Khaberni - Despite the availability of modern technologies for tracking health indicators, simple blood testing remains the fundamental pillar of a proactive health system.
British newspapers "Daily Mail" and "The Telegraph" recommend regular testing for those who exercise, especially those over forty. As this age is reached, the body begins to deteriorate, and blood tests are an effective way to monitor internal changes.
1. Cholesterol Test:
Many are aware of the presence of "good" (HDL) and "bad" (LDL) cholesterol. Cholesterol is generally misunderstood, but it is necessary for repairing blood vessels. The balance between the good cholesterol produced by the liver and small intestine, and the bad cholesterol produced by the liver and potentially entering the body through animal fats, is crucial. An even distribution is optimal, with the possibility that the doctor may recommend specific levels. The UK's National Health Service (NHS) recommends maintaining HDL at 1/1.2 or higher, and LDL under 3. An imbalance indicates problems; LDL accumulation may lead to arteriosclerosis and cardiac blockages. After forty, controlling cholesterol becomes necessary as the body's ability to naturally eliminate LDL decreases, increasing the risk of heart attacks. Preventative measures include aerobic and strength exercises, eating soluble fiber (like oats, beans, and apples), and unsaturated fats (like nuts and oily fish).
2. Thyroid Function Test:
Although small, the thyroid gland plays a vital role in regulating metabolism, heart rate, and body temperature through the production of the hormones thyroxine (T4) and triiodothyronine (T3). An imbalance in these hormones can affect cholesterol levels and cause weight gain and fatigue. Thyroid function is often overlooked, but it could be a principal cause for low energy and unexplained weight gain. About 10% of people suffer from hypothyroidism, and the percentage increases among women over sixty to 12-20%. Working with a nutritionist to adjust lifestyle (such as diet and sleep schedules) can help manage symptoms.
3. Testosterone Hormone Test:
Men understand the importance of testosterone for healthy aging, and it is equally important for women, especially after the age of forty. Thyroid issues and aging can cause a sharp decline in testosterone levels. For men, it starts declining between the ages of 35 and 40 by about 1% annually, while for women, it starts around thirty. A drop in testosterone can lead to psychological problems and fatigue. Knowing the levels is essential, as with appropriate support, they can be raised to improve heart health, prevent weight gain, and enhance happiness.
4. Vitamin D Levels Test:
About 85% of the population in some countries suffer from vitamin D deficiency, necessitating dietary supplements or adjustments. Vitamin D levels drop after forty, as the skin's ability to produce it from sunlight decreases. By age eighty, the body’s ability to convert it drops by 50% compared to age twenty. Vitamin D supplements are available and inexpensive. Testing is advised for those suffering from bone pain or fatigue. It is recommended to take a daily supplement with a dose of 3000-5000 international units, along with vitamin K2 to ensure optimal absorption.
5. Kidney Function Test:
The kidneys play a role in waste removal, red blood cell production, and maintaining the balance of water, salts, and minerals, and regulating blood pressure. A disruption in this balance affects the functions of nerves, muscles, and tissues. A blood creatinine test measures the efficiency of the kidneys in removing waste and fluids. Elevated creatinine levels may indicate chronic kidney disease. Often, symptoms do not appear until nearing kidney failure, where treatment might be too late.
6. Blood Sugar Levels Test:
High blood sugar levels are an increasing risk factor for diseases, with a 6% increase in people suffering from health issues as a result. Understanding normal sugar levels is vital for preventing and managing diabetes, and requires regular testing of glycated hemoglobin (HbA1c). This test measures the amount of glucose linked to red blood cells. A high HbA1c reading indicates high blood sugar levels and increased risk of complications. A slight and temporary increase may not be dangerous, but prolonged elevation causes serious problems, including nerve damage, vision issues, and diabetic ketoacidosis. A balanced diet, healthy weight, and regular exercise help lower blood sugar levels.
7. Blood Pressure Test:
Although not a blood test, blood pressure remains a crucial indicator of health, reflecting diet quality, physical activity level, and stress. Blood pressure rises with age and arteriosclerosis, increasing the risk of heart attacks. High blood pressure can be managed by reducing salt intake and increasing cardiovascular exercises. The old standard rate (140/90) is still associated with an increased risk of stroke and arteriosclerosis. People over forty are advised to aim for a measurement of 115/75 to reduce the risk of heart attacks.
