Appendicitis

Your belly can sometimes hurt.

A small part inside can get swollen. This is called appendicitis. It often happens when something blocks the part.

This block can make the part swell up. It may cause pain in your lower belly. You might also feel sick or have a fever. A doctor can use special pictures to help.

They can use a tool called an ultrasound. A doctor can also help you feel better with surgery.

Your belly can sometimes hurt.

This pain can be caused by appendicitis. This is when the appendix gets swollen. The appendix is a small part in your gut.

Most cases start with a blockage. A tiny, hard stone of waste can get stuck. We call this a fecalith. Other things like germs or tumors can also cause a block. When the appendix is blocked, it fills with mucus. This makes the pressure go up inside. The pressure stops blood from flowing well. This can cause the tissue to die. If the appendix bursts, it lets bacteria out into your belly. This is very serious.

Many people feel pain in the lower right side. You might also feel sick or have a fever. Doctors use tests to find the problem. They may use an ultrasound. They might also use a CT scan. A CT scan is a special picture that is very accurate.

To fix it, doctors often do surgery. They remove the appendix to keep you safe.

Appendicitis is a common reason for sudden belly pain. It happens when the appendix becomes swollen and inflamed. The appendix is a small part of your digestive system.

This condition is a significant medical issue for many people. If it is not treated, the appendix can burst. This is a very serious event for the body.

Doctors must act quickly to help the person feel better.

The problem usually starts with a blockage in the appendix. A tiny, hard stone made of waste can get stuck. This is called a fecalith.

Other things like tumors or germs can also cause a block. When the appendix is blocked, it fills with mucus. This causes the pressure inside to go up. The high pressure stops blood from flowing through the area. Eventually, the tissue can become damaged or even die.

Doctors look for specific signs to find appendicitis. Many people feel pain near their belly button first. After a few hours, the pain often moves to the lower right side. People might also feel sick to their stomach or have a fever. A doctor might check for pain when a person coughs. This is called Dunphy's sign. They may also feel the belly to see if it is sensitive. This helps them understand how much inflammation is present.

To be sure, doctors use special imaging tests. An ultrasound is often used for children or pregnant women.

This is because it does not use radiation. A CT scan is another common test.

A CT scan is very accurate at finding the problem. Doctors also check blood to look for signs of infection. They look for a high white blood cell count. This shows the body is fighting something.

The most common way to fix appendicitis is surgery. A surgeon removes the inflamed appendix to keep the person safe. They can do this through a small cut called an open incision. They can also use a laparoscopy. This method uses tiny cuts and a small camera. In 2015, there were about 11.6 million cases reported worldwide. This led to around 50,100 deaths. In the United States, over 300,000 people have this surgery every year.

Appendicitis is the inflammation of the appendix, a small part of the digestive system.

It is one of the most common causes of sudden abdominal pain worldwide. This condition is a significant medical concern because it can lead to serious complications. If the inflammation is not treated, the appendix can rupture. A rupture releases bacteria into the abdominal cavity. This can cause peritonitis, which is widespread inflammation of the inner abdominal lining. It may also lead to sepsis, a very serious body-wide response to infection.

The process of appendicitis usually begins with a primary obstruction. This blockage occurs in the hollow portion, or lumen, of the appendix. The most common cause is a fecalith, which is a calcified stone made of feces.

Other causes include intestinal parasites, tumors, or inflamed lymphoid tissue from a viral infection. Once the appendix is blocked, it continues to produce mucus. This buildup increases the pressure within the appendix walls. This high pressure causes thrombosis, which is the blocking of small blood vessels. It also stops the flow of lymphatic fluid. As blood flow decreases, the tissue becomes ischemic, meaning it lacks oxygen. Eventually, the tissue becomes necrotic, or dies. Bacteria can then leak through the dying walls, leading to suppuration, or the formation of pus.

Symptoms of appendicitis can be categorized as typical or atypical. Typical cases often follow a specific pattern of pain. The pain may start as a dull ache around the navel. After several hours, the pain often migrates to the right lower quadrant. This is known as Kocher's sign. As the appendix swells, it irritates the nearby abdominal wall. This causes the area to become very sensitive to pressure, a process called palpation. Other common symptoms include nausea, vomiting, fever, and anorexia, which is a loss of appetite. Interestingly, about 40% of people do not experience these typical symptoms. Atypical cases might present with pain in the right lower quadrant from the very beginning.

Doctors use several physical signs to help identify the condition during an exam. One example is Dunphy's sign, where coughing causes sharp pain in the right lower quadrant. Another is the Psoas sign, where pain occurs when the person moves their right hip. Doctors also look for Blumberg's sign, which is pain felt when deep pressure on the abdomen is suddenly released. In some cases, the appendix may be retrocecal, meaning it sits behind the cecum. This position can make the appendix "silent" because the cecum protects it from pressure. If the appendix is located in the pelvis, a doctor might use a digital rectal examination to find tenderness. There are many such specialized signs used to detect the specific location of the inflammation.

To confirm a diagnosis, medical professionals use laboratory tests and imaging. A complete blood count (CBC) is a standard test to check for infection. Doctors look for an elevated white blood cell count, which indicates the body is fighting inflammation. The neutrophil-lymphocyte ratio can also be a very accurate indicator in children. For imaging, doctors often use ultrasound or computed tomography (CT) scans.

A CT scan is generally more accurate for detecting acute appendicitis. However, ultrasound is often the first choice for children and pregnant women. This is to avoid the risks of radiation exposure associated with CT scans. Ultrasound is also helpful for identifying other issues, such as ovarian pathology in females.

Treatment for acute appendicitis almost always involves surgery to remove the appendix. This procedure is called an appendectomy. Surgeons can perform an open surgery, known as a laparotomy, using a larger incision.

Alternatively, they may use laparoscopy, which is a minimally invasive technique. This method uses small incisions and a tiny camera to perform the removal. While antibiotics may work for some non-ruptured cases, surgery is the standard to prevent death or complications. Statistics show that 31% of people treated with antibiotics for appendicitis will still need surgery within one year.

Appendicitis is a major global health issue with significant numbers. In 2015, approximately 11.6 million cases were reported worldwide. These cases resulted in about 50,100 deaths globally. In the United States, more than 300,000 people undergo an appendectomy every year. Research suggests a link between diet and the frequency of this condition. A transition to a Western diet that is lower in dietary fiber may be a factor. Higher fiber intake is thought to reduce the transit time of waste through the colon. This may help prevent the formation of the fecaliths that cause blockages.
