Many health conditions develop silently, showing little or no symptoms until they become serious. Regular health checks with your GP can help catch these issues early, making them easier to manage and often preventing long-term complications. Preventive care is one of the most important reasons to visit your GP, no matter your age or current health. This article explains what a health check usually involves, how often you should have one, and why it plays such a crucial role in preventing chronic disease. What Is a Regular Health Check? A health check is a routine appointment with your GP to review your overall wellbeing. It usually involves: Medical history review: looking at family history, lifestyle, and past health concerns Physical examination: checking weight, blood pressure, heart rate and other vital signs Blood and urine tests: to measure cholesterol, blood sugar, kidney and liver function Screening questions: covering mental health, lifestyle habits, and cancer risk factors Immunisation review: ensuring your vaccinations are up to date Depending on your age, risk factors, and current health, your GP may also recommend additional tests such as ECGs, bone density scans or skin cancer checks. Why Regular Checks Matter for Chronic Disease Prevention Chronic diseases such as diabetes, heart disease, kidney disease and some cancers are leading causes of illness in Australia. The good news is that many can be prevented or managed effectively if detected early. Health checks allow your GP to: Identify early risk factors such as high blood pressure, elevated cholesterol or weight changes Detect silent conditions like type 2 diabetes, which often has no obvious symptoms in its early stages Support lifestyle changes before problems become serious Coordinate referrals to specialists when further assessment is needed By taking a proactive approach, you’re less likely to face complications later in life and more likely to stay active and well. How Often Should You Have a Health Check? Under 30 Years Most healthy adults under 30 may only need a full health check every two to three years. However, annual visits are recommended if you have risk factors such as smoking, obesity, or a family history of chronic illness. 30 to 50 Years At this age, annual health checks become more important. Regular blood pressure, cholesterol and diabetes screenings can help detect early warning signs. Over 50 Years From age 50 onwards, yearly health checks are strongly recommended. This age group benefits from additional cancer screenings, heart health checks, and bone density assessments. Tailoring Health Checks to Individual Risk Your GP doesn’t take a one-size-fits-all approach. Instead, checks are personalised based on: Family history of conditions like heart disease, diabetes or cancer Lifestyle factors such as diet, physical activity, alcohol use and smoking Previous test results or existing conditions Workplace or travel needs that may require specific assessments For example, if you have a family history of skin cancer, your GP may recommend more frequent skin cancer checks . If you’re managing a chronic illness already, your health check will focus on ongoing monitoring and adjustment of your treatment plan. What Happens if an Issue Is Detected? If your health check identifies an area of concern, your GP will discuss next steps with you. This may include: Ordering more detailed tests Recommending lifestyle changes Prescribing medications if needed Referring you to a specialist for further investigation At Tewantin Medical Centre , our GPs also provide coordinated support through chronic disease management and health assessments to help you stay on top of your health. Overcoming Barriers to Regular Health Checks It’s common for people to delay health checks because they feel well, are too busy, or worry about costs. However, skipping preventive care can lead to bigger problems later on. Feeling fine doesn’t always mean you’re healthy – many conditions develop silently. Short appointments can fit into your schedule and provide reassurance. Medicare subsidies apply to certain health assessments, especially for older adults and people with chronic conditions. Investing in preventive care now can save you stress, time, and money in the future. Why Choose a Noosa GP for Your Health Checks?

