Acid reflux on the rise

Cases of acid reflux are increasing and experts say obesity is to blame.

Researchers studied over 30,000 people and found the prevalence of acid reflux has risen almost 50% in ten years.

They say the number of people who are obese is the main factor behind the spike.

They also found an increase in a rare type of esophageal cancer linked to acid reflux.

Men and women of all ages saw a spike, but the most severe symptoms were among people who were middle-age.
