After You Have Low Blood Sugar
If your low blood sugar was mild , you can return to your normal activities once your blood sugar is back in its target range.
After you have low blood sugar, your early symptoms for low blood sugar are less noticeable for 48 to 72 hours. Be sure to check your blood sugar more often to keep it from getting too low again, especially before eating, physical activity, or driving a car.
If you used glucagon because of a severe low , immediately call your doctor for emergency medical treatment. If you have had lows several times close together , you should also tell you doctor. They may want to change your diabetes plan.
Why Is Insulin A Factor In Low Blood Sugar
Insulin is a hormone that allows glucose to enter the cells from the blood which lowers blood glucose/sugar levels. In people without diabetes, the pancreas knows how much insulin it needs to release in order to lower blood sugar.
But for people with diabetes when deciding themselves how much insulin is needed this is less straightforward. A person can have a good understanding of what the body might need, through calculations.
But there is a great deal to consider, which can be overwhelming sometimes. As a result, errors in calculating insulin can and do occur. Thats why diabetes applications like Hedia, wink, wink exist.
Hedias insulin calculator will take away the worries of figuring it out for yourself. You dont even need to enter your blood sugar readings yourself: they can be added wirelessly with certain NFC or Bluetooth glucose meters to Hedia!
Start to take those worries away by downloading Hedia from the App Store or !
This should all lead to more accurate results. In turn, this means that a rapid drop in blood sugar should be less likely.
But its not only about human errors or miscalculations. Its also about the nature of insulin medication.
Specifically, many people with diabetes nowadays use rapid-acting insulin at mealtimes in order to counteract the rapid rise in blood sugar after eating.
Its All About Balance Moderation And Consistency
The sugar high is all fun and games until the resulting sugar crash affects the quality of your day.
The term refers to the sudden drop in energy levels after consuming a large amount of carbohydrates. This can include pastas and pizza but is usually more common after eating simple carbohydrates, also known as simple sugars, such as desserts.
A sugar crash often causes undesired symptoms that can disrupt productivity and energy levels throughout the day.
Kelsey Herrick, senior dietitian at Sanford Health, suggests balance, moderation and consistency are the most effective ways to avoid these crashes. Herrick shares her knowledge on sugar crashes, how to avoid them and what to do if you get one.

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.
How To Treat Someone Who’s Having A Seizure Or Fit

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.

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
Things To Know About Hypoglycemia Unawareness
Sometimes hypoglycemia may even occur in your sleep, causing nightmares and sweating. Previous research published in Diabetes Care has also indicated that people with type 1 diabetes may have an increased risk of hypoglycemic-related cardiac arrest during sleep.
For people with type 2 diabetes, its possible to experience hypoglycemia after eating a large, carbohydrate-heavy meal due to higher levels of insulin circulating in the body, Dodell adds.
Your risk for hypoglycemia depends on your health and how well youre managing your blood sugar.
Aside from any possible diabetes medication side effects, the Mayo Clinic notes that your blood sugar levels may decrease as a result of:
- Skipping regular meals

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.
What Causes Blood Sugar To Drop Rapidly Apart From Too Much Insulin
Clearly, then, too much insulin is what causes blood sugar to drop rapidly. But theres more to it than simply taking too much insulin.
Skipping meals or eating less than what youre used to will also mean having too much insulin in the body.
In addition, the bodys sensitivity to insulin can change throughout the day. The greater the insulin sensitivity, the less insulin the body will need. If insulin sensitivity has increased, this will often be due to the combination of exercise and diabetes.
These are probably the most common reasons for low blood sugar, as the blog post What Happens when Blood Sugar is low? points out. NHS inform gives some other reasons, such as:
Fasting. Aside from not taking in any carbs for the insulin to displace, fasting can also lead to not having enough nutrients, which can hinder the bodys digestive abilities.
Similarly, illness can impact the bodys response to glucose. Illness will usually increase blood sugar but it depends on what kind of illness and how your body responds to it which can give low blood sugar. Read more on this topic with Diabetes and the Flu.
Meanwhile, sleep itself may not lower blood sugar, but you can still get low blood sugar in the night for the same reasons you would in in the day.
The only difference is that you cant treat it as effectively because youre well asleep. So, do have carbs ready by your bed, just in case. Read more on Diabetes and Sleep.
