Through layered measures, of which the least technological is the most important — hand hygiene — and the persistent difficulty is not knowing what to do but achieving consistent compliance under
By progressively loading tissue so it adapts and recovers function — and the modern approach is substantially more active and starts substantially earlier than the rest-and-wait model most people
A condition in which the skin's barrier function is impaired, allowing moisture out and irritants and allergens in, producing inflammation, itching and dryness — and understanding it as a barrier
In vitro fertilisation — eggs are collected, fertilised in a laboratory, and an embryo transferred to the uterus. It works, it works less often than most people assume, and success depends
By interrupting one of a small number of steps — preventing ovulation, preventing sperm reaching an egg, or preventing implantation — and knowing which step a method targets explains its
A screening process, a donation taking around ten minutes, and then a considerable amount of laboratory work — most of which donors never see and which explains why the appointment takes an hour for
Protect them, time it, and do not restrain them or put anything in their mouth — two interventions that people instinctively attempt and that cause harm. What to do during a convulsive seizure: Note
A small gland in the neck producing hormones that set the body's metabolic rate — effectively the pace at which everything runs — which is why thyroid problems produce such varied symptoms and are so
They share a name and almost nothing else. Osteoarthritis is a problem of the joint structure; rheumatoid arthritis is a disease of the immune system that happens to attack joints — and they are
A long-term condition in which the airways are inflamed and over-reactive, narrowing in response to triggers — and the most important thing to understand is that the two main inhaler types do
To reduce the risk of aspiration — stomach contents entering the lungs while you are unconscious — which is uncommon and can be very serious when it happens. The mechanism. Awake, you have protective
Mostly because the hair cells in the inner ear are damaged over a lifetime and do not regenerate in humans — a cumulative, largely irreversible loss that begins far earlier than most people realise.
The kidneys do far more than make urine. They are continuous chemical regulators, and dialysis replaces only part of what they do — which is why it is a treatment rather than a cure. What healthy
Through a tightly time-limited process that depends on how someone dies as much as on whether they consented — which is why donation is possible far less often than people assume. The constraint
Palliative care is treatment focused on quality of life for people with a serious illness. It is not the same as end-of-life care, and the widespread belief that it means giving up is both wrong and
By damaging cells that are dividing rapidly, which is what cancer cells do — and also what several healthy tissues do, which is where essentially all the side effects come from. The mechanism.
Through a sequence that moves from suspicion to tissue, because only examining the cells themselves gives a definitive answer — scans and blood tests can suggest, but they cannot confirm. The usual
The immune system misidentifies a harmless substance as a threat and mounts a defence against it — and the damage comes entirely from your own response, not from the substance itself. The mechanism,
A stroke is a sudden interruption of blood supply to part of the brain, and FAST is the recognition tool designed to make the most common signs memorable — because treatment is extraordinarily
They are different emergencies with different causes and different responses, and the terms are used interchangeably far more often than they should be. A heart attack is a circulation problem; a
The point at which menstruation has stopped for twelve consecutive months, marking the end of ovarian function — and most of what people describe as "the menopause" is actually perimenopause, the
They alter neurotransmitter signalling, most commonly serotonin — and the honest position is that how that produces improvement in mood is not fully understood, which is worth stating plainly because
Repeated interruption of breathing during sleep, lasting seconds at a time and occurring anywhere from a few to hundreds of times a night — and it matters because the person affected is usually
A disorder of gut-brain interaction producing abdominal pain and altered bowel habit without structural disease — and the diagnostic approach has shifted from excluding everything to positive
