What does the color of urine during pregnancy indicate, and what should it be normally?

One obvious change that can occur in a woman’s body during pregnancy is the color of her urine. It’s normal to wonder what this could mean and whether there’s cause for concern.

Urine color can change for a number of reasons, including medication, diet, and level of hydration. Changes in hormones during pregnancy also have an impact. While certain changes are benign, others might indicate a problem that needs to be addressed.

Any concerns can be reduced by knowing what’s normal and when to see a doctor. Let’s examine what various urine colors might mean as well as what is typical for pregnant women.

Why does urine change color?

When something "interesting" happens, urine changes color. And there are a lot of causes behind this. Pregnancy causes a significant "restructuring" of the body, with all of the organs and systems functioning differently. To preserve as much energy and nutrition as possible for the fetus developing beneath the woman’s heart, many of them go into "saving" mode.

Hormone levels fluctuate, urine’s actual composition changes, and the body’s metabolic processes take on new directions. Urine’s color cannot be unaffected by all of this.

Women also take note of the fact that the excreted fluid’s color is highly unstable and varies with each visit to the doctor since excretory fluid analysis is the most common test performed before a visit.

The color of urine is affected by many things:

• The presence of toxicosis.Nausea, lack of appetite lead to moderate dehydration. Because of this, urine becomes more concentrated, bright.
• Drinking regime. If pregnancy falls on the hot summer months, when fluid loss with sweat is higher, if a woman drinks little water, urine again becomes more concentrated. And if a woman drinks a lot, then the color of the excreted fluid becomes less saturated.

• Some medications. Many drugs can change the color of urine – antihistamines, calcium preparations, vitamins. By the way, folic acid, recommended for all expectant mothers, also makes the color of urine brighter.
• Food. If a woman in an "interesting" position has a passion for beets, carrots, pomegranate, garlic, then a change in the color of urine is a completely natural consequence of eating these products. Beets, for example, make urine red, and carrots – bright orange.
• Baby"s metabolism. The products of the child"s metabolism are excreted through the umbilical cord and placenta into the mother"s blood, and from there – into the urine. That is why the color of urine changes during pregnancy.

• Gestosis. In the second and third trimester, a change in the color of the fluid excreted by the kidneys can be an indirect sign of gestosis. If a new shade of urine is accompanied by edema, instability of blood pressure, the woman needs qualified medical care.
• Hypertension. High blood pressure also changes the shade of the excreted fluid. In this case, it is necessary to find the cause of the increase in pressure, correction of this indicator will help normalize the color and shade.
• Diseases of the kidneys, ureters, urethra. Any deviations in the functioning of the urinary system are necessarily reflected in the color of urine. The shade of urine in this case depends on the specific disease. With some pathologies, blood appears in the urine, with others – sediment, pus.

There are numerous variables that affect the color, including:

• the woman"s metabolism – the rate of metabolic processes in her body;
• the presence of viral or other infectious diseases;
• normal functioning of the liver, gall bladder;
• possible blood diseases.

Norms

Urine’s color is ascertained through a general analysis. This indicator is of particular interest to diagnosticians. There is a unique color scale, similar to a graphic designer’s palette, to evaluate the color. Transparency, the consistency of dissolved materials, and color intensity all affect color.

Special pigments called urochrome, uroerythrin, urosein, and stercobilin give urine its color. There are many different shades of yellow produced by varying the quantities of these pigments.

The morning portion of urine is thought to be the most concentrated, so it’s crucial to give it to the lab in order to accurately determine the shade of the expelled liquid. Furthermore, it must be delivered as soon as possible, but no later than two hours following collection. The test results won’t be trustworthy otherwise.

After being in the jar for longer than two hours, the liquid starts to ferment and decay the dissolved substances, which break down into tiny pieces and urine-coloring pigments. This distorts the color of the liquid and prevents the laboratory assistant from getting accurate and instructive research results.

Urine color norms are based on a rather nebulous concept of "norm." Everybody has a different norm. You must consider his lifestyle, diet, and medications in order to determine whether or not his color is normal.

In general, normal urine for pregnant women is thought to be a straw-colored liquid with a light yellow tint. Another common variation is a yellow that is more saturated. Pink and reddish urine can coexist as normal at times. However, unclean brown, greenish, hazy hues, and pee containing white fragments do not fall within the typical range.

