Why I See black specks in poop?

At some point in our lives, we’ve all taken a glance at our poop to assess our health. It might not be a pleasant topic, but it’s essential to pay attention to any changes in your bowel movements. So, what do black specks in your poop mean? In this article, we will explore the common causes, diagnosis, and treatment of black specks in poop.

Common causes of black specks in poop

Undigested food

Sometimes, black specks in poop are just undigested food particles. Certain foods, like blackberries, blueberries, or poppy seeds, can leave residue in your stool. If you recently consumed any of these, that could be the reason for the black specks.


Some medications can cause black specks in poop. Nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin, ibuprofen, and naproxen can cause gastrointestinal bleeding, which can appear as black specks in your stool.

Iron supplements

Iron supplements can darken your poop and cause black specks. This is usually harmless, but if you’re concerned, consult your doctor.

Bismuth-containing medications

Bismuth-containing medications, like Pepto-Bismol, can cause temporary black discoloration in your stool. This is harmless and should resolve once you stop taking the medication.

Peptic ulcers

Peptic ulcers are sores that form in the lining of the stomach or the upper part of the small intestine. They can cause gastrointestinal bleeding, which may result in black specks in your stool.

Esophageal varices

Esophageal varices are enlarged veins in the esophagus. They can bleed and cause black specks in your stool.


Diverticulitis is an inflammation or infection in the diverticula, small pouches that form in the walls of the large intestine. Sometimes, this condition can cause gastrointestinal bleeding, leading to black specks in the stool.

Helicobacter pylori

Helicobacter pylori (H. pylori) is a type of bacteria that can cause stomach ulcers and inflammation. In some cases, an H. pylori infection can lead to gastrointestinal bleeding and black specks in your poop.

Parasitic infections

Parasitic infections, such as giardiasis or amoebiasis, can cause inflammation and bleeding in the gastrointestinal tract, leading to black specks in your stool.


Hemorrhoids are swollen veins in the lower part of the rectum or anus. They can cause bleeding, which might appear as black specks in your poop.


Polyps are small growths in the lining of the colon or rectum. Some polyps can bleed, causing black specks in your stool.

Colorectal cancer

Colorectal cancer is a malignant tumor that starts in the cells lining the colon or rectum. Bleeding from colorectal cancer can lead to black specks in your poop.

Which Foods Make a Black Spot in Your Stool?

Fruits and seeds

Dark-colored fruits, such as blackberries, blueberries, and cherries, can cause black specks in your poop due to their pigments and small seeds. Likewise, eating foods containing poppy seeds or chia seeds may also result in black specks in your stool.

Dark leafy greens

Dark leafy greens like spinach, kale, and collard greens are rich in chlorophyll, which can darken your stool and cause black specks to appear.

Dark chocolate and cocoa

Dark chocolate and cocoa products can also cause black specks in your poop due to their dark pigments.


Black licorice contains a pigment that can darken your stool and cause black specks to appear.


we will discuss effective treatments for black specks in your stool based on their root cause.

Undigested food

If black specks in your stool are a result of undigested food, like seeds or dark-colored fruits, they will likely resolve on their own without treatment. However, you can try adjusting your diet by eliminating suspected foods or increasing your fiber intake to improve digestion.

Medications and supplements

If black specks in your stool are caused by medications like nonsteroidal anti-inflammatory drugs (NSAIDs), iron supplements, or bismuth-containing medications, consult your healthcare professional. They may recommend alternative medications or adjust your dosage to minimize side effects.

Gastrointestinal conditions and infections

For gastrointestinal conditions such as peptic ulcers, esophageal varices, or diverticulitis, your healthcare professional may prescribe medications to manage symptoms and treat the underlying issue. These may include:

  • Acid-reducing medications for ulcers
  • Antibiotics for bacterial infections
  • Laxatives or stool softeners for constipation

Colorectal conditions

Colorectal conditions like hemorrhoids, polyps, or colorectal cancer may require more specialized treatment, such as:

  • Over-the-counter creams or ointments for hemorrhoids
  • Sclerotherapy or rubber band ligation for hemorrhoids
  • Surgical removal of polyps or cancerous tissue
  • Chemotherapy or radiation therapy for cancer

Lifestyle changes to support digestive health

In addition to treatments tailored to the specific cause of black specks in your stool, certain lifestyle changes can help support digestive health:

  • Stay hydrated by drinking enough water throughout the day
  • Consume a high-fiber diet with plenty of fruits, vegetables, whole grains, and legumes
  • Exercise regularly to promote healthy digestion and bowel movements
  • Manage stress through relaxation techniques like deep breathing exercises, meditation, or yoga
  • Maintain a healthy weight to reduce the risk of developing digestive issues

Natural Home Remedies for Black Specks in Poop

Although black specks in poop can sometimes indicate an underlying health issue, they may also be a result of your diet or harmless factors. If you believe your diet is causing the black specks, you can try some natural home remedies to address this issue

Increase your water intake

Dehydration can affect your digestion and lead to changes in your bowel movements. Make sure you drink enough water throughout the day to maintain proper hydration and support healthy digestion.

Consume more fiber

A diet low in fiber can cause constipation or irregular bowel movements, which may contribute to black specks in your stool. Increase your intake of fiber-rich foods such as fruits, vegetables, whole grains, and legumes to support regular bowel movements and overall digestive health.

Eliminate potential food triggers

If you suspect that certain foods are causing black specks in your poop, try eliminating them from your diet for a short period to see if the issue resolves. Common food triggers include dark-colored fruits (e.g., blackberries, blueberries), seeds (e.g., poppy seeds, chia seeds), dark leafy greens, and dark chocolate.


Probiotics are beneficial bacteria that can support a healthy gut microbiome, which plays a crucial role in digestion. Include probiotic-rich foods like yogurt, kefir, sauerkraut, kimchi, and kombucha in your diet, or consider taking a probiotic supplement.

Regular exercise

Regular physical activity can help maintain healthy digestion and bowel movements. Aim for at least 30 minutes of moderate exercise most days of the week.

Manage stress

Stress can negatively impact your digestion and contribute to changes in bowel movements. Practice stress management techniques, such as deep breathing exercises, meditation, yoga, or other relaxation methods, to help support healthy digestion.

When to See a Doctor?

While black specks in your poop after eating certain foods are usually harmless, you should pay attention to any accompanying symptoms or persisting changes in your bowel movements. Consult a healthcare professional if you notice:

  • Black specks in your stool that persist even after eliminating the suspected foods
  • Abdominal pain or discomfort
  • Unexplained weight loss
  • Changes in bowel habits
  • Fatigue or weakness
