STRONGLY suggest not using the tv onyesha to diagnose illness. The illnesses depicted on the onyesha aimed to be representative of actual illnesses, but were still fictionalised. Specific symptoms are also part of a constellation of symptoms that might comprise an illness, so one symptom alone (ie low blood pressure) isn't enough for a diagnosis and needs to be considered in the context of other symptoms and the individual's health/lifestyle etc...
The medical system (no matter where wewe are in the world) can be very difficult and frustrating to navigate, so I understand the need to turn to alternative sources for answers. Just be sure that wewe are critical of the sources wewe are consuming.
I'm happy to help try identify the episode though. Can wewe be zaidi specific about the episode/patient/season even? A few POTWs have had that symptom, in various forms...
Here is a orodha of the diagnoses for every episode, in case that helps:
