The main causes of appendicitis are the narrowing of the appendix lumen and the subsequent blockage of the appendix lumen. Bacterial infection can directly cause acute inflammation. Additionally, poor dietary habits in daily life can also trigger appendicitis. These include overeating and binge drinking, engaging in strenuous exercise right after eating, consuming strong tea, coffee, or spirits, neglecting rest, and excessive fatigue. Therefore, for the prevention of appendicitis, it is mainly important to develop regular lifestyle and eating habits, with meals at fixed times and in measured amounts, and consuming more vegetables to ensure the smooth functioning of the gastrointestinal tract.
