Rebound Hypoglycemia After Eating

Why Do Your Blood Sugar Levels Change?

If sugar comes from the food you eat, why would blood sugar be low after eating? It may be due to a phenomenon called reactive hypoglycemia. This refers to low levels of blood glucose that react to high levels. According to Mayo Clinic, it can occur within 4 hours of eating a meal.

Say breakfast includes pancakes, syrup, and fruit juice. The meal is full of carbs: starch in the pancakes, added sugar in the syrup, and natural sugar in the fruit juice. Those carbohydrates get absorbed fast.

Blood sugar can skyrocket, especially in people who have prediabetes or diabetes. You may feel a sugar high, or burst of energy, within minutes to an hour of eating. Thenthe crash. The higher they fly, the harder they fall, is spot-on for blood sugar. If it went up, up, up, it will go down, down down, possibly below normal levels and into the range of hypoglycemia.

What Are The Treatments For Hypoglycemia

Make an appointment with an endocrinologist if you feel like youre having episodes of hypoglycemia, even if youre not diabetic. Theyll talk you through treatment strategies, including:

  • Adjusting your medications. You may need to change how often you take insulin or other medications, which medications youre on, how much you take, and when you take them.
  • Working with a registered dietitian on a personalized meal plan that stabilizes blood sugar levels. Theres no one-size-fits-all hypoglycemia diet, but a nutritionist can help you figure out a consistent meal plan tailored to you, and teach you how to count carbohydrate grams to go along with your health and routine.
  • Increasing and improving self-monitoring of your blood glucose levels. Knowing your blood glucose level throughout the daywhen you get up, before meals, and after meals etc.can help you keep it from getting too low.
  • Limiting consumption of alcoholic beverages. Alcohol interferes with the way your body metabolizes glucose. If you’re prone to hypoglycemia, consider decreasing how much alcohol you consume.
  • Glucose tablets . Make sure you always have glucose tablets on hand, whether at home, school, the office, or the gym. After taking the tablet, check your blood sugar. If its still low, take another tablet. If that doesnt help, check with your doctor.

If A Person Is Unconscious

If a person loses consciousness because of severe hypoglycaemia, they need to be put into the recovery position and given an injection of the hormone glucagon . The injection will raise their blood glucose level.

The injection should be carried out by a friend or family member who knows what theyre doing, or by a trained healthcare professional.

You should dial 999 to request an ambulance if:

  • a glucagon injection kit isnt available
  • theres nobody available whos trained to give the injection
  • the injection is ineffective after 10 minutes

Never try to put food or drink into the mouth of someone whos unconscious as they could choke.

If youre able to give a glucagon injection and the person regains consciousness, they should eat some longer-acting carbohydrate food, such as a few biscuits, a cereal bar or a sandwich.

You should continue to monitor the person for signs of recurring symptoms in case they need to be treated again.

    How Is Hypoglycemia Treated

    When your blood sugar levels are too low, eating carbohydrates is key. If you have diabetes, try to keep high carbohydrate snacks on hand.

    The American Diabetes Association recommends that your snack have at least 15 grams of carbohydrates. Some good snacks to keep on hand are:

    • hard candies
    • jelly beans or gumdrops
    • fresh or dried fruit

    You also can take glucose tablets to rapidly raise your blood sugar if its low. These are available without a prescription. Its important to check how many grams are in each tablet before taking them. Aim to get 15 to 20 grams of carbohydrates.

    Wait 15 minutes after eating or taking a glucose tablet and test your blood sugar again. If your blood sugar is not going up, eat another 15 grams of carbohydrates or take another dose of glucose tablets. Repeat this until your blood sugar level starts to rise.

    Be sure not to overeat. This could lead to blood sugar levels that are too high.

    If your blood sugar remains unresponsive, contact your doctor or emergency services right away. When in doubt, treat.

    Symptoms of low blood sugar usually get worse if theyre left untreated. Make an appointment to see your doctor if you have diabetes and experience low blood sugar levels often, or if you have symptoms, even if you dont have diabetes.

    Why Do Chores Drop Blood Sugars?

    If you have diabetes and are experiencing mild to moderate hypoglycemia symptoms, you need to immediately eat or drink 15 grams of easily digestible carbohydrates.

