What Causes Low Blood Glucose In People With Diabetes
Low blood glucose levels can be a side effect of insulin or some other medicines that help your pancreas release insulin into your blood. Taking these can lower your blood glucose level.
Two types of diabetes pills can cause low blood glucose
- sulfonylureas, usually taken once or twice per day, which increase insulin over several hours
- meglitinides, taken before meals to promote a short-term increase in insulin
The following may also lower your blood glucose level
Your Diabetes Devices And Hypoglycemia
Several insulin pumps are now available that make managing blood sugar levels easier, particularly when connected to a glucose meter or a CGM.
Some of the most important advantages of CGM devices are the improved insulin control and the ability to detect trends and lows early. With improved technology, it is now possible for parents to track blood sugar trends in their kids even when they are hundreds of miles apart .
In addition, automated insulin delivery systems, also known an artificial pancreas or a hybrid closed-loop system, will automatically adjust insulin to match your bodys need to help you spend more time in your target range.
Resources that provide people with T1D and their families with more detailed information about pumps and CGM devices are available through JDRF here. For people looking for a deeper understanding of technology that helps people with T1D better manage their blood sugar, JDRF resources are available here.

What Complications Can Be Caused By Hypoglycemia
Passing out from low blood sugar because you have not recognized the early signs and symptoms is called hypoglycemia unawareness, and can be quite dangerous depending on where you are, explains Dr. Klonoff. As doctors are required to report such incidents to the Department of Motor Vehicles, it can also mean a suspended drivers license.
If this is something youre worried about, Wearing a continuous glucose monitor with an alarm for hypoglycemia can alert a person who is prone to developing low blood sugar levels that their blood glucose concentration is becoming dangerously low, so appropriate preventive action can be taken before they lose consciousness, explains Dr. Klonoff.

How To Help Others Help You
Knowing the signs of low blood sugar, having an action plan, and being prepared with your glucose meter and glucose tablets are vital, but sometimes you might need to rely on other people to help when youre blood sugar drops too low. Take these additional steps so youre prepared and they are, too:
Teach your loved ones. If youre unable to help yourself, friends, family, or colleagues may need to treat you with an injection of glucagon, a hormone that tells your liver to release stored glucose, the American Diabetes Association says. For this reason, its a good idea to teach those close to you what to do. If they dont know how to give you the injection or if glucagon isnt available, they must call 911 and get you the help you need, Evans says. Low blood sugar thats sustained for a prolonged time can lead to irreversible brain damage, according to the University of Maryland Medical Center.
Wear an ID bracelet. Evan suggests that everyone with diabetes should get a tattoo or wear a medical ID bracelet. The bracelet should say diabetes and whether youre on insulin or take other medications, the Joslin Diabetes Center in Boston recommends.
Talk to your doctor about your low blood sugar risk. If you have frequent bouts of hypoglycemia, be sure to talk with your doctor. The solution may be as simple as changing how much or the kind of diabetes medicine you take. However, never make any changes to your medication regimen without your doctors approval.
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.

Effects Of Severe Hypoglycemia
Without emergency treatment, prolonged severe hypoglycemia results in permanent brain damage and irreversible cardiac problems, especially if you already have heart disease. Hypoglycemia causes weakness, tremors, rapid heartbeat and dizziness. Serious injuries can result from loss of consciousness while driving or falling down stairs, according to Joslin Diabetes Center. Drug-induced hypoglycemia is often responsible for falls that cause serious injuries in the elderly who take diabetes medications, such as chlorpropamide, reports the University of Illinois College of Pharmacy. Because many health conditions have similar symptoms, do not ignore recurring symptoms of hypoglycemia, whether mild or severe, as they can be a sign of a serious, undiagnosed medical condition.
What Extreme Conditions Can Occur If Hypoglycemia Is Left Untreated
Although severe episodes which can trigger potentially life-threatening comas are rare, they require immediate emergency room care, so its best to make sure you are tracking your blood sugar so that you never have to worry about getting to that point. A drop in blood sugar means less fuel for your brain, so its critical for your body to receive enough glucose. Hypoglycemia that leads to extended, reduced brain function is the biggest concern, as this can lead to seizures and loss of basic bodily functions controlled by the brain, which can ultimately lead to death, explains Dr. Dyer.

Treating An Episode Of Hypoglycaemia
The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.
For example, this could be:
- a glass of fruit juice or non-diet soft drink
- between three and five dextrose tablets
- a handful of sweets
At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.
After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.
It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.
When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.
It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.
What To Do When Your Blood Sugar Drops
Well, one of the best ways is to eat to get blood sugar up. If you are suffering from diabetes and you think that you have hypoglycemia, it is important to check your blood sugar levels. If you feel that the blood sugar levels drop after you eat a meal, you need to change the diet you are following. You need to avoid taking any foods that are high in sugar content and stick to eating small meals during the day.
If you are having low blood sugar levels even when you havent eaten anything, you can try having a snack before hitting the bed. You can eat a snack that is rich in protein or complex carbohydrate.
In case the doctor finds out that too much if insulin is causing trouble, he/she might as well reduce the dose and observe the levels. Do follow the below mentioned routine when you have low blood sugar levels.
Test The Sugar Levels Well, this goes without saying. But, remember that the value less than 70 milligrams per deciliter means you have low blood sugar.
Try To Eat or Even Drink Some Fast Acting Carbs When you are suffering from low blood sugar, you certainly need to act quickly. You need to consume at least 15 gms of carbs. You can try taking about 4 ounces of juice or just have a tablespoon of sugar with water.
Glucose Tablets or Gel You can as well take glucose tablets or opt for the glucose gel. Medical experts say that people who take medications for diabetes need to carry glucose tablets with them for sure.
