High Blood Sugar and Low Blood Sugar

by

Blood sugar, also known as blood glucose, is a crucial component of our body’s metabolism. It is the main source of energy for our cells, tissues, and organs. However, when blood sugar levels become too high or too low, it can lead to serious health problems.

In this article, we will discuss what level of blood sugar is dangerous and the potential consequences of high or low blood sugar levels. We will also discuss the symptoms, causes, prevention, and treatment of high and low blood sugar levels, as well as global statistics and the complications that can arise from abnormal blood sugar levels.

Normal Blood Sugar Levels

Blood sugar normal level are considered to be between 70 and 100 mg/dL (milligrams per deciliter) when fasting, and less than 140 mg/dL two hours after a meal. These levels can vary depending on factors such as age, sex, and overall health. It is important to note that even if your blood sugar levels fall within the normal range, it does not mean that you do not have pre-diabetes or diabetes. It is crucial to consult with a healthcare professional to determine your overall risk and to monitor your blood sugar levels regularly.

Dangerous Blood Sugar Levels

Blood sugar levels that fall outside of the normal range can be dangerous. High blood sugar levels, also known as hyperglycemia, can occur in individuals with diabetes or pre-diabetes. A blood sugar level of 200 mg/dL or higher is considered high and can lead to serious health problems such as heart disease, kidney damage, and nerve damage. High blood sugar levels can also lead to the development of diabetic ketoacidosis, a condition in which the body produces high levels of ketones, which can be fatal if left untreated.

 

On the other hand, low blood sugar levels, also known as hypoglycemia, can occur in individuals with diabetes or those taking certain medications. A blood sugar level of 70 mg/dL or lower is considered low and can lead to symptoms such as shakiness, dizziness, and confusion. In severe cases, low blood sugar levels can lead to unconsciousness. Low blood sugar levels can also occur during the night, which is known as nocturnal hypoglycemia, it can lead to night sweats, nightmares, or even seizures.

Symptoms of High Blood Sugar

When an individual has high blood sugar levels, they may experience a variety of symptoms. These symptoms can include:

● Fatigue: High blood sugar levels can cause fatigue and a lack of energy due to the body not being able to effectively use glucose as a source of energy.
● Excessive thirst: High blood sugar levels can cause an individual to feel thirsty more frequently.
● Frequent urination: High blood sugar levels can cause an individual to urinate more frequently as the body tries to remove the excess glucose from the bloodstream.
● Blurred vision: High blood sugar levels can cause fluid to build up in the eyes, leading to blurred vision.
● Slow wound healing: High blood sugar levels can affect the body’s ability to heal wounds and can make an individual more susceptible to infections.

Symptoms of Low Blood Sugar

When an individual has low blood sugar levels, they may experience a variety of symptoms. These symptoms can include:

● Shakiness: Low blood sugar levels can cause an individual to feel shaky or jittery.
● Dizziness: Low blood sugar levels can cause an individual to feel lightheaded or dizzy.

● Diabetes is a condition in which the body is unable to produce or properly use insulin, which can lead to high blood sugar levels.
● Obesity can increase an individual’s risk of developing diabetes and can contribute to high blood sugar levels.
● Certain medications such as steroids and certain antidepressants can cause high blood sugar levels.
● Stress can cause the release of hormones that can affect blood sugar levels.
● A diet high in sugar and refined carbohydrates can contribute to high blood sugar levels.
● Lack of physical activity can contribute to the development of obesity and diabetes, which can lead to high blood sugar levels.

Causes of Low Blood Sugar

Several factors can contribute to low blood sugar levels. These include:

● Diabetes can cause low blood sugar levels if an individual takes too much insulin or misses a meal.
● Certain medications such as insulin and sulfonylureas can cause low blood sugar levels.
● Consuming alcohol can cause low blood sugar levels, especially when consumed on an empty stomach.
● Skipping meals can cause low blood sugar levels as the body does not have enough glucose to function properly.
