A medical expert has revealed the six common habits that sabotage our bladder health, leading to incontinence or even deadly cancer. It is easy to overlook our bladders until they start causing trouble. The small, balloon-like organ in the lower urinary tract quietly stores and releases urine, helping the body eliminate waste and maintain fluid balance.
But Dipa Kamdar, senior lecturer in pharmacy practice at London’s Kingston University, has warned that just like your heart or lungs, your bladder needs care. Neglect it and you risk discomfort, urinary tract infections and, in some cases, serious conditions such as incontinence (the involuntary leakage of urine) or even cancer.
Certain foods and drinks – including fizzy drinks, spicy meals, citrus fruits and artificial sweeteners – can irritate the bladder and worsen symptoms for those already prone to problems.
Aim for a fibre-rich diet with plenty of whole grains, fruit and vegetables to protect both digestive and bladder health.
Bladder health is shaped by everyday choices. Staying well-hydrated, avoiding irritants, practising good hygiene and listening to your body can all help prevent long-term problems.
If you notice persistent changes such as frequent urination, difficulty emptying the bladder, pain or burning when you pee, cloudy or smelly urine, or any sign of blood, see a healthcare professional. Your bladder will thank you.
The good news: many bladder problems are preventable and linked to everyday habits – so writing in The Conversation, Kamdar reveals the six common habits that can sabotage bladder health.
1. Holding in urine too long:
“Delaying a bathroom visit allows urine to build up and stretches the bladder muscles. Over time this can weaken their ability to contract and empty the bladder completely, leading to urinary retention.
“Research shows that holding urine gives bacteria more time to multiply, raising the risk of urinary tract infections (UTIs).
“Experts recommend emptying your bladder every three to four hours. In severe cases, chronic retention can even damage the kidneys.
“When you do go, relax – women in particular should sit fully on the toilet seat rather than hovering, so the pelvic muscles can release. Take your time and consider double voiding: after you finish, wait 10–20 seconds and try again to ensure the bladder is fully emptied.”
2. Not drinking enough water:
“Dehydration makes urine more concentrated, which irritates the bladder lining and increases infection risk. Aim to drink six-to-eight glasses of water (about 1.5 to 2 litres) a day, more if you’re very active or in hot weather. If you have kidney or liver disease, check with your doctor first.
“Too little fluid can also lead to constipation. Hard stools press on the bladder and pelvic floor, making bladder control harder.”
3. Too much caffeine and alcohol:
“Caffeine and alcohol can irritate the bladder and act as mild diuretics, increasing urine production. A study found that people consuming over 450mg of caffeine per day – roughly four cups of coffee – were more likely to experience incontinence than those drinking less than 150mg.
“Another study showed men who drank six-to-ten alcoholic drinks per week were more likely to develop lower urinary tract symptoms than non-drinkers.
“Heavy alcohol use may also increase bladder cancer risk, although the evidence is mixed. Cutting back can ease bladder symptoms and reduce long-term risk.”
4. Smoking:
“Smoking is a major cause of bladder cancer, responsible for about half of all cases. Smokers are up to four times more likely to develop the disease than non-smokers, especially if they started young or smoked heavily for years – cigars and pipes included.
“Tobacco chemicals enter the bloodstream, are filtered by the kidneys and stored in urine. When urine sits in the bladder, these carcinogens, including arylamines, can damage the bladder lining.”
5. Poor bathroom hygiene:
“Improper hygiene can introduce bacteria into the urinary tract. Wiping from back to front, using harsh soaps or neglecting hand-washing can all upset the body’s natural microbiome and increase UTI risk.
“Sexual activity can also transfer bacteria from the bowel or vaginal area to the urinary tract. Both men and women can reduce their infection risk by urinating soon after sex.”
6. Poor diet and lack of exercise:
“What you eat and how active you are affects your bladder more than you might expect. Excess weight puts pressure on the bladder and increases the likelihood of leakage.
“Regular exercise helps maintain a healthy weight and prevents constipation, which otherwise presses on the bladder.”
