Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.WHENEVER I cough or sneeze, I wet myself. This has been diagnosed as "stress incontinence", but I can't understand what this has to do with stress.
Stress incontinence has nothing to do with psychological stress. It is a term for the inability to prevent urine from leaking out of the bladder.
Urine leaks out when you cough or sneeze because the valve that closes off the bladder is faulty. Coughing, sneezing - even laughing - cause an increase in pressure on the bladder; when the outlet valve is weak, urine dribbles out.
Women often develop this symptom after childbirth. You can strengthen the valve by exercising the muscles in the pelvic floor that allow you to cut off the flow of urine in midstream. If this does not work, an operation may be necessary.
A WOMAN in my office has extremely bulgy eyes. Is this caused by a medical problem?"
She is probably suffering from an overactive thyroid gland. This gland is situated in the front of the neck, just below the larynx. When it produces too much of its hormone, thyroxine, it causes weight loss, sweating, tremor and bulging eyes.
An overactive thyroid is much more common in women than in men. Beta- blockers such as propranolol help some symptoms, and other drugs are used to control the overproduction of thyroxine, but the bulginess of the eyes can persist long after the level of thyroid hormone is back to normal. In severe cases, vision can be put at risk.
I HAVE heard of a nasal spray that can be used to treat bed-wetting. Can you explain how it works?
By the age of five, about 80 per cent of children are completely dry at night - but two in 10 still wet the bed. Most of them will become dry at night within the next two years. But this common problem is embarrassing and disruptive.
One new treatment is a nasal spray that reduces the amount of urine that the body produces overnight. This can have a dramatic effect on bed-wetting. It is called desmopressin, and it comes as tablets or a nasal spray. It is available only on prescription, and its use has to be carefully monitored.
CAN DRINKING cranberry juice prevent cystitis?
This popular remedy has been shown to reduce the incidence of cystitis and other urinary infections.
Some researchers believe it fights infection by making the urine more acidic; or that it makes it more difficult for bacteria to stick to the wall of the bladder.
