What is Dangerously Low Blood Sugar: Symptoms, Causes and Treatment

It’s no secret that too high blood sugar or glucose can be harmful to health. Conversely, too low blood sugar levels can also trigger a variety of health disorders. And you are obliged to know this article because it will discuss What is Dangerously Low Blood Sugar: Symptoms, Causes and Treatment.

What is Dangerously Low Blood Sugar?

Where the condition of the body when blood sugar is too low is known as hypoglycemia in the medical world. Hypoglycemia is not a term for a disease but can indicate health problems.

All body cells, including the brain, need the energy to function properly. Meanwhile, glucose serves to supply energy to the body and the hormone insulin helps to absorb and use such energy.

Too low blood sugar causes extreme hunger, shaking, heart palpitations, nausea, and sweating. In severe cases, hypoglycemia can lead to coma and death.

Hypoglycemia can occur as a result of reactions to medications, such as insulin. This condition is prone to occur in diabetics who use treatment methods with insulin therapy. A person can be said to have hypoglycemia if his glucose levels are below 70 milligrams per deciliter.

What is a dangerously low blood sugar number?

Blood sugar levels are called low if less than 70 milligrams per deciliter and this is rare in healthy people. Hypoglycemia can be quickly overcome just by eating something.

However, keep in mind that what you eat, matters. If a person has diabetes then it is advisable to drink the juice. For the healthy, it is advisable to infiltrate carbohydrate source foods. Add protein consumption such as peanut butter, so that blood sugar levels are immediately stable.

Usually, blood sugar levels often drop, occurring in people whose portion of food is very small, less than the amount of energy they expend daily. Eat-in a balanced portion, that’s the key to keeping blood sugar levels normal.

Which Is More Dangerous, Blood Sugar Too High or Too Low?

A person’s blood sugar levels can be high, but can also below, depending on their lifestyle and diet. Which is more dangerous?

Blood sugar is medically the definition of the amount of sugar content or glucose substances in the blood. Maintaining sugar levels in the body is not only important for diabetics, but also for healthy people.

Because normal blood sugar levels are important for your body’s performance and health. If it is too high or too low, there will be a disturbing complaint. Know which conditions are more dangerous so you can be more alert.

When blood sugar is too high

According to experts or doctors, blood sugar levels are said to be too high when exceeding the figure of 200 mg / dL. This can occur in 2 conditions, namely when your body does not have enough insulin or when your body cannot use insulin properly.

Doctors usually refer to the first condition with type 1 diabetes. Because of the insufficient amount of insulin in the body, there is a build-up of sugar in the blood.

It is this condition that then leads to severe life-threatening complications, such as diabetic ketoacidosis and hyperglycemic hyperosmolar. Symptoms range from easy drowsiness to loss of consciousness and coma.

Meanwhile, the second condition is called type 2 diabetes, caused by improper lifestyles, such as drinking alcohol, consumption of sweet foods, rarely exercising, and obesity.

As a result of this lifestyle, the insulin that should be tasked with lowering sugar in the blood becomes no longer sensitive to recognize the increase in blood sugar levels. As a result, there is a build-up in the blood.

That said, you don’t have to worry. If you have sufficient insulin levels and no impaired function of insulin, generally the body can keep blood sugar levels always below 200 mg / dL, even if you have just consumed a sweet food.

Then, what if the blood sugar is too low?

Too low blood sugar or hypoglycemia can occur when your blood sugar levels are below 70 mg/dL. Low blood sugar levels are at risk of causing various organs of the body to malfunction, especially in parts of the brain.

Because the brain is a very sensitive organ to low blood sugar levels because glucose is the main source of energy for the brain.

When you experience hypoglycemia, you will feel symptoms of dizziness, confusion, tired and weak body, headache, inability to concentrate, heart palpitations, cold sweats, vision impairment, seizures, to loss of consciousness up to coma.

If not treated immediately, hypoglycemia can also cause permanent brain damage. Usually, symptoms of severe hypoglycemia are often experienced by diabetics with the following habits:

  • The use of diabetes medications is not offset by proper carbohydrate intake.
  • Heavy physical activity but not balanced with the intake of foods that meet the needs of carbohydrates.
  • Fasting with improper nutrition management.

However, you who are able-bodied also need to be careful. Because hypoglycemia can also attack if you undergo long-term fasting without proper nutritional preparation. In addition, long-term food supply shortages in an area are also prone to hunger or starvation, resulting in a drastic drop in blood sugar.

Then what is a dangerously low blood sugar reading?

Blood sugar is too high or too low is basically equally dangerous if not immediately addressed. Both can also cause life-threatening complications.

The difference is that the symptoms of low blood sugar can be treated more easily when a person already feels the symptoms. The initial treatment that can be done at home is to eat or drink something sweet immediately.

