Start with what you feel

Symptoms

One symptom, several possible root causes, and the markers that tell them apart.

Most symptoms have more than one plausible cause, and several of them often run together, which is why chasing one at a time is so frustrating. These pages work backwards from what you actually feel: the root causes worth considering, the specific marker that distinguishes each, and the point at which it stops being a testing question and belongs with a doctor instead.

Energy and the nervous system

The most dismissed symptoms on this list, and the ones where the useful markers are least likely to have been run.

Hjernetåge

Thyroid, blood sugar, inflammation, B12, sleep. Five very different causes, five different markers.

Træt, men oppe at køre

Exhausted all day and awake at night. Mostly a body clock and blood sugar question.

Energidyk om eftermiddagen

Fine at nine, flattened at three. The gap between eating and crashing is the clue.

Vågner klokken tre om natten

A specific pattern, and what you notice on waking narrows it fast.

Angst uden grund

An overactive thyroid reads almost exactly like anxiety, and rarely gets checked.

Body and metabolism

Insulin governs fat storage and moves years before glucose does, which is why it sits under most of this group.

Kan ikke tabe mig

When effort is not the variable, insulin, thyroid and sleep usually are.

Sukkertrang

A correction signal rather than a character flaw, and the curve that creates it.

Altid kold

Cold when nobody else is. Heat production, and the conversion step TSH cannot see.

Kolde hænder og fødder

Warm core, cold fingers. That combination is a distribution question.

Hårtab

Iron stores, thyroid, and the three month delay that hides the cause.

Hævet ansigt om morgenen

Usually gravity. What matters is whether it has cleared by afternoon.

Gut, skin and joints

Oppustet efter maden

Timing after the meal narrows it faster than any single test.

Bumser som voksen

Where it sits, when it flares, and the insulin pathway underneath.

Ledsmerter

Morning stiffness duration separates inflammatory from mechanical, and the first one has a window.

Hormones

Lav sexlyst

Usually has a date attached, and something written next to that date.

Each page names the markers in the body text and links straight to what they mean and how to test them. Where a symptom can signal something serious, that is stated near the top rather than buried at the bottom.
