Colors and smells of urine and stool: when is medical advice necessary?

Observing your own body can be a real challenge for some people. Especially when it comes to the colors of urine and stool, many people can quickly become concerned if they change. But not every change is a cause for concern. In this article you will learn what shades are common and when it is advisable to seek medical help.

The most important thing is to understand the basic color variations. According to urologist Prof. Axel Merseburger from Lübeck, urine should usually be light yellow or clear. A deep yellow color often indicates that fluid intake was inadequate. If you normally drink enough water, i.e. at least 1.5 liters of water per day, and still notice a persistent dark color, this could indicate health problems with the liver or bile.

Causes of color changes in urine

Orange urine can be the result of taking dietary supplements, such as beta-carotene, or the effects of certain medications, such as antibiotics. Other medications, such as the antidepressant amitriptyline, should not be ignored as they can also affect the color of urine.

If your urine takes on a pink hue, it could simply be due to eating blueberries. Reddish colors are also not always worrying. According to Merseburger, eating beetroot can cause such an effect. Extreme amounts of raspberries can also affect the color of urine.

However, it is crucial to observe the clues because woe betide you if the discoloration persists for a long time. If the unusual color of the urine lasts two to three trips to the toilet, a visit to the doctor is essential. Blood in the urine could be a symptom of serious medical conditions such as kidney disease or bladder cancer.

Changes in the smell of urine

In addition to color, some people are concerned about the smell of their urine. Normally, fresh urine hardly has any distinctive smell. But the smell can change as urine is broken down by bacteria. Changes in smell are often only temporary and can often be attributed to diet - a classic example is the characteristic smell of asparagus.

But caution is advised if the urine takes on a fishy smell. This could mean that there is a urinary tract infection or a bladder infection. An unpleasant smell of rotten eggs is a warning sign and should be examined carefully as it can indicate serious illnesses.

Although the color of the chair is important, it is often overlooked. Healthy stools range from light to dark brown and should be neither too hard nor too runny. Here it is important to pay attention to the lighting conditions - green colors can indicate the consumption of certain vegetables such as kale or spinach. Meanwhile, reddish stools most likely indicate consumption of beetroot.

However, permanent changes in stool color can be concerning. If diarrhea occurs at the same time, a gastrointestinal infection could be present. If the stool is also discolored, it is necessary to point out possible problems with the bile fluid. Blood in the stool is an immediate warning signal that requires immediate medical evaluation as it can indicate serious illnesses such as colon cancer.

When should you go to the doctor?

It is important to remain calm in such situations. If discoloration occurs, first stop and examine your diet. If you cannot find clear evidence of the color change within two to three trips to the toilet, it is advisable to see a doctor. Regular check-ups are crucial, especially for children and young people, in order to identify any problems at an early stage. Parents should be allowed to address concerns about the appearance or smell of their children's excreta during these examinations to provide reassurance.

Ultimately, the attention paid to one of the most personal aspects of our health – excretions – reflects a growing awareness of one's body. Regular checks and vigilance can be crucial in detecting illnesses at an early stage and ideally preventing them.

Causes of changes in urine and stool color

The color of urine and stool can be influenced by various factors. When it comes to urine, frequency of fluid intake, diet and medication are primary influencing factors. Consuming certain foods, such as asparagus or beetroot, promotes specific and sometimes noticeable changes in color. Certain medications, particularly diuretics and antibiotics, can also play a role.

The causes of changes in bowel movements are similar. Factors such as the proportion of fiber-rich food, the fat content of the food and the presence of food intolerances or allergies can influence the color of the stool. A sudden change in color may indicate symptoms of diseases such as cholecystitis (inflammation of the gallbladder) or pancreatitis (inflammation of the pancreas).

Changes in the microbiome and their relevance

Studying the microbiome, i.e. the community of microbes in the human body, is becoming increasingly important to understand well-being. An imbalance in the microbiome can lead to various abnormalities in digestion, which can change both the color and smell of urine and stool. Current studies have shown that the microbiome is crucially involved in digestion and nutrient absorption and therefore also significantly influences excretory functions.

A change in the microbiome due to diet, stress or illness can lead to unpleasant symptoms and should be monitored by a doctor.

Statistical findings on stool and urine tests

In order to obtain an overview of the frequency of diseases associated with changes in urine and stool color in Germany, health statistics generally use data from routine examinations and clinical studies. According to a 2021 survey by health insurance companies, approximately 10% of patients who presented with a urinary tract infection and approximately 5% of patients with persistent changes in bowel movements were classified as potentially serious.

Additionally, studies show that approximately 15% of adults experience symptoms of indigestion each year, with discoloration of stool and urine being among the most common anecdotal complaints.

The influence of lifestyle and diet on excretions

Lifestyle has a significant influence on health and the properties of urine and stool. A balanced diet rich in fiber, vitamins and minerals can help optimize digestive health while promoting the normal coloring of waste. Less natural or heavily processed foods, as well as excessive consumption of sugar and trans fats, can negatively influence the health of the microbiome and the associated excretion products.

Regular exercise and sufficient fluid intake also support the optimal functioning of the digestive system and have a positive effect on the color of stool and urine.
