hypersensitivity

Definition

An exaggerated or inappropriate immune response to substances that are typically harmless, manifesting as allergies, autoimmune reactions, or in modern parlance, being unable to tolerate basically anything. In immunology, it's classified into four types ranging from immediate allergic reactions to delayed autoimmune disasters. It's your body's overachieving defense system attacking peanuts like they're invading armies.

Example Usage

Her hypersensitivity to latex meant the hospital had to use special gloves during surgery, because adding anaphylaxis to the procedure would be inconvenient for everyone.

hyperplasia

When your cells get a little too enthusiastic about multiplying and create more of themselves than necessary, making tissues or organs larger through sheer cellular overachievement. Unlike hypertrophy (where cells just get bigger), hyperplasia is about quantity over quality—your body cranking out extra cells like a factory that lost the memo about production limits. It's not always cancer, but it's definitely something your doctor wants to keep an eye on.

adenoid

Those annoying lymphatic tissue masses lurking at the back of your throat that exist solely to swell up and make breathing difficult during childhood. They're like the body's overenthusiastic security guards, getting inflamed at every passing germ and making you sound like you have a permanent cold. Surgeons love removing them almost as much as tonsils.

incidence

The number of new cases of a disease occurring in a population during a specific time period—epidemiology's way of tracking whether we should panic or just be mildly concerned. Not to be confused with prevalence, which epidemiologists will correct you about smugly.

Dosage

The specific amount of medication you are supposed to take, which exists on a spectrum between "not enough to do anything" and "you will see colors that do not exist." Getting it right is the pharmacological equivalent of Goldilocks trying porridge.

Rounds

The daily ritual where a herd of doctors and medical students parade through the hospital, stopping at each patient's bed to discuss them as if they are not right there listening to every terrifying word. The medical equivalent of a walking meeting.

exogenous

Medical and scientific jargon for "it came from outside," used when whatever is affecting you didn't originate from within your own body. It's the fancy way of saying the problem is external rather than your body just randomly deciding to malfunction on its own. Think infections from bacteria, reactions to medications, or basically anything your body didn't cook up internally.
