Because the evidence changed substantially, and the old model — rest, scan, find the damage, fix it — turned out to make outcomes worse for the great majority of cases. What is now understood: Most
A condition in which bones lose density and structural quality, becoming fragile enough to break from a fall or force that would not normally cause a fracture — and its defining feature is that it is
Change itself is the signal — a mole that is different from how it was, or different from your other moles, matters more than any single feature in isolation. The ABCDE checklist, which is the
SPF measures protection against UVB only — the radiation that causes sunburn — and the number is a ratio rather than a percentage or a time, which is the source of almost every misunderstanding about
The perception of sound with no external source — ringing, buzzing, hissing or humming — and the most useful thing to understand is that it is generated by the brain rather than the ear, which
Far more than whether you need glasses — a sight test is also a health examination, and it detects conditions with no symptoms at a stage where treatment still works. What is actually checked: Visual
Delirium is an acute, fluctuating disturbance of attention and awareness, usually caused by an underlying physical problem — and distinguishing it from dementia matters enormously, because delirium
One substance changing how another behaves in the body — either how much of it reaches the bloodstream and for how long, or what effect it has once there. Most interactions are theoretical or minor;
They are structured, time-limited treatments with evidence behind them, not simply conversation — and the differences between them matter, because they suit different problems. The main types:
Anaemia is too little haemoglobin — the protein in red blood cells that carries oxygen — so tissues receive less oxygen than they need. It is a finding, not a diagnosis, and the important question is
Not as a single queue. There are several different waits measured in different ways, and most public confusion comes from treating one number as though it described everything. The main pathways:
Mostly by listening — the history gives the diagnosis in a large majority of cases — followed by examination and, only then, tests to confirm or exclude. The popular image of diagnosis as a puzzle
Cholesterol is a lipid the body needs — a component of every cell membrane and the raw material for steroid hormones, vitamin D and bile acids. Your body makes most of it. The problem is not its
Two different diseases that share a symptom — raised blood glucose — and have almost nothing else in common. Conflating them causes real harm, including to people with type 1 who are told their
Because pain is not one thing. Different painkillers act at different points in the chain between tissue damage and the conscious experience of pain, which is why matching the drug to the mechanism
It is bacteria evolving, not people becoming resistant — a distinction that matters, because the common phrasing suggests your body stops responding to antibiotics, which is not what happens. The
A formulary is an approved list of medicines a health organisation supports prescribing — the mechanism by which a large system applies consistent, evidence-based and cost-conscious decisions rather
There is no absolute legal right to a second opinion on the NHS — but requests are commonly accommodated, and knowing how to ask makes a considerable difference. The position. NHS guidance and
Different qualifications and different legal authority — and the roles have changed substantially, with many pharmacists now able to prescribe, which is not widely realised. Pharmacist. A registered
England charges a flat fee per item, with extensive exemptions — and the rest of the UK charges nothing, which is the difference most people are unaware of until they move. The four-nation position:
By making a request to whoever holds them — and since data protection law changed, it is free and does not require a reason, which is a significant improvement on the previous position. The right.
That a person understands what is proposed, the material risks, and the alternatives, and agrees voluntarily — and the legal standard in the UK changed significantly in 2015, in a way that shifted
A clinical decision recorded in someone's notes that cardiopulmonary resuscitation should not be attempted if their heart stops — and it is widely and distressingly misunderstood as meaning something
An urgent referral pathway for patients with symptoms that could indicate cancer, requiring them to be seen by a specialist within two weeks — and the most important thing to understand is that it is
