Proctitis

Symptoms

Proctitis symptoms may include:

• A frequent or continuous feeling that you need to pass stool.
• Rectal bleeding.
• Passing of mucus through the rectum.
• Rectal pain.
• Pain on the left side of the belly.
• A feeling of fullness in the rectum.
• Diarrhea.
• Pain with bowel movements.

Causes

Several conditions, treatments and other factors can cause proctitis, including:

• Inflammatory bowel disease (IBD). About 30% of people with IBD have inflammation of the rectum. This is more common in people with ulcerative colitis than in those with Crohn's disease.
• Infections. Sexually transmitted infections (STIs) can result in proctitis. These infections happen particularly in people who engage in anal intercourse. Types of STIs that can cause proctitis include gonorrhea, genital herpes, monkeypox and chlamydia. Infections associated with foodborne illness, such as salmonella, shigella and campylobacter infections, also can cause proctitis.
• Antibiotics. Sometimes antibiotics used to treat an infection can kill helpful bacteria in the bowels, allowing harmful Clostridioides difficile bacteria to grow in the rectum and the colon.
• Surgery. A type of proctitis called diversion proctitis can happen in people after certain small intestine or colon surgeries. In these surgeries, the passage of stool is diverted from the rectum to a surgically created opening, called a stoma.
• Food proteins. Food protein-induced proctitis can happen in infants who drink either cow's milk- or soy-based formula. Infants breastfed by mothers who eat dairy products also may develop proctitis.
• Buildup of white blood cells. Eosinophilic proctitis happens when a type of white blood cell called an eosinophil builds up in the lining of the rectum. Eosinophilic proctitis more commonly affects children younger than 2 rather than older individuals.

Complications

Proctitis that isn't treated or that doesn't respond to treatment may lead to complications, including:

• Anemia. Chronic bleeding from the rectum can cause anemia. With anemia, there aren't enough red blood cells to carry oxygen to the tissues. Anemia causes someone to feel tired and possibly have dizziness, shortness of breath, headache, a change in skin color, and irritability.
• Ulcers. Long-lasting inflammation in the rectum can lead to open sores, called ulcers, on the inside lining of the rectum.
• Fistulas. Sometimes ulcers extend completely through the intestinal wall. This can create a fistula, an irregular connection that forms between different parts of the intestine, between the intestine and skin, or between the intestine and other organs, such as the bladder and vagina.

Treatment

Treatment for proctitis depends on the cause of the condition.

Treatment for proctitis caused by an infection

For proctitis caused by infection, medicines may be recommended. Options may include:

• Antibiotics. For proctitis caused by certain bacterial infections, an antibiotic such as doxycycline (Oracea, Vibramycin, others) may be given.
• Antivirals. For proctitis caused by viral infections, such as the sexually transmitted herpesvirus, an antiviral medicine such as acyclovir may be prescribed.

Treatment for proctitis caused by radiation therapy

Mild radiation proctitis may not need treatment. But radiation proctitis also can cause serious pain and bleeding that need treatment. A healthcare professional may recommend treatments such as:

• Medicines. Medicines are given in pill, suppository or enema form. They include sucralfate, mesalamine, sulfasalazine and metronidazole. These medicines can help control inflammation and reduce bleeding.
• Stool softeners and dilation. These can help stool pass easier, decreasing pain.
• Ablation. Ablation improves proctitis symptoms by destroying damaged, bleeding tissue. Ablation procedures used to treat proctitis include argon plasma coagulation and other therapies.

Proctitis caused by inflammatory bowel disease

Treatment of proctitis related to ulcerative colitis or Crohn's disease focuses on reducing inflammation in the rectum. Treatment may include:

• Medicines to control rectal inflammation. A healthcare professional may prescribe anti-inflammatory medicines, either by mouth or as suppositories or enemas. These include mesalamine or corticosteroids. Corticosteroids include prednisone or budesonide.

  Inflammation in people with inflammatory bowel disease often needs treatment with a medicine that suppresses the immune system, such as azathioprine or infliximab.

• Surgery. If medicine doesn't relieve symptoms, surgery to remove a damaged portion of the digestive tract may be done.

Preparing for your appointment

Start by seeing your healthcare team if you have rectal pain or bleeding, or if you constantly feel the need to pass stool. If your care team suspects that you have proctitis, you may be referred to a doctor who specializes in diseases of the digestive system, called a gastroenterologist.

Here's some information to help you get ready and to know what to expect.

What you can do

• Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet.
• Write down any symptoms you're experiencing, including any don't seem related to the reason for which you scheduled the appointment.
• Write down key personal information, including any major stresses or recent life changes.
• Make a list of all medicines, as well as any vitamins or supplements, that you're taking.
• Take a family member or friend along to help you remember everything you and your healthcare team talk about.
• Write down questions to ask during your appointment.

Questions to ask your doctor

• Is proctitis causing my symptoms?
• What are possible causes for my proctitis?
• What kinds of tests do I need?
• What are my treatment options?
• What are the benefits and risks of each treatment option?
• I have other medical conditions. How can I best manage them while also managing proctitis?
• Are there any restrictions that I need to follow?
• Is there a generic alternative to the medicine you're prescribing?
• Are there any brochures or other printed material that I can take with me?
• What websites do you recommend?
• Should I plan for a follow-up visit?

Don't hesitate to ask other questions that you think of during the appointment.
