Drinking tea and smoking heavily has been linked to urinary incontinence in women, research suggests.
A study found smoking more than 20 cigarettes a day was linked to the complaint.
The common myth about urinary incontinence is that it only affects the elderly, but the condition affects one in 10 people.
Up to 25% of women and 5% of men aged 15 to 64 are affected.
Norwegian researchers surveyed almost 28,000 women aged over 20 in the Nord-Trøndelag area of the country between 1995 and 1997.
They wanted to see if smoking, obesity, physical activity and the drinking alcohol, coffee or tea were associated with urinary incontinence in women.Source BBC News
