What Is Diabetes? From Symptoms to Blood Glucose Control

Many people think diabetes is something that won’t affect them. However, some individuals may have high blood sugar without any obvious symptoms, only realizing the severity when complications such as blurred vision or numbness in the hands and feet begin to appear. This article will quickly take you to understand diabetes common types, possible causes, and early symptoms. It will also teach you how to read blood glucose values and how to control them daily, helping you master your health status step by step.

What Is Diabetes?

Diabetes can be simply understood as "a problem with blood sugar regulation." Normally, the starches and sugars we eat are broken down into glucose and enter the bloodstream, then insulin helps transport them into cells to be converted into the energy the body needs. However, when insulin secretion is insufficient or the body's response to it worsens, this process gets stuck, and the sugar in the blood cannot be lowered, eventually forming high blood sugar. Over the long term, this not only makes one feel tired and thirsty but may also gradually affect the health of blood vessels and nerves.

What Are the Symptoms of Diabetes? Your Body Is Quietly Reminding You

Symptoms of diabetes are not necessarily obvious at first; many people experience changes unconsciously. For example, becoming particularly thirsty and wanting to drink water constantly, a significant increase in urination frequency, even being woken up by the urge to urinate at night; some people feel listless and tired all day, or lose weight continuously without intentionally controlling their diet.

In addition, some people may find that small wounds take a long time to heal, vision occasionally becomes blurred, or skin often feels itchy with recurring infections. These conditions may seem like minor issues individually, but if they persist for a while, one should be alert, as they are likely related to high blood sugar. It is recommended not to delay and to arrange an examination as soon as possible to clarify the cause for peace of mind.

There Is More Than One Type of Diabetes; Do You Know Which Types Exist?

Type 1 Diabetes

Type 1 diabetes is usually related to an autoimmune response, where the body's immune system mistakenly attacks the pancreatic cells responsible for producing insulin, resulting in insulin being almost unable to be secreted normally. Because the body lacks insulin, blood sugar is difficult to utilize, so patients need to maintain stability through daily insulin injections, and most are diagnosed during childhood or adolescence. For patients, regular medication and blood glucose monitoring are an indispensable part of daily life.

Type 2 Diabetes

Type 2 diabetes is the most common type and usually has a significant relationship with daily lifestyle habits. When the body's sensitivity to insulin decreases, which is known as "insulin resistance," or when the insulin secreted by the pancreas is insufficient, it causes blood sugar to rise slowly. Common risk factors include being overweight, prolonged sitting, a diet that is too sweet or high in fat, and family inheritance; therefore, adjusting lifestyle habits is the key to control and prevention.

Gestational Diabetes

Gestational diabetes refers to blood sugar abnormalities that appear only during pregnancy. This is mainly because hormonal changes during pregnancy make insulin less sensitive, leading to unstable blood sugar regulation. For most pregnant women, blood sugar gradually returns to normal after delivery; however, this experience also signifies that the body has undergone metabolic stress. Therefore, the risk of developing type 2 diabetes in the future is slightly higher than that of the general population. It is recommended to continue monitoring blood sugar after childbirth for peace of mind.

Other Specific Types of Diabetes

In addition to type 1, type 2, and gestational diabetes, there are some rarer specific types. These conditions may be related to genetic abnormalities, or they could be caused by problems with the pancreas itself, such as chronic pancreatitis affecting insulin secretion, or an imbalance in the endocrine system. Furthermore, some people who use specific medications long-term may also experience elevated blood sugar. The causes of this type of diabetes are more complex and usually require further examination and judgment by a physician to identify the true cause and treat it accordingly.

Diabetes Testing: How to Interpret Blood Sugar Values for Peace of Mind?

To determine if you have diabetes, you can check your blood sugar status through several types of blood tests, which can also help detect early if you are approaching prediabetes. The earlier you know the changes in your values, the better chance you have to bring blood sugar back under control through diet and lifestyle adjustments. Below are several common testing methods to help you more clearly understand your health status.

Fasting Plasma Glucose (FPG)

Fasting blood sugar is the most common and basic type of blood sugar test. It requires fasting starting from the previous night, with blood drawn after at least 8 hours of no food intake. Generally, a value below 100 mg/dL is within the normal range; if it is between 100 and 125 mg/dL, it means blood sugar is already slightly high, approaching prediabetes. When the value reaches or exceeds 126 mg/dL, further evaluation is needed, and clinically, the possibility of diabetes is often suspected.

