Pronounce as /ˌhaɪ.pɚˈɛm.ɪ.sɪs/ (US) or /ˌhaɪ.pərˈɛm.ɪ.sɪs/ (UK). Start with a light, unstressed ‘hy-’ leading into a strong secondary stress on the ‘em’ syllable, then a final ‘-sis’. The key is the secondary stress on the penultimate triplet, with the middle syllable reduced in US and expanded slightly in UK. Try breaking it into hi-PEM-eh-sis, but keep the ‘eh’ sound short and crisp. Audio resources: a medical diction line or pronunciation tool can confirm the /ˌhaɪ.pɚ/ vs /ˌhaɪ.pər/ vowel quality.”,
Common errors include: 1) Misplacing primary stress on the first syllable (haɪ-PER-ə-muh-sis) instead of the second syllable; 2) Reducing /ɪ/ differently in the 'em' component (em-ih-sis) leading to /ˌhaɪ.pɪˈɛm.ɪ.sɪs/; 3) Flattening the /r/ in US speakers where /ɚ/ or rhoticity affects the middle vowel. Correction: practice the pattern HI-pər-EM-ə-sis with clear secondary stress on EM; use minimal pairs to align the stress. Record and compare with a clinical pronunciation resource to ensure the /ɛm/ portion stands out clearly.
In US English you typically have a rhotic /r/ sound in the second syllable cluster and a slightly schwa-like second syllable: /ˌhaɪ.pɚˈɛm.ɪ.sɪs/. UK English often reduces the /ɚ/ to a schwa /ə/, yielding /ˌhaɪ.pəˈɛm.ɪ.sɪs/ with less rhoticity. Australian English tends toward /ˌhaɪ.pəˈɛm.ə.sɪs/ with even flatter vowels and a short, clipped second syllable. Across all variants, the primary stress remains on the 'em' syllable, with a secondary stress on the preceding 'hy' portion in many speakers; watch the rhoticity and diphthongization differences. Pronunciation practice should include listening to regional medical readings for accuracy.
It combines a long initial high-frequency prefix haɪ- with a multi-syllabic tilting emesis tail that contains a sequence of sibilants and a mid-central vowel (ɪ). The challenge is aligning the secondary stress on EM while maintaining clarity on the final -sis; many speakers blur the /ɛm/ into /ɛmɪ/ or misplace the stress. Also, subtle US /ɚ/ or UK /ə/ reductions in the middle syllable confound learners. Mastery comes from practicing the syllable in order, isolating the EM- syllable, and using IPA-guided feedback to normalize stress and vowel quality.
Some speakers wonder whether the prefix 'hyper-' changes in medical compounds, like 'hyperemesis' vs 'hyperemesis gravidarum'. The answer is that pronunciation stays steady across compounding; the prefix retains the /ˌhaɪ/ beginning, and the root -emesis remains the same. The challenge is ensuring the 'per-' or 'pər-' sound in the second syllable is not swallowed. Focus on the sequence hi-pə-REM-ə-sis and maintain the distinct /ɛm/ with a crisp final /sɪs/.

Hyperemesis derives from Greek hyper- ‘over, excessive’ and helein ‘to vomit’ (root: emesis). The combining form hyper- signals excess, followed by -emesis from emesis, used in medical terminology for vomiting. The term entered English medical usage in the late 19th to early 20th century as obstetricians described severe vomiting in pregnancy despite standard antiemetic therapy. It distinguished extreme vomiting from common nausea or mild emesis, especially when it caused dehydration, weight loss, or electrolyte disturbance. First known uses appear in medical literature around the 1880s–1920s, with early case reports in obstetrics detailing cases labeled as hyperemesis gravidarum, later refined to differentiate from other emesis-related conditions. Over time, the term became standard in obstetric practice, clinical guidelines, and pharmacologic discussions about management options. While often abbreviated as HEG in some texts, full usage remains common in formal medical writing and research abstracts. In modern usage, hyperemesis often implies a clinically significant condition requiring evaluation and potential hospital admission, beyond routine pregnancy-related vomiting. Pronunciation has remained consistent with stressing second syllable in many English variants, aligning with other medical terms built on emesis.
