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.
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.
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.

When You Have Low Blood Sugar
First, eat or drink 15 grams of a fast-acting carbohydrate, such as:
- Three to four glucose tablets
- One tube of glucose gel
- Four to six pieces of hard candy
- 1/2 cup fruit juice
- 1 cup skim milk
- 1/2 cup soft drink
- 1 tablespoon honey
Fifteen minutes after you’ve eaten a food with sugar in it, check your blood sugar again. If your blood sugar is still less than 70 mg/dL, eat another serving of one of the foods listed above. Repeat these steps until your sugar becomes normal.
Make Some Small Changes
You might try to get more exercise, or limit carbs at your next meal, but don’t go crazy. “One blood sugar that’s high doesn’t indicate a need for major changesthat should only be done on a pattern,” says Rice, such as “continuing highs despite following a doctor’s instructions.” If a pattern continues for two to three days or more, then you might want to let your health-care provider know.

How Is Hypoglycemia Diagnosed
If you suspect you have low blood sugar, its important to check your blood sugar right away. If you dont have a meter and youre on diabetes medications that increase insulin, talk with your doctor about getting a blood glucose meter.
If you experience low blood sugar often say, a few times a week see your doctor right away to determine why. Your doctor will begin your visit by requesting your medical history, asking questions about your eating habits, and learning more about the symptoms youre experiencing.
If you dont have diabetes but suspect you have hypoglycemia, talk with your doctor about your symptoms. They will perform a physical examination. They will use three criteria, sometimes referred to as Whipples triad, to diagnose low blood sugar. These include:
- Signs and symptoms of low blood sugar. Your doctor may require you to fast, or abstain from drinking and eating for an extended period of time, so they can observe your low blood sugar signs and symptoms.
- Documentation of low blood sugar when your signs and symptoms occur. Your doctor will order a blood test to analyze your blood sugar levels in a laboratory.
- Disappearance of the signs and symptoms of low blood sugar. Your doctor will want to know whether the signs and symptoms go away when your blood sugar levels are raised.
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.
What Is The Outlook For People With Hypoglycemia
Hypoglycemia can be managed when you and your healthcare provider understand what causes your blood sugar to go down. Give your healthcare provider as much information as possible about any hypoglycemic episodes. Fixing the problem may be as simple as changing the times you take medication, eat and exercise.

If any of the symptoms mentioned have begun to impact your life, such as fatigue so severe you can’t stay awake through the day, it’s a good idea to consult your physician. Dr. Fruge warns that “unstable blood sugar levels could put you at higher risk of heart disease and stroke and it is a red flag for serious health issues” — so blood sugar issues should be taken seriously.
You should also see a doctor if you’re experiencing symptoms of hypoglycemia and haven’t been diagnosed with diabetes or any other underlying condition.
If you do have diabetes and your hypoglycemia isn’t responding to the treatments described above, that’s another good cue to call your health care provider.
If testing reveals you have Type 1 diabetes, you’ll need to continue to test your blood sugar levels as often as instructed by your physician, take insulin regularly and participate in regular exercise. This may mean you will need a new glucose monitoring system, so ask your doctor what they recommend. If you’re diagnosed with Type 2 diabetes, you’ll most likely need to do the same as for Type 1, as well as working with health care professionals to make lifestyle changes such as improving nutrition and planning workouts. Medication may be necessary as well.
Healthy eating, regular exercise and other lifestyle changes can help alleviate symptoms and possibly even reverse prediabetes.

What If I Have Severe Low Blood Glucose And Cant Treat Myself
Glucagona hormone that raises blood glucose levelsis the best way to treat severely low blood glucose. Available as an injection or a nasal spray, glucagon will quickly raise your blood glucose level. Your doctor can prescribe you a glucagon kit for use in case of an emergency.
If your blood glucose level drops very low, you wont be able to treat it by yourself. Be prepared to address severely low blood glucose by
- talking with your doctor or health care team about when and how to use a glucagon emergency kit. If you have an emergency kit, regularly check the date on the package to make sure it hasnt expired.
- teaching your family, friends, and coworkers when and how to give you glucagon. Tell them to call 911 right away after giving you glucagon or if you dont have a glucagon emergency kit with you.
- wearing a medical alert identification bracelet or pendant. A medical alert ID tells other people that you have diabetes and need care right away. Getting prompt care can help prevent the serious problems that low blood glucose levels can cause.
Other Causes Of Low Blood Sugar
While low blood sugar is often associated with diabetes, it can also be affected by other factors. According to Dr. Danine Fruge, Medical Director of the Pritikin Longevity Center in Miami, Florida, the causes of blood sugar problems can include not only “diabetes, prediabetes , reactive hypoglycemia or other health issues, but also by not eating enough, taking too much insulin or even taking certain diabetes medications.”
Other medications can also cause hypoglycemia, like quinine, or Qualaquin, which is used to treat malaria, or various medications for kidney failure. Exercising more than usual can also cause it, especially while taking such medications.
Some other potential causes for low blood sugar include:
- Heavy drinking without eating
- Eating without ingesting enough carbohydrates
- Eating fewer carbs than usual without reducing insulin amounts, or improper balancing of liquid/solid carbs and timing of insulin
- Hormone deficiencies due to adrenal or pituitary tumor disorders, or in children without sufficient growth hormone
- Long-term starvation, such as that which can occur with anorexia nervosa
- Serious illness like hepatitis, kidney disorders and liver disease
- Pancreatic tumors that make the body secrete too much insulin

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.
Possible Causes With Diabetes
Diabetes affects your bodys ability to use insulin. Think of insulin as the key that unlocks your cells, letting glucose in for energy.
People with diabetes use a variety of treatments to help their bodies use the glucose in their blood. Among these are oral medications that increase insulin production and insulin injections.
If you take too much of these types of medications, your blood sugar may drop too low. People also sometimes experience low blood sugar when planning to eat a big meal, but then they do not eat enough.
Skipping meals, eating less than normal, or eating later than normal but taking your medication at your normal time can also lead to low blood sugar levels.
Unplanned excess physical activity without eating enough can also cause a drop in blood sugar levels.
Drinking alcohol when youre on these medications can also lead to low blood sugar, especially if it replaces food. When the body is trying to get rid of alcohol it becomes worse at managing blood sugar levels.
