You should try and avoid being constipated as this can bring on other symptoms and problems. For example, when the bowel does not empty properly it will swell up and push down onto the bladder and could cause urinary problems.
You can avoid constipation by following a healthy diet, which can also help some bladder problems. A good diet will not only benefit your bladder but also your health in general. Try and eat a balanced diet that is not too high in fat and includes plenty of fibre. Aim for at least five portions of fruit and vegetables a day. Choose wholegrain varieties of bread, pasta and rice, rather than white versions.
Being overweight can also make your bladder problems worse. Extra weight may put pressure on the pelvic floor muscles which can become weak.
