What Are The Signs And Symptoms Of Hypoglycemia
Hypoglycemia tends to present as a cluster of symptoms, and they often occur together. The most common signs of dangerously low blood sugar include:
Dizziness, disorientation, light-headedness, and an inability to think clearly
Hunger, especially if youve just eaten
Heightened irritability, confusion, and anxiety
Clamminess and sweating, with cold hands and feet
Drastic mood swings
If you have one or more of these symptoms contact your doctor.
A Low Blood Sugar Level Without Diabetes
A low blood sugar level is uncommon in people who do not have diabetes.
Possible causes include:
- a gastric bypass
- other medical conditions, such as problems with your hormone levels, pancreas, liver, kidneys, adrenal glands or heart
- some medicines, including quinine
See a GP if you think you keep getting symptoms of a low blood sugar level. They can arrange some simple tests to check if your blood sugar level is low and try to find out what’s causing it.
Possible Causes Without Diabetes
Hypoglycemia in people without diabetes is much less common. But it can occur and some if the causes can include:
Medication: Taking someone elses oral diabetes medication accidentally is a possible cause of hypoglycemia.
Excessive alcohol drinking: Drinking heavily without having eating can block your liver from releasing glucose into your bloodstream, causing hypoglycemia.
Some critical illnesses: Severe liver illnesses such as severe hepatitis or cirrhosis can cause hypoglycemia.
Long-term starvation, as can occur in the eating disorder anorexia nervosa, can result in too little of substances your body needs to create glucose.
Insulin overproduction: A rare tumor of the pancreas, known as insulinoma, can cause you to produce too much insulin, resulting in hypoglycemia.
Hormone deficiencies: Certain adrenal gland and pituitary tumor disorders can result in a deficiency of key hormones that regulate glucose production.
What Is Low Blood Sugar
Low blood sugar is a level of sugar, or glucose, in the blood that is lower than normal. According to the American Diabetes Association, the cut-off value for Level 1 hypoglycemia, or moderately low blood sugar, is 70 mg/dl. However, you may not be regularly measuring your blood sugar if you have not been diagnosed with diabetes. Instead, you might suspect that you have hypoglycemia because of its symptoms. The fatigue, fuzzy thinking, and need to sit down are the result of your body being deprived of its main fuel source: glucose.

Where Can I Find Support For My Hypoglycemia
The Hypoglycemia Support Foundation, established nearly 40 years ago, is a national group that offers many resources, including advocacy. They offer salons so that you can personally connect with people like you who are also dealing with bouts of low blood sugar.
Occasionally blood sugar crashes are so extreme they require emergency room care for an immediate dextrose IV treatment. If you have diabetes, wear a medical bracelet so that emergency personnel or bystanders who call for help are aware of this information. Its also a good idea to have a circle of people who serve as close contacts and are aware of your condition and how to help.

How Can I Prevent Hypoglycemic Episodes
The key to preventing hypoglycemic events is managing diabetes:
- Follow your healthcare providers instructions about food and exercise.
- Track your blood sugar regularly, including before and after meals, before and after exercise and before bed.
- Take all your medications exactly as prescribed.
- When you do have a hypoglycemic event, write it down. Include details such as the time, what you ate recently, whether you exercised, the symptoms and your glucose level.
When Your Blood Sugar Gets Low
Check your blood sugar whenever you have symptoms of low blood sugar. If your blood sugar is below 70 mg/dL, treat yourself right away.
1. Eat something that has about 15 grams of carbohydrates. Examples are:
- 3 glucose tablets
- One half cup of fruit juice or regular, non-diet soda
- 5 or 6 hard candies
- 1 tablespoon or 15 mL of sugar, plain or dissolved in water
- 1 tbsp of honey or syrup
2. Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain.
3. Check your blood sugar again.
4. If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL , eat another snack with 15 g of carbohydrates.
You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range — over 70 mg/dL — and your next meal is more than an hour away.
Ask your provider how to manage this situation. If these steps for raising your blood sugar do not work, call your doctor right away.

