Fictional diseases can be a great way to add some verisimilitude to a setting while setting it apart from real life. These tables allow you to easily create something interesting and unique for your world. I wrote most of these tables while I was incredibly sick, which did help with inspiration, but I can’t recommend researching illnesses and writing about them while you’re already sick. It really isn’t a great distraction.
I recommend rolling 2-4 times on the Symptoms table to create an interesting combination. All of the symptoms are relatively grounded and should fit in just about any setting, but their severity can vary a lot. If you have a particular severity in mind, you might want to roll a couple of extra times then cut the rolls that don’t fit, or just choose the options yourself.
Whenever a table entry says ‘body part’ you can either roll on the body part table or choose a more specific body part yourself.

The Treatment table will generate a cure for your sparkly new disease. The cures it generates will be weird. They’re based on real life folk remedies, mainly the more bizarre medieval ones, so they don’t really fit in modern or sci-fi settings. It’s up to you whether the remedy you generate actually works or is just superstition.
When an entry in the Treatment table uses the word substance, roll on the Substance table. The Substance table includes plants from all around the world, so you might want to reroll if they don’t match the climate or area in your world. Also, you can occasionally generate some truly absurd treatments, like eating only ash for a month, which might warrant a reroll.
