What You Need to Know About Blood Sugar
Blood sugar, also known as glucose, is the main source of energy for your body. It comes from the food you eat, and your body uses it to power your cells, tissues, and organs.
The level of glucose in your blood is controlled by a hormone called insulin. Insulin is produced by the pancreas, and it helps glucose get into your cells. When your blood sugar level is too high, your pancreas releases insulin to lower it. When your blood sugar level is too low, your pancreas releases glucagon to raise it.
Blood sugar levels can fluctuate throughout the day, but they should generally stay within a certain range. The normal range for blood sugar levels is between 70 and 110 mg/dL (milligrams per deciliter).
If your blood sugar levels are too high or too low, you can experience a number of symptoms, including:
* Fatigue
* Hunger
* Thirst
* Frequent urination
* Blurred vision
* Headaches
* Dizziness
* Confusion
High blood sugar levels can also lead to long-term health problems, such as:
* Heart disease
* Stroke
* Kidney disease
* Eye damage
* Nerve damage
Low blood sugar levels can also lead to health problems, such as:
* Seizures
* Coma
* Death
If you have any of the symptoms of high or low blood sugar, it is important to see your doctor right away.
There are a number of things you can do to keep your blood sugar levels in a healthy range, including:
* Eating a healthy diet that is low in sugar and refined carbohydrates
* Getting regular exercise
* Maintaining a healthy weight
* Taking medication, if necessary
If you have diabetes, it is important to follow your doctor's instructions for managing your blood sugar levels. This may include taking medication, eating a healthy diet, and getting regular exercise.
