Appendicitis is caused by both anatomical factors of the body and lifestyle dietary patterns. The appendix is a tube that is open at one end and closed at the other, communicating with the cecum. Due to its narrow and long nature, it is easy for fecal matter to block the appendix, leading to increased pressure within the tube, mucosal ischemia necrosis, and subsequently triggering inflammation. Additionally, irregular eating habits, such as binge eating, habitual drinking, and consumption of spicy food, can provoke inflammation of the appendix. Once appendicitis is diagnosed, it is mostly treated surgically. The laparoscopic appendectomy is commonly used nowadays, which is a minimally invasive treatment that allows for a faster recovery and leaves smaller scars on the body surface.

What department should I go to for appendicitis?

Appendicitis is a very common disease in general surgery, so you can visit the general surgery department at the hospital. The main symptoms of appendicitis are abdominal pain, vomiting, or fever, with the pain being quite severe in acute cases. If the appendix becomes suppurative, it can lead to the formation of a peri-appendicular abscess or appendix perforation, which then causes peritoneal irritation. Active surgical treatment should be pursued, options include traditional removal surgery or laparoscopic appendix removal. Postoperative care should be tailored to the condition of the patient, and rest is essential.

Is appendicitis contagious?

Appendicitis is an inflammation that occurs in the lumen of the appendix, including acute appendicitis and chronic appendicitis. Appendicitis is not contagious, as it is not an infectious disease, but rather a purulent inflammation. Therefore, there is no need to isolate patients with appendicitis. Appendicitis usually requires surgical removal, but it is important to note that surgery should not be performed if acute appendicitis has been present for more than 72 hours, or if an abscess has formed. The majority of surgeries are performed using laparoscopic appendectomy, a method which allows for a faster recovery post-operation.

What are the symptoms of appendicitis?

Appendicitis is an acute inflammation occurring in the lumen of the appendix. The primary symptoms include fever, nausea, vomiting, abdominal tenderness, and rebound pain. Migratory right lower abdominal pain is a common indicator used for diagnosing appendicitis. Additionally, appendicitis located posterior to the peritoneum may also present with radiating pain in the lower back. Once appendicitis is diagnosed, surgical treatment is required, except for elderly or frail individuals who cannot tolerate surgery and may opt for conservative treatment. Laparoscopic appendectomy is a commonly used surgical method, as it involves less bleeding during surgery and faster recovery afterwards. Postoperative care should be emphasized, with adjustments in diet, and an increased intake of vegetables to prevent constipation.

Postoperative diet for acute appendicitis

Postoperative diet for acute appendicitis should be taken with special attention. On the day of the surgery, no food should be consumed. After waiting for anal gas to pass, which typically occurs on the first day post-surgery, a semi-liquid diet can be chosen, consisting of easily digestible foods such as rice porridge, millet congee, and vegetable soup. From the third to the fifth day post-surgery, a normal diet can be resumed, including eating eggs and meat to supplement proteins and dietary fibers, which help the incision heal. Vegetables and fruits should also be consumed to prevent constipation. Additionally, proper care should be taken of the incision site, including regular dressing changes.

Does appendicitis hurt?

Appendicitis is generally divided into chronic and acute appendicitis. Both chronic and acute appendicitis can cause pain, which is usually severe. In cases of acute appendicitis, if the pain subsides after a while, it is actually more dangerous. It may indicate complications such as intestinal perforation or intestinal necrosis, leading to gradually diminishing pain. In such cases, timely surgical removal is necessary; otherwise, if local ulceration occurs, it can potentially affect the entire intestine. Thus, appendicitis generally causes pain, especially during the chronic phase. The pain is quite noticeable and, although generally bearable, can directly impact the quality of life.