Urine color can reveal information about a woman’s diet, level of hydration, and even possible health issues during pregnancy. Light yellow urine indicates adequate hydration, but other factors such as supplements, medications, or specific foods can cause a change in urine color. While slight variations in urine color are common, persistent changes should be discussed with a healthcare professional to rule out any underlying problems, particularly if the change is dark, hazy, or accompanied by pain.

What does the color of urine indicate?

A woman is always curious as to what could have caused her urine to change color. Laboratory diagnostics can provide the most accurate answer because they enable you to assess not only the color and transparency but also the primary quantitative indicators and the salt and other substance content. We will discuss with you the most popular choices for color for the expelled liquid.

Red

Typically, red or burgundy liquids are only possible after consuming red food dye-containing dishes like borscht or beet salad. The red color of the urine is a very concerning sign that there may be blood in it if the expectant mother did not eat any of these foods the day before the analysis.

When there is mechanical trauma to the urinary tract, such as "sand" or "stone" in urolithiasis, which is quite common in pregnant women, red blood cells may appear in the excreted fluid.

Red pee may be a sign of a tumor growing within the body, as well as inflammation and injuries to the kidneys, ureters, urethra, or genitalia.

The most common cause of red urine in pregnant women is oxalates, which are sharp, uneven stones that hurt mucous membranes as they pass through the urinary tract and release a lot of red blood cells into the urine.

Renal colic may accompany the condition, or it may be entirely asymptomatic—that is, exhibiting only red urine and no other symptoms of any disorders. Blood clots in the urine can occasionally affect the ureters’ ability to stay open. Urinary retention symptoms start to show, and the liquid eventually turns red.

Urine takes on different shades of red depending on the presence of red blood cells. If the urine has an unclean, reddish-brown tint, myoglobin is probably present in the excreted fluid. This could be a sign of damage to the urinary system’s muscle tissue or the aftereffects of the syndrome caused by prolonged compression of its component parts.

One should see a nephrologist if they have red urine. The emergence of such a symptom is typically linked to conditions like glomerulonephritis, cystitis, urolithiasis, and pyelonephritis.

It’s critical to assess other symptoms, such as swelling, lower abdominal pain, fever, pain in the lumbar area, burning during and after urination, and pain during the process.

When red blood cells are found in the fluid that the kidneys excrete, mandatory diagnostic tests are necessary to determine the true cause, even in cases where the temperature is normal and there is no pain.

Orange

The pigments urobilinogen and urrochrome give the secreted fluid its rich orange color. When a woman includes carrots and carrot juice, oranges, and canned food with a fairly high content of various preservatives in her diet, they are expelled from the blood in large quantities.

The bright color could indicate that the body is dehydrated if such food was not consumed the day before. Some women "prepare" for their next doctor’s appointment by cutting back on fluid intake and fasting days in order to prevent swelling and excessive weight gain.

Even a small amount of drinking can cause dehydration, especially in the summer, when the specific gravity of the substances dissolved in the urine increases, turning it a bright orange color.

Orange urine is a phenomenon that expectant moms who enjoy saunas and baths may experience. Some people struggle to break this habit, even when they are pregnant. Urine production is also decreased and becomes more concentrated when sweating increases.

When taking multivitamins, especially those with higher B vitamin content, urine turns orange. When taking folic acid in the first trimester of pregnancy, which is advised for all expectant mothers to prevent neural tube defects in the developing fetus, bright yellow and orange urine is the natural result.

The presence of bilirubin in the blood can cause urine to turn orange if the liver or gallbladder are not operating normally. Large amounts of this pigment, which is created when some proteins, like hemoglobin, break down, can be produced in certain blood disorders.

Amber in color, fluid with elevated bilirubin levels. The material for laboratory diagnostics forms a small amount of yellow foam when you shake the jar containing it.

Colorless, white

Colorless urine is typically defined as having no color at all or as being white in hue. Lymph enters the secreted fluid and changes urine to resemble milk. Certain diseases of the kidneys and bladder make this feasible.

A significantly enlarged uterus during late pregnancy may compress the lymph duct, which may result in lymph getting into the urine.

When there is an internal kidney abscess, the fluid may turn white and amorphous. Although rare, the condition is thought to be highly dangerous. The lady needs emergency medical attention.

Pregnant women who drank a lot of liquid the day before collecting fluid for analysis can see transparent urine, which is essentially devoid of pigments. And maybe there isn’t another physiological explanation. The remainder are illness indicators. Diabetes mellitus, including gestational diabetes in pregnant women, results in colorless urine and renal failure.