    Very low blood sugar is a medical emergency. If you or someone else with diabetes is experiencing severe symptoms, such as unconsciousness, its important to administer a medication called glucagon and contact emergency services immediately.

    If youre at risk for low blood sugar, its important to talk with your doctor about getting a prescription for glucagon.

    You should never give an unconscious person anything by mouth, as it could cause them to choke. If you have diabetes, make sure your family and friends know not to do this if you lose consciousness.

    Low blood sugar can occur for a number of reasons. Its usually a side effect of diabetes treatment.

    The Importance Of Treating Low Blood Sugar Immediately

    Always treat hypoglycemia right away. Even if an emergency doesn’t occur, a continued drop in blood sugar levels can affect your thinking – for example, you might not even realize you have to eat or drink something to bring up your blood sugar. That means you’ll have to rely on someone else tohelp you. If no one’s around, things can get much more serious. For instance, you might decide to drive, but because your muscles are affected by low blood sugar, you could be at higher risk to get into an accident.

    If your blood sugar drops below 20 mg/dl you may lose consciousnses.This is an emergency situation and requires prompt care as it can leadto serious consequences such as heart attack or a seizure.

    Teach people close to you what to be aware of and what to do in case you can’t treat yourself. You might also want to teach them how to test yourblood sugar.

    Although it’s useful to know what to do when your blood sugar drops, it’s easier to prevent low blood sugar levels rather than treat it after it’s happened. Monitor your blood sugar levelsregularly with a glucometeror home testing kit. If you continue to have repeated episodes of hypoglycemia, talk to your healthcare professionals to discuss changes to your diabetes treatmentplan.

    Nighttime Low Blood Sugar

    While low blood sugar can happen at any time during the day, some people may experience low blood sugar while they sleep. Reasons this may happen include:

    • Having an active day.
    • Being physically active close to bedtime.
    • Taking too much insulin.
    • Drinking alcohol at night.

    Eating regular meals and not skipping them can help you avoid nighttime low blood sugar. Eating when you drink alcohol can also help. If you think youre at risk for low blood sugar overnight, have a snack before bed.

    You may wake up when you have low blood sugar, but you shouldnt rely on that. A continuous glucose monitor can alert you with an alarm if your blood sugar gets low while youre sleeping.

    Other things to know about hypoglycemia:

    It takes time for blood sugar to rise after eating, and its important to give your first treatment time to work. Use the table above to guide your treatment and timing instead of eating until you feel better, which will almost always lead to eating too much.

    Hypoglycemia can be common with certain types of exercise. Managing blood sugar during and after physical activity is important and is something that a lot of people with T1D have questions about. JDRF has a number of resources available for people with T1D and their families, many of which can be found here.

    Warning Signs Of Low Blood Sugar

    Why does my sugar level drop so drastically after I eat ...

    Hypoglycemia can cause both short- and long-term complications. Know the signs so that you can treat the condition as soon as youre aware of it.

    As a person living with diabetes, you know how important it is to reduce blood sugar when it is too high, a phenomenon called hyperglycemia. But blood sugar that is too low, or hypoglycemia, is equally critical to avoid.

    Hypoglycemia happens when the amount of blood glucose drops to a level thats too low to sustain normal functioning, says Erin Palinski-Wade, RD, CDCES, who is based in Sparta, New Jersey. In most people, this is defined as a blood sugar level at or below 70 milligrams per deciliter .

    Hypoglycemia is common among people with type 2 diabetes, according to a review published in June 2015 in the journal PLoS One. Individuals with the condition had an average of 19 mild or moderate episodes of hypoglycemia per year and nearly one severe episode per year on average, according to the researchers. Low blood sugar was particularly common among those taking insulin.

    This decrease in blood sugar levels can cause both short-term complications, like confusion and dizziness, as well as more serious issues, including seizures, coma, and, rarely, death, according to the American Diabetes Association .

    Hypoglycemia is usually the result of a too-high dose of insulin or a change in diet or exercise habits, according to Harvard Health Publishing.

    Who Gets Low Blood Sugar

    Low blood sugar can happen in people with prediabetes or diabetes, according to Mayo Clinic. If you are on insulin, it can happen if you take more insulin than you need, skip a meal, or eat fewer carbohydrates than usual without adjusting insulin. If you are not on insulin, or have diabetes but do not know it, low blood sugar can also happen if you skip a meal. It can also happen if you exercise more than usual.

