Digestive complaints such as constipation, diarrhoea, heartburn and bloating are very common and usually treatable with lifestyle measures and medicines you can buy without a prescription from a pharmacy.
Around 4 in 10 people have at least one digestive symptom at any one time, according to Dr Anton Emmanuel, consultant gastroenterologist at University College Hospital in London.
The most common are:
"Most digestive problems are to do with lifestyle, the foods we've eaten, or stress. Which means that taking steps to change your lifestyle can help, and often prevent, many of these problems," says Dr Emmanuel.
"There's a wide choice of pharmacy medicines for heartburn, indigestion and similar problems that are very good for short-term relief of symptoms," he adds.
Medicines that can upset your tummy
Certain medicines that your doctor may have prescribed for you for other health conditions can lead to side effects that may upset your tummy and cause indigestion, diarrhoea or constipation.
Talk to your GP if you rely on these medicines and are also prone to indigestion or ulcers. Paracetamol is a useful alternative.
Certain tranquillisers, painkillers, iron tablets and cough medicines can cause constipation and some people get diarrhoea while taking antibiotics or blood pressure medicine.
Always tell your doctor if your prescribed medicines are upsetting your tummy.
When to see a doctor
Digestive symptoms are usually harmless and often settle down by themselves, but sometimes they do not go away and can be a signal of serious illness.
