Sugar Crash: What It Is, How It Feels, and How to Avoid It
Have you ever felt shaky, dizzy, irritable, or anxious after eating a sugary snack or a large meal? If so, you may have experienced a sugar crash. A sugar crash, also known as reactive hypoglycemia, is a condition that occurs when your blood sugar level drops too low after eating. It can make you feel tired, hungry, weak, and moody. While anyone can have a sugar crash, it is more common in people with diabetes or prediabetes.

In this article, we will explain what a sugar crash is, how it feels, and how it affects your health and mood. We will also share some tips on how to prevent and manage sugar crashes, and when to seek medical help.
What is a sugar crash?
A sugar crash is a sudden drop in blood sugar (glucose) levels that occurs within four hours of eating. Glucose is the main source of energy for your body and brain. It comes from the carbohydrates that you eat, such as fruits, vegetables, grains, and sweets.
The role of glucose and insulin in blood sugar regulation
To deliver glucose to your cells and tissues, your body needs a hormone called insulin. Insulin is produced by the pancreas in response to the amount of glucose in your bloodstream. When you eat carbohydrates, your blood sugar level rises and signals the pancreas to release insulin. Insulin then helps glucose enter the cells to be used for energy or stored for later use.
When this process works well, your blood sugar level stays within a normal range (70 to 140 mg/dL). However, sometimes this process can go wrong and cause an imbalance of glucose and insulin. This can lead to either high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia).
The causes and risk factors of sugar crash
A sugar crash is a type of hypoglycemia that occurs when your blood sugar level falls below 70 mg/dL. It usually happens when you eat too much carbohydrates or sugary foods that cause a rapid spike in your blood sugar level. This triggers the pancreas to release too much insulin, which then lowers your blood sugar level too much.

Some factors that can increase your risk of having a sugar crash include:
Prediabetes or diabetes. These conditions affect your body's ability to produce or use insulin properly.
Recent stomach surgery. This can affect how quickly food passes through your digestive system and how much insulin is released.
Certain medications. Some drugs can lower your blood sugar level or interact with insulin, such as salicylates (aspirin), sulfa drugs (antibiotics), pentamidine (an anti-parasite drug), or quinine (an anti-malaria drug).
Rare enzyme deficiencies. Some genetic disorders can affect how your body breaks down carbohydrates or produces glucose, such as hereditary fructose intolerance or glycogen storage disease.
Alcohol consumption. Alcohol can interfere with your liver's ability to release glucose into the bloodstream.
Exercise. Physical activity can increase your body's demand for glucose and lower your blood sugar level if you don't eat enough carbohydrates before or after exercising.

What are the symptoms of a sugar crash?
A sugar crash can affect your body and mind in different ways. The symptoms may vary depending on how low your blood sugar level is, how quickly it drops, and how long it lasts. Some of the common symptoms of a sugar crash include:
Physical and mental signs of low blood sugar
Shakiness or tremors
Sweating or chills
Pale or clammy skin
Rapid or irregular heartbeat
Dizziness or lightheadedness
Headache or blurred vision
Nausea or vomiting
Hunger or thirst
Fatigue or weakness
Confusion or difficulty concentrating
Memory loss or trouble speaking
Seizures or loss of consciousness (in severe cases)
How a sugar crash affects your mood and mental health
Apart from the physical and mental signs, a sugar crash can also have a negative impact on your mood and mental health. Low blood sugar can cause changes in your brain chemistry and hormones that affect your emotions and behavior. Some of the mood-related symptoms of a sugar crash include:
Irritability or anger
Anxiety or nervousness
Sadness or depression
Mood swings or emotional instability
Lack of motivation or interest
Impulsiveness or poor judgment
Aggression or violence (in rare cases)
How to recognize and treat a sugar crash
If you suspect that you are having a sugar crash, you should check your blood sugar level with a glucose meter if you have one. If your blood sugar level is below 70 mg/dL, you should treat it as soon as possible to prevent further complications. The general rule for treating a sugar crash is to follow the 15-15 rule:
Eat or drink 15 grams of fast-acting carbohydrates, such as glucose tablets, fruit juice, candy, honey, or soda.
Wait 15 minutes and check your blood sugar level again.
If your blood sugar level is still below 70 mg/dL, repeat step 1 and 2 until it is normal.
If your blood sugar level is normal, eat a snack or a meal that contains protein and complex carbohydrates, such as cheese and crackers, peanut butter and bread, or yogurt and fruit. This will help stabilize your blood sugar level and prevent another crash.
If you are unable to eat or drink anything, or if you lose consciousness, someone else should give you an injection of glucagon, a hormone that raises your blood sugar level quickly. You should also seek medical attention as soon as possible.
How to prevent and manage sugar crashes
The best way to prevent and manage sugar crashes is to keep your blood sugar level within a healthy range. This can be done by following some dietary and lifestyle tips, such as:
Dietary tips to avoid blood sugar spikes and crashes
Eat balanced meals and snacks that contain a combination of protein, complex carbohydrates, fiber, and healthy fats. These nutrients can help slow down the digestion and absorption of glucose and keep you feeling full longer.
Avoid foods and drinks that are high in simple sugars, such as candy, cookies, cakes, pastries, soda, juice, sports drinks, and energy drinks. These foods can cause rapid spikes and drops in your blood sugar level.
Limit your intake of alcohol, caffeine, and nicotine. These substances can interfere with your blood sugar regulation and increase your risk of hypoglycemia.
Eat smaller portions more frequently throughout the day. This can help prevent overeating and maintain a steady supply of glucose to your body and brain.
Monitor your blood sugar level regularly if you have diabetes or prediabetes. This can help you adjust your food intake, medication dosage, and activity level accordingly.
Lifestyle habits to support healthy blood sugar levels
Exercise regularly. Physical activity can help lower your blood sugar level by increasing your insulin sensitivity and glucose uptake by the muscles. However, be careful not to exercise too hard or too long without eating enough carbohydrates before or after exercising. This can cause hypoglycemia.
cortisol and adrenaline, which can raise your blood sugar level and make it harder for insulin to work. Try to find healthy ways to cope with stress, such as meditation, yoga, breathing exercises, or talking to a friend.
Get enough sleep. Lack of sleep can affect your hormones and metabolism, which can impair your blood sugar regulation and increase your appetite. Aim for at least seven to eight hours of quality sleep every night.
Stay hydrated. Dehydration can cause your blood sugar level to rise and make you feel thirsty, hungry, and tired. Drink plenty of water and other sugar-free fluids throughout the day.
When to see a doctor for sugar crashes
While occasional sugar crashes are usually not a cause for concern, frequent or severe episodes of hypoglycemia can indicate an underlying health problem that needs medical attention. You should see a doctor if you experience any of the following:
You have diabetes or prediabetes and your blood sugar level is often too low or too high.
You have symptoms of a sugar crash even when your blood sugar level is normal or high.
You have symptoms of a sugar crash that do not improve after eating or drinking something sweet.
You have symptoms of a sugar crash that interfere with your daily activities or quality of life.
You have symptoms of a sugar crash that are accompanied by other signs of a serious medical condition, such as chest pain, shortness of breath, vision loss, or stroke.
