What’s Wrong with Having High Blood Sugar?
Even when people are told during a health checkup, “Your blood sugar is high, so please see a doctor,” many think, “I don’t have any symptoms, so I’m probably still okay.”
In fact, diabetes is a disease that usually causes very few symptoms in its early stages.
As a result, it can progress unnoticed, and complications may already have developed by the time symptoms appear.
Why Is High Blood Sugar a Problem?
Sugar in the bloodstream is an important source of energy that our bodies need to function.
The sugar we obtain from food is used by cells to produce the energy needed to move and live.
However, too much sugar can harm the body.
To make this easier to understand, let’s think about everyday life.
For example, petroleum is a useful energy source that supports modern life. But if it is overused, it can cause air pollution and environmental damage.
Something similar happens inside the body.
When high blood sugar continues for a long time, blood vessels, nerves, and many other tissues throughout the body gradually become damaged. Excess sugar also combines with proteins in the body to form substances called advanced glycation end products (AGEs). These substances contribute to arteriosclerosis and tissue damage.
In a way, it is like “environmental pollution” slowly developing inside the body.
If this condition continues over time, it can eventually lead to a variety of complications.
Major Complications of Diabetes
Diabetes can cause conditions such as:
- Stroke
- Heart attack
- Kidney disease
- Diabetic retinopathy
- Nerve damage
Once these complications progress, it can be difficult to completely restore normal function.
For this reason, the most important goal of diabetes treatment is not simply treating symptoms after they appear, but preventing complications from developing in the first place.
Even Without Symptoms, Early Evaluation Is Important
Some people may wonder, “Do I really need to go to the hospital if I feel fine?”
However, the period before symptoms appear is actually the most important time to prevent future problems such as stroke or kidney disease.
If a health checkup shows abnormal blood sugar levels, it is important not to ignore the results and to consult a medical professional.
About Insulin Treatment
Depending on the condition, insulin therapy may sometimes be started from the beginning of treatment.
Some people think that “using insulin means the diabetes is severe,” but that is not always the case.
Insulin may be used temporarily to improve blood sugar levels quickly and allow the pancreas to rest. Once blood sugar control improves, some patients may be able to stop insulin or reduce their medications.
For this reason, there is no need to be overly afraid of insulin treatment.
In Closing
Diabetes is not a disease where “no symptoms means no problem.”
If you are told during a health checkup that your blood sugar is high, it is important to seek medical care early and take steps to prevent future complications.
