New research is a real eye-opener

Most Scots are well aware that obesity can lead to the development of a whole host of issues such as heart disease, stroke and kidney problems. Now new research has shown overweight young adults could also be damaging their eyesight.

The link is not immediately clear, but it appears high pressure within the brain causes the problem.

In the most extreme cases patients have even developed irreversible sight loss.

One might fondly imagine that the findings would result in many people already classed as obese being encouraged to shed some pounds.

Sadly, the number of scare stories already out there – not to mention the enormous burden being placed on the NHS – has not been enough to convince some of the benefits of healthy eating and regular exercise.

It all leaves one wondering just what it will take to make people change their habits.

As with excessive drinking and smoking, one could hardly say people are not well warned of the potential dangers of over-indulging.

In keeping with many health issues, the primary treatment is to lead a healthy lifestyle and work towards an appropriate BMI.

The new research is certainly interesting and worthwhile – whether or not it encourages people to change their ways remains to be seen.
