What happens when blood sugar drops during exercise?
Exercise-induced hypoglycemia (EIH) is the medical term for low blood sugar during or after exercise. The condition can cause a range of symptoms, including weakness, shakiness, and intense fatigue. Glucose is the body’s primary source of energy.
Can you run with low blood sugar?
If you want to continue your workout, you will usually need to take a break to treat your low blood sugar. Check to make sure your blood sugar has come back up above 100 mg/dl before starting to exercise again. Keep in mind that low blood sugar can occur during or long after physical activity.
Does blood sugar affect running?
New research in the journal Nature Metabolism suggests having consistently high blood sugar could affect your running performance by preventing muscle growth in response to your training. A diet high in processed sugars and saturated fat is often the biggest culprit to high blood sugar.
Can intense exercise cause low blood sugar?
Exercise also affects various hormones which have a direct impact on blood sugar levels. It’s not surprising then, that non-diabetic hypoglycemia (or low blood sugar) is common in frequent exercisers and athletes.
How can exercise induced hypoglycemia be prevented?
Exercise Timing
Since exercise-induced hypoglycemia can occur during, immediately, or even 48 hours after exercise [18], exercising in the evening may cause hypoglycemia while sleeping. Therefore, exercising too late in the evening should be prevented.
How long after exercise will blood sugar drop?
In most folks, 30-60 minutes after exercise, levels will lower. Often in type 1 diabetes, however, it takes longer for levels to come down post exercise.
What causes you to pass out after exercise?
While fainting after exercise, a condition called syncope, can indicate a serious heart disorder, most cases are linked to low blood pressure and low blood flow to the brain.
Can you have low blood sugar and not be diabetic?
A low blood sugar level without diabetes
A low blood sugar level is uncommon in people who do not have diabetes. Possible causes include: your body releasing too much insulin after eating (called reactive hypoglycaemia or postprandial hypoglycaemia) not eating (fasting) or malnutrition.
Why do I feel shaky and nauseous after working out?
Your muscles use glucose for fuel. When you work out, your glucose levels can become depleted, especially if you exercise at a vigorous pace or for a long period of time. This can lead to low blood sugar, also known as hypoglycemia. Without enough fuel, your muscles may begin to shake.
Is hypoglycemia a diabetes?
Hypoglycemia is a condition in which your blood sugar (glucose) level is lower than the standard range. Glucose is your body’s main energy source. Hypoglycemia is often related to diabetes treatment. But other drugs and a variety of conditions — many rare — can cause low blood sugar in people who don’t have diabetes.
How much does exercise lower blood sugar?
Good news: Two new studies found that exercising 30 minutes a day reduces your risk of diabetes by 25 percent, and walking for 10 minutes after meals lowers your blood sugar by 22 percent.
Why do I get shaky after physical activity?
Your muscles use glucose for fuel. When you work out, your glucose levels can become depleted, especially if you exercise at a vigorous pace or for a long period of time. This can lead to low blood sugar, also known as hypoglycemia. Without enough fuel, your muscles may begin to shake.
Can exercise cause hypoglycemia in diabetics?
In people with well-controlled diabetes treated with insulin or insulin secretagogues, moderately intense exercise can induce hypoglycemia, and the ADA advises that supplemental carbohydrate should be consumed if blood glucose levels are less than 100 mg/dl (5.6 mmol/l) prior to the start of exercise [121].
How does hypoglycemia affect sports performance?
Nocturnal hypoglycemia was present in 66% of subjects, lasting an average of 84 minutes, but this did not affect sports skill performance the following day. Conclusions. Mild hypoglycemia markedly reduces sports skill performance and cognition in young athletes with T1DM.

What are the warning signs of hypoglycemia?
Initial signs and symptoms of diabetic hypoglycemia include:
- Looking pale (pallor)
- Shakiness.
- Dizziness or lightheadedness.
- Sweating.
- Hunger or nausea.
- An irregular or fast heartbeat.
- Difficulty concentrating.
- Feeling weak and having no energy (fatigue)
How do I know if I have reactive hypoglycemia?
Symptoms of reactive hypoglycemia
- Shaking or trembling.
- Sweating and chills.
- Dizziness or lightheadedness.
- Faster heart rate.
- Headaches.
- Hunger.
- Nausea.
- Nervousness or irritability.
How long can hypoglycemia last?
Hypoglycemia caused by sulfonylurea or long-acting insulin may take longer to resolve, but usually goes away in one to two days.
How long does it take for hypoglycemia to damage the brain?
Profound, prolonged hypoglycemia can cause brain death. In studies of insulin-induced hypoglycemia in monkeys, 5–6 hours of blood glucose concentrations of less than 1.1 mmol/l (20 mg/dl) were required for the regular production of neurological damage (12); the average blood glucose level was 0.7 mmol/l (13 mg/dl).
What happens to the brain during hypoglycemia?
Hypoglycemia impairs simple brain functions and is associated with task-specific localized reductions in brain activation. For a task with greater cognitive load, the increased BOLD signal in planning areas is compatible with recruitment of brain regions in an attempt to limit dysfunction.
What does a sugar crash feel like?
Sugar crashes generally cause us to be incredibly distracted throughout the day, which leads to a lack of productivity and concentration. Confusion, abnormal behavior, the inability to complete routine tasks and blurred vision are also common symptoms, especially for those who have diabetes.
Why would blood sugar drop suddenly?
Your blood sugar can drop quickly if you don’t eat enough food or you skip meals. It can also happen if you take too much medicine (insulin or pills), exercise more than usual, or take certain medicines that lower blood sugar. Do not drink alcohol if you have problems noticing the early signs of low blood sugar.
How do you wake up from a sugar crash?
If you start experiencing symptoms of a sugar crash, the short-term solution is to eat 15 grams of a carbohydrate. If your symptoms don’t improve after 15 minutes, eat another 15 grams of a carbohydrate.
What is a sugar coma?
A diabetic coma is a life-threatening diabetes complication that causes unconsciousness. If you have diabetes, dangerously high blood sugar (hyperglycemia) or dangerously low blood sugar (hypoglycemia) can lead to a diabetic coma.
At what blood sugar level does damage occur?
First, the numbers. “Post-meal blood sugars of 140 mg/dl [milligrams per deciliter] and higher, and fasting blood sugars over 100 mg/dl [can] cause permanent organ damage and cause diabetes to progress,” Ruhl writes.
