The average person with type 1 diabetes may experience symptoms of low blood glucose up to two times a week. However, not all are aware that these symptoms can rapidly progress to seizures, coma and even death if hypoglycemia is severe. Though hypoglycemia can be common and occur repeatedly in some people with diabetes, symptoms of low blood glucose should always be taken seriously.

Before you test your blood sugar at home, its important to find out from your doctor what a healthy blood sugar range is for you. Your doctor will determine this range based on factors such as:

  • the type of diabetes you have
  • how long youve had diabetes
  • whether you have any other chronic health conditions

Possible Causes With Diabetes

Why Is Low Blood Sugar So Dangerous for People With Diabetes?

If you have diabetes, you might not make enough insulin. As a result, glucose tends to build up in the bloodstream and can eventually become dangerously high. To treat high blood sugar, you may be prescribed insulin or other medication to lower blood sugar levels.

However, too much insulin or other diabetes medications may cause your blood sugar level to drop too low, resulting in hypoglycemia. Hypoglycemia can also occur if you eat less than usual after taking diabetes medication, or if you exercise more than you normally do.

Plus, when youre on vacation or traveling, you may eat more, drink more alcohol, or be more active all of which can cause blood sugar swings. She advises checking your blood sugar more frequently while traveling to catch any concerning trends before they become serious problems.

McDermott also recommends packing healthy carb-balanced snacks as well as a refillable water bottle to help you stay hydrated. Try to eat something every four hours throughout the day, even if it cant be at the exact same times you usually eat. If you take insulin and you’re shifting time zones, be sure to work out a medication schedule with your diabetes care team before your trip so you don’t mistime any doses, she says.

Treatment By Medical Professionals

In a healthcare setting, treatment depends on the severity of symptoms and intravenous access. If a patient is conscious and able to swallow safely, food or drink may be administered, as well as glucose tabs or gel. In those with intravenous access, 25 grams of 50% dextrose is commonly administered. When there is no intravenous access, intramuscular or intra-nasal glucagon may be administered.

Treating An Episode Of Hypoglycaemia

Hypoglycaemia – How to Treat and Prevent Low Blood Sugar

The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.

For example, this could be:

  • a glass of fruit juice or non-diet soft drink
  • between three and five dextrose tablets
  • a handful of sweets

At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.

After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.

It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.

When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.

It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.

What Is The Long

The long-term outlook for people with an insulinoma is very good if the tumor is removed. After surgery, most people recover completely without complications. However, an insulinoma may return in the future. Recurrence is more common in people who have multiple tumors.

A very small number of people may develop diabetes after surgery. This usually only occurs when the entire pancreas or a large portion of the pancreas is removed.

Complications are more likely in people with cancerous insulinomas. This is particularly true when the tumors have spread to other organs. The surgeon may not be able to remove all the tumors completely. In this case, more treatment and follow-up care will be necessary. Luckily, only a small number of insulinomas are cancerous.

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 they’re doing, or by a trained healthcare professional.

You should dial 999 to request an ambulance if:

  • a glucagon injection kit isn’t available
  • there’s nobody available who’s trained to give the injection
  • the injection is ineffective after 10 minutes

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

If you’re 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.

Recognizing Hypoglycemia After Exercise

Because exercise can make it more difficult to recognize hypoglycemia, familiarize yourself with a broad range of symptoms of low blood sugar. They can vary from person to person, but in general, here’s what to look out for, according to the Cleveland Clinic:

  • Sudden, intense hunger
  • Blurred vision


If left untreated, severe cases of hypoglycemia can cause seizures, loss of consciousness and, in rare cases, death. If you are taking blood sugar-lowering medications, be sure to keep glucose tablets close at hand.

It’s important to raise low blood sugar levels right away to avoid complications. The ADA recommends treating low blood sugar by following the 15-15 rule:

  • Consume 15 grams of simple carbs .
  • Wait 15 minutes.
  • If your symptoms have not improved after 15 minutes, recheck your blood sugar. If your blood sugar levels are still too low, eat another 15 grams of carbs, then wait another 15 minutes. Call your doctor if your symptoms don’t improve after repeating the process.


The symptoms of dehydration are similar to those of low blood sugar, according to the Mayo Clinic. Be sure to drink plenty of water before, during and after exercise.

How Exercise Lowers Blood Sugar

Blood sugar, also called glucose, is the body’s main source of energy it mainly comes from the carbohydrates in food, according to Kaiser Permanente. The body regulates blood sugar levels with the help of the hormone insulin, which moves glucose out of the bloodstream and into the cells.

Exercise lowers blood sugar levels by increasing the body’s insulin sensitivity, aka its ability to use insulin, according to the American Diabetes Association . This helps the muscles get more glucose. Additionally, physical activity allows the cells to take in more glucose, whether insulin is available or not. This further reduces blood sugar.

Exercise also depletes the body’s glycogen stores, according to the Joslin Diabetes Center. When you eat, your liver stores some glucose in the form of glycogen for later use. During exercise, this glycogen is converted back into glucose for fuel. After exercise, it can take the body anywhere from four to 24 hours to replenish its glycogen stores, depending on the intensity of the activity. That means even if exercise doesn’t cause low blood sugar in the moment, it can increase the risk of hypoglycemia for people with diabetes for up to 24 hours after a workout.

Dr. Hafida says that exercise doesn’t pose a risk of hypoglycemia for people without diabetes. Even though a person without diabetes may sometimes âfeelâ the symptoms of low blood sugar, their blood glucose levels will usually still be within the normal range.

What Causes Blood Sugar To Drop Rapidly Apart From Too Much Insulin

Clearly, then, too much insulin is what causes blood sugar to drop rapidly. But theres more to it than simply taking too much insulin.

Skipping meals or eating less than what youre used to will also mean having too much insulin in the body.

In addition, the bodys sensitivity to insulin can change throughout the day. The greater the insulin sensitivity, the less insulin the body will need. If insulin sensitivity has increased, this will often be due to the combination of exercise and diabetes.

These are probably the most common reasons for low blood sugar, as the blog post What Happens when Blood Sugar is low? points out. NHS inform gives some other reasons, such as:

Fasting. Aside from not taking in any carbs for the insulin to displace, fasting can also lead to not having enough nutrients, which can hinder the bodys digestive abilities.

Similarly, illness can impact the bodys response to glucose. Illness will usually increase blood sugar but it depends on what kind of illness and how your body responds to it which can give low blood sugar. Read more on this topic with Diabetes and the Flu.

Meanwhile, sleep itself may not lower blood sugar, but you can still get low blood sugar in the night for the same reasons you would in in the day.

The only difference is that you cant treat it as effectively because youre well asleep. So, do have carbs ready by your bed, just in case. Read more on Diabetes and Sleep.