Glycated Hemoglobin (HbA1c)

The glycated hemoglobin test can show the "average blood sugar status over the past 2 to 3 months." It does not fluctuate significantly based on whether you have eaten that day and is often used as an indicator for long-term blood sugar control. HbA1c values below 5.7% are normal; if they fall between 5.7% and 6.4%, it means blood sugar is already high, with a risk of prediabetes. If the value reaches 6.5% or above, further evaluation is required, and clinically, it may be diagnosed as diabetes. This test can more comprehensively reflect the body's blood sugar control status.

Random Blood Glucose Measurement

The biggest feature of random blood glucose testing is that it does not require fasting, making it fast and convenient. Blood can be drawn or blood sugar measured at any time, making it suitable for preliminary screening when blood sugar abnormalities are suspected. If the test result reaches or exceeds 200 mg/dL, and typical symptoms such as extreme thirst, drinking a lot of water, frequent urination, or unexplained weight loss also appear, one should be highly vigilant, and clinical evaluation for diabetes will be conducted.

How to Correctly Control Blood Sugar to Prevent Diabetes?

Develop Regular Exercise Habits

To stably control blood sugar, developing regular exercise habits is important! It is recommended to accumulate at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming. For higher-intensity exercise, you can adjust to at least 3 days per week, for about 20 minutes or more each time. Exercise not only helps control weight but also improves the body's sensitivity to insulin, making blood sugar easier to utilize; maintaining this in the long term is also very helpful for preventing complications.

Eat Right to Prevent Blood Sugar Spikes

Controlling blood sugar is not as simple as just eating fewer sweets; what you eat overall and how you pair foods is more important. For daily beverages, prioritize sugar-free or low-sugar options to reduce the intake of sugary drinks. For staple foods, refined starches like white rice, white bread, and noodles can be moderately reduced to prevent blood sugar from rising too quickly.

In your diet, you can add more vegetables to increase fiber and help stabilize absorption; switching staples to whole grains is even better, paired with healthy fats like olive oil and nuts, as well as high-quality proteins such as fish, eggs, and beans. By simply making different choices, you can stabilize blood sugar without having to go hungry.

Maintain a Healthy Weight

Maintaining a healthy weight is also very critical for controlling blood sugar. Especially for type 2 diabetes, obesity can be said to be one of the most significant risk factors. Being overweight makes the body's response to insulin poorer, making blood sugar more likely to spiral out of control. Conversely, if weight is gradually reduced even a little, there is a chance to make blood sugar more stable and reduce the risk of future complications worsening.

Avoid Smoking

Smoking worsens the body's metabolic state and increases the risk of developing diabetes by 30% to 40%. Not only that, if you already have diabetes, smoking can make the condition harder to control, further increasing the risk of complications such as cardiovascular disease, kidney damage, and even peripheral neuropathy.

Common Questions About Diabetes

What Complications Can Diabetes Cause?

If diabetes is not well-controlled over the long term and blood sugar remains high, it will gradually affect various organs throughout the body. For instance, the eyes may develop retinopathy, with a risk of blindness in severe cases; the heart and blood vessels will also be affected, increasing the probability of cardiovascular disease; and kidney function may gradually deteriorate, leading to kidney failure in the most serious cases. Additionally, peripheral nerve damage and poor blood circulation can cause numbness in the hands and feet, difficulty in wound healing, and even situations severe enough to require amputation.

Unexplained Abdominal Pain and Vomiting: Is It Gastritis or Worsening Diabetes?

If you have diabetes and suddenly experience unexplained abdominal pain, nausea, or vomiting, many people might think it's just gastroenteritis, but you need to be very careful. Sometimes these symptoms are combined with extreme thirst, frequent urination, general weakness, and even rapid breathing, which may not be a simple gastrointestinal problem but a warning sign of worsening diabetes, such as early diabetic ketoacidosis (DKA). This situation requires seeking medical attention as soon as possible to test blood glucose and ketones to prevent the situation from deteriorating rapidly.
