Appendicitis

What is appendicitis?

Appendicitis refers to inflammation of the appendix, a tube-shaped organ located in the lower right abdomen that connects to the large intestine. For many people, sudden, severe pain in the lower right abdomen is often a warning sign of appendicitis. Although the appendix does not serve a vital function in the human body and its removal does not have a negative impact on long-term health, timely specialist diagnosis and intervention are key to preventing complications and ensuring a swift return to daily life.

Learn about common causes of appendicitis

The primary cause of appendicitis is a blockage of the internal lumen of the appendix, leading to the proliferation of bacteria in a confined space and triggering acute inflammation, swelling, and even abscess formation. Common causes of appendicitis include:

Fecal impaction: The most common cause, where hardened fecal matter in the digestive tract blocks the opening of the appendix

Swollen lymph nodes: When the body is infected with a virus or bacteria (such as gastroenteritis), the lymphatic tissue surrounding the intestines may swell, compressing and blocking the appendix

Foreign objects or tumors: In rare cases, undigested food particles or, in extremely rare instances, tumors in the appendix may also cause blockages

Signs and symptoms of appendicitis

The most common symptom of appendicitis is sudden abdominal pain. Unlike general gastroenteritis, this pain typically has the following characteristics:

Wandering pain: The pain often begins in the stomach or around the navel and gradually shifts to the lower right abdomen within a few hours1.

Progressive worsening: Unlike intermittent gastrointestinal cramps, the pain of appendicitis usually intensifies over time and becomes more pronounced when coughing, walking, or pressing on the lower right abdomen.

In addition to pain, patients may also experience the following symptoms: nausea, fever, loss of appetite, diarrhea, or constipation.

Specialist advise: If you experience the above symptoms of acute appendicitis, seek medical attention immediately. Delayed diagnosis may increase the risk of appendiceal rupture, which can lead to serious complications such as peritonitis. Early evaluation by a specialist can significantly improve treatment safety and speed up recovery.

Accurate Diagnosis of Appendicitis

The symptoms of appendicitis may resemble those of kidney stones, pelvic inflammatory disease, or diverticular disease. To accurately diagnose appendicitis, Tamarind Specialists Centre will arrange the following further tests based on your specific condition:

  • Abdominal and Pelvic Ultrasound: A non-invasive test that quickly assesses whether the appendix is swollen or if there is fluid accumulation around it.

  • Computed Tomography (CT) Scan: Provides high-resolution cross-sectional images of the abdomen and is currently an extremely accurate tool for diagnosing acute appendicitis and its complications.

  • Laparoscopy: Helps assess the extent of inflammation within the body and rule out infections in other systems.

Treatment Options and Personalized Care for Appendicitis

Although a very small number of mild, early-stage appendicitis cases may improve with a course of antibiotics, in most cases, surgical removal of the inflamed appendix (appendectomy) remains the most common and effective treatment method2.

Advantages of Minimally Invasive Surgery

Colorectal surgeons primarily utilize laparoscopic minimally invasive techniques. A laparoscope and other surgical instruments are inserted through small incisions in the abdomen to perform internal surgery. This approach not only effectively removes the affected area but also offers significant benefits to patients, including significantly smaller incisions, reduced postoperative pain, shorter hospital stays and recovery times, and a lower risk of wound infection.

Walking Beside You from Treatment to Recovery

The surgical process can often be unsettling for patients. At Tamarind Specialists, we uphold a “patient-centric” philosophy. From preoperative explanations and the surgery itself to postoperative wound care, our medical team will provide clear information and support throughout the entire process, accompanying you as you rest with peace of mind and smoothly return to your daily life.

Frequently Asked Questions About Appendicitis

Besides severe pain in the lower right abdomen, what other symptoms of appendicitis are often overlooked?
Apart from the typical pain in the lower right abdomen, the early symptoms of appendicitis often resemble those of common gastroenteritis, such as nausea, loss of appetite, fever, and even diarrhea or constipation. If these symptoms are accompanied by increased pain when pressing on the lower right abdomen, coughing, or moving around, you should seek medical attention immediately to prevent delays that could lead to serious complications.
What causes appendicitis? Can it be prevented in daily life?
Appendicitis is primarily caused by a blockage in the appendix. Common causes include fecal impaction, swollen lymph nodes (such as those affected by gastroenteritis), or, more rarely, blockages caused by foreign objects or tumors. Since the onset is often related to sudden infections or anatomical factors, there is currently no definitive preventive method in medicine. However, maintaining a high-fiber diet and good bowel habits can help reduce the risk of fecal impaction.
What are the consequences or complications if appendicitis is suspected but medical attention is delayed?
If acute appendicitis is suspected, medical attention must be sought immediately. Delaying diagnosis and treatment increases the risk of appendiceal rupture, which can lead to serious complications such as peritonitis. Early evaluation and management by a doctor can effectively prevent the condition from worsening, ensure safe treatment, and speed up recovery.
Once appendicitis is diagnosed, is it necessary to undergo an appendectomy immediately?
Once appendicitis is diagnosed, doctors generally recommend immediate surgical removal of the appendix, which is currently the most common and effective treatment option. Delaying treatment may lead to rupture of the inflamed appendix, triggering life-threatening complications such as peritonitis. Although in a very small number of mild, early-stage cases, the condition can be controlled with a course of antibiotics alone, there remains a risk of recurrence in the future.
After undergoing laparoscopic appendectomy, how long does it typically take to resume normal daily activities and diet?
Laparoscopic appendectomy involves small incisions and results in relatively less postoperative pain. Most patients are discharged after one to two days of observation in the hospital. Initially after discharge, the diet should consist mainly of light, liquid foods. Patients can usually gradually resume a normal diet and daily activities within one to two weeks. Actual recovery progress varies from person to person, and the medical team will provide appropriate guidance based on the patient’s postoperative condition.
Does removing the appendix have any long-term effects on digestive function or immunity?
Removing the appendix does not have any long-term negative effects on the body. Although the appendix is connected to the large intestine, it does not play a significant role in digestion or immunity within the human body. After recovery from surgery, the patient’s gastrointestinal digestion, bowel habits, and overall immunity will function normally and will not deteriorate due to the absence of the appendix. Therefore, timely removal of an inflamed appendix is a safe treatment option.
