Appendicitis

What is Appendicitis?

Appendicitis is a medical condition that occurs when the appendix, a small pouch-like organ attached to the large intestine, becomes inflamed and swollen. The exact function of the appendix has yet to be well understood, but it is believed to play a role in the immune system. When the appendix becomes blocked or infected, it can lead to inflammation, which can be a medical emergency if not treated promptly.


Impact of Appendicitis On Anatomy and Health

Appendicitis impacts your anatomy and health in several ways:

  • Inflammation: The appendix becomes inflamed due to a blockage, which various factors, such as a small piece of stool, a foreign object, or an infection, can cause. This inflammation can lead to severe pain and discomfort in the lower right abdomen.
  • Infection: If not treated, an inflamed appendix can rupture, spilling its contents, including infectious materials, into the abdominal cavity. This can lead to a condition called peritonitis, which is a serious and potentially life-threatening infection of the abdominal lining.
  • Pain: One of the hallmark symptoms of appendicitis is abdominal pain, which usually starts around the belly button and then moves to the lower right side. This pain can be intense and may require surgical intervention to alleviate it.
  • Fever: Appendicitis can cause a fever as a response to the infection and inflammation in the body.
  • Nausea and Vomiting: Many people with appendicitis experience nausea and may vomit, as the condition affects the digestive system.


Risk Factors for Appendicitis

Appendicitis can affect people of all ages, but some individuals may be more at risk:

  • Age: It most commonly occurs in people between 10 and 30.
  • Gender: Men are slightly more likely to develop appendicitis than women.
  • Family History: If you have a family history of appendicitis, you may be at a higher risk.


Causes of Appendicitis

The exact causes of appendicitis are not always clear, but it is often associated with a blockage in the appendix. Common causes of blockage include:

  • Fecalith: This is a hard piece of stool that can block the opening of the appendix.
  • Enlarged Lymphoid Follicles: Sometimes, the lymphoid tissue in the appendix can swell and block the appendix.
  • Infection: Infections in the gastrointestinal tract can lead to inflammation in the appendix.


Symptoms of Appendicitis

Common symptoms include:

  • Abdominal Pain: The pain usually starts around the belly button and then moves to the lower right side of the abdomen. It can be sharp and severe.
  • Fever: A fever is often present, indicating an infection.
  • Nausea and Vomiting: Many people with appendicitis feel nauseous and may vomit.
  • Loss of Appetite: A sudden loss of appetite is common.
  • Constipation or Diarrhoea: Changes in bowel habits can occur.
  • Painful Urination: Some individuals may experience pain while urinating.


Types of Appendicitis

  • Acute Appendicitis: This is the most common type and refers to the sudden inflammation of the appendix. It typically requires immediate medical attention and surgery.
  • Chronic Appendicitis: This is a less common form where the symptoms are milder and may come and go over time. Diagnosis can be challenging, as the symptoms may be less severe and specific.
  • Perforated Appendicitis: The appendix can rupture or perforate when acute appendicitis is left untreated. This is a serious complication that can lead to infection and peritonitis.


Diagnosis of Appendicitis

Diagnosing appendicitis often involves a combination of the following:

  • Physical Examination: A doctor will examine the abdomen, looking for tenderness and signs of inflammation.
  • Blood Tests: Blood tests can show an elevated white blood cell count, which is a sign of infection.
  • Imaging: Imaging tests, such as ultrasound or CT scans, may be performed to visualise the appendix and confirm the diagnosis.


Treatment for Appendicitis

The standard treatment for appendicitis is surgical removal of the inflamed appendix. This procedure is called an appendectomy and can be performed using different approaches:

  • Laparoscopic Appendectomy: This minimally invasive surgery involves small incisions and using a camera and specialised instruments to remove the appendix.
  • Open Appendectomy: In some cases, an open surgery with a larger incision may be necessary, especially if there are complications or the appendix has ruptured.

In most cases, the surgery is successful, and the patient can recover fully. After surgery, antibiotics may be prescribed to prevent infection.


What if Appendicitis is Untreated?

Untreated appendicitis can lead to severe complications, including:

  • Appendix Rupture: If the inflamed appendix is not removed, it can rupture or perforate. This can release infected material into the abdominal cavity, leading to peritonitis, a life-threatening infection of the abdominal lining.
  • Abscess Formation: An untreated ruptured appendix can lead to the formation of an abscess, a pocket of pus. This may require additional drainage procedures and prolonged hospitalisation.
  • Sepsis: In severe cases, untreated appendicitis can lead to sepsis, a systemic infection that can be life-threatening.


Therefore, seeking prompt medical attention is crucial if you suspect you have appendicitis. Delaying treatment can result in more severe complications, so early intervention is key to a successful recovery.
