Black stools what does it mean

Genetics Home Reference define ulcerative colitis as a gastrointestinal disorder that causes ulcers to form within the large intestine. NIDDK note that the cause of ulcerative colitis is unclear. Doctors can treat the condition with medications and surgery.

Colon polyps can cause blood in the stool, giving it a black, tarry appearance. These polyps are small growths that form in the large intestine.

They are not necessarily cancerous, but they can become cancerous over time. NIDDK report that these problems can include esophageal varices and gastroesophageal reflux.

Liver issues can cause esophageal varices, which are enlarged veins in the esophagus. Treatment will focus on stopping the bleeding and resolving the underlying condition that is causing the esophageal varices. If a person experiences gastroesophageal reflux frequently, they may have gastroesophageal reflux disease GERD.

The key causes are complications from certain medications, smoking, or increased pressure in the abdomen. This pressure can result, for example, from being overweight or pregnant. A person can often manage GERD by avoiding certain foods and not overeating. A doctor may also prescribe medications.

NIDDK note that the long-term use of some drugs, such as ibuprofen and aspirin , can cause stomach ulcers. A bacterial infection can also be a cause. If a doctor thinks that drugs such as ibuprofen or aspirin are causing stomach ulcers, treatment usually involves no longer using these pain relievers.