It’s normal to feel cold on a chilly day or after swimming in cold water. But if you’re always cold, especially when others around you feel comfortable, it might be time to look into what your body is trying to tell you. Persistent cold sensitivity can be a sign of an underlying health issue, such as low iron levels, thyroid problems or poor circulation. Understanding the potential causes can help you know when to seek medical advice. Understanding Your Body’s Temperature Regulation Your body maintains a steady core temperature through a process called thermoregulation. It involves multiple systems, your brain (particularly the hypothalamus), blood vessels, muscles and fat stores, all working together to keep you warm or cool as needed. When something disrupts this balance, you may feel colder than usual, even when the environment isn’t especially cold. When Feeling Cold Might Be Normal Not all cases of feeling cold are linked to a health issue . People with a slimmer build may have less insulation, while dehydration, lack of sleep, or age-related changes in metabolism and circulation can all affect how your body regulates temperature or simply being in a cold environment without proper clothing can all make you feel colder than others. However, if you’re still feeling unusually cold despite addressing these factors, it’s a good idea to consult your GP. Common Medical Reasons for Feeling Cold All the Time Certain medical conditions can affect how your body produces or retains heat. Recognising these potential causes can help you understand why you might feel cold all the time and when it’s time to consult your doctor. 1. Iron Deficiency (Anaemia) Iron helps produce haemoglobin, a protein in red blood cells that carries oxygen throughout your body. When you’re low in iron, your cells don’t receive enough oxygen to generate heat efficiently. Symptoms may include: Constant fatigue Pale skin Shortness of breath Dizziness Cold hands and feet Iron deficiency is especially common in menstruating women, vegetarians and people with chronic blood loss or poor absorption. 2. Hypothyroidism (Underactive Thyroid) The thyroid gland regulates metabolism, which influences how much heat your body produces. When your thyroid is underactive, everything slows down including your ability to generate warmth. Symptoms may include: Constant cold feeling Weight gain Dry skin Constipation Depression or sluggishness Hypothyroidism is commonly caused by autoimmune conditions like Hashimoto’s thyroiditis. 3. Poor Circulation Reduced blood flow means less warmth reaches your extremities. This is often noticeable in the hands and feet and may be due to: Raynaud’s phenomenon Peripheral artery disease Cardiovascular disease Diabetes-related vascular changes 4. Low Body Weight or Malnutrition When the body lacks sufficient fat or calories, it struggles to maintain warmth due to reduced insulation and energy reserves. This is often seen in people with eating disorders, chronic illnesses, cancer, or in older adults with poor appetite or limited access to nutritious food. 5. Hormonal Changes Hormones like oestrogen and progesterone affect body temperature. Women may notice increased cold sensitivity during certain times in their menstrual cycle or during menopause. 6. Diabetes and Blood Sugar Issues Blood sugar fluctuations can affect your circulation and nervous system, particularly in people with uncontrolled or long-standing diabetes. This can lead to cold extremities and impaired temperature perception. 7. Chronic Fatigue Syndrome or Fibromyalgia These conditions are associated with heightened sensitivity to cold, pain and fatigue. The exact cause isn’t fully understood but may involve nervous system dysregulation. 8. Medications That May Cause Cold Sensitivity Certain drugs can make you more sensitive to cold, including: Beta-blockers (for high blood pressure) Some antidepressants Certain chemotherapy agents Drugs affecting thyroid function If you suspect a medication is contributing, speak to your doctor before making any changes. 9. Other Less Common Medical Conditions These may include: Kidney disease Pituitary or adrenal gland disorders Chronic infections B12 deficiency While rare, these conditions may show up as cold intolerance alongside other systemic symptoms. When to See a GP About Feeling Cold All the Time You should book a GP appointment if your cold sensitivity is: Persistent and unexplained Accompanied by symptoms like fatigue, weight changes, or changes in mood Causing disruption to your daily life or sleep Affecting your ability to exercise or tolerate usual temperatures Early diagnosis and treatment can prevent complications, especially in cases of anaemia, thyroid dysfunction or circulatory problems. Tests Your Doctor May Recommend To understand why you’re feeling cold all the time, your GP may order blood tests to check iron levels, thyroid function, vitamin B12, and general health markers. Blood sugar and urine tests can help rule out diabetes or kidney issues. If circulation problems are suspected, you may need an ECG or imaging. In some cases, you might be referred to a specialist for further assessment. Managing Cold Sensitivity at Home While your GP works to identify the cause, a few simple steps may help you stay more comfortable: Dress in warm layers using thermal or wool fabrics. Use heated blankets or hot water bottles to maintain warmth, especially at night. Eat a balanced diet with plenty of iron, protein and healthy fats. Stay hydrated to support your body’s temperature regulation. Move regularly during the day to improve circulation. Track your symptoms , noting when you feel cold and any patterns that emerge. These steps won’t replace medical advice, but they can help you feel more at ease while you seek answers. Don’t Ignore Persistent Cold Sensations If you’re feeling cold all the time and unsure why, Tewantin Medical Centre is here to support you. Our GP doctors can assess your symptoms, arrange necessary tests, and help determine if conditions like low iron, thyroid dysfunction or circulation issues may be the cause. If your body is sending signals, don’t ignore them. Book a consultation with your GP to discuss your symptoms and get the support you need for your long-term health and wellbeing.
