The concept of a “sugar crash” is nothing new-- the sense of exhaustion, irritability, and potential headaches that come after eating too many sweets is a universal experience. But why do blood sugar crashes happen, and are they avoidable? To learn how to curb your blood sugar crashes, read on:

What is a Sugar Crash?

A blood sugar crash (scientifically known as hypoglycemia) occurs when the body is low on blood sugar, or glucose. Our bodies respond to sugars by releasing insulin into the bloodstream. The insulin then processes excess sugar and stores it for use later, when we need energy. If the blood has more insulin than glucose, blood sugar levels can drop below average and trigger hypoglycemia. People without diabetes can experience blood sugar crashes in the form of non-diabetic hypoglycemia.

Blood Sugar and Diabetes

People with diabetes have difficulty producing insulin to regulate and process glucose. Because of this, blood sugar crashes can be pretty common. High blood sugar can occur and must be treated with insulin supplements to avoid health complications associated with high blood sugar. To monitor blood sugar levels, people with diabetes use blood sugar monitors.

Hypoglycemia Symptoms

Symptoms of a sugar crash tend to vary from person to person, but the most common symptoms of a sugar crash include:

  • Dizziness or lightheadedness
  • Exhaustion and lethargy
  • Hunger
  • Shakiness
  • Headaches


Other symptoms of hypoglycemia include:

  • Irritability
  • Anxiety
  • Sweating, chills, and clamminess
  • Confusion or difficulty concentrating
  • Blurred vision
  • Numbness around the mouth and at arms and legs
  • Nightmares
  • Seizures


Since each person has a different set of symptoms when they’re low on blood sugar, most people tend to learn loved ones’ signs of hunger or low blood sugar over time.

Recovering from a Sugar Crash

People without diabetes will find plenty of home remedies for their low blood sugar, especially in the pantry. Eating is the best way to recover your blood sugar, and while some may immediately reach for a candy bar, a balanced diet of proteins and carbohydrates will help reduce symptoms faster. In addition, avoiding alcohol and caffeine during and after a sugar crash may help lessen symptoms.

Avoiding a Blood Sugar Crash

To avoid hypoglycemia entirely, there are several dietary recommendations to follow:

  • Eating less food more often can help space out the body’s blood sugar intake, allowing for even glucose levels throughout the day.
  • Eating a wide variety of foods can introduce other sugars, fats, and proteins into the body-- all of which are vital for creating and storing energy.
  • Planning meals can help you get a variety of foods in your diet, especially if you’re on a budget.
  • Eating simple sugars with other foods will allow these sugars to enter the body and not just pass right through you. Simple sugars include fruit juices, sweets or candy, milk, and other foods containing processed sugars.
  • Avoiding dietary restrictions is by far one of the best ways to prevent blood sugar crashes. The wider the variety of foods you eat, the less likely you are to experience a sugar crash. For people struggling with eating disorders, this goes doubly so-- any food is good food if you’re hungry.
