    You probably think the appendix is a useless organ left over from our evolutionary past, but it turns out it may be doing something important after all.

      most appendicitis cases are uncomplicated, which means the organ hasn't ruptured, so they can be treated with antibiotics. Only when the appendix looks like it may burst immediately is an surgery necessary.
      also, according to several studies, antibiotic prophylaxis should be administered before every appendectomy.
      feel free to lookup nih/pubmed for more.

    Then wouldn't it be easy to compare immune system in people before/after appendix removal? Seems sketchy to bump into some immune system benefits just now..

    I hypothesized that it had something to do with the immune system and our digestive system over 25 years ago when I noticed that people that I knew without theirs tended to have longer and more severe bouts of gastroenteritis (stomach flu).

    So having an appendix is like having an extra safety against burglars that makes you more likely to get murdered instead.

    Actually this kind of makes sense. My son and I still have our appendices and we are in relatively good health - gut wise. We seldom get the runs.
    My husband on the other hand, had his appendix removed many years ago and he has had numerous belly upsets, cramps and gut issues ever since....
    I realise this is only anecdotal, but it does make sense to me. Thanks Scishow.

    Acute appendicitis can kill you. Every minute counts. It killed my grandfather. Please don't put off seeing the dr or going to the ER. It's great that the appendicitis may actually serve a purpose, but don't ignore any symptoms. It's better to be appendix-less than very sick or dead. 😢

    Instead of being spelled with the standard "apendiks", it was awarded ultra-rare & highly coveted letter X license which bundles two consonants into a single character.

    Most of what we used to call vestigial organs are not actually useless. It is just our arrogance which make us think we know everything so when we don't know the function of an organ we are tend to think it is just a useless leftover.

    First tonsils, now the appendix. What other commonly removed body part is going to end up being an important immune system player? At this point I wouldn't be surprised if wisdom teeth turned out to be more important than we thought.

      Tonsils do have a purpose the help keep germs out of your throat and they hold a large amount of white blood cells witch helps fight infection when your tonsills are fighting an infection that's why you get a "sore throat" and in 1 out of 5 patients that get there tonsils removed had issues so your tonsils are pretty important and dont call me out and say I'm wrong because I just did research

    I have a friend who can't take antibiotics without getting the worst case of the runs after having his removed. So it's probably for gut bacteria.

    I still remember what pain it gave me. I was having severe abdominal pain for days with fever and i was getting paler by the day. Ofc i ended in the hospital on the end and i remember the moment it bursted there. It was like a fist squeezing my guts. Squeezing and twisting it with this very sharp pain that almost made me pass out on the spot. The pain made me scream for my mother out of sheer panic.
    That continued until the nurse gave me a shot that made all the lights have rainbow halos around them and i passed out. 😂🌈
    Doctors and nurses told me that if i had delaid with couple hours it would have been unlikely for me to survive the surgery. Life is absurd.. 😁 good ridance though!