    Low blood sugar is also more likely after eating meals that are high in starches and sugars because these are types of carbohydrates that raise blood sugar levels quickly. The effect is greater if the meal is low in protein, fat, and fiber, since those nutrients slow digestion and prevent blood sugar from swinging so wildly.

    What Are The Signs Of Hypoglycemia

    An individual may frequently wake up in the middle of the night as a result of nighttime hypoglycemia. In other instances, though, people may know if they experienced hypoglycemia during their sleep if they notice the following symptoms:

    • Waking up with a headache
    • Waking up in a sweat
    • Getting unusual feelings of tiredness throughout the day
    • Experiencing anxiety or heart palpitations
    • Feeling confused, dizzy or weak

    Whether you were recently diagnosed with type 2 diabetes or have been living with the condition for several years, you know how fickle blood sugar levels can be, and how important it is that they stay controlled.

    Proper blood sugar control is key for warding off potential diabetes complications, such as kidney disease, nerve damage, vision problems, stroke, and heart disease, according to the National Institutes of Health . Plus, keeping your levels in check on a daily basis can help you stay energized, focused, and in a good mood, explains Lisa McDermott, RD, CDCES, a diabetes specialist with the Pittsburgh-based Allegheny Health Network.

    According to the American Diabetes Association , proper medication, effective meal planning, regular exercise, and regular blood sugar checks can all help you keep your levels within a healthy range. The ADA recommends blood glucose stay within 80 to 130 milligrams per deciliter before meals and below 180 mg/dL two hours after the start of a meal. Furthermore, the organization recommends getting an A1C test, which measures your average blood glucose over the past two to three months, at least twice per year if your levels are stable and you are meeting treatment goals.

    What Drinks And Foods Raise Blood Sugar Fast

    • 4 teaspoons of sugar
    • 1/2 can of regular soda or juice

    Many people like the idea of treating low blood sugar with dietary treats such as cake, cookies, and brownies. However, sugar in the form of complex carbohydrates or sugar combined with fat and protein are much too slowly absorbed to be useful in acute treatment.

    Once the acute episode has been treated, a healthy, long-acting carbohydrate to maintain blood sugars in the appropriate range should be consumed. Half a sandwich is a reasonable option.

    If the hypoglycemic episode has progressed to the point at which the patient cannot or will not take anything by mouth, more drastic measures will be needed. In many cases, a family member or roommate can be trained in the use of glucagon. Glucagon is a hormone that causes a rapid release of glucose stores from the liver. It is an injection given intramuscularly to an individual who cannot take glucose by mouth. A response is usually seen in minutes and lasts for about 90 minutes. Again, a long-acting source of glucose should thereafter be consumed to maintain blood sugar levels in the safe range. If glucagon is not available and the patient is not able to take anything by mouth, emergency services should be called immediately. An intravenous route of glucose administration should be established as soon as possible.

    What Are Some Tips To Prevent Nighttime Blood Sugar Level Dips

  • Check your level before bed. According to Sulay Shah, M.D., a board certified endocrinologist, the only way to know if you are at risk is to monitor your blood glucose levelsas there arent always telltale signs.If you check and you notice that your levels are close to 70 mg/dL at bedtime, then you know you might be at risk, Dr. Shah says. In this case, he recommends eating some complex carbohydrates, like a peanut butter sandwich, an apple with peanut butter or one slice of multigrain toast with some avocado.
  • Dont skip dinner. If you arent eating dinner, Dr. Shah advises skipping your rapid-acting insulin or medicine, like glipizide or glimepiride, that can decrease your blood sugar levels. The goal here is to match your meal and medication, he says.
  • Monitor your alcohol intake. If you notice that your blood sugar is dropping after having a few beers or vodka sodas, then Dr. Shah warns that you may need to try to eat complex carbohydrates with the alcohol. Dr. Shah notes that blood sugar tends to drop 3 to 4 hours after drinking alcohol. When you regularly drink alcohol, you are decreasing the amount of stored glucose in the liver which helps to maintain a blood sugar in normal range, he explains.
