Nov. 11, 2004 -- A late night meal of pepperoni pizza paired with an amusing pinot noir may sound romantic to some, but for people with acid reflux disease it is a declaration of war -- a call for heartburn.

Most heartburn sufferers know the foods and situations that trigger their painful symptoms -- the burning or pressure sensation behind the breast bone, or sour taste of acid in the back of their throat. Yet much less is known about the lifestyle factors that cause the condition.

Researchers in Sweden recently set out to identify these lifestyle factors, and they came to some surprising conclusions. While smoking, as expected, strongly increased the risk for developing acid reflux disease, drinking alcohol had little impact.

The study also showed that coffee consumption, which commonly triggers symptoms, actually appeared to protect people from developing the disease. Lifestyle modification techniques are frequently recommended to control heart burn. Avoiding foods and beverages that contribute to heartburn such as chocolate, coffee, greasy or spicy foods, tomato products, and alcoholic beverages are typically recommended.

"We know that drinking alcohol causes symptoms to occur in people who already have acid reflux disease, so we were quite surprised to find that long-term use did not increase the risk of developing it," researcher Magnus Nilsson, MD, of Stockholm's Karolinska Hospital, tells WebMD.

He added that the protective effects of coffee were a weaker association and may not truly reflect a protective association.

Smoking and Salt Increase Heartburn Risk

Roughly one in five people suffer from heartburn or acid reflux, known medically as gastroesophageal reflux disease or GERD. While genetic predisposition, obesity, smoking, and alcohol consumption have all been implicated in the development of the condition, GERD expert Philip Jaffe, MD, says causality has been hard to pin down.

"We are talking about something that affects roughly 25% of the world's population," he says. "It is hard to isolate individual risk factors for something that is so common."

Nilsson and colleagues based their findings on two major public health surveys conducted in Norway in the 1980s and 1990s. Just more than 3,100 people who complained of having heartburn and 40,000 people without reflux symptoms answered questions about lifestyle factors including diet, exercise, alcohol consumption, and tobacco use. The average ages of those with and without acid reflux disease were 52 and 48, respectively.
