Can You Die From Low Blood Sugar


When Is It Necessary To Call A Doctor If You Have Diabetes

  • If you have diabetes and your blood sugar is 300 mg/dL or higher two times in a row for an unknown reason.
  • If you have a low blood sugar that has not come up after three treatments, call your healthcare provider or 911.
  • If you see a person with diabetes who appears confused, they may be having a low blood sugar episode. Left untreated, the low blood sugar could lead to a diabetic coma. If the person is still able to follow instructions, give him or her something to drink or eat and call for an ambulance or 911.
  • If you see someone with diabetes become unresponsive, call 911.

If you do call 911, let the responders know that the person has diabetes if theyre not able to communicate. If you do have diabetes, you may want to wear a medical identification item like a bracelet or necklace.

When you are taken to a healthcare facility, providers will do a physical examination and take blood to determine levels of glucose, ketones and other substances.

What Is Severe Hypoglycemia

Hypoglycemia can be mild, moderate, or severe based on the persons blood glucose and condition. Here are the levels:

  • Level 1 hypoglycemia: Blood glucose is less than 70 mg/dL but is 54 mg/dL or higher.
  • Level 2 hypoglycemia: Blood glucose is less than 54 mg/dL.
  • Level 3 hypoglycemia: A person is unable to function because of mental or physical changes. They need help from another person. In this case, blood glucose is often below 40mg/dL.

Signs And Symptoms Of Low Blood Sugar

Each person’s reaction to low blood sugar is different. Learn your own signs and symptoms of when your blood sugar is low. Taking time to write these symptoms down may help you learn your own symptoms of when your blood sugar is low. From milder, more common indicators to most severe, signs and symptoms of low blood sugar include:


  • Feeling shaky
  • Color draining from the skin
  • Feeling sleepy
  • Feeling weak or having no energy
  • Blurred/impaired vision
  • Tingling or numbness in the lips, tongue or cheeks
  • Headaches
  • Nightmares or crying out during sleep
  • Seizures

The only sure way to know whether you are experiencing low blood sugar is to check your blood sugar, if possible. If you are experiencing symptoms and you are unable to check your blood sugar for any reason, treat the hypoglycemia.

A low blood sugar level triggers the release of epinephrine , the fight-or-flight hormone. Epinephrine is what can cause the symptoms of hypoglycemia such as thumping heart, sweating, tingling and anxiety.

If the blood sugar level continues to drop, the brain does not get enough glucose and stops functioning as it should. This can lead to blurred vision, difficulty concentrating, confused thinking, slurred speech, numbness, and drowsiness. If blood sugar stays low for too long, starving the brain of glucose, it may lead to seizures, coma and very rarely death.

Causes Of Low Blood Sugar

In people with diabetes, the main causes of low blood sugar are:


  • taking too much diabetes medicine especially too much insulin, medicines called sulphonylureas or medicines called glinides
  • skipping or delaying a meal
  • eating less carbohydrate-containing food than usual, such as bread, cereals, pasta, potato and fruit
  • exercise or activity, especially if it’s intense or unplanned
  • binge drinking or drinking alcohol on an empty stomach

Sometimes there’s no obvious reason why low blood sugar happens.

Very occasionally, it can happen in people who don’t have diabetes – see section on low blood sugar without diabetes.

What Causes Low Blood Glucose In People With Diabetes

How Low Can Blood Sugar Go Before You Die

Low blood glucose levels can be a side effect of insulin or some other medicines that help your pancreas release insulin into your blood. Taking these can lower your blood glucose level.

Two types of diabetes pills can cause low blood glucose

  • sulfonylureas, usually taken once or twice per day, which increase insulin over several hours
  • meglitinides, taken before meals to promote a short-term increase in insulin

    What Are The Risk Factors For Diabetic Coma

    While anyone who has diabetes is at risk for a diabetic coma, the causes depend on the type of diabetes:

    • People with Type 1 diabetes have a greater chance of going into a diabetic coma as a result of diabetic ketoacidosis or hypoglycemia. This is because people with Type 1 diabetes always need insulin and have a wider range in their blood glucose levels than people with Type 2 diabetes.
    • People with Type 2 diabetes have a greater chance of going into a diabetic coma from diabetic hyperosmolar syndrome than from diabetic ketoacidosis or hypoglycemia.

