ماذا يقول بولك عن صحتك

What colour was your urine last time you peed? Chances are, you've no idea. A recent استطلاع revealed that only 20% of men and 12% of women check the colour of their pee each time they go.

But monitoring your pee is such a good idea that Public Health England recently ran a 'Look before you flush' initiative, as part of their 'Be Clear on Cancer' campaign, to encourage people to take a glance at their urine output to make sure all is well. But what does the colour of our pee indicate? And when should we worry?

الجفاف

If you're worried about الجفاف, taking a look in the bowl after a pee is a far better indicator than monitoring your input.

"People are often advised to drink 6-8 cups of liquid a day," explains GP Dr Dawn Harper, TV medic and spokesperson for the campaign. "But who's to say how much that really is? In fact, your need will depend very much on the ambient temperature and your activity level. A great way to tell whether you're sufficiently hydrated is by looking at the colour of your urine. If it's not straw or champagne-coloured, you need to drink more; the darker the colour the more dehydrated you are."

دم في البول

It might not be as easy as you think to tell if there's blood in your urine. As well as a bright red, blood may appear pink or even brownish in colour.

"Blood can take on any form from pale pink - the colour of rosé wine - to pillar box red, right through to a cola shade of brown," explains Harper.

Whilst blood in the urine may be a sign of bladder أو سرطان الكلى, most of the time it's nothing serious. In fact, many things can cause your urine to appear this way.

"It could be a kidney stone, a sign of inflammation, infection or even just eating too much beetroot!" Harper reveals.

However, even if you cast your mind back to last night's salad and realise it was beetroot-heavy, it's important to see your doctor to have any potential blood in the urine investigated - even if it has only happened once - to make sure there's nothing else going on.

Other signs to look for

As well as noting the colour, there are other signs that may indicate a problem with your urine.

"Some people have a fishy smell to their urine a lot of the time," explains Harper. "This may be due to an enzyme deficiency which can be corrected through diet.

"But if the smell is pungent, or the urine is cloudy in appearance, this may be another sign of infection."

Making an appointment

If you think you may have blood in your urine, it's a good idea to get it checked out quickly.

Some surgeries are incredibly busy and it may seem to patients that they are unable to get an appointment when they need one. To get the care you need, it's crucial that you explain to the receptionist exactly why you want to see the doctor.

"Some people worry about disclosing their personal health information to a receptionist, and for this reason may not get the appointment they need," explains Harper. "It's important to remember that doctors' receptionists are bound by the same rules of confidentiality as doctors.

"They may ask personal questions, but this is to make sure you get the best passageway through surgeries. They can be your ally, rather than your enemy.

"Most surgeries will have time set aside for urgent appointments, and if you explain to the receptionist that you think you may have blood in your urine, it is likely you will be seen quickly."

At the doctor

Going to the doctor after noticing a reddish colour to your pee may feel nerve-wracking; however, much of the time it won't lead to any invasive testing.

"The first thing the doctor would do is to take a detailed history from you," explains Harper. "They will also want to do a urine test - so if possible take a sample with you in a clean container, or a sample pot collected from your surgery in readiness.

"Even if you can't see any trace of blood in it anymore, it could be picked up with a dip-test. Doctors can also use this test to look for infection and other problems."

ماذا يحدث بعد ذلك؟

If, after performing the tests and ruling out common causes, the doctor is still concerned, it's likely you would then be: "referred to a specialist for more intricate scanning, or to look directly into the urethra with a cystoscope (a thin tube with a camera/light on the end)," explains Harper.

What if it's cancer?

Nobody wants to hear the 'c' word. However, as with all cancers, the sooner bladder or سرطان الكلى is detected, the better the prognosis. So whilst addressing the issue may make you feel nervous, it's better to seek reassurance or the necessary treatment if you think you've passed blood in your pee.

It's not the nicest view in the world, but glancing in the bowl really could save your life.
