Appendicitis: Signs & Symptoms, Causes, Diagnosis

instacare

Appendicitis is an inflammation of the appendix, a small, finger-like pouch located on the lower right side of the abdomen. Though the appendix has no essential function in modern human anatomy, when it becomes infected or blocked, it can swell and cause significant pain, leading to a medical emergency if untreated.

What is the Appendix’s Role in the Body?

While the appendix’s exact purpose is unclear, some researchers believe it may play a role in the immune system, particularly in early life. However, humans can live without it, and appendectomy (removal of the appendix) does not affect long-term health.

Common Signs and Symptoms of Appendicitis

Abdominal Pain: The first sign is often a dull pain around the navel that gradually shifts to the lower right abdomen.

Loss of Appetite: Many people experience a sudden loss of appetite when appendicitis begins.

Nausea and Vomiting: This typically occurs after the onset of abdominal pain.

Sharp Pain in the Lower Right Abdomen: This pain usually intensifies over time and may worsen with movement, coughing, or sneezing.

Fever: A low-grade fever may accompany the symptoms as the infection progresses.

Constipation or Diarrhea: Changes in bowel habits, like constipation or 

Abdominal Swelling: The abdomen may appear bloated or swollen due to inflammation.

Recognizing these symptoms early can make a big difference in preventing serious complications.

Appendicitis occurs when the appendix becomes inflamed, usually due to a blockage or infection. Below are some of the common causes:

Hardened Stool: Sometimes, hardened stool (fecalith) can block the appendix, causing inflammation and infection.

Foreign Bodies: Rarely, objects or substances ingested can lodge in the appendix and block it.

Bacterial Infections: Infections from gastrointestinal bacteria can invade the appendix, leading to inflammation.

Viral Infections: Certain viral infections, such as gastrointestinal infections, can spread to the appendix and cause swelling.

Tumors: In rare cases, tumors in the abdomen can block the appendix and cause appendicitis.

Inflammatory Bowel Diseases: Conditions like Crohn’s disease may increase the risk of appendicitis.

Anyone can develop appendicitis, but certain factors increase the risk:

Age: Appendicitis is most common between the ages of 10 and 30.

Family History: If someone in your family has had appendicitis, you may be more likely to develop it.

Gender: Males are slightly more likely than females to get appendicitis.

If appendicitis is not treated promptly, it can lead to serious complications:

Ruptured Appendix: If the appendix bursts, it can spread infection throughout the abdomen (peritonitis), which is life-threatening.

Abscess Formation: Pus may collect in the appendix, creating a painful abscess.

To diagnose appendicitis, a combination of physical examinations and tests are used:

The doctor may press on your abdomen to check for tenderness, particularly in the lower right side.

Ultrasound: A non-invasive imaging test used to visualize the appendix.

CT Scan: The most reliable test to confirm appendicitis, giving a clear image of the inflamed appendix.

: These check for elevated white blood cell counts, a sign of infection.

Urine Tests: To rule out urinary tract infections or kidney stones, which may mimic the symptoms of appendicitis.

Seek medical help immediately if you experience any of the symptoms associated with appendicitis, especially severe abdominal pain, fever, or nausea. Delaying medical attention could lead to a ruptured appendix.

Laparoscopic Appendectomy: A minimally invasive surgery using small incisions to remove the appendix. It has a shorter recovery time.

Open Appendectomy: A larger incision is made to remove the appendix if complications like rupture occur.

In some mild cases, antibiotics alone may be used to treat appendicitis, but surgery is the most common treatment to prevent recurrence.

After surgery, recovery typically takes 2-4 weeks. Following your doctor’s post-operative care instructions, such as avoiding strenuous activities, is essential for healing. Pain medication and a follow-up visit are usually required.

While there’s no guaranteed way to prevent appendicitis, maintaining a healthy diet rich in fiber may reduce the risk by promoting healthy digestion. Regular exercise and staying hydrated may also contribute to overall digestive health.

1. What is the first sign of appendicitis?

The first sign is often dull pain near the navel that moves to the lower right abdomen.

2. Can appendicitis heal without surgery?

In rare cases, mild appendicitis may be treated with antibiotics, but surgery is usually necessary to prevent complications.

3. How long does it take to recover from an appendectomy?

Recovery typically takes 2-4 weeks, depending on the type of surgery and the patient’s overall health.

There’s no sure way to prevent appendicitis, but a high-fiber diet may help lower the risk.

5. What happens if appendicitis is left untreated?

Untreated appendicitis can lead to a ruptured appendix, causing life-threatening infections.