    Other risks that can lead to diabetic coma in anyone who has diabetes include:

    • Surgery.

    Treating Low Blood Glucose If You Take Medicines That Slow Down Digestion

    Some diabetes medicines slow down the digestion of carbohydrates to keep blood glucose levels from rising too high after you eat. If you develop low blood glucose while taking these medicines, you will need to take glucose tablets or glucose gel right away. Eating or drinking other sources of carbohydrates wont raise your blood glucose level quickly enough.

    What If Im Experiencing Hypoglycemic Episodes Even Though My Doctor Has Confirmed That Im Not Diabetic Or Prediabetic

    If you have low blood sugar and dont have diabetes or prediabetes, it can be a sign of another serious health issue such as a tumor, hormone deficiency, kidney disorder, anorexia, or other eating disorder, all of which can cause dangerously low blood sugar.

    Anorexia has the highest mortality of any psychiatric disorder, and the cause of death can be hypoglycemia, so take your illness seriously and seek help if you suspect your eating disorder may be progressing to the point where it is causing you to faint or experience other signs and symptoms of dangerously low blood sugar. The National Eating Disorders Association has resources on how to identify the signs that you may have an eating disorder, a hotline for help, as well as easily accessible information on everything from how to know when you need help to how to find quality treatment options in your zip code.

    People who are not diabetic don’t spontaneously have hypoglycemia for no reason, explains Dr. Christofides. Its often an indication of another underlying issue, such as a hormone deficiency or eating disorder, so its important to schedule an appointment with your doctor to determine the cause in order to prevent complications.

    Common causes of hypoglycemia in people without diabetes include:


    • Pancreatic tumor
    • Medication that inhibits the proper production of insulin
    • Hepatitis or kidney disorders
    • Hormone deficiencies
    • Anorexia and other eating disorders

    How Is Hypoglycemia Treated If I Lose Consciousness

    Low Blood Sugar from This is Exactly What Happens to Your ...

    Severe blood sugar drops can cause you to pass out. This is more likely in people with type 1 diabetes but can also happen in people with type 2 diabetes treated with insulin. This can be a life-threatening. Its important to educate your family, friends, and even coworkers on how to administer a glucagon injection if you lose consciousness during a hypoglycemic episode. Glucagon is a hormone that stimulates the liver to break down stored glycogen into glucose. Talk to your doctor to see if you need a prescription for a glucagon emergency kit.

    The best way to avoid hypoglycemia is by following your treatment plan. A diabetes control plan to prevent hypoglycemic and hyperglycemic episodes includes managing:

    • diet
    • medication

    If one of these is off balance, hypoglycemia can occur.

    The only way to know your blood sugar levels is to test your blood sugar. If you use insulin to control your blood sugar, you should check blood sugar levels four or more times per day. Your healthcare team will help you decide how often you should test.

    If your blood sugar levels arent in the target range, work with your team to change your treatment plan. This will help you identify what actions might lower your blood sugar suddenly, such as skipping a meal or exercising more than usual. You shouldnt make any adjustments without notifying your doctor.

    Low Blood Sugar Tied To Death Risk In Hospitalized

    Association was seen even if patient did not have diabetes

    HealthDay Reporter

    THURSDAY, Nov. 17, 2016 — Hospital patients with low blood sugar may be at increased risk for death, a new study from Israel suggests.

    The study included nearly 3,000 patients with low blood sugar . Nearly 32 percent died by the end of the follow-up period.


    For patients with moderate hypoglycemia, the risk of death was higher among those taking insulin than among those not taking insulin. For those with severe hypoglycemia, death risk was the same in both groups.

    The reason for hospital admission had no effect on the association between blood sugar levels and death risk, according to the study.

    It was published Nov. 17 in the Journal of Clinical Endocrinology & Metabolism.

    “Hypoglycemia is common among hospitalized patients with and without diabetes mellitus. Our findings suggest that hypoglycemia, whether insulin-related or non-insulin related, is associated with short- and long-term mortality risk,” said senior study author Dr. Amit Akirov, from Rabin Medical Center in Israel.

    “These data are a timely reminder that hypoglycemia of any cause carries the association with increased mortality,” Akirov said in a journal news release.


    However, the study did not prove that low blood sugar causes death risk to rise.

    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.
