Take our true or false test to learn whether your habits are troubling your tummy.

QUESTIONS

1. Antacids don't prevent heartburn

2. Stress is the most common cause of ulcers

3. A chronic cough can be a symptom of digestive problems

4. Constipation is the most common gastrointestinal complaint in the United States

5. Peppermint eases a stomachache

ANSWERS

1. True

The painful burning sensation in your chest occurs when stomach acid flows up into your esophagus - also called reflux.

Antacids neutralise this acid, but they can't stop its production.

To keep the burn at bay, make these easy lifestyle changes.

Eat at least three hours before bedtime, consume five smaller meals a day instead of three larger ones, and steer clear of trigger foods such as citrus and caffeine.

Over-the-counter or prescription drugs known as H2 blockers, which decrease production of stomach acid, may also prevent flare-ups.

2. False

Stress, alcohol, and spicy foods were all once blamed, but researchers now know that Helicobacter pylori bacteria cause most ulcers.

Infection with H. pylori, believed to reach the stomach via contaminated food or water or mouth-to-mouth contact such as kissing, is common in the United States - about half of those over age 60 have it.

Most people who harbour the microorganism, which weakens the protective lining of the stomach, don't develop an ulcer.

For the unlucky one in six who does, the condition is treated with antibiotics.

3. True

Gastroesophageal reflux, also commonly called heartburn, can produce a chronic cough and shortness of breath.

It can even mimic asthma. If the reflux happens two or more days a week for three months, see your doctor.

It may be a symptom of GERD, a more serious form of gastroesophageal reflux that can cause severe complications if left untreated.

4. True

Americans spend US$725 million on OTC laxatives annually to keep their bowels moving smoothly.

You shouldn't assume, however, that you're constipated if you don't have a daily bowel movement - normal may be three times a day or three times a week, depending on the person.

True signs of constipation include having hard, dry stools that are difficult to pass without straining, and feeling like you still need to have a bowel movement even after you've had one.

To stay regular, get enough fibre (at least 25 grams if you eat 1600 calories a day), take in plenty of water and fluid-rich produce, and exercise for 30 minutes most days of the week.

5. True

The herb is a digestive wonder. It calms the muscles of the stomach and improves the flow of bile, which the body uses to digest fats.

When you need the power of peppermint, it's best to opt for tea rather than gum.

Most people swallow more air than usual when they chew gum, which can lead to stomachaches and gas.

One caveat. Frequent heartburn sufferers should avoid peppermint because it can relax the muscle between the stomach and the esophagus, allowing acid to flow back up.
