Chronic Disease: Identification, Prevention, and Management

Chronic illnesses are medical conditions that generally last one year or more, require ongoing medical attention, and can affect activities of daily living. In some regional contexts, such as Australia, a condition is considered chronic if it has lasted, or is expected to last, at least six months. Common examples include obesity, hypertension, diabetes, asthma, and heart disease.

Most chronic diseases are caused by a short list of modifiable risk factors. You can significantly reduce your risk through:

1. Physical Activity: Aim for 150 to 300 minutes of moderate-intensity aerobic activity per week. Activities like swimming, cycling, and running help reduce the risk of stroke, type-2 diabetes, and certain cancers.
2. Nutrition and Diet: A healthy eating plan emphasizes fruits, vegetables, and whole grains while remaining low in added sugars, sodium, and saturated fats.
3. Avoidance of Toxins: Quitting smoking or never starting is essential to lower the risk of lung disease, heart attacks and stroke. 
4. Weight Management: Maintaining a healthy Body Mass Index (BMI)—generally between 18.5 and 24.9—is a key preventive measure.
   

Screening refers to medical tests that are used to detect hidden diseases or risk factors in seemingly healthy individuals before symptoms appear, allowing treatment to begin when it is most effective. Common screenings include:

1. Blood Pressure: Identifying hypertension to prevent stroke and kidney failure.
2. Lipid Profiles: Checking cholesterol levels to manage cardiovascular risk.
3. Glucose Testing: Detecting prediabetes or type 2 diabetes.

With effect from 1 July 2026, Raffles Clinic at NTU has been appointed as Healthier SG clinic. For more information on booking of government sponsored health screening at the clinic, refer to Healthier SG enrolment with NTU Campus Clinic.

Your doctor may recommend more frequent screening based on specific risk factors:

1. Family History: Genetic predispositions to cancer, heart disease, or diabetes.
2. Age and Gender: Certain conditions, like osteoporosis or prostate issues, become more prevalent as you age.
3. Personal History: Previous health events or existing comorbidities (like obesity) often necessitate earlier or more frequent monitoring.

It is important to remember that screening is generally not a definitive diagnosis. A review with the doctor to better understand the results is recommended.

1. Screen Negative (Normal): This means you are currently at low risk for the condition, but it does not guarantee you will never develop it.
2. Screen Positive (Higher-Risk): This indicates a higher likelihood of the disease. In this case, you will be offered confirmatory diagnostic tests to ensure an accurate diagnosis.

Effective management requires a proactive, multidisciplinary approach.

1. Medication Adherence: Taking the right dose at the right time is essential for controlling symptoms and preventing complications.
2. Home Monitoring: Use tools to track your blood sugar or blood pressure and report changes to your healthcare team immediately.
3. Self-Management Education (SME): Participate in programs that teach skills to manage symptoms, reduce stress, and improve sleep.
4. Multidisciplinary Teams: Work closely with a team that may include your physician, pharmacist, dietician, and psychologist.

Based on general guidelines for average-risk individuals:

While most chronic diseases are lifelong and incurable, the primary goal of management is to ease the disease path rather than provide a cure. However, some chronic infectious diseases (like Hepatitis C) and certain types of cancer can be treated successfully if detected early. For conditions like type 2 diabetes, intensive lifestyle interventions can sometimes delay onset by many years or even forestall its emergence.

In structured management programs, such as Singapore's CDMP, vitamins and dietary supplements are generally not covered unless there is a medically documented deficiency. Specific supplements like Red Yeast Rice or Co-enzyme Q10 are often excluded from claimable treatments for lipid disorders due to a focus on evidence-based pharmacological therapies. Always consult your healthcare provider before starting supplements, as they are not a replacement for prescribed treatments.
