Ulcerative colitis


Ulcerative colitis is an inflammatory bowel disease (IBD) that causes chronic inflammation of the digestive tract, specifically the large intestine (colon) and rectum. Symptoms typically include abdominal pain, diarrhea (which may be bloody), and weight loss. Other symptoms can include fever, tiredness, and loss of appetite. In severe cases, there may be collections of pus in the colon called abscesses. In most cases, ulcerative colitis is managed with lifestyle changes and medications such as anti-inflammatories, immunomodulators, and biologic response modifiers. Surgery is typically necessary only when medications fail to control the inflammation.


The symptoms of ulcerative colitis can vary from person to person, but common symptoms include:

  • Ongoing diarrhea that may contain blood or pus
  • Abdominal pain and cramping
  • Rectal pain and bleeding
  • Urgency to have a bowel movement
  • Unexplained fatigue
  • Weight loss
  • Poor appetite
  • Anemia
  • Fever
  • Nausea and vomiting


The exact cause of ulcerative colitis is unknown, however, it is believed to be an autoimmune disorder that is caused by a combination of genetic, environmental, and immunological factors. It is thought that an abnormal reaction of the body’s immune system towards its own intestinal tissue might lead to the inflammation and ulcers that are characteristic of ulcerative colitis. Certain environmental factors, such as stress, a diet high in processed or sugary foods, and smoking, may also play a role in the development of ulcerative colitis. Additionally, some studies have suggested that infections, such as a virus or bacteria, may be linked to the onset of ulcerative colitis.

Risk factors

The exact cause of ulcerative colitis is unknown, but there are some known risk factors that have been identified.

Common risk factors include:

  • Age – Ulcerative colitis is most common in people between the ages of 15 and 30, but can affect people at any age.
  • Genetics – Research suggests that ulcerative colitis can run in families, and one has a slightly increased risk of developing ulcerative colitis if a close relative has it.
  • Environment – Certain environmental exposures may increase the risk of ulcerative colitis. For example, smoking, stress, food allergies, and air pollution may all be associated with an increased risk.
  • Gender – Men are more likely to develop ulcerative colitis than women.
  • Race – Caucasians are more likely to develop ulcerative colitis than other races.
  • Autoimmune Disorders – People with other autoimmune disorders, such as Crohn’s disease, lupus, multiple sclerosis and type 1 diabetes, also have an increased risk of developing ulcerative colitis.
  • Medication – Non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with an increased risk of ulcerative colitis in some people.


Ulcerative colitis is typically diagnosed through a combination of a physical examination, medical history, and laboratory testing. A doctor may also order an endoscopic procedure to obtain a sample of tissue from the inside of the rectum and colon (known as a biopsy) to better diagnose the condition. Other tests that may be used include imaging tests like x-ray and MRI, blood tests to look for signs of inflammation, and stool tests to help rule out other conditions or infections. Depending on the severity of the condition, a doctor may also recommend additional tests to better understand the underlying cause of the inflammation.


There are four main subtypes of Ulcerative Colitis:

  1. Ulcerative Proctitis: This subtype is limited to the rectal area. Symptoms of this type include rectal bleeding, rectal pain, and a feeling of urgency to defecate.
  2. Proctosigmoiditis: This type affects the sigmoid colon and the rectum. Symptoms include abdominal cramps, weight loss, and bloody diarrhea.
  3. Pancolitis: This type affects the entire large intestine and may cause symptoms such as abdominal pain, loss of appetite, and bloody diarrhea.
  4. Fulminant Colitis: This type is the most severe form of ulcerative colitis, and can cause dehydration, fever, and rapid weight loss.


The treatment options for Ulcerative Colitis depend on the severity of the condition and can vary from person to person. Generally, treatment focuses on symptom relief and some sort of maintenance therapy to prevent flare-ups.

Common treatment options include:

  1. Medication: Antibiotics, immunosuppressants, and aminosalicylates are commonly used to help reduce inflammation in the intestines and to prevent flare-ups.
  2. Diet: A healthy, balanced diet can help reduce symptoms of UC. Identifying and avoiding trigger foods can help reduce flare-ups and keep symptoms at bay. This may include avoiding or limiting processed and fatty foods, sugary foods, dairy, caffeine, and alcohol.
  3. Stress Management: Stress can often cause or worsen symptoms of UC. Therefore, learning stress-management techniques, such as meditation, deep breathing, and yoga, can help reduce flare-ups of UC.
  4. Surgery: Surgery may be recommended for people with Ulcerative Colitis when other treatments have failed to provide relief from symptoms. Surgery may involve the removal of the colon, rectum, and other parts of the digestive tract.


  1. Eating a balanced, nutritious diet and avoiding processed, fried, and fatty foods can help to reduce the risk of ulcerative colitis.
  2. Avoiding foods that cause gastric irritation, such as spicy or acidic foods, can help to reduce symptoms.
  3. Limiting your intake of alcohol and caffeine can also help to reduce the risk of ulcerative colitis.
  4. Incorporating stress-reducing activities such as yoga, meditation, or deep breathing can help to reduce flare-ups and reduce the risk of ulcerative colitis.
  5. Exercising regularly and maintaining a healthy weight can help to reduce the risk of ulcerative colitis.
  6. Supplementing with probiotics can help to regulate the balance of good and bad bacteria in the gut, which may help to reduce the risk of ulcerative colitis.

Gender differences?

Yes, there are gender-specific differences in the presentation and management of Ulcerative Colitis. Men are more likely to have symptoms of bloody diarrhea, while women are more likely to have symptoms of abdominal pain and fever. Men also tend to have a more severe course of disease, with a higher risk of hospitalization and the need for surgery, while women may experience less severe symptoms and may be able to control the disease with medications. Additionally, women may be more likely to suffer from anemia due to the disease and may require more frequent dose adjustments of medications.


Nutrition plays a critical role in the management of ulcerative colitis as it is important to provide the body with the necessary nutrients to support healing and maintain overall well-being. Maintaining a balanced and varied diet is recommended to ensure an adequate intake of essential vitamins and minerals including protein, iron, zinc, folic acid, and vitamins A, C and E. Additionally, some studies suggest that certain food items may reduce inflammation and improve the symptoms of ulcerative colitis, such as probiotics, fiber-rich foods, and foods containing omega-3 fatty acids. It is important to work with a dietitian to determine the best diet for an individual with ulcerative colitis, as dietary modifications and supplements may be necessary to manage symptoms.

Physical Activity

Physical activity can have a positive effect on ulcerative colitis by improving symptoms, reducing inflammation, and decreasing the risk of hospitalization. Regular exercise has been shown to reduce abdominal pain, reduce fatigue, decrease stress, and improve overall quality of life. In addition, physical activity can also reduce inflammation in the intestines and improve the body’s ability to absorb nutrients. Regular aerobic exercise has been found to be particularly beneficial for people with UC, as it increases cardiovascular endurance, reduces fatigue, and helps to lower stress levels. Finally, physical activity can also reduce the risk of hospitalization by helping to control flare-ups and prevent disease progression.
