Appendicitis often causes fever, due to systemic infection caused by inflammation entering the bloodstream. Generally, it only causes a low fever without chills. The temperature in suppurative appendicitis does not exceed 38 degrees Celsius. High fever above 38 degrees Celsius is mostly seen in cases of appendiceal perforation or concurrent peritonitis. In addition to fever, acute appendicitis also presents with abdominal pain, tenderness and rebound pain in the abdomen, tension in the abdominal muscles, as well as nausea, vomiting, and increased frequency of bowel movements due to reflexive gastric spasms.

How to relieve pain from acute appendicitis

For rapid pain relief in acute appendicitis, one can choose antispasmodic or sedative medications. However, it is important to note that acute appendicitis often requires surgical treatment clinically. If the pain is not particularly severe, conservative medication treatment can also be chosen, using sensitive antibiotics for anti-inflammatory pain relief. If surgery involves appendectomy, laparoscopic appendectomy is generally chosen, which has less intraoperative bleeding and quicker postoperative recovery. Only after the appendix is removed can the onset of acute appendicitis be effectively controlled or the transition from acute to chronic appendicitis prevented. (Specific medications should be used under the guidance of a physician.)

What to pay attention to with appendicitis

Patients with appendicitis should pay attention to diet adjustments and regular routines, as well as choosing the correct treatment method. Diet should be lighter, consume more vegetables, ensure smooth bowel movements, eat less raw, cold, and spicy foods, rest more, and avoid excessive fatigue, especially staying up late. Additionally, pay attention to active and effective treatments. Currently, surgical treatment is the main approach, and laparoscopic appendectomy can be chosen. This surgical method involves less bleeding during the operation and a faster postoperative recovery, requiring a rest period of two weeks post-surgery.

Early symptoms of appendicitis

What are the initial symptoms of appendicitis? It is characterized by abdominal pain. The main symptom is abdominal pain that appears around the upper abdomen or navel, and some patients may also experience nausea and vomiting. Generally, two to three hours later, the abdominal pain gradually shifts to the lower right abdomen, which we clinically refer to as migratory right lower abdominal pain. This symptom accounts for about 80% of clinical cases, while some patients present directly with pain in the lower right abdomen, without transitional abdominal pain. Therefore, the primary symptom of appendicitis is abdominal pain, as described in these two scenarios. However, physical examination is also very important, typically revealing localized fixed tenderness in the lower right abdomen as the main clinical manifestation.

Can appendicitis cause vomiting?

Some patients with appendicitis may experience symptoms such as nausea and vomiting. This is because the appendix is located in the lower right abdomen near the ileocecal area, and the appendix cavity is connected to the cecum. The appendix is an independent organ of the human digestive tract. When inflamed, the inflammation can easily irritate the surrounding intestines, causing intestinal spasms and contractions, leading to nausea and vomiting. A typical manifestation of appendicitis is referred pain in the lower right abdomen. Once appendicitis is diagnosed, it is advisable to promptly start anti-inflammatory treatment and, if necessary, proceed with surgical treatment. Appendicitis can range from acute simple appendicitis, which responds well to conservative anti-inflammatory treatment, to acute suppurative or even perforated appendicitis. In these severe cases, it is recommended to perform surgery as soon as possible to remove the appendix and clear the inflammatory secretions, alongside anti-inflammatory treatment.

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.
