Six health checks that could help prevent serious illness and save your life

Routine health screenings are crucial in preventing serious illnesses and detecting conditions in their early stages. In South Africa, where chronic diseases are a growing concern, regular checks can help identify issues that may otherwise go unnoticed for years. High blood pressure, often referred to as the "silent killer," affects over one-third of adults and typically shows no symptoms until significant damage has occurred.

Early detection of high blood pressure through simple blood pressure checks can prevent it from contributing to heart attacks, strokes, or kidney disease. As people age and gain weight, cholesterol and blood glucose screening should become a priority. The South African Heart Association suggests more frequent checks for individuals with risk factors. When detected early, slightly elevated cholesterol and glucose levels can often be managed through diet and lifestyle changes.

Cancer screening becomes increasingly important from the age of 45. Colorectal cancer screening is typically recommended at this age, or earlier for those with a family history of colon cancer or polyps. Women should undergo regular mammograms, and men over 50 (or 40 with a family history) should consider regular prostate screenings. Although these screenings may be delayed, early detection can significantly improve treatment outcomes.

From the age of 50, bone density screening can help identify the risk of osteoporosis. Women are more vulnerable due to declining estrogen levels after menopause, while men can also develop osteoporosis. A bone density scan is a straightforward test that can reveal bone loss before it becomes a significant issue.

Eye tests, recommended every one to two years, serve a dual purpose. They not only monitor vision but can also detect early signs of diabetes, providing an early warning even before the condition affects eyesight. For those with no apparent vision problems, regular eye examinations can still be beneficial.

Depending on age and healthcare plans, several health checks can be performed simultaneously, making screening more convenient and cost-effective. Medical aid members may be able to access some of these checks as part of their benefits. For instance, Fedhealth offers an annual wellness screening through its Health Risk Assessment, which includes blood pressure, BMI, waist-to-hip ratio, cholesterol, and glucose testing.

The simplicity of these health checks is their strength. Identifying elevated cholesterol early allows for lifestyle changes before more serious intervention is needed. Early-stage cancer is generally more treatable than cancer discovered later. Regular health checks also establish a personal health baseline, making it easier to identify changes over time.

In addition to these screenings, dental examinations and skin checks are essential components of a regular health routine. Oral health is linked to conditions such as heart disease, while regular skin checks are particularly important in South Africa's sunny climate. Ultimately, the most important health checks are often the simplest tests that can identify issues early enough to change their course.
