Appendicitis is the inflammation of the appendix, a finger-shaped pouch that protrudes from your colon in the lower right side of your abdomen. When you were a young child, your appendix was a functioning part of your immune system, helping your body fight off illnesses. As you age, your appendix stops doing this, and the other parts of your body continue to help fight infections.
Appendicitis causes pain in the lower right abdomen. However, in most people, the pain starts around the belly button and then moves towards the lower right abdomen. As the inflammation worsens, appendicitis pain typically increases and eventually becomes severe.
While appendicitis can develop in anyone, it is most commonly seen in individuals between the ages of 10 and 30. The standard treatment for appendicitis is surgical removal of the appendix.
What are the Symptoms of Appendicitis?
The symptoms of appendicitis can include:
- Sudden pain starting in the lower right side of the abdomen
- Sudden pain starting around your belly button and often moving towards your lower right abdomen
- Pain worsening when you cough, walk, or make other jarring movements
- Nausea and vomiting
- Loss of appetite
- Low-grade fever that worsens as the illness progresses
- Constipation or diarrhea
- Abdominal bloating
The location of your pain can vary depending on your age and the location of your appendix.
What Causes Appendicitis?
A possible cause of appendicitis is a blockage that results in infection in the lining of the appendix. Bacteria rapidly multiply, leading to inflammation, swelling, and the filling of the appendix with pus. If not promptly treated, the appendix can rupture.
What are the Complications of Appendicitis?
Appendicitis can lead to serious complications, including:
- A ruptured appendix: A rupture spreads the infection into your abdomen (peritonitis). This life-threatening condition requires immediate surgery to remove the appendix and clean the abdominal cavity.
- Abscess in the abdomen: If the appendix bursts, an abscess, which is a pocket of infection, can develop. In most cases, a surgeon will place a tube through your abdominal wall to drain the abscess. The tube is left in place for about two weeks, and you’re given antibiotics to clear the infection. Once the infection is cleared, you’ll have surgery to remove the appendix. In some cases, the abscess is drained, and the appendix is removed immediately.
How is Appendicitis Diagnosed?
Your healthcare provider will ask about your medical history and perform a physical examination. They may also request the following tests:
Blood tests: To check for signs of infection, such as a high white blood cell count.
Urine tests: To check for a urinary tract infection.
You may also have some imaging tests, including:
- Abdominal ultrasound: Allows the doctor to see your internal organs in action and check how blood flows through different blood vessels.
- CT scan: Shows detailed images of any part of your body, such as bones, muscles, fats, and organs.
- MRI: Sometimes used instead of a CT scan, especially in pregnant women, to diagnose appendicitis.
What is the Treatment for Appendicitis?
Appendicitis is almost always treated as an emergency. The standard treatment for almost all cases of appendicitis is surgical removal of the appendix, called an appendectomy.
In general, if your doctor suspects appendicitis, they.
What is the treatment for Appendicitis?
Appendicitis is almost always treated as an emergency. The standard treatment for almost all cases of appendicitis is surgical removal of the appendix, called an appendectomy.
In general, if your doctor suspects appendicitis, they will quickly remove it to prevent rupture. If you have an abscess, you may undergo two procedures: one to drain the abscess and fluid, and another to remove the appendix. However, some research suggests that acute appendicitis can be treated with antibiotics to help avoid surgery.
Surgical Removal of the Appendix (Appendectomy)
An appendectomy can be performed as an open surgery using an abdominal incision, typically about 2 to 4 inches (5 to 10 centimeters) long (laparotomy). Alternatively, it can be done through several small abdominal incisions (laparoscopic surgery). During a laparoscopic appendectomy, the surgeon inserts specialized surgical instruments and a video camera into your abdomen to remove the appendix.
In general, laparoscopic surgery allows for faster recovery and healing with less pain and scarring. It may be better for older adults and individuals with obesity.
However, laparoscopic surgery is not suitable for everyone. If your appendix has ruptured and the infection has spread beyond the appendix or if you have an abscess, you may need an open appendectomy, which allows your surgeon to clean the abdominal cavity.
After your appendectomy, you will spend one or two days in the hospital.
Life After Appendicitis Treatment
To aid in your body’s healing process:
- Initially, avoid strenuous activities. If your appendectomy was done laparoscopically, limit your activity for three to five days. If you had an open appendectomy, limit your activity for 10 to 14 days. Always ask your doctor about activity restrictions and when you can resume normal activities after surgery.
- Support your abdomen when coughing. Place a pillow against your abdomen and apply pressure to reduce pain before coughing, laughing, or moving.
- Call your doctor if your pain medication isn’t helping. Being in pain puts extra stress on your body and slows down the healing process. If you still have pain despite your pain medication, contact your doctor.
- Get up and move when you’re ready. Start slowly and gradually increase your activity as you feel better. Begin with short walks.
- Rest when you’re tired. As your body heals, you may notice feeling sleepier than usual. Be calm and rest as much as you need.
- Discuss returning to work or school with your doctor. When you feel well enough, you can return to work. Children can return to school within a week or less after surgery. They should wait two to four weeks before resuming strenuous activities like physical education classes or sports.
When Should You See a Doctor?
Make an appointment with a doctor if you or your child have concerning signs or symptoms. Severe abdominal pain requires immediate medical intervention.
