What To Take For Low Blood Sugar


What Are The Signs And Symptoms Of Hypoglycemia

How long does it take to lower blood sugar?

Hypoglycemia tends to present as a cluster of symptoms, and they often occur together. The most common signs of dangerously low blood sugar include:

  • Dizziness, disorientation, light-headedness, and an inability to think clearly
  • Hunger, especially if youve just eaten
  • Heightened irritability, confusion, and anxiety
  • Clamminess and sweating, with cold hands and feet
  • Drastic mood swings

If you have one or more of these symptoms contact your doctor.

When Your Blood Sugar Gets Low

Check your blood sugar whenever you have symptoms of low blood sugar. If your blood sugar is below 70 mg/dL, treat yourself right away.

1. Eat something that has about 15 grams of carbohydrates. Examples are:


  • 3 glucose tablets
  • One half cup of fruit juice or regular, non-diet soda
  • 5 or 6 hard candies
  • 1 tablespoon or 15 mL of sugar, plain or dissolved in water
  • 1 tbsp of honey or syrup

2. Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain.

3. Check your blood sugar again.

4. If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL , eat another snack with 15 g of carbohydrates.

You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range — over 70 mg/dL — and your next meal is more than an hour away.

Ask your provider how to manage this situation. If these steps for raising your blood sugar do not work, call your doctor right away.


Faq: Frequently Asked Questions

Who is most at risk for hypoglycemia? Aside from diabetics, Dr. Jennifer Shine Dyer notes that children are more prone toexperience episodes of hypoglycemia because of their smaller body size, as well as having less fat to burn to maintain energy when glucose levels are low. Eating meals every 4 to 6 hours should maintain glucose levels if this is the only cause of hypoglycemia, she says.

How do I know it’s low blood sugar? To know if you’re suffering from hypoglycemia, you’ll need to begin tracking your glucose levels under the supervision of your doctor. Drugstores and pharmacies carry test strips, as well as glucose meters, which will help. You can even see the effect that different foods have on your body by checking your blood sugar after eating.

Does fasting affect my blood sugar levels? Yes, going without food can trigger hypoglycemia. If you have diabetes and are concerned about hypoglycemia, aim to eat smaller, more frequent meals and snacks that are low in processed sugars every three hours or so.

Does alcohol consumption trigger low blood sugar?Excessive alcohol consumption, defined as more than one drink per day for women and more than two drinks per day for men, especially with little food, can keep your liver from releasing glucose, which can lead to hypoglycemia.

The Effects Of Low Blood Sugar On Your Body

Every cell in your body needs energy to function. The main source of energy might come as a surprise: Its sugar, also known as glucose. Blood sugar is essential to proper brain, heart, and digestive function. It even helps keep your skin and vision healthy.

When your blood sugar levels fall below the normal range, its called hypoglycemia. There are many identifiable symptoms of low blood sugar, but the only way to know if you have low blood sugar is by taking a blood glucose test.

Learn more about the symptoms of low blood sugar, as well as the long-term effects on the body.

most common reasons for low blood sugar are some medications used to treat diabetes, such as insulin.

In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesnt make enough insulin, or your body cant use it properly. Too much insulin or oral diabetic medication can lower the blood sugar level, leading to hypoglycemia.


However, contrary to popular belief, low blood sugar isnt exclusive to diabetes, though it is rare. It can also happen if your body makes more insulin than it should.

Another possible cause of low blood sugar is drinking too much alcohol, especially over long periods of time. This can interfere with the livers ability to create a buildup of glucose and then release it into your bloodstream when you need it.

Other causes include:

What Happens If Blood Sugar Gets Too Low While Sleeping

Having nightmares, crying out in your sleep, or experiencing other sleep disruptions are all possible when your blood sugar levels decrease during the night. Low blood sugar can cause symptoms such as lack of coordination, cold, clammy skin, and excessive perspiration.

