An IV is a small tube placed in your vein that is used to give you medicine, liquids, or nutrition. You may not be able to eat or drink anything until your healthcare provider says it is okay.


  • Antibiotics help treat or prevent a bacterial infection.
  • Pain medicine may be given. Do not wait until the pain is severe before you ask for more medicine.


  • Blood and urine tests may show infection or give information about your overall health.
  • CT scan or ultrasound pictures may be used to find problems in your intestines. You may be given contrast liquid to help your intestines show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid.
  • A colonoscopy may be used to look at your intestines with a scope. A scope (long bendable tube with a light on the end) is used to take pictures. This test may show swollen diverticula or bleeding. Samples may be taken from your digestive tract and sent to a lab for tests. Bleeding may be controlled with tools that are inserted through the scope.


  • A clear liquid diet may help your intestines heal. Your healthcare provider will tell you when it is okay to eat solid foods again.
  • A nasogastric (NG) tube may be inserted to let your intestines rest. An NG tube is a thin tube that is inserted through your nose and into your stomach. It helps remove fluid and air.
  • Drainage of an infected diverticula may be done to reduce inflammation or treat infection. Your healthcare provider may insert a small tube through an incision in your abdomen to drain pus from diverticula.
  • Surgery may be needed if there is a hole in your bowel or a large amount of swelling. A healthcare provider will remove the infected or inflamed areas of your colon.
