Obesity is a Disaster Requiring Urgent Intervention in South Africa – Longevity LIVE – Longevity LIVE

800 million people around the world are affected by obesity. According to Riekie Smit, MD, South Africa has alarmingly high rates of adult obesity. More than half of the female population and over a quarter of the male population are obese. Up to 70% of the female population is either overweight or obese.

South Africa is also rated in the top 3 countries in Africa in terms of adult obesity rates, with no signs of this abating. Even worse, childhood obesity rates are continuing to rise. According to Diabetes South Africa, 20% of girls younger than 9 years are overweight. Alarmingly 13,5% of school-going children are overweight or obese, which is higher than the 10% global rate.

Obesity is defined as having a body mass index (BMI) of 30 or more. Your BMI is calculated with a simple formula of your weight (kg) divided by your height (m) squared. BMI calculators are also easily accessible online.

This should not be the only guideline used, as your waist circumference is another really important measure of your risk for health problems. A high-risk waistline is over 80cm for women or over 94cm for men, and this indicates an increased risk for high blood pressure, diabetes, cardiovascular diseases and other conditions.

Diabetes, which is one of the conditions associated with obesity, is now the largest killer of South African women according to Statistics SA research.

What we have seen is that having type 2 diabetes also increases your risk of severe illness from COVID-19. In fact, adults of any age withcertainunderlying medical conditionsare at increased risk for severe illness from the virus that causes COVID-19, including being overweight and obese.

The main reason for this is the comorbidities associated with obesity. I am often surprised at how many obese patients are not aware of the other medical conditions they already have.

Obesity, as well as its comorbid diseases, affects ones immunity and your bodys ability to recover from illnesses. Obesity is associated with a depressed immune system and chronic low-grade inflammation in your body.

In fact, researchers have established the likelihood that the presence of excess fat or adipose tissue could increase transmission of the virus between organs and could possibly increase viral load and drive disease severity.

Obesity is associated with reduced cardiac and respiratory function, kidney pathology and all these and the other comorbid conditions gives rise to the poor outcome that many obese patients have when infected with COVID-19.2 Worse yet, obese people generally seem to respond poorly to vaccinations and antiviral treatments.

Furthermore, obesity increases your risk for numerous other health conditions, many of which can be fatal. Overall, obesity is estimated to increase the risk of dying from heart conditions by four times. It also doubles your risk of cancer-related death.

For persons with severe obesity (BMI >40), life expectancy is reduced by as much as 20 years in men and 5 years in women.

Numerous scientific studies have revealed that most of the obesity related medical conditions improve significantly with a weight loss of as little as 5% to 10% of your body weight. This should really motivate anyone with health or weight problems. I advise people with weight issues to educate themselves and the people close to them about how weight issues affect health.

This includes understanding why maintaining a healthy weight is important.

If you are worried about your weight, speak to your doctor for advice about how to lose or manage your weight. Educate yourself, write down the steps. Have a goal, and then start following the steps. You will also need help and advice from those with experience. If you are struggling with obesity issues monitor your progress. If there is no progress, get help, rather than give up.