How To Treat A Low Blood Sugar Level Yourself

Follow these steps if your blood sugar level is less than 3.5mmol/L or you have hypo symptoms:

  • Have a sugary drink or snack like a small glass of fizzy drink or fruit juice, 4 to 5 jelly babies, 3 to 6 glucose tablets or 1 to 2 tubes of glucose gel.
  • Test your blood sugar after 10 minutes if it’s improved and you feel better, move on to step 3. If there’s little or no change, treat again with a sugary drink or snack and take another reading after 10 to 15 minutes.
  • You may need to eat your main meal if it’s the right time to have it. Or, have a snack that contains a slow-release carbohydrate, such as a slice of bread or toast, a couple of biscuits, or a glass of cows’ milk.
  • You do not usually need to get medical help once you’re feeling better if you only have a few hypos.


    But tell your diabetes team if you keep having hypos or if you stop having symptoms when your blood sugar level is low.

    Other Causes Of Low Blood Sugar

    While low blood sugar is often associated with diabetes, it can also be affected by other factors. According to Dr. Danine Fruge, Medical Director of the Pritikin Longevity Center in Miami, Florida, the causes of blood sugar problems can include not only “diabetes, prediabetes , reactive hypoglycemia or other health issues, but also by not eating enough, taking too much insulin or even taking certain diabetes medications.”

    Other medications can also cause hypoglycemia, like quinine, or Qualaquin, which is used to treat malaria, or various medications for kidney failure. Exercising more than usual can also cause it, especially while taking such medications.

    Some other potential causes for low blood sugar include:


    • Heavy drinking without eating
    • Eating without ingesting enough carbohydrates
    • Eating fewer carbs than usual without reducing insulin amounts, or improper balancing of liquid/solid carbs and timing of insulin
    • Hormone deficiencies due to adrenal or pituitary tumor disorders, or in children without sufficient growth hormone
    • Long-term starvation, such as that which can occur with anorexia nervosa
    • Serious illness like hepatitis, kidney disorders and liver disease
    • Pancreatic tumors that make the body secrete too much insulin

    How Many Glucose Tablets Should I Take

    Diabetes Mellitus is a disorder that disrupts the way your body uses sugar. Sugar is used by your body to create and utilize energy in order for your cells to perform. Your body requires the perfect level of blood sugar in order to run smoothly. Otherwise, too high or too low blood sugar levels cause problems.

    How Insulin affects blood sugar levels

    Sugar gets into each cell with the help of a hormone called, insulin. Insulin is the key that opens the door to cells that allow sugar to enter. If there is not enough insulin, or your body stops responding to insulin, then you are left with a buildup of sugar in the blood. This buildup of sugar in the blood is called hyperglycemia. This is what happens when you have diabetes your blood sugar levels rise due to the fact that insulin is not helping the sugar molecules enter your cells. Your blood sugar levels may also fall to dangerous levels due to many factors. Too low of blood sugar is called hypoglycemia. If diabetics have to monitor blood sugar levels, one might ask how much sugar is allowed or even recommended?

    What Causes Low Blood Sugar

    A Day in the Life of Type 1 Diabetes Take Insulin Low ...

    Despite advances in the treatment of diabetes, low blood sugar episodes occur as a side effect of many treatments for diabetes. In fact, these episodes are often the limiting factor in achieving optimal blood sugar control, because many medications that are effective in treating diabetes carry the risk of lowering the blood sugar level too much, causing symptoms. In large scale studies looking at tight control in both type 1 and type 2 diabetes, low blood sugars occurred more often in the patients who were managed most intensively. This is important for patients and physicians to recognize, especially as the goal for treating patients with diabetes becomes tighter control of blood sugar.

    While people who do not have any metabolic problems can complain of symptoms that resemble low blood sugar, true hypoglycemia usually occurs in people with diabetes mellitus . People with pre-diabetes or insulin resistance also can have low blood sugars on occasion if their high circulating insulin levels are further challenged by a prolonged period of fasting. There are other rare causes for the condition, such as insulin-producing tumors and certain medications.


    These uncommon causes of hypoglycemia will not be discussed in this article, which will primarily focus on the condition occurring with type 1 or 2 diabetes and its treatment.

