Dark stools, also known as hair, are a condition in which stool seems darker than usual due to the presence of digested blood. This change in the color of the feces can be alarming and indicate an underlying medical condition. Understanding the causes, symptoms and options for the treatment of dark color feces is essential for a rapid diagnosis and proper treatment.

Dark stools may be due to several causes, both benign and more serious. A frequent cause is the ingestion of certain foods and medications. Iron supplements, substances containing bismuth, such as pepto-bismol, and some dark color, such as blueberries and licorice, can give a black color to feces. However, if the darkening of feces is not attributed to dietary factors, it is important to consider other causes.

Understanding Dark Coloured Stool

The color of the feces depends mainly on the presence of bile, a digestive liquid produced by the liver. Normally, the feces are brown due to the decomposition of red blood cells and the oxidation of bile pigments. However, when the feces appear dark, they indicate the presence of digested blood in the gastrointestinal tract, which can be indicative of an underlying health problem.

Important note: Dark color stool should not be ignored, since they can be a sign of hemorrhage in the upper gastrointestinal tract, including esophagus, stomach or the small intestine. Immediate medical care is crucial to identify the cause and initiate proper treatment.

  • Causes: There are several possible causes of dark color feces, including gastrointestinal bleeding, certain medications, iron supplements, the consumption of certain foods, such as red wine or black licorice, and certain medical conditions, such as peptic ulcers or stomach cancer.
  • Symptoms: In addition to the change of color of the feces, people can experience symptoms such as abdominal pain, nausea, vomiting, dizziness, fatigue or fainting. It is important to be attentive to these symptoms and inform them to a healthcare professional.
  • Possible complications: dark color feces can indicate an underlying disease that may require immediate medical intervention. Ignoring this symptom can cause complications such as anemia, serious hemorrhages or drilling of the gastrointestinal tract. Precho detection and treatment can help prevent these complications.

It is crucial to consult a healthcare professional if dark color feces are observed, especially if they persist or are accompanied by other worrying symptoms. A rapid diagnosis and treatment can help identify the underlying cause and prevent subsequent complications.

Common Causes of Dark Coloured Stool

1. Gastrointestinal hemorrhage: One of the main causes of dark color is gastrointestinal bleeding. This can occur in various parts of the digestive system, such as esophagus, stomach, small intestine or the large intestine. The presence of blood in the upper gastrointestinal tract, such as stomach or esophagus, usually causes black and tarry feces. On the other hand, bleeding in the lower gastrointestinal tract, such as colon or rectum, usually lead to bright red blood mixed with stool.

It is essential to seek immediate medical attention if persistent dark stool accompanied by other alarming symptoms such as dizziness, abdominal pain or significant weight loss are observed.

2. Iron supplements or certain medications: the consumption of iron or medication supplements containing bismuth subsalicylate, such as pepto-bismol, can also cause dark color feces. Iron supplements often cause a dark green or gree n-green change, while medications containing bismuth subsalicylate can cause feces to acquire a black or gray color.

Medical Conditions Associated with Dark Coloured Stool

A frequent cause of dark color feces is gastrointestinal bleeding, which occurs when there is bleeding in the digestive tract. This can cause the presence of digested blood in feces, which gives rise to its dark appearance. Gastrointestinal bleeding may be due to various conditions, such as peptic ulcers, gastritis, esophageal varicose veins and diverticulosis. It is important to seek medical evaluation if dark feces persist or are accompanied by symptoms such as abdominal pain, dizziness or weakness.

The presence of dark stool can also be indicative of liver disorders. Hepatic diseases such as hepatitis, cirrhosis and liver cancer can cause dark feces due to insufficient bile production, a substance responsible for giving feces their typical brown color. In these conditions, the absence of bile or the presence of bilirubin in the stool can lead to darker tones. A rapid medical evaluation is necessary to diagnose and treat these possible liver disorders.

Ulcers, gastritis, varicose veins and diverticulosis can cause gastrointestinal bleeding that give rise to dark color stool.

Hepatic diseases such as hepatitis, cirrhosis and liver cancer can cause dark feces due to insufficient bile production.

In some cases, dark color feces can indicate a hemorrhage in the upper digestive tract. This can be associated with conditions such as stomach or esophagus cancer, which require thorough investigation and proper treatment. Other factors that can contribute to the appearance of dark feces are the use of certain medications, such as iron supplements or certain analgesics, as well as the ingestion of certain foods or food coloring. However, it is essential to differentiate between benign causes and more serious medical conditions by going to the doctor and undergoing relevant diagnostic tests.

  1. Hemorrhages of the upper digestive tract can cause dark color feces and may be associated with cancer.
  2. Medications, dietary factors and food dyes can contribute to dark feces, but underlying medical conditions must be ruled out.
Possible causes Symptoms
Gastrointestinal bleeding Abdominal pain, dizziness, weakness
Liver disorders Insufficient bile production, presence of bilirubin
Upper gastrointestinal bleeding Possible association with cancer
Medications, dietary factors and food coloring No specific symptoms

When to Seek Medical Help for Dark Colored Stool

1. Blood in stool: If you notice dark-colored blood in your stool, it is important to seek immediate medical attention. Blood in stool can have several causes, such as gastrointestinal bleeding, hemorrhoids, or even certain types of cancer. The presence of blood may be indicated by a bright red color or a black, tarry appearance.

When there is visible blood in dark-colored stools, it is crucial to consult a healthcare professional as soon as possible. Prompt evaluation and diagnosis are necessary to identify the cause and initiate appropriate treatment.

2. Severe abdominal pain or cramps: If your dark-colored stools are accompanied by severe abdominal pain or cramps, it could be a sign of a more serious condition. Conditions such as inflammatory bowel disease, diverticulitis, or intestinal obstruction can present these symptoms. It is important not to ignore any persistent or worsening abdominal pain.

3. Changes in bowel habits: If you experience significant changes in your bowel habits along with dark-colored stools, it may indicate an underlying problem. This includes persistent diarrhea, constipation, or unexplained changes in the frequency or consistency of your bowel movements.

  1. If you notice any of these changes in bowel habits and they persist for more than a few days, it is advisable to seek medical help.

In summary, although occasional changes in the color of the feces are usually benign, the persistent or recurrent dark feces can justify a more thorough investigation. If blood stools experience, experience intense abdominal pain or has significant changes in your intestinal habits, it is important that you consult a healthcare professional for a timely evaluation and proper treatment.
