PUQE-24 score

How severe is my pregnancy nausea?

In the last 24 hours, for how long have you felt nauseated?
In the last 24 hours, how many times have you vomited?
In the last 24 hours, how many times have you had retching or dry heaves without bringing anything up?
Answer all three questions to see your PUQE-24 score.

What is the PUQE score?

PUQE-24 (Pregnancy-Unique Quantification of Emesis, 24-hour version) — 3-question validated scale grading nausea and vomiting in pregnancy on a scale of 3-15. Used worldwide to triage symptoms and track treatment response. Asks about hours of nausea, vomiting episodes, and retching episodes in the last 24 hours. Takes 2 minutes.

What do PUQE scores mean?

  • 3-6 (mild): manage with diet, ginger, B6, rest. Most pregnant women.
  • 7-12 (moderate): prescription antiemetics, hydration support, possibly day-case IV fluids.
  • 13-15 (severe): highly suggestive of hyperemesis gravidarum. Urgent clinical care; IV fluids, IV antiemetics, possible admission.

What is hyperemesis gravidarum?

Severe pregnancy nausea and vomiting causing dehydration, weight loss, electrolyte imbalance, ketosis. ~1-3% of pregnancies. NOT just bad morning sickness — distinct clinical entity. RCOG diagnostic criteria: persistent vomiting + weight loss ≥ 5% pre-pregnancy weight + ketonuria + electrolyte abnormalities. Can be life-threatening untreated (Wernicke’s from B1 deficiency, Mallory-Weiss tears from retching). NEEDS treatment.

What helps at home (mild)?

  • Small frequent meals every 2-3 hours.
  • Bland foods first thing — crackers, dry toast before getting up.
  • Ginger (tea, biscuits, capsules) — Cochrane-reviewed evidence.
  • Avoid trigger smells — cooking, perfume, certain foods.
  • Cold foods often better tolerated.
  • Stay hydrated — sip electrolyte drinks if vomiting.
  • Acupressure wrist bands — mixed evidence; low harm.
  • Vitamin B6 / pyridoxine 10-25 mg 3x/day — good evidence.
  • Rest.

Prescription antiemetics (moderate-severe)

  • Doxylamine + pyridoxine (Diclectin / Diclegis / Xonvea) — FDA pregnancy category A. First-line.
  • Cyclizine — UK first-line, ~50 mg every 8h.
  • Promethazine — sedating antihistamine; useful at night.
  • Metoclopramide — dopamine antagonist; UK limited to 5 days.
  • Ondansetron — strong efficacy; small risk of cleft palate at < 10 weeks; QT caution.
  • Prochlorperazine (Stemetil) — common UK.
  • Oral prednisolone — severe resistant HG.

When to go to A&E or maternity unit

Same-day urgent care if:

  • Can’t keep ANY fluids down for 4+ hours.
  • Signs of dehydration (dizzy, fainting, very dry mouth, no urine for 8+ hours).
  • Vomiting blood (Mallory-Weiss tear from retching).
  • Severe abdominal pain.
  • Severe headache or vision changes.
  • Confusion or hallucinations (Wernicke’s).
  • Not improving on oral antiemetics.
  • Weight loss > 5% of pre-pregnancy.

How long does pregnancy nausea last?

  • Typical window: 4-12 weeks.
  • Peak: 8-10 weeks.
  • Resolution: 12-14 weeks for ~80%.
  • ~20% have ongoing nausea past 20 weeks.
  • ~5% nauseated throughout pregnancy.
  • HG: often persists into second trimester or whole pregnancy.
  • After delivery: resolves immediately.

Different scenarios — what your score means

Scenario 1: PUQE 5 at 7 weeks, can eat small meals, mild vomiting morning only

Mild. Tier 1 measures — small frequent meals, ginger, B6. Will likely improve by 14 weeks.

Scenario 2: PUQE 9 at 10 weeks, vomiting 4-5x/day, can keep some fluids down

Moderate. GP visit for cyclizine or doxylamine/B6. Monitor weight, urine output. If not improving in a week, escalate.

Scenario 3: PUQE 14 at 12 weeks, can't keep anything down, lost 4 kg

Likely hyperemesis gravidarum. Same-day maternity unit / A&E. IV fluids, IV antiemetics (ondansetron, cyclizine), urine ketones, electrolytes. Likely 24-hour admission for stabilisation.

