The Appendix: More Than Just a Useless Organ

Contrary to popular belief, the appendix serves important functions that can benefit our health. Research has shown that the appendix supports the immune system and helps fight off invading pathogens in the gut. It also acts as a safe house for beneficial gut bacteria during gastrointestinal distress, allowing the good bacteria to re-colonize the gut after a diarrheal episode. The distribution of appendices across mammalian evolution suggests that it has evolved multiple times, indicating its adaptive function. While the causes of appendicitis are still not fully understood, factors such as low fiber content in the diet leading to blockages in the appendix or an overreacting immune system due to excessive sanitization have been proposed. However, advancements in antibiotics and alternative treatments may offer potential alternatives to emergency surgery in the future.
