Obesity: It’s a Disease, Not a Choice –
A Message from Dr. Whitney Mentor
For many years, South Africa has viewed obesity through a narrow lens—often dismissed as a lack of willpower or a “lifestyle choice.” But as we look at the health of our nation in 2026, the medical community is shifting the narrative.
One in three South African adults is currently living with obesity. It is no longer just a “weight issue”; it is a complex, chronic disease that requires professional medical management.
Why We Must Classify Obesity as a Disease
In South Africa, clinical guidelines now recognize obesity as a chronic disease. This is a vital distinction because it removes the “blame” from the patient and places the focus on biology.
Research shows that up to 70% of a person’s weight is determined by genetics. While diet and exercise are fundamental pillars of health, they are often not enough to combat the hormonal and neurological processes that cause the body to “defend” a higher weight. By treating obesity as a treatable medical condition, we open the door to evidence-based treatments—ranging from medical nutrition therapy and psychological support to game-changing medications (like GLP-1 agonists) and surgical options.
The Domino Effect: Medical Issues Caused by Obesity
Obesity acts as a gateway to dozens of non-communicable diseases (NCDs). When we carry excess adipose tissue (body fat), it isn’t just “stored energy”; it is metabolically active tissue that sends signals to your organs, often leading to:
-
Cardiovascular Disease: The heart has to work significantly harder to pump blood, leading to hypertension (high blood pressure), heart failure, and an increased risk of stroke.
-
Type 2 Diabetes: Excess fat leads to insulin resistance, making it the primary driver of the diabetes epidemic in South Africa.
-
Joint and Bone Stress: Conditions like osteoarthritis are common as the skeletal system struggles to support the additional weight, particularly in the knees and hips.
-
Sleep Apnoea: Weight around the neck can obstruct breathing during sleep, leading to chronic fatigue and heart strain.
-
Specific Cancers: Obesity is strongly linked to an increased risk of breast, colorectal, and kidney cancers.
-
Mental Health Struggles: The societal stigma associated with weight often leads to higher rates of depression and anxiety.
Take the First Step with Dr. Whitney Mentor
The good news? Obesity is treatable. Even a modest weight loss of 5% to 10% can significantly reverse early heart damage, lower blood pressure, and improve blood sugar levels.
You don’t have to do this alone. Dr. Whitney Mentor specializes in helping South Africans navigate the complexities of weight management with a compassionate, science-backed approach. At our practice, we don’t just look at the scale; we look at the person. We focus on metabolic health, sustainable nutrition, and medical interventions that work with your biology, not against it.
