Hypoglycemia, also known as low blood sugar, is when your blood sugar level drops below 70. Having low blood sugar is dangerous and needs to be treated right away. Left untreated, hypoglycemia can lead to unconsciousness, seizures, and though rarely, death.

What are symptoms of hypoglycemia?

Though the symptoms vary from person-to-person, most who have hypoglycemia experience the following symptoms. Some don’t feel any symptoms and symptoms don’t occur all at once.

  • Anxious feeling
  • Behavior change similar to being drunk
  • Blurred vision
  • Cold sweats
  • Confusion
  • Cool pale skin
  • Difficulty in concentrating
  • Drowsiness
  • Excessive hunger
  • Fast heartbeat
  • Headache
  • Nausea
  • Nervousness
  • Nightmares
  • Restless sleep
  • Shakiness
  • Slurred speech
  • Unusual tiredness or weakness

 

 

 

 

What Causes Hypoglycemia?

Hypoglycemia can occur a number of ways, but the chances of hypoglycemia in people with Type 2 diabetes are increased with the use of insulin and other diabetes medications. Hypoglycemia may occur when the amount of insulin or other medication taken isn’t aren’t matched with intake of carbohydrates. It may also be caused by activities such as exercise, the timing of meals, consumption of alcohol, or being sick.

If you’re experiencing lows frequently, you may not need as much insulin or another form of diabetes medication. Talk to your doctor or healthcare provider about adjusting dosages. Patients taking the oral medications sulfonylureas and meglitinides should be aware that they can cause hypoglycemic side effects.

You’re at risk for hypoglycemia, including severe hypoglycemia if you:

The American Diabetes Association divides hypoglycemia by levels:

  • Level 1: Blood glucose value of 70 mg/dL or less
  • Level 2: Blood glucose value of 54 mg/dl or lower which is considered low enough to indicate clinically relevant hypoglycemia
  • Level 3: Severe hypoglycemia, refers to hypoglycemia where there is cognitive disability that requires help from a third person for recovery, treatment suggested is glucagon.

How Do You Treat Hypoglycemia?

It’s important to know that treatment of hypoglycemia depends on the severity of the low blood sugar reading. It also depends on if person having hypoglycemia is alert. If you can, seek help from a family member, friend, or a doctor for treating hypoglycemia.

If your meter shows that your blood sugar is low, it’s recommended that you eat or drink about 15g of fast acting sugars. Each of the following are recommended ways to treat a low blood sugar (pick one):

  • Chew 4 glucose tablets
  • Drink 4 ounces of fruit juice
  • Drink 4 ounces of regular soda, not diet soda or
  • Chew 4 pieces of hard candy

After taking one of these treatments, wait for 15 minutes, then check your blood sugar again. Repeat these steps until your blood sugar is 70 or above. After your blood sugar gets back up to 70 or more, eat a snack if your next meal is 1 hour or more away.

If you experience low blood sugars often, it’s a good idea to always,check your blood sugar before driving. Treat and make sure it is in a safe range before getting behind the wheel.

Treating Severe Hypoglycemia  

If someone with diabetes has a low blood sugar and is not responsive, convulsing, or not able to orally ingest sugar for any reason, emergency glucagon must be administered.

If you are conscious but cannot consume sugar orally, you can self-administer glucagon. If you are unconscious, someone else will need to inject the glucagon into muscle. If hospitalized, the injection may be given intravenously. Always contact emergency services if glucagon is administered in an emergency situation.

Read all about glucagon, including a step-by-step treatment to administer.

Blood Sugar Spikes After a Low

In about 20% of cases, rebound hyperglycemia (high blood sugar) occurs after a low. Over-correction with carbohydrates is the main cause of rebound hyperglycemia. It is recommended to give no more than 20 grams of carbohydrate for correction of blood glucose between 50-70 mg/dl (3-4 mmol/L) and as noted previously, to check BG levels as needed in 15 minute increments, giving 15 grams more of carbs until levels rise.

Consult with Your Endo

It’s imperative to monitor and treat low blood sugars immediately in order to prevent severe hypoglycemia and unconsciousness. If you routinely experience hypoglycemia, talk to your endocrinologist about how you should make adjustments to your medication.