Scenario 4: Second pregnancy, had HG last time, currently 6 weeks and starting nausea

80% recurrence risk. Pre-emptive doxylamine/B6 reasonable. Early antenatal review. Emergency plan ready. Don’t wait until severe to seek help.

Scenario 5: Nausea since week 6, now 22 weeks, still vomiting daily

Prolonged NVP. Continue antiemetics. Worth reviewing — rule out other causes (UTI, thyroid, gallbladder, twin pregnancy). Continue antiemetic plan; usually settles by 28 weeks for most.

Care guidance — surviving pregnancy nausea

  • Pre-emptive eating — small protein-rich snack every 2 hours; never let blood sugar drop.
  • Crackers by the bed — eat 2 before getting up.
  • Mild-flavour toothpaste (kids’ or sensitive).
  • Stay hydrated — small sips constantly; ice chips if struggling.
  • Ginger — tea, biscuits, capsules, ginger ale (real ginger).
  • Avoid trigger smells — cook outside if needed; partner cooks; takeaway / frozen meals temporarily.
  • Fresh air, cool room, lying down on side.
  • B6 10-25 mg 3x/day.
  • Don’t feel guilty for not eating “perfectly”.
  • Time off work if you need it — not weakness.
  • Mental health — severe nausea is exhausting and demoralising. Look after yours.

Common myths debunked

  • “It’s just morning sickness, push through” — severe nausea / HG is a medical condition needing treatment.
  • “Antiemetics will harm baby” — commonly-used antiemetics have decades of safety data; the bigger risk is untreated severe nausea.
  • “Bad nausea = healthy pregnancy” — mild NVP is associated with lower miscarriage; SEVERE HG is a problem to TREAT, not celebrate.
  • “It’s only morning sickness” — many women have nausea all day, not just morning.
  • “Saltines and ginger should be enough” — for mild, yes. For HG, no.

