Recognizing the Signs: Key Symptoms of Ulcerative Colitis
Published: Feb 25, 2024
Ulcerative colitis can cause a range of digestive and systemic symptoms. Recognizing these signs is crucial for early diagnosis and treatment.
Contents
Digestive Symptoms
The hallmark symptoms of ulcerative colitis are diarrhea and rectal bleeding. Patients often experience frequent, loose stools that may contain blood, mucus, or pus. Abdominal pain, especially in the lower left side, is common. Many also feel an urgent need to have a bowel movement and may have tenesmus - a sensation of incomplete evacuation.
Systemic Symptoms
As ulcerative colitis is a systemic inflammatory condition, it can cause symptoms beyond the digestive tract. These may include fatigue, fever, and unintended weight loss. Some patients experience a loss of appetite or nausea. In severe cases, rapid heart rate and anemia due to blood loss can occur.

Extraintestinal Manifestations
Ulcerative colitis can affect other parts of the body. Some patients develop joint pain or arthritis, especially in large joints like knees or elbows. Eye inflammation, skin rashes, and liver problems are also possible. These symptoms may come and go along with intestinal flares or occur independently.
