1 in 4 people suffer from heartburn!

A new study, published in this week's issue of The Lancet, Nicholas Talley, MD, and colleagues at the Mayo Clinic in Rochester, Minn. looked at the prevalence of heartburn reported in 31 studies on the topic.

The highlights of the article include:

-25% of people in Western countries report symptoms of heartburn at least once a month; 12% suffer from the burning and pain in the chest at least once a week.

-only 11% of those living in Eastern Asian countries report having heartburn at least once a month and 4% weekly.

-5% in the West report symptoms every day.

Although the exact cause of heartburn is unknown, genetic factors are thought to play a role. Obesity and lifestyle factors such as eating certain foods, drinking alcohol, and smoking increase the risk of developing heartburn.

  1. To expand on Happy Tummy's post, I will give
    you a little more information about what causes heartburn. To start, caffeine contains something called theobromine, which is found naturally in many caffeine bearing plants. Theobromine relaxes the LES muscle, and as stated by Robert M, the acids shoot up into the esophagus. Another top cause of heartburn is fried and fatty foods. Fatty foods have a tendency to slow down the digestion process, which leads to the food being kept in the stomach for a long time. This results in increased pressure to the stomach. This pressure build-up will weaken the LES allowing stomach acid to pass into the esophagus. A third cause, is tomatoes, tomato-based products, and alcohol also cause the LES to relax. These foods lead to an increase in the production of more stomach acid, which will add to stomach pressure.
