Tummy troubles

Diarrhoea

If it's acute, it could be food poisoning, anxiety or gastroenteritis. If it's chronic, it's likely to be IBS, which means your bowel doesn't function correctly.

What can you do? For acute diarrhoea, use rehydration salts (try Dioralyte, £3.55 for six sachets from pharmacies) to replace lost fluids, and a product such as Imodium (£6.90 for 18 capsules from pharmacies) to settle your tummy. For chronic diarrhoea, talk to your GP.

When to worry ‘Chronic diarrhoea needs to be investigated, as it can also be due to bowel inflammation (such as, Crohn's disease or ulcerative colitis) or poor absorption of food (caused by coeliac disease or a chronic pancreas disease),' says Alastair. ‘Take care if you're over 50 when it first occurs.'
