Teens who do have hypoglycemia usually have it as part of another health condition, such as <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/center/diabetes-center.html/">diabetes</a>.</span></p> <h3>What Is Hypoglycemia?</h3> <p><strong>Hypoglycemia</strong> happens when a person's blood sugar levels are abnormally low, and it's a potentially serious condition. If you know someone who has diabetes, you may have heard them talk about "insulin shock," which is the common name for a severe hypoglycemic reaction.</p> <p>The body's most important fuel is glucose, a type of sugar. When you digest most foods, sugar is released, and that sugar ends up in your bloodstream as glucose. Your body, particularly your brain and nervous system, needs a certain level of glucose to function &mdash; not too much, and not too little. If your blood glucose level isn't right, your body will react by showing certain symptoms.</p> <p>People with diabetes may experience hypoglycemia if they don't eat enough or if they take too much insulin &mdash; the medicine most commonly used to treat diabetes.</p> <h3>What Are the Symptoms?</h3> <p>Some symptoms of hypoglycemia are caused when the body releases extra adrenaline (epinephrine), a hormone that raises blood sugar levels, into the bloodstream to protect against hypoglycemia. High blood levels of adrenaline can make the skin become pale and sweaty, and a person can also have symptoms such as shakiness, anxiety, and heart palpitations (a fast, pounding heartbeat).</p> <p>Other symptoms of hypoglycemia are caused when not enough glucose gets to the brain; in fact, the brain is the organ that suffers most significantly and most rapidly when there's a drop in blood sugar. These symptoms include headache, extreme hunger, blurry or double vision, fatigue, and weakness. At its most severe, insufficient glucose flow to the brain can cause confusion, seizures, and loss of consciousness (coma).</p> <h3>Who Gets Hypoglycemia?</h3> <p>Almost all teens who take blood sugar-lowering medicine for diabetes get hypoglycemia from time to time. Insulin moves sugar out of the blood and into the body's cells, where it's used as a fuel. Someone with diabetes who takes too much insulin or doesn't eat enough food to balance the effects of insulin may have a drop in&nbsp;blood sugar.</p> <p>Hypoglycemia related to not eating rarely happens in teens and adults unless the starvation is severe, as in <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/eat-disorder.html/">anorexia</a>.</p> <p>Poisoning or overdoses of some substances, such as <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/alcohol.html/">alcohol</a>, or certain drugs, like insulin or other diabetes medicines, can cause some otherwise healthy people to develop hypoglycemia. People with certain types of <a class="kh_anchor">cancer</a> or severe chronic illness also can get hypoglycemia. There are also rare genetic forms of hypoglycemia, but the symptoms are severe and almost always begin in infancy.</p> <p>If hypoglycemia is so rare among people in their teen and adult years, why do a lot of people think they have it?</p> <p>There are a couple of reasons. For one thing, the symptoms that happen with hypoglycemia overlap with those that people can have for many other reasons &mdash; or no reason at all. It's normal to feel very tired or weak, or have a headache periodically, especially if someone has had a <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/stress.html/">stressful</a> day or too little <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/sleep.html/">sleep</a>. And drinking a lot of coffee, cola, or other <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/caffeine.html/">caffeine</a>-containing beverages can certainly make a person feel a bit shaky or jittery.</p> <p>Also, it seems that some people's bodies react differently to eating high amounts of sugar than others. When these people eat meals that contain lots of sugar and starch, the rise and fall of blood sugar that results can trigger hypoglycemia-like symptoms. This can happen even though the blood sugar doesn't actually drop to below-normal levels.</p> <h3>How Is Hypoglycemia Diagnosed?</h3> <p>A doctor who thinks a person might have hypoglycemia will ask about the patient's medical history and diet, in particular about the timing of the symptoms, whether they tend to happen after eating high-sugar meals, and if the symptoms go away quickly with eating sugar.</p> <p>The only way to tell for sure whether someone's symptoms are related to hypoglycemia is to test the blood sugar while the person&nbsp;is having the symptoms. If the test shows that the blood sugar is truly low, the doctor may do other tests to diagnose specific diseases that can cause hypoglycemia.</p> <h3>How Is Hypoglycemia Treated?</h3> <p>The treatment of hypoglycemia depends upon its cause. If you're otherwise healthy and you notice occasional hypoglycemia-like symptoms, try eating a diet that's lower in simple sugars and/or try cutting down on your caffeine intake. If this doesn't make the symptoms go away, be sure to talk with your doctor.</p>
Carbohydrates and DiabetesIf you have diabetes, your doctor may have recommended keeping track of how many carbohydrates (carbs) you eat. But what exactly are carbs and how do they affect your blood sugar?https://kidshealth.org/ws/RadyChildrens/en/teens/carbs-diabetes.html/bc86697f-835a-4745-99eb-cd7f807b9b7b
DehydrationDehydration is when the amount of water in the body has dropped too low. Read about what causes dehydration, what it does to your body, and how to prevent it.https://kidshealth.org/ws/RadyChildrens/en/teens/dehydration.html/4dbb09f6-59a5-4398-a00e-944efd28f3d3

Diabetes Control: Why It's ImportantPeople who have diabetes may hear or read a lot about controlling, or managing, the condition. But what is diabetes control and why is it so important?https://kidshealth.org/ws/RadyChildrens/en/teens/diabetes-control.html/f02a787a-3326-4ffb-bee2-d2c965896f13
Keeping Track of Your Blood SugarTo keep your diabetes under control, stay healthy, and prevent future problems, you need to keep blood sugar levels in a healthy range. To do that, check and track those levels regularly.https://kidshealth.org/ws/RadyChildrens/en/teens/track-blood-sugar.html/723dff80-03a4-4bdf-a5e9-d21412553ea8
When Blood Sugar Is Too HighFor people with diabetes, controlling blood sugar levels is important. Having a blood sugar level that's too high can make you feel lousy, and having high blood sugar levels a lot can be unhealthy.https://kidshealth.org/ws/RadyChildrens/en/teens/high-blood-sugar.html/76e71f3a-c621-4474-8266-4cde74bfc4f3
When Blood Sugar Is Too LowWhen blood glucose levels drop too low, it's called hypoglycemia. Very low blood sugar levels can cause severe symptoms that need to be treated right away.https://kidshealth.org/ws/RadyChildrens/en/teens/blood-sugar-low.html/c07944f1-52e3-4d8f-8145-1cd35c261cd3
