Appendicitis is an inflammation of the appendix. It’s a medical emergency that almost always requires surgery as soon as possible to remove the appendix. Luckily, you can live just fine without it.

This 3 1/2-inch-long tube of tissue extends from your large intestine on the lower right side of your body. The appendix has specialized tissue that can make antibodies, but no one is completely sure what its function is.

In the U.S., 1 in 20 people will get appendicitis at some point in their lives. Although it can strike at any age, appendicitis is rare in children younger than 2. It’s most likely to affect people between the ages of 10 and 30.

Appendicitis happens when the appendix gets blocked, often by poop, a foreign body (something inside you that isn’t supposed to be there), or cancer. Blockage may also result from infection, since the appendix can swell in response to any infection in the body.

The classic symptoms of appendicitis include:

• Pain in your lower right belly or pain near your navel that moves lower. This is usually the first sign.
• Loss of appetite
• Nausea and vomiting soon after belly pain begins
• Swollen belly
• Fever of 99-102 F
• Can’t pass gas

Other less common symptoms of appendicitis include:

• Dull or sharp pain anywhere in your upper or lower belly, back, or rear end
• Painful or difficult peeing
• Vomiting before your belly pain starts
• Severe cramps
• Constipation or diarrhea with gas

If you have any of these symptoms, see a doctor right away. Timely diagnosis and treatment are important. Don’t eat, drink, or use any pain remedies, antacids, laxatives, or heating pads.

Diagnosing appendicitis can be tricky. Symptoms are often unclear or similar to those of other illnesses, including gallbladder problems, bladder or urinary tract infection, Crohn’s disease, gastritis, kidney stones, intestinal infection, and ovary problems.

These tests can help diagnose appendicitis:

• Examination of your abdomen to look for inflammation
• Urine (pee) test to rule out a urinary tract infection
• Rectal exam
• Blood test to see whether your body is fighting an infection
• CT scans
• Ultrasound

Appendicitis is almost always treated as an emergency. Surgery to remove the appendix, which is called an appendectomy, is the standard treatment for almost all cases of appendicitis.

Generally, if your doctor suspects that you have appendicitis, they will quickly remove it to avoid a rupture. If you have an abscess, you may get two procedures: one to drain the abscess of pus and fluid, and a later one to take out the appendix. But some research shows that treating acute appendicitis with antibiotics may help you avoid surgery.

Before your appendix is taken out, you’ll take antibiotics to fight infection. You’ll usually get general anesthesia, meaning you’ll be asleep for the procedure. The doctor removes your appendix through a 4-inch-long cut or with a device called a laparoscope (a thin telescope-like tool that lets them see inside your belly). This procedure is called laparoscopy. If you have peritonitis, the surgeon will also clean out your belly and drain the pus.

You can get up and move around within 12 hours after surgery. You should be able to go back to your normal routine in 2 to 3 weeks. If you had a laparoscopy, recovery is faster.

After an appendectomy, call your doctor if you have:

• Uncontrolled vomiting
• Increased belly pain
• Dizziness/feelings of faintness
• Blood in your vomit or pee
• Increased pain and redness where your doctor cut into your belly
• Fever
• Pus in the wound

Left untreated, an inflamed appendix will burst, spilling bacteria and debris into the abdominal cavity, the central part of your body that holds your liver, stomach, and intestines. This can lead to peritonitis, a serious inflammation of the abdominal cavity’s lining (the peritoneum). It can be deadly unless it is treated quickly with strong antibiotics and surgery to remove the pus.

Sometimes, an abscess forms outside an inflamed appendix. Scar tissue then “walls off” the appendix from the rest of your organs. This keeps the infection from spreading. But an abscessed appendix can tear and lead to peritonitis.

There’s no way to prevent appendicitis. But it may be less common in people who eat foods high in fiber, such as fresh fruits and vegetables.

What is acute appendicitis?

Acute appendicitis is a non-cancerous disease caused by: acute inflammation in the appendix a small finger-shaped organ that connects to the large intestine (colon) through a small opening. For most people, the appendix is ​​located in the lower right side of the abdomen, just above the pelvic bone. Acute appendicitis can occur in any age group but most commonly affects teenagers and young adults.

What causes acute appendicitis?

In acute appendicitis, the small opening of the appendix is ​​blocked, often by a piece of overcooked food called feces. When the hole is blocked, bacteria that normally live in the colon fills up the appendix. Your immune system responds by sending specialized immune cells called neutrophils to surround and destroy the bacteria. The combination of bacteria and neutrophils leads to the formation of pus.

What are the symptoms of acute appendicitis?

Patients with acute appendicitis usually experience gradual, constant pain that starts near the navel and progresses to the right lower abdomen. Other possible symptoms may include nausea, vomiting, loss of appetite, diarrhea, and fever.

How is acute appendicitis diagnosed?

The diagnosis is made after the appendix is ​​surgically removed and sent to a pathologist for examination under a microscope. If your doctor suspects acute appendicitis, they will order a blood test and x-ray imaging, such as an ultrasound or CT scan. Your blood test usually shows a large number of immune cells called white blood cells (WBCs). An ultrasound or CT scan usually shows an enlarged appendix. Acute appendicitis is most often treated by removing the appendix.

What does acute appendicitis look like under a microscope?

When your pathologist examines your appendix under a microscope, he will look for specialized immune cells called neutrophils in the wall of your appendix. These neutrophils often combine with bacteria to form an abscess (pus). Neutrophils can also be seen on the outer surface of the appendix. Pathologists describe it as periappendicitis.

Observations and tips of this article we have prepared based on the experience of the team, the inflammation observed in acute appendicitis begins on the inside of the appendix, but spreads rapidly, affecting the wall and even the outer part of the appendix. The appendix can also swell, which blocks blood from getting in and out of the appendix. When this happens, parts of the appendix may begin to die due to a process called necrosis.

Acute appendicitis. This low magnification microscopic image shows an appendix with signs of acute appendicitis.

What does perforated appendicitis mean?

If left untreated, a hole or perforation may form in the appendix, and material inside the appendix may enter the abdominal cavity. This release can cause an abscess to form around the appendix.

What does periappendicitis mean?

Periappendicitis refers to inflammation on the outer surface of the appendix. Periappendicitis is a very common finding in acute appendicitis.
