It’s a wider symptom of acid reflux – where stomach acid travels up toward the throat.
Signs of both heartburn and acid reflux usually get worse after eating or when lying down.
Eating certain foods this festive period could help to avoid the painful signs of heartburn, it’s been claimed.
One of the best ways to prevent heartburn pain is to eat more low-acid foods, said medical website WebMD.
Chicken and turkey are relatively low-acid, it said. It’s best to grill, bake or steam your poultry.
You should also avoid eating the skin, as it could trigger acid reflux, it added.
“You’ve heard about the foods that can make your heartburn worse, from coffee to chocolate to tomatoes,” said WebMD. “But what about foods that could make your heartburn better?
“When acid and other liquids in your stomach back up into your oesophagus, you get heartburn.
“The acid that’s already in your stomach isn’t the only problem, though.
“Prepare chicken and turkey grilled, broiled, baked, or steamed. Just remove the skin – and don’t fry it.
“Even ground beef and steak can be fine, as long as they’re lean.”
The best vegetables for preventing heartburn are green vegetables, said the medical website.
Broccoli, asparagus, green beans, celery and cauliflower are all particularly low in acid.
Potatoes should also form part of your Christmas dinner, as could all other types of root vegetable, bar onions.
Bread is also a good side dish for avoiding acid reflux. But, be sure to opt for wholegrain bread.
If you usually suffer from acid reflux, there are some ways to limit your risk this Christmas, said the NHS.
Eat smaller meals on a more regular basis, it said. If you’re overweight, losing weight could also help to prevent the condition.
You could also try to wear clothes that are more loose fitting, and stop smoking, if you’re a smoker.
Speak to a pharmacist for advice on the best over-the-counter medications available if your heartburn keeps coming back.