What Should I Do If This Happens
People and their partners or roommates should learn to recognize the signs of nighttime hypoglycemia. Be prepared! Ask your doctor for an emergency glucagon kit. This kit contains a fast-acting medication that can be injected if the person cant be woken up. Store the kit in a bedside drawer for easy access.
DO NOT PUT ANYTHING INTO A PERSON’S MOUTH IF THEY ARE ASLEEP OR CANNOT SIT UP.
If the person cannot be woken: If there is no emergency glucagon kit, call 911. If the person has a glucagon kit, the partner or roommate should follow the instructions to fill the syringe and inject the medicine. Once fully awake, he/she should eat a meal and check their blood glucose every few hours using a home test kit. After giving the injection, the persons doctor should be notified.
If the person can be woken up and sit without support: They should be given a fast-acting glucose source. Good options include hard candy, fruit juice or glucose paste or tablets, which can be purchased at most pharmacies. Once the person is fully awake, they should eat a meal and check their blood glucose every few hours using a home test kit.
How To Test Your Blood Sugar At Home
To perform a blood sugar test, you will need to prick your finger with a lancet . Youll put a small sample of blood from this onto a strip inserted into the blood glucose meter.
Before you test your blood sugar at home, its important to find out from your doctor what a healthy blood sugar range is for you. Your doctor will determine this range based on factors such as:
- the type of diabetes you have
- how long youve had diabetes
- whether you have any other chronic health conditions
If you dont have a blood sugar testing machine on hand and are experiencing signs or symptoms of low blood sugar with diabetes, your symptoms may be enough to diagnose low blood sugar.

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.
Don’t Miss: What Is High Glucose Levels
Rebound Hypoglycemia After Eating
If sugar comes from the food you eat, why would blood sugar be low after eating? It may be due to a phenomenon called reactive hypoglycemia. This refers to low levels of blood glucose that react to high levels. According to Mayo Clinic, it can occur within 4 hours of eating a meal.
Say breakfast includes pancakes, syrup, and fruit juice. The meal is full of carbs: starch in the pancakes, added sugar in the syrup, and natural sugar in the fruit juice. Those carbohydrates get absorbed fast.
Blood sugar can skyrocket, especially in people who have prediabetes or diabetes. You may feel a sugar high, or burst of energy, within minutes to an hour of eating. Thenthe crash. The higher they fly, the harder they fall, is spot-on for blood sugar. If it went up, up, up, it will go down, down down, possibly below normal levels and into the range of hypoglycemia.

Traveling Can Disrupt Routines And Thus Sugars
Skipping a few time zones during a long flight throws almost everyone off, but it’s an even bigger concern for people with diabetes. The time change can disrupt your medication schedule and cause unusual eating and sleeping habits, which interfere with blood sugar control, McDermott says.
Plus, when youre on vacation or traveling, you may eat more, drink more alcohol, or be more active all of which can cause blood sugar swings. She advises checking your blood sugar more frequently while traveling to catch any concerning trends before they become serious problems.
McDermott also recommends packing healthy carb-balanced snacks as well as a refillable water bottle to help you stay hydrated. Try to eat something every four hours throughout the day, even if it cant be at the exact same times you usually eat. If you take insulin and you’re shifting time zones, be sure to work out a medication schedule with your diabetes care team before your trip so you don’t mistime any doses, she says.

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

The Effects Of Low Blood Sugar On Your Body
Every cell in your body needs energy to function. The main source of energy might come as a surprise: Its sugar, also known as glucose. Blood sugar is essential to proper brain, heart, and digestive function. It even helps keep your skin and vision healthy.
When your blood sugar levels fall below the normal range, its called hypoglycemia. There are many identifiable symptoms of low blood sugar, but the only way to know if you have low blood sugar is by taking a blood glucose test.
Learn more about the symptoms of low blood sugar, as well as the long-term effects on the body.
most common reasons for low blood sugar are some medications used to treat diabetes, such as insulin.
In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesnt make enough insulin, or your body cant use it properly. Too much insulin or oral diabetic medication can lower the blood sugar level, leading to hypoglycemia.
However, contrary to popular belief, low blood sugar isnt exclusive to diabetes, though it is rare. It can also happen if your body makes more insulin than it should.
Another possible cause of low blood sugar is drinking too much alcohol, especially over long periods of time. This can interfere with the livers ability to create a buildup of glucose and then release it into your bloodstream when you need it.
