I lowkey think lil bro has either appendicitis, internal bleeding of the GI tract due to ulcers, masked viscus perforation of any of his abdominal organs (most likely appendix or his bowel), or even pancreatitis. Any of these conditions can be exacerbated by his routine medication, which I think are anxiety, depression, and/or insomnia meds. Those medications fall under a greater class of drugs called SSRI/SNRIs that basically fuck with your platelets' ability to form clots (part of blood) and that put you at a much greater risk for internal bleeding. If your platelets are compromised because of a medication, it can cause the holes in your intestines and blood vessels to not get patched up and so they get bigger and then you're fucked. All of these will also cause low hemoglobin count and inflammatory marker hits because they can all induce infection and basically contents that are supposed to be contained are getting exposed to parts of the body that shouldnt normally happen.
My top guess is a peptic ulcer that was exacerbated by his medication because they didn't immediately rush Dohu into surgery. If it was acute appendicitis, they usually have the patient undergo surgery right away. Instead, they're admitting him for a few days to run tests, which a peptic ulcer can be diagnosed in those few days and it's harder to catch right away. Appendicitis has like very distinct symptoms that weren't mentioned, but it's not off my list completely. Just wish we knew what kind of meds he was on tho so I could come up with a better guess.
yeah febrile/sick > sudden onset abdominal pain makes me think appe, PUD +/- perforation, etc. also manhwa in general seem to like PUD & gastritis XD tbh i wonder if it's bc of the high prevalence of gastric cancers in east asia. so maybe only other thing i was thinking was mono + trauma > spleen rupture, but he's chilling with stable vitals without intervention. he's a smoker, but no connective tissue disorder, so maybe in 10 years i'd be thinking more vascular stuff--AAA, etc. and his only lab findings are anemia and "inflammatory markers". since they made the comparison of "for his age", that made me think they're not talking about CBC/diff. but if someone was febrile and then passed out, i'm not getting an ESR/CRP/etc...
Yes, I was thinking same cuz idk how many times I commented or read comments on manhwas of all these valid serious theories and the author just does a 180 and makes it be something unsientific like "growing pains" or "he had a fever and fainted bc of broken heart" or some shit
I fucking loved reading all these medical theories tho, thank you OP!
If the author pulls some bulshit I'll just use one of your diagnoses and use it as headcanon.
As someone who just suffered from this for a month, got tests done with inflammatory markers positive, got an emergency endoscopy+ colonoscopy to ve diagnosed with pangastritis and erythematous sigmoid colon, and the start of a peptic ulcer with low hemoglobin, yes that checks out. The moment he held his stomach and got nauseous/dizzy i got ptsd fr. I'm still trying to heal and taking meds for all that