The case of high blood sugar is more difficult to detect alone because it requires a complete lab examination, and the treatment must also be handled by a doctor in the hospital.

Whether your blood sugar is too high or too low, they’re both equally putting your life at risk. So, monitoring normal blood sugar levels is very important, especially for those who suffer from diabetes.

Check your blood sugar levels regularly, at least once every 6 months. However, especially for those of you who have diabetes, do a daily blood sugar record and make a note of it in your personal book, as a reminder to live a healthy lifestyle, maintain your intake, and exercise regularly.

Characteristic of what is dangerously low blood sugar level?

Blood sugar levels drop to below 70 mg/dL.

A person who has low blood sugar can be known with pale skin, a powerless body and fatigue, restlessness, irritability, cold sweats, tingling in the mouth area, and a rapid heartbeat.

A person with blood sugar levels too low to below 40 mg/dL can experience symptoms of difficulty concentrating, being unable to stand or walk, speech, muscle twitching, seizures, loss of consciousness, and even death.

Low blood sugar can be overcome by eating foods containing carbohydrates for healthy. In addition, plus proteins such as peanut butter so that blood sugar levels are stable again. Eat a balanced portion. As for diabetics, it is recommended to drink fruit juice or glucose tablets.

If you often have low blood sugar, immediately check with a doctor to make sure you have or do not have health problems that make blood sugar levels low.

How about dangerously low blood sugar in diabetics?

The condition of low sugar at night in diabetics is known as noctural hypoglycemia. In such conditions, diabetes blood sugar levels are less than 70 milligrams per deciliter (mg/dl). Usually, this condition occurs in the early hours of the morning.

This low blood sugar condition can harm diabetes if not treated immediately. Diabetics with hypoglycemia can experience loss of consciousness, seizures, severe brain disorders, and even death.

However, not all diabetics are susceptible to nocturnal hypoglycemia. This condition is prone to occur when:

  • Diabetes is experiencing severe pain, causing his blood sugar levels to be unstable
  • Diabetic insulin users eat too little in the afternoon and evening
  • Diabetes injects insulin in too large a dose then it should
  • Improper storage of insulin, e.g. insulin stored at overheating temperatures
  • Diabetes exercise too heavily before bedtime
  • Diabetics drink alcohol-containing beverages at night.

Generally, low blood sugar at night is characterized by complaints of restlessness or having nightmares while sleeping, heart palpitations, waking up with fatigue or headaches, or clothes and sheets wet with sweat when awakened. However, in some cases, the condition does not cause symptoms.

Therefore, diabetics who have a vulnerable condition of nocturnal hypoglycemia are advised to have a blood sugar test at around 2 am for 2-3 days.

What tools can we use at home to measure blood sugar?

The blood sugar test is done independently at home, using blood from the fingertips and the glucometer (digital blood sugar meter) itself. If diabetes has difficulty doing it yourself, ask family members for help at home.

The purpose of the examination is to see if the blood sugar levels of diabetes in the early morning are stable or tend to be at low levels.

What is Dangerously Low Blood Sugar

If the test results show low sugar levels, diabetes is recommended to consult a doctor again. This step is needed to determine whether the dose of anti-diabetes medication needs to be re-adjusted or food intake at night needs to be increased.

How to treat low blood sugar for diabetics?

If diabetes shows symptoms of low blood sugar such as palpitations, cold sweats, or the body feels very limp, it is best to immediately check your own blood sugar.

If the test results show that the blood sugar level is less than 70 mg/dl, diabetics should directly drink sugar water made by dissolving 2-3 tablespoons of granulated sugar into a glass of water or tea.

After 15 minutes, double-check your blood sugar levels. If blood sugar is still below 70 mg/dl, drink more sugar water with the same dose. Do so until blood sugar levels are normal. After that, consume snacks periodically so that the condition of hypoglycemia does not occur again.

Low blood sugar conditions in people with diabetes that occur at night should be watched out for. Because the condition is often undetectable and can lead to fatal complications.

In order to prevent it, diabetes is recommended to check its own blood sugar periodically, especially at night. If the blood sugar level is shown tends to below, then the condition can be resolved immediately.

Tips to overcome low blood sugar levels


Honey can provide rapid glucose injections. It is also digested and absorbed into the blood. Take a tablespoon of honey when you feel your blood sugar levels drop.

Sugar or candy

Sugar or sweets can provide a rapid supply of glucose to the body. This can be the best way to increase blood sugar levels because it is easy to digest.

Avoid artificial sweeteners

Artificial sweeteners do not contain calories, and they can not contribute to the level of sugar in the blood. You can replace it with honey or natural sugars in low quantities.
