Medical Review Policy

Maintained by the HealthMedHub Editorial Team · Published October 2026 · Reviewed October 2026

Health information is different from most content on the internet: a reader may act on it, and a wrong number can cause real harm. This policy sets out how we try to prevent that. It applies to every health guide, food reference page and calculator on HealthMedHub.

Scope

This policy covers three kinds of content: health guides (explanatory articles), food and nutrition reference pages (nutrient values and serving context), and calculators (BMI, calorie and BMR estimates, sleep timing, pregnancy dating, and clinical scores such as MELD-Na or CURB-65). Clinical scores are reference tools for understanding how a published score is built; they are not diagnostic instruments and must not be used to make treatment decisions.

Where a topic is genuinely contested, we describe the disagreement rather than picking a side. Where the evidence is thin, we say the evidence is thin. Where a popular belief is not supported — for example, supplement claims that go well beyond the data — we say so, and we link to the body that says so.

Source Hierarchy

Not all sources carry equal weight. We work down this list and prefer the highest tier that covers the question:

1. Tier 1 — national public-health and clinical guidance. CDC, NHS, NIH institutes (including NHLBI, NIDDK and NCCIH), plus equivalent national bodies. Used for thresholds, recommendations and safety advice.
2. Tier 2 — international bodies. WHO and comparable agencies. Used for population-level guidance and nutrient intake references.
3. Tier 3 — peer-reviewed literature. Systematic reviews and randomised trials first, observational studies with their limitations stated, and never a single small study presented as settled science.
4. Tier 4 — academic medical centres. Mayo Clinic and MedlinePlus for clinical overviews and patient-facing explanations.

We do not use supplement retailers, affiliate content, press releases or unmoderated forums as the basis for a health claim. If a claim exists only in commercial marketing, it does not belong on this site.

How Review Works

Content is reviewed before publication and again on a rolling schedule. A review covers four things: accuracy (is the statement true, and does the cited source actually say it?), proportion (does the strength of the wording match the strength of the evidence?), safety (could a reasonable reader be harmed by acting on this?), and currency (has the guidance changed since the last review?).

Reviewers are instructed to be adversarial with our own text: to look for the sentence that overstates a finding, the figure that has no source, and the missing caveat. Rewriting for caution is expected; quietly deleting an inconvenient limitation is not. Corrections are recorded on the page, and the review date shown on each article is updated whenever its substance changes.

Calculators and Formulas

Every calculator on this site uses a published formula, and each formula is named on the page that uses it. We test each tool with known values from the source, with boundary values, and with deliberately extreme inputs to confirm that it cannot return impossible output such as a negative cholesterol value, a missing result, or a score outside the defined range.

We also state the limits of each formula. The Friedewald equation is unreliable at high triglycerides, so we refuse to display an estimate there rather than showing a misleading one. MELD-Na applies the sodium correction only above a MELD score of 11, as the allocation policy requires. Where a formula was derived in adults above a certain height or age, we say so. Estimates are estimates; a calculator cannot examine you.

Update Schedule

Guides and reference pages are re-reviewed at least every twelve months, and immediately when a source we rely on changes, when a reader reports a possible error, or when a linked page stops resolving. Calculators are re-checked against their source formulas at the same interval. Food data is taken from published nutrient databases and re-checked when those databases are revised.

If a page has not been reviewed recently, you will see it in the review date at the top of the article. A stale date is not necessarily a sign of stale content, but we treat it as a prompt to look again.

Safety and Limits

We avoid instructions that require clinical judgement: no dosing, no tapering schedules, no "stop your medication" advice, no interpretation of your personal test results. Mental-health screening pages carry an explicit safety notice about thoughts of self-harm, and tools that involve medical emergencies point to urgent care rather than to a routine appointment.

If you are unwell, contact a doctor or pharmacist. If you think you are having a medical emergency — chest pain, difficulty breathing, signs of a stroke, severe bleeding, or risk of harming yourself — contact your local emergency number immediately rather than reading a web page.