Brown

Severe dehydration may be indicated by dark urine. Usually, after the drinking regimen is optimized, its color returns to normal. It has been observed that pregnant women who are constipated and using laxative teas have brown urine. Rectal suppositories are therefore preferable since they effectively relax the intestines without changing the color of the urine.

When taking drugs that contain a lot of B vitamins or eating a lot of garlic, urine turns brown. A significant ascorbic acid dosage and iron supplements may also result in a browning of the skin tone.

Dangerous illnesses like cholelithiasis, hepatitis B and C, liver tumor processes, and pancreatic disorders are not at all low on the list of pathogenic causes. Such fluid may coexist with blood disorders linked to severe and quick erythropoiesis of the red blood cells.

For women who have experienced toxic poisoning, such as mercury vapor, a dark shade is typical. When a pregnant mother has an infectious urinary tract lesion, her urine turns brown.

Pink

Although it may seem a little scary, pink secreted fluid typically does not signify any illness. Urine typically turns pink the day after the expectant mother consumed red food coloring-infused candies, canned meat, cherries, or blackberries.

When taking medications like "Ibuprofen" or those containing acetylsalicylic acid, urine turns pink.

There’s no need to worry if the pink color turns into a typical yellow in any shade within a few hours.

You should be concerned about the state and functionality of the kidneys, bladder, and ureters if there is a propensity for the color of urine to change to a brighter, redder hue.

A pregnant woman should have an ultrasound of her kidneys and bladder done right away, and the results should be used to schedule an appointment with a non-fraud doctor, should her face, arms, or legs swell in the morning, should she start using the restroom more frequently than usual, should her blood pressure rise, or should the fluid itself take on an offensive pungent odor.

Green and blue-green

Pus impurities are characterized by all shades of green. Such procedures are usually not ignored; in addition to the fluid’s unusual hue, the woman exhibits all the symptoms of purulent genitourinary system inflammation, including a high fever, excruciating pain, and swelling. The blue-green liquid uses a pseudoscientific stick to talk about infection.

Blue

Though extremely uncommon, heavenly-colored urine can also occur. Certain medications, such as "phenacetin," vitamin complexes, and antibiotics (tetracycline), if prescribed by a pregnant woman with diabetes under certain circumstances, can paint urine a strange color.

It is extremely uncommon for a metabolic disease to cause an excessive buildup of tryptophan protein. Eating turkey, chicken, fish, and seafood will facilitate the accumulation of protein that turns urine blue if the expectant mother has this kind of pathology.

Determination of gender

Whether gender influences urine color is a question that many expectant mothers are curious about at the start of the gestation period, when there is really no other way to find out the baby’s gender. Expectant mothers’ forums are frequent places for discussion of these matters. Pale, nearly colorless pee may be an indication that a girl is growing in the womb, and bright colors are said to be a sign of carrying a son.

These claims make no sense when viewed through a medical lens. Since the color of the fluid secreted by the kidneys is formed by entirely different factors—as we have already discovered—there is not a single plausible explanation that supports such a gender diagnosis.

However, this is a fun way to tell fortunes; similarly, the Chinese table, blood table, and wedding ring vibrations on a thread above the stomach can all be used to determine gender. Since there are only two possibilities, the gender diagnosis by urine color is precisely 50% accurate.

Color of Urine	Possible Indication
Pale Yellow	Normal hydration, healthy pregnancy
Dark Yellow	Dehydration, need to drink more water
Orange	Vitamin supplements or dehydration
Red or Pink	Possible blood in urine, consult a doctor
Brown	Liver issues, seek medical advice
Green or Blue	Rare, could be due to medications or food dyes

Changes in urine color during pregnancy can be caused by a number of things, including foods, vitamins, and even fluid levels. Even though some variances are perfectly normal, it’s crucial to be aware of any significant changes and, if necessary, seek medical advice.

Light yellow or clear urine typically indicates adequate hydration, while darker urine may indicate dehydration. But if pee turns extremely dark, reddish, or hazy, it might indicate an underlying problem that needs to be looked at by a physician.

In general, one easy way to keep an eye on your health during pregnancy is to pay attention to the color of your urine. Never be afraid to ask your healthcare provider for advice and reassurance if you have any concerns.
