Bright Yellow Urine Overview

Normal urine color usually range from pale yellow to deep amber because of the result of pigments referred to as urochrome and depending on the concentration level of the urine. Pigments and some compounds found in the foods that we eat and medications can result in a change of urine color. Just have a study of the foods you recently ate to confirm if they have a hand in the color of your urine. Most of the drugs we acquire over the counter and those prescribed by health care providers produce different urine tones, such as red, greenish blue and yellow color.

A strange color in the urine can signify presence of disease in the body. For example, if you produce a deep red to brown urine you may be suffering from a condition known as porphyria, which is rare, inherited condition of red blood cells.

  • Symptoms to look at

The normal color of your urine will vary according to the amount of water you drink. Increased fluid intake dilute the yellow pigment of the urine, and therefore, the more you drink, the clearer your urine looks. If you drink less fluid, your urine will become more concentrated and therefore the color becomes darker in color. In case of serious dehydration, this will result in urine that is amber in color.

However, urine can change in colors that are far beyond normal, such as blue, red, green, dark brown and even cloudy white.

Bright Yellow Urine Causes

Apart from the amount of fluids we drink, the color of the urine can be determined by other several factors we are going to discuss on this post. Bright yellow urine is primarily caused by the amount of water have taken.

More water makes the urine to become light and even appear to be clear. Little water in the body on the other hand will make your urine to be darker. What are the other factors that determine the color of the urine? There are many other factors that affect the color of the urine that one produce. This may include the following:

  1. Vitamin and mineral content in your diet

How can this be an effect? Most of the natural foods that we eat such as the berries and beets, and some foods that have been heavily processed may contain increased amounts of food dye. The dye may interact with some pigments to form a different color in the urine that is far much different.

Some vitamins B are also known to result in urine that has a yellow-green color. If you usually take supplements your urine color may become bright. Also, meal replacement shakes which usually contain some vitamins B may result in the same effect.

Some other food substances such as excess beta carotene or vitamins C may result in dark yellow or orange urine. Beta carotene is usually found in yellow and orange foods, and when absorbed in the body is converted to vitamin A. some of these foods may include carrots and sweet potatoes.

  1. Exercise

During working out, there is a lot of dehydration involved since more water is lost through sweat and therefore less is left to be urinated. This will make the urine to be more concentrated and in this case it will change its color to darker.

Working out that is done without increased drinking of water results in a serious condition that cause muscle breakdown. That is why if you worked out without serious hydration you may develop muscle pain with tea-colored urine. Therefore, you know what to do while you heat the gym.

  1. Medications

Prescribed medications and over the counter drugs may also have a hand in your bright yellow urine, or a more vivid color. For example, antibiotics, laxatives and some of the chemotherapy medications used to treat cancer are said to cause a great change in color of urine.

An antibiotic drug such as phenazopyridine that is used to treat urinary tract infection has a side effect which is orange-colored urine. The type of color your urine contains may depend on the type of drug you took, and therefore not all drugs will produce same color.

  1. Diseases

A change in the color of the urine may be a sign of an underlying medical condition in the body. There is several numbers of diseases that affect the normal color of the urine produced. These may include conditions such as liver problems, kidney issues and even bladder infections.

For example, if you produce cloudy urine that contains a foul smell, you may be suffering from either kidney or bladder infections. However, in this case, you may have other symptoms accompanied by the change in color of urine such as painful urination, fever, vomiting, head ache, or abdominal pain.

  1. Pregnancy

Pregnancy is being connected to the color change of urine by many women although research is still being done on this issue. In most cases women may connect bright yellow urine as one of the early signs of pregnancy. Even in some hospitals the doctor may have a look at the color of the urine before going ahead to test it.

While at home don’t just only depend on the color of the urine as the may sign of pregnancy. Find out if there are some other symptoms and if possible let your medical provider contact a real test to come up with correct results on this matter.

Bright Yellow Urine no Vitamins

In case you happened to take a daily multivitamin you may have realized that your urine changed the color to bright yellowish color. Vitamins and some asparagus have been known to have an effect on the urine color. Your urine may respond to color change either by turning to a bright, in some cases neon, yellow due to excess riboflavin.

