Hypoglycemia: Causes, Symptoms, and Treatment

For people with diabetes, there can be a number of other health complications they experience, such as Hypoglycemia. When our blood sugar drops to abnormally low levels, our body’s function is impaired. Hypoglycemia occurs when a person’s blood glucose level drops below 70 milligrams per deciliter (mg/dL).

Before we jump in to what low blood sugar symptoms are, we’ll discuss what causes blood sugar to drop.

What Causes Blood Sugar to Drop?

For people with diabetes, their body’s ability to use insulin is affected. Because of this, glucose might build up in the bloodstream to dangerously high levels. Usually, insulin or other medications are used to help regulate blood sugar levels.

However, blood sugar may drop if a person with diabetes takes too much insulin. Hypoglycemia may also occur if a person has not eaten a meal recently. Or, they may be exercising more than normal.

Excessive alcohol drinking and a few critical illnesses may cause hypoglycemia as well. Be sure to monitor your diet, activity and medication intake.

There is no one best low blood sugar treatment. Yet, there are plenty of options for people manage blood sugar. Eat or drink something that’s mostly sugar or carbohydrates.

However, foods with more fat do not raise your low blood sugar levels as quickly. Here are some low blood sugar treatment options:
