That is because your urine color, not only has a connection with your health but also it has a link with what you are eating and drinking.

Dark-yellow color urine is mostly because of dehydration.

When you are dehydrated, your kidneys will absorb water, making your urine more concentrated, giving your urine a dark yellow color. 

You can resolve this by rehydrating yourself by drinking plenty of water. And you will see that your urine is turning back to natural color.

Red-colored urine

Red-colored urine can occur due to several reasons. It can be because of something ate or drank recently. For example, tea, coke, coffee, or food such as beetroot can make your urine red in color.

Sometimes when you have kidney stones, it can also turn your urine red-colored.

Apart from these simple explanations, sometimes red-colored urine lasting for weeks to months can be a sign of something sinister because the same red-colored urine can be due to a tumor in your kidneys or bladder.

So if you are an elderly adult with a history of red-colored urine lasting for more than two or more weeks, you should see your family physician and get medical advice. He will decide whether to investigate further.

Transparent urine

If your urine is too transparent or colorless like water, that can mean several different things.

One reason may be that you have overhydrated yourself, and with time your urine will return to its neutral color.

However, if you are persistently thirsty and drinking too much water, this may be an early sign of diabetes mellitus.

If that is the case, then meet your doctor and take advice on whether you need to do a fasting blood sugar test or not.


Brown-colored urine can be due to any reason causing muscle damage, which can be normal after a vigorous exercise. 

However, if you see brown-colored urine regularly, it can be a sign of liver disease, and you may have to consult a doctor for further medical advice.

Foamy urine