    • medicines that can treat symptoms of low blood glucose in people with hypoglycemia unawareness
    • educational approaches to reduce fear of low blood glucose, which can make it harder for you to control your diabetes

    Causes Of Blood Sugar Levels

    Whilst the liver and muscles produce some glucose, most comes from the foods we eat. Food and drinks that are high in carbohydrates are most impactful on blood sugar level. What we eat provides us most of the nutrients our body needs and sometimes, does not need. That is not to say that food is a major cause of blood sugar level increasing or decreasing too dramatically.


    Typically, if a person has health conditions or poor nutrition, this will lead to a spike or decline in blood sugar level. The causes differ from high to low blood sugar levels and are as follows:

    What To Do When Your Blood Sugar Levels Drop Too Low

    People who use insulin and other diabetes medications are at risk for hypoglycemia. Keep this action plan handy so you’re prepared.

    If you take insulin or diabetes medication, you may be at risk of developing hypoglycemia, or low blood sugar. Without quick attention, hypoglycemia can lead to serious complications, so its important to know what to do if it happens to you or someone close to you.

    In very severe cases, hypoglycemia can lead to seizures or loss of consciousness, says a clinical assistant professor of medicine, endocrinology, gerontology, and metabolism at Stanford Health Care, and chief of the Stanford Endocrine Clinic.

    It’s possible to have hypoglycemia but have no symptoms, according to the National Institute of Diabetes and Digestive and Kidney Diseases . On the other hand, symptoms can also come on rapidly. While symptoms vary from person to person, if you develop mild to moderate low blood sugar you may:

    • Feel shaky or jittery
    • Have a headache or be lightheaded
    • Turn pale
    • Be irritable or combative
    • Have blurred vision or see double

    Some people feel tingling or numbness in their extremities too, says Rodolfo Galindo, MD, an assistant professor of medicine in the division of endocrinology, metabolism, and lipids at the Emory University School of Medicine in Atlanta, and chair of the inpatient diabetes taskforce.

    No Symptoms Be Alarmed

    Low Blood Sugar

    Surprisingly, the most dangerous episodes of hypoglycemia occur with little or no warning. When low blood glucose occurs on a regular basis, the body can become used to the warning signs and the person may stop noticing symptoms. This is a particularly dangerous condition known as hypoglycemic unawareness. People with this condition might not realize they have low blood glucose until it’s dangerously low seizures and coma are sometimes the first indication of a problem. The good news is that this condition can often be reversed allowing people to once again notice the signs of low blood glucose if hypoglycemia is avoided for a few weeks through careful monitoring of blood glucose.

    What Is A Severe Low

    A severe low is defined as hypoglycemia that a person is unable to treat themselves. That is, they cant recognize that they are low and treat it with a fast-acting carbohydrate. If you sleep alone, and there is no one to help you recognize a low, it is generally recommended that you maintain a higher average blood sugar overnight if severe lows are a risk.

    Lows can happen in type 1 and type 2 diabetes. The inability to recognize a low is more common if you have longstanding diabetes. For more information about why you should be concerned about low blood sugars, read Lori Berards expert blog.

    Treatment For High Blood Sugar Levels

    For those with high blood sugar levels, it is vital to keep track of your blood sugars at home on a daily basis. This can be done with a glucose meter. These test monitors are often provided to diabetic patients so that they can manage their blood sugar levels at home everyday. They are available to purchase online if you are non-diabetic but wish to check on your levels regularly for safety.

    Diabetic patients can be prescribed medications to help with insulin levels when their blood sugar is high. Those with type 1 diabetes will be prescribed medication which needs to be taken several times daily. This type of diabetes has no cure but can be managed with the right medication.

    Those with type 2 diabetes or gestational diabetes can treat their high blood sugar with a change in diet or exercise. A healthier balanced diet is usually advised and sometimes, insulin medication is also prescribed if the blood sugar level becomes abnormally higher than the high reading for diabetic patients.
