What are the symptoms and manifestations of acute appendicitis?
Symptoms of Acute Appendicitis
The manifestation of acute appendicitis primarily encompasses abdominal pain, gastrointestinal symptoms, fever, tenderness and rebound tenderness, as well as abdominal muscle rigidity. A detailed analysis is as follows:
Abdominal Pain
This is the most typical and common symptom. Initially, the pain typically arises in the upper abdomen or around the umbilicus, with an unfixed location and a dull or distending sensation. After a few hours, the pain shifts and localizes to the right lower abdomen, becoming persistent and gradually intensifying.
Gastrointestinal Symptoms
Symptoms such as nausea and vomiting may occur, with vomitus consisting mainly of gastric contents. Some patients may also experience anorexia, abdominal distension, and diarrhea.
Fever
Initially, the body temperature is usually normal. However, as the condition progresses, fever may develop, with the temperature rising to approximately 38°C. In cases where appendiceal perforation leads to peritonitis, the fever may be higher.
Tenderness and Rebound Tenderness
There is significant tenderness at McBurney's point (the intersection of the mid-outer 1/3 line connecting the umbilicus and the anterior superior iliac spine) in the right lower abdomen. When pressure is applied and released, the pain intensifies, known as rebound tenderness.
Abdominal Muscle Rigidity
In cases of appendiceal suppuration, gangrene, or perforation, abdominal muscle rigidity may manifest, characterized by hardened abdominal muscles.
Not all these symptoms necessarily occur simultaneously, and their manifestation may vary in degree due to individual differences and the severity of the condition. Upon the appearance of suspected symptoms of acute appendicitis, prompt medical attention should be sought for early diagnosis and treatment.