Also known as vitamin B2, riboflavin is a common content that is found in almost all multi-vitamins. The component was first discovered in the year 1872 by a chemist known as Alexander Winter Blyth who noticed a yellow- green pigment in milk.

In the late 1870s it was then reported as lacto-chrome and lacto-flavin. It took a long time up to 1930, when the component that produce a yellow pigment was featured as riboflavin. (The “Flavin” part originate from a Latin word flavus meaning “yellow” or “blonde”)

  • Why riboflavin in vitamins give a yellow color

Almost all things that have color have some relations to light absorption. Riboflavin absorbs light strongly in high ranges. When this falls out of the light then we will see with our eyes, it is also riboflavin’s ability to absorb light at 450nm that give it the distinctive yellowish color.

  • Why riboflavin turn pee yellow

Studies have revealed that about 50% of all excess riboflavin is excreted through urine. Moreover, the maximum amount of the pigments that may be absorbed in a single dose is around 27mg, with half of it being absorbed in the first one and quarter hours. Therefore if an adult take enough vitamin, this content can be retained and therefore urine will have a nice yellow color.

Therefore, if your vitamin intake is poor, or you have no vitamin, this means that you do not have enough of this pigment in your body and therefore you will produce bright yellow urine. If you produce this type of urine color, have a look at your recent diet and if you realize you have not been doing much of vitamin intake, have your diet to blame for this change.

Bright Yellow urine Pregnancy Sign

There are some evidences that suggest that pregnancy has a hand in the color of the urine. Some sources reveal that early signs of pregnancy include producing bright yellow urine. However, there are no studies that have been done to support this claim.

For this case if you realized a change in your urine color and decided to refer it as a [pregnancy symptom, you may have to conduct other tests to ascertain that.

There are some medical offices that the doctor may ask for the color of the urine that you produce in relation to your pregnancy claim. However, in most cases a doctor may carry out other tests like urine test to make sure it is really pregnancy that is causing the bright yellow urine.

Dark Yellow urine Causes

Urinary Tract Infection (UTI)

Urinary tract infection is a very common disease that causes the change in color of the urine. It is the second and most common infection in the body. You can understand better how the urinary tract infection affects your body by studying this infection called urinary tract as discussed here.

The urinary tract infection

The urinary tract of the human being includes many parts of the body. These are your kidneys and bladder. The kidneys play a vital role to remove water and waste from the blood in your body. Water and waste are the contents that combine to form your urine. After the urine has been formed, it travels from the kidneys through ureters which are two small tubes.

This urine is then stored in the bladder where it is held in place by your sphincter muscle to prevent it from running out through the urethra when it is not the right time. When your sphincter muscle relaxes, the urine travels out of your body through the urethra. Having read the urinary tract composition above, you can see there are a few areas that are affected by the process of creating urine

Bacteria are the cause of the urinary tract infection. Normally the urine created in your body is basically sterile and bacteria free. However, the bacteria are not in the urine but they have to come from somewhere. Many bacteria can enter into the body from the skin around you genitals and through your rectum and finally the bacteria climbs up your urethra and into your bladder.

See a doctor to prescribe for you some medication that will quickly eliminate the urinary tract infection. A urinary tract infection will normally clear up with few days if it is treated with proper medication.

You should know that the longer you hold it the bladder, the more likely you are giving the chance to bacteria to develop in the bladder. The more you pee the better and more you clear out your system to feel relieved to curve the infection of bright yellow urine. It is important to keep in this in mind even to people who may like to hold urine much more than urinating.

  • Bilirubin, a yellow pigment is formed as a result of the breakdown of dead red blood cells in the liver. Jaundice normally may occur when the liver fails to break down bilirubin properly in the body. Jaundice may arise due to reasons like: too many bilirubins trying to enter into the liver at once, damaged liver cannot break down bilirubin, the bilirubin not being able to make it to the digestive tract to be removed through the stool
