In today's society, with an aging population and changing lifestyles, chronic diseases have become a major threat to human health. Chronic diseases, also known as chronic non-communicable diseases, include cardiovascular diseases, diabetes, chronic respiratory diseases, and cancer, and are characterized by long duration, complex causes, and insidious onset. However, although chronic diseases progress relatively slowly, their harm to human health should not be underestimated. Because the initial symptoms of these diseases are often not obvious, many people easily overlook subtle changes in their bodies, thus missing the optimal treatment opportunity.
Characteristics and Harms of Chronic Diseases
The characteristics of chronic diseases lie in their long duration, insidious onset, complex causes, and the interplay of multiple factors. Many chronic diseases do not have obvious symptoms in their early stages, making it difficult for patients to detect them in time and take effective measures. However, as the disease gradually progresses, chronic diseases can damage multiple systems in the body, seriously affecting the patient's quality of life and even endangering life.
How to Pay Attention to These Early Symptoms?
- Self-monitoring: Have regular health checkups and pay attention to subtle changes in your body.
- Balanced diet: Maintain a balanced intake of nutrients and reduce the intake of high-sugar and high-fat foods.
- Regular Exercise: At least 30 minutes of aerobic exercise daily helps improve the body's resistance.
- Mental Health: Maintain a good mental state, learn to manage stress, and avoid emotional fluctuations.
Common Chronic Diseases
Hypertension
Hypertension is often called a "silent killer" in its early stages because its symptoms are very insidious and difficult to detect. However, it may already be quietly damaging blood vessels and organs such as the heart, kidneys, and brain. Some patients may experience mild headaches in the early stages, especially upon waking in the morning. These headaches are usually dull or pressing, concentrated in the back of the head or forehead. Dizziness is another common early sign; sometimes, standing or suddenly getting up can cause lightheadedness, which is related to the impact of blood pressure fluctuations on blood supply to the brain.
Some people may experience palpitations or tinnitus. Palpitations manifest as a rapid or abnormal heartbeat, while tinnitus is a persistent buzzing sound. These symptoms reflect the stimulation of the sympathetic nervous system by blood pressure fluctuations. Some people may also experience neck stiffness or soreness, especially when stressed or fatigued, which may be related to muscle tension and vasoconstriction caused by elevated blood pressure. However, because these symptoms are mild and subtle, many people often mistake them for excessive stress or fatigue.
Because the symptoms of hypertension are diverse and easily overlooked, regular blood pressure monitoring is particularly important. Even if you feel no abnormalities, you should measure your blood pressure at least once a year, especially those with high-risk factors such as a family history of hypertension, obesity, or long-term smoking. Early detection of elevated blood pressure allows for intervention through dietary adjustments, exercise, and medication, preventing the condition from progressing further. Ignoring these early warning signs can lead to serious complications such as heart disease, stroke, or kidney failure.
Diabetes
Early symptoms of diabetes are often subtle and easily overlooked, but early identification and intervention are crucial for controlling blood sugar levels and delaying the onset of complications. The typical "three highs and one low" symptoms are early warning signs of diabetes: increased thirst, increased urination, increased appetite, and weight loss. Patients often experience abnormal thirst, frequent drinking, and significantly increased urination, especially at night. Despite increased appetite, the body cannot effectively utilize glucose, leading to increased breakdown of fat and muscle, resulting in abnormal weight loss.
In addition, early-stage diabetes patients may experience fatigue and weakness due to imbalanced blood sugar levels affecting energy metabolism, preventing cells from obtaining the necessary energy. Dry skin, itching, and slow wound healing are also common signs. These problems are related to high blood sugar damaging microvessels and weakening the immune system, reducing the skin's self-repair ability. Female patients are also prone to recurrent vaginal infections, while men may experience skin or urinary tract infections.
Another type of early symptom manifests in vision. Blurred vision or dry eyes may be related to elevated blood sugar affecting retinal and microvascular function. Some patients may even experience temporary vision changes when blood sugar levels fluctuate significantly, providing a clue for early medical attention.
Once the above symptoms appear, blood sugar should be tested promptly, and lifestyle interventions should be implemented according to the doctor's advice, such as adjusting diet, increasing exercise, and using medication to control blood sugar if necessary. Early detection and intervention can effectively reduce the risk of diabetic complications, such as retinopathy, kidney disease, and cardiovascular disease. Regular blood sugar checks, especially for those with a family history of diabetes, obesity, or high stress levels, are important measures to prevent diabetes from worsening.
Coronary Artery Disease (CAD)
Early symptoms of CAD often manifest as chest discomfort, but because the symptoms are mild, they are often mistaken for indigestion or ordinary fatigue. Patients may experience chest tightness, shortness of breath, or even chest pain during exercise, but these symptoms usually subside after rest. In addition, some people may experience unexplained pain in the upper limbs, neck, or jaw, which is a signal that ischemic blood flow is radiating to other parts of the body. Sometimes, early CAD is also accompanied by mood swings or insomnia, which may be related to insufficient blood supply to the heart.
Conclusion
Chronic diseases are not slow, and their harm should not be ignored. However, through early detection and management, we can effectively control the development of chronic diseases and reduce their impact on patients. Therefore, we urge the public to raise awareness and preventative measures against chronic diseases, actively participate in regular physical examinations and screenings, and promptly detect and address early signs of chronic diseases. At the same time, the government and all sectors of society should increase investment and support for chronic disease prevention and control, jointly building a chronic disease prevention and control system to safeguard the health of the people.
