vimārgagamana: what the term means and how it is translated
vimārgagamana विमार्गगमन is an Ayurvedic technical term. It is rendered into English in 5 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

Body channel dysfunction involving displacement of contents
WHO International Standard Terminologies on Ayurveda (2022) · Entry ITA-4.8.7, section 4.8, p. 116; Sanskrit vimārgagamanam / विमार्गगमनम्; description "Diversion to the flow of the contents and movement in the wrong body channels." · standards-body
WHO's English term ('displacement of contents') and its description ('movement in the wrong body channels') pull in slightly different directions, displacement of a substance versus travel down a wrong route. The Sanskrit is unambiguous: vi-mārga = wrong road, gamana = going.

diviations (of the elements from their own into other channels)
Charaka Samhita, tr. Avinash Chandra Kaviratna (public domain) · Vimana Sthana Lesson V, aphorism 31 (= Ca.Vi.5/24) · public-domain-translation
'diviations' is an OCR artifact for 'deviations' in the archive.org scan. Kaviratna's parenthesis is an accurate unpacking: the dhatus leaving their own channels for others. This is the most faithful public-domain English available.
Vimarga Gaman (Opposite Direction Flow)
Sharma S et al., Int. Res. J. Ayurveda & Yoga 6(12):98-102 (2023) · DOI 10.47223/IRJAY.2023.61218, section 3.11.4 · modern-journal-review
A common but narrower textbook rendering. 'Opposite direction' is only one case of 'wrong route'; the paper's own example (udakavaha and svedavaha channels in jwara samprapti) is not about reversal at all.

vimārgagamana as the fourth sign of srotodushti. The only verified classical occurrence of the term I located.

or diviations (of the elements from their own into other channels), are regarded as indications of the vitiation of the ducts.
The lawfully quotable English. His parenthesis makes explicit what WHO's 'displacement of contents' leaves vague: it is the dhatus/contents leaving their proper channel for another channel.
Where this term does work in the theory
One concept record names this term as one of its components, and glosses it there as follows.
- Srotas (the channel system) and srotodushti as Vimargagamana
- Diversion of the channel's contents into a channel not its own (fourth mode)
Not to be confused with
- pratiloma gati
- Movement against the normal direction (retrograde), as in pratiloma vata. That is reversal along the SAME path. vimārgagamana is departure onto a DIFFERENT path. Textbook renderings that say 'opposite direction flow' conflate the two.
- prasara (प्रसर)
- The third stage of shatkriyakala, in which aggravated doshas overflow their own seats and spread through the body. That is a normal-for-pathology stage of dosha movement; vimārgagamana is a sign of the CHANNEL being vitiated. They are described at different levels of the model.
- saṅga
- Frequently the cause of vimārgagamana rather than an alternative to it, WHO's own saṅga entry notes obstruction 'sometimes resulting in the formation of a collateral pathway'. The four signs are not independent.
- ativyāpti / dhātu-sāṅkarya
- Terms occasionally used in secondary literature for mixing of tissue elements. Not the same as a content travelling a wrong channel.
Renderings that do not hold
- opposite direction flow / retrograde flow. The commonest error. vi-mārga is 'wrong road', not 'reverse road'. Retrograde flow is pratiloma. Vomiting is often cited as the example, but vomiting is only one instance and not the paradigm case.
- extravasation. A vascular-specific biomedical term. vimārgagamana applies across all thirteen channels including annavaha and purishavaha, where extravasation is meaningless.
- shunting. Attractive because WHO's saṅga entry mentions collateral pathways, but shunt implies an anatomically defined abnormal connection, which the Sanskrit does not assert.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Whether Chakrapani or any commentator gives worked examples of vimārgagamana, and whether they include reversal as a case.
- Whether the term occurs anywhere in Sushruta. I did not find it, but my Sushruta full-text search covered only the Nidana and Sharira sthanas of the Bhishagratna scan, so absence is not established.
- Whether NAMASTE or ICD-11 TM2 carries any code whose definition depends on this concept.
