine Clinic.
It’s possible to have hypoglycemia but have no symptoms, according to the National Institute of Diabetes and Digestive and Kidney Diseases . On the other hand, symptoms can also come on rapidly. While symptoms vary from person to person, if you develop mild to moderate low;blood sugar;you may:
- Feel shaky or jittery
- Have a headache or be lightheaded
- Turn pale
- Be irritable or combative
- Have blurred vision or see double
Some people feel tingling or numbness in their extremities too, says Rodolfo Galindo, MD, an assistant professor of medicine in the division of endocrinology, metabolism, and lipids at the Emory University School of Medicine in Atlanta, and chair of the inpatient diabetes taskforce.

Causes Of Low Blood Sugar
Low blood sugar is common for people with type 1 diabetes and can occur in people with;type 2 diabetes;taking insulin or certain medications. The average person with;type 1 diabetes;may experience up to two episodes of mild low blood sugar each week, and thats only counting episodes with symptoms. If you add in lows without symptoms and the ones that happen overnight, the number would likely be higher.
Act Rapidly To Treat The State Of Affairs
If you believe you studied you might have low blood sugar, Dr. Fruge recommends rapidly treating the state of affairs, which she says ought to embody eating healthy foods such as complex carbohydrates, beans or fruit.;
At the Pritikin Longevity Center we serve a cup of fruit with a cup of veggies to prevent a spike in insulin, which can sometimes lead to a later drop in blood sugar again, she explains. Adjusting your diabetes medication as prescribed by your physician may also be necessary. Its important to retest your blood sugar 20 minutes after eating to confirm it has improved.
Keep a fast-acting carbohydrate snack or two available in case your blood sugar dips beneath wholesome ranges.

Whats The Link Between Diabetes And Hypoglycemia
Hypoglycemia is most common, by far, in people with diabetes. Treatment for the diseaseoften involves taking medication to increase insulin. Hypoglycemia can develop if things like food, exercise and diabetes medications are out of balance.
Common pitfalls for people with diabetes include:
- Being more active than usual.
- Drinking alcohol without eating.
- Eating late or skipping meals.
- Not balancing meals by including fat, protein and fiber.
- Not eating enough carbohydrates.
- Not timing insulin and carb intake correctly .
Also, if someone with diabetes uses the wrong insulin, takes too much or injects it incorrectly, that can cause hypoglycemia.
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 .”

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.
Nighttime Low Blood Sugars
You may experience a low blood sugar night. The low blood sugar might wake you up and your symptoms might be similar to those you have during the day. However, the symptoms may be different. You might have nightmares, sleep poorly, perspire, or feel hot and cold. In the morning you may have a headache, feel nauseated, or feel confused. Notify your doctor if this happens. Check your blood sugar at the time you have the symptoms.
Treatment for a low blood sugar that occurs at night is the same as described earlier.
Your doctor may request that you check a 3:00 a.m. blood sugar 1 to 2 times per week in order to detect any low blood sugars during the night.

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.
Talk To Your Doctor Or Nurse
If you use insulin and your blood sugar is frequently or consistently low, ask your doctor or nurse if you:
- Are injecting your insulin the right way
- Need a different type of needle
- Should change how much insulin you take
- Should change the kind of insulin you take
DO NOT make any changes without talking to your doctor or nurse first.
Sometimes hypoglycemia can be due to taking the wrong medicines. Check your medicines with your pharmacist.

Treating Low Blood Sugar
You are at risk of having a low blood sugar reaction if you:
- Skip or delay a meal or snack
- Take too much insulin or eat too few carbohydrates
- Drink alcohol, especially without eating carbohydrates
Check your blood sugar if you have any of these symptoms:
- Weakness and/or fatigue
If your blood sugar is less than 70 milligrams per deciliter :
- Eat 15 to 30 grams of carbohydrate
- Wait 15 minutes and then recheck your blood sugar
- If your blood sugar is still less than 100 mg/dl, take another 15 grams of carbohydrate and retest your blood sugar in another 15 minutes. Repeat if necessary.
Important: If you have frequent low blood sugars speak to your doctor. You may need changes in your medication and/or meal plan.
What Foods Can Help Raise Blood Sugar Fast
Because your blood sugar comes from the foods and beverages you consume, one of the easiest ways to raise your blood sugar fast is to grab a quick snack.
The American Diabetes Association recommends the 15-15 rule if your blood sugar dips below 70 mg/dL: Eat at least 15 grams of carbohydrates, then wait 15 minutes to recheck your blood sugar.
If youre still below 70 mg/dL, have another 15 grams of carbs, wait 15 minutes, and check your levels again.
Among the foods you can try for a quick blood sugar boost are:
- a piece of fruit, like a banana, apple, or orange
- 2 tablespoons of raisins
- 4 Starbursts
- 1 tablespoon of sugar in water
Foods that contain protein or fat, such as peanut butter, ice cream, and chocolate, may be helpful if your blood sugar level has dropped but isnt below 70 mg/dL.
These higher-fat foods, as well as whole-grain bread and other high-fiber foods, take longer to absorb into your bloodstream. Because of this, these foods wont raise your blood sugar as quickly as foods that have more simple carbohydrates.

Do Not Drive When You Have Low Blood Sugar
It’s very dangerous. If you’re driving and you have hypoglycemia symptoms, pull off the road, check your blood sugar, and eat a sugary food. Wait at least 15 minutes, check your blood sugar, and repeat these steps if necessary. Eat a protein and carbohydrate source before you drive on.
Be prepared. Keep a sugar source in your car at all times for emergencies.
Best Foods For Low Blood Sugar
For patients with diabetes, monitoring blood sugar levels is a part of daily life.
Low blood sugar, or hypoglycemia, can occur for many people with diabetes who are on certain medications, including insulin. It can occur for a variety of reasons including skipping a meal, exercising strenuously, taking too much insulin or consuming alcohol, especially on an empty stomach.
Low blood sugar can be as minor as a slight inconvenience or as serious as a life-threatening emergency. Thats why it is important to boost blood sugar before it becomes problematic.
Angela Norton, a diabetes educator at Sharp Chula Vista Medical Center, has diabetes herself, so she knows firsthand the tips and tricks of keeping blood sugar on track. Although blood glucose is considered normal if above 70 mg/dL, Norton says patients with diabetes should not wait until they reach below that threshold to take action.
Treat when you feel the symptoms, even if your blood sugar is not below 70, because as long as it is less than 100, it may be dropping fast, she says.
When it comes to treatment, Norton shares these five foods to help boost low blood sugar.
1. CandyWhen hypoglycemia occurs, patients should follow the 15-15 rule. Consume 15 grams of carbohydrates to raise blood glucose and check your levels again after 15 minutes. When the numbers return to normal, eat a snack to stay on track.
Gummy candies contain carbohydrates, which have a large impact on blood sugar levels.

No Symptoms Be Alarmed
Surprisingly, the most dangerous episodes of hypoglycemia occur with little or no warning. When low blood glucose occurs on a regular basis, the body can become used to the warning signs and the person may stop noticing symptoms. This is a particularly dangerous condition known as hypoglycemic unawareness. People with this condition might not realize they have low blood glucose until it’s dangerously low seizures and coma are sometimes the first indication of a problem. The good news is that this condition can often be reversed allowing people to once again notice the signs of low blood glucose if hypoglycemia is avoided for a few weeks through careful monitoring of blood glucose.
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.
