What You Urine Says About Your Health

What You Urine Says About Your Health

Have you ever wondered why your urine is a dark yellow sometimes? Wondering what’s causing it and whether you should be worried? Want to know what to do and how to stop it

Your urine can give a lot of clues to your health and what is going on inside your body. It’s easy to forget that urinating is a way your body gets rid of the things it doesn’t need and ‘flushes’ out your system of things that shouldn’t be there. Just as you would check your temperature for a fever, checking your urine can give you a better understanding of why you feel a little bit ‘off’.

To look for changes, you must of course know what is ‘normal for you.’ Everybody’s ‘normal’ is different so for you having a light-yellow urine when you are fully hydrated maybe normal but for someone else a straw-like yellow urine maybe ‘normal’. So, firstly make sure you know your urine looks like when you’re hydrated, that way you can work out if something is wrong or abnormal

Try checking your urine when you get up in the morning. Here, you would have most likely had 8-12 hours of not drinking anything, so you’ll be able to see what your urine looks like when you’re not hydrated. Then go back and check your urine at around lunch time, once you had consumed more liquids and are slightly more hydrated. If you can then check again before you head to sleep, when you should be fully hydrated, you’ll soon learn common occurrences and your ‘normal’ color. This will make noticing differences a lot easier for you

You may also want to try tracking your urine color. This may sound a bit strange, but if you begin to notice any changes to your urine and you’re not sure what could be causing them, keeping a diary may help. This will also be really helpful for your doctor if you have to pay them a little visit with your concerns, as you’ll be able to give them a lot more detail if you have written it all down somewhere.

So, if you want to know more about what can affect your urine color and what it might mean, we’ve put together a list of reasons that may be causing your urine to be dark yellow and tips on how to stop it and when to seek medical advice.

Reasons why your urine is dark yellow:

There are a number of reasons that could be causing your urine to be dark yellow, some of which are more serious than others. Many common causes for dark urine can be fixed at home quite easily, though others you may need to seek medical attention.

Most common causes

  • Dehydration
  • Foods

Dehydration is one of the most common cause of dark yellow urine. It is recommended that you drink at least 8 glasses of water a day (1.5-2 liters) to stay hydrated, though this can vary person to person. Around 60% of your body weight is water and staying hydrated is important when it comes to your body functioning properly including;

  • Getting rid of wastes
  • Keeping body temperature balanced,
  • Protecting sensitive tissues
  • Lubricating and cushioning joints.

If you are dehydrated, this could be what is causing your urine to turn dark yellow due to it being over-concentrated with waste. As well as being dark yellow, you may notice your urine has a stronger odor. You may also be suffering from other symptoms if you are dehydrated, so look out for those too, if you want to be sure

Other symptoms:

When you should increase water intake to prevent dehydration:

Some days you may need less/more water to stay hydrated, depending on what you are doing, where you are and how you feel health wise. Below is a list of situations which could mean you need to increase you water intake in order to prevent becoming dehydrated:

Therefore, avoiding dehydration is really important. If you suffer from diabetes and your doctor has put you on fluid restriction due to kidney, heart or lung disease, make sure you speak to your doctor about the amount of fluids you should be consuming to stay hydrated.

People suffering from vomiting and diarrhea:

If you are suffering from a sickness and diarrhea, food poisoning or something else causing vomiting and diarrhea, you must make sure you are replacing the fluids, sugar, salt and minerals you are losing. If this does not happen, then there is risk of becoming dehydrated. If you are able to, speak to your pharmacists about oral rehydration sachets which will boosts all the elements you need to stay hydrated. Also make sure you sip water slowly, this will again help keep hydrated throughout the sickness.

People suffering from heat stroke:

It’s easy to get carried away if you’re on holiday or just enjoy soaking up the hot weather.

If you are by a pool, simply taking a quick dip to cool down your body will help prevent you getting too hot, even if it’s dipping your legs whilst being sat on the edge, wearing a hat and sunglasses.

People who have drank too much alcohol:

Though drinking alcohol can be fun and delicious, drinking responsibly is really important. If you do not drink with care, dehydration could occur. So, when you do drink alcohol avoid drinking over the recommended alcohol intake (no more than 14 units per week) which should be spread over a number of days rather than consumed in one go

The best way to avoid dehydration whilst drinking, is by making sure you drink enough water at the same time. By drinking water before you consume alcohol and alternating a glass of water and a glass of the alcoholic beverage of your choice will help. Having a glass of water before bed will also help prevent dehydration. You may find the day after drinking alcohol you need to consume more water than usual to prevent headaches and/or dizziness. Make sure you carry around a bottle of water with you so you can have some whenever you feel you need it.

Ways to make sure you are drinking enough water:

If you think you are dehydrated, then you should drink more water. The next time you go to the toilet, check to see what color your urine is. If it has become more of a pale yellow, you’ll be able to tell that dehydration was the cause of dark urine. Once you are no longer dehydrated you should notice your urine is almost clear and you may need to go more often than usual.
Dehydration can become very serious and can cause a number of health problems. To avoid dehydration in the future, make sure you drink more water throughout the day, trying to hit the recommended amount as much as possible, this way your urine should be a paler yellow and you should be relieved of any other symptoms of dehydration