Frequently asked questions

What is the PUQE score for pregnancy nausea?
PUQE-24 (Pregnancy-Unique Quantification of Emesis, 24-hour version) — a validated 3-question scale that grades the severity of nausea and vomiting in pregnancy on a scale of 3-15. Used by obstetric teams worldwide to triage symptoms and track response to treatment. Asks about: (1) hours of nausea in last 24h; (2) episodes of vomiting in last 24h; (3) episodes of retching in last 24h. Each scored 1-5. Takes 2 minutes.
What do PUQE scores mean?
SCORE 3-6: MILD nausea/vomiting — usually managed with diet, ginger, B6, rest. Most women in pregnancy have this. SCORE 7-12: MODERATE — benefits from prescription antiemetics (doxylamine/B6, cyclizine, promethazine), hydration support, possibly day-case IV fluids. SCORE 13-15: SEVERE — highly suggestive of hyperemesis gravidarum (HG). Needs urgent clinical evaluation; usually IV fluids, IV antiemetics, possible admission, electrolyte and ketone monitoring.
What is hyperemesis gravidarum (HG)?
Severe pregnancy nausea and vomiting causing dehydration, weight loss, electrolyte imbalance, and ketosis. Affects ~1-3% of pregnancies. NOT just bad morning sickness — distinct clinical entity. Diagnostic criteria (RCOG): persistent vomiting in pregnancy AND weight loss ≥ 5% pre-pregnancy weight AND ketonuria (ketones in urine) AND electrolyte abnormalities. Can be life-threatening if untreated (Wernicke's encephalopathy from B1 deficiency, Mallory-Weiss tears from retching). NEEDS treatment — not a normal part of pregnancy.
What can I do for pregnancy nausea at home?
Tier 1 lifestyle: SMALL FREQUENT MEALS (every 2-3 hours); BLAND foods first thing (crackers, dry toast before getting up); GINGER (tea, biscuits, capsules — strong Cochrane evidence); AVOID trigger smells (cooking, perfume, certain foods); COLD foods often better tolerated; STAY HYDRATED (sip electrolyte drinks if vomiting); ACUPRESSURE wrist bands (mixed evidence, low harm); REST. Tier 2 OTC: VITAMIN B6 / PYRIDOXINE 10-25 mg 3x/day (good evidence). If not improving in 1-2 weeks or PUQE 7+, see GP for prescription antiemetics.
Which anti-nausea medicines are safe in pregnancy?
Several with good safety records. FIRST-LINE: DOXYLAMINE + PYRIDOXINE (Diclectin / Diclegis / Xonvea) — FDA pregnancy category A, antihistamine + B6 combo. CYCLIZINE — UK NHS first-line, antihistamine, ~50 mg every 8h. PROMETHAZINE — sedating antihistamine, useful at night. METOCLOPRAMIDE — dopamine antagonist; UK limited to 5 days due to extrapyramidal side effects. ONDANSETRON — strong evidence for efficacy; small risk of cleft palate at < 10 weeks (still used when benefit outweighs); QT prolongation. PROCHLORPERAZINE (Stemetil) — phenothiazine, common UK. STEROIDS (oral prednisolone) — for severe HG resistant to other antiemetics, RCOG guideline.
When should I go to A&E or maternity unit for nausea?
Same-day urgent care if: can't keep ANY fluids down for 4+ hours; signs of dehydration (dizzy, fainting, very dry mouth, no urine for 8+ hours); vomiting blood (Mallory-Weiss tear from retching); severe abdominal pain; severe headache or vision changes; confusion or hallucinations (Wernicke's encephalopathy from B1 deficiency); not improving on oral antiemetics; weight loss > 5% of pre-pregnancy. Maternity day-case unit or A&E — IV fluids, IV antiemetics, electrolyte and ketone monitoring.
What is ketonuria and why does it matter in pregnancy?
Ketones in urine — body's signal that it's burning fat for energy because not getting enough food / fluid. In pregnancy: ketones can cross placenta and may affect fetal development (animal studies suggest impact on neurodevelopment; human evidence less clear). Symptom of inadequate intake from severe vomiting. NHS / RCOG: ketonuria 3+ on dipstick is one of the HG diagnostic criteria. Indicates need for urgent IV fluid replacement and antiemetic treatment. Easily checked with urine dipstick at maternity unit.
Will pregnancy nausea harm my baby?
MILD-MODERATE: no harm; some evidence women with morning sickness have LOWER miscarriage rate (suggests viable pregnancy hormones). SEVERE / HG WITHOUT TREATMENT: can cause low birth weight, preterm birth, neurodevelopmental issues from maternal malnutrition / electrolyte imbalance / Wernicke's encephalopathy. WITH TREATMENT (antiemetics, IV fluids): outcomes usually normal. KEY MESSAGE: don't tolerate severe vomiting believing it's normal pregnancy. Get treated. Antiemetics used in pregnancy for decades have strong safety data.
How long does pregnancy nausea last?
Typically 4-12 weeks of pregnancy. PEAK: 8-10 weeks. RESOLUTION: 12-14 weeks for most (~80%). 20% have ongoing nausea past 20 weeks. ~5% have nausea throughout pregnancy. HG: more often persists past first trimester, sometimes whole pregnancy. After delivery, resolves immediately. Each pregnancy can differ — having HG in one pregnancy raises risk for next pregnancy (~80% recurrence; lower if previously treated proactively).
Can I take normal anti-sickness tablets like for travel sickness?
Some yes, with care. Most travel-sickness tablets ARE antihistamines (cyclizine, promethazine, cinnarizine) — many of these are used in pregnancy nausea. BUT: don't self-medicate with random brands. Check with GP / pharmacist FIRST. Some travel-sickness brands include other ingredients (caffeine, decongestants) not pregnancy-safe. STICK WITH brands your provider prescribes or recommends.
What's the difference between morning sickness and hyperemesis?
MORNING SICKNESS (typical): nausea and occasional vomiting, manageable with food, fluids, lifestyle measures. Usually able to keep some food and fluids down. Maintains weight or has small loss. PUQE 3-6. Affects 70-80% of pregnant women. HYPEREMESIS GRAVIDARUM: persistent severe vomiting, can't keep fluids down, dehydration, weight loss > 5%, ketonuria, electrolyte disturbance. PUQE 13+. Affects 1-3%. Requires urgent treatment. Severity vs intensity — not a continuum; some women have HG without especially 'sicker' symptoms but with dehydration risk.
Are there triggers I should avoid?
COMMON TRIGGERS: cooking smells (especially meat, garlic, onions, fish); strong perfume / scent; certain foods (often spicy, fatty, sweet, sour); empty stomach (low blood sugar worsens nausea); strong tastes (toothpaste — try mild flavour); bright light; warm rooms; sudden movements; tiredness. Personal — vary by woman. Keep a TRIGGER LOG to identify yours. Sometimes pregnancy creates aversions to foods you previously loved — listen to your body, eat what you can tolerate.
Can I work with severe pregnancy nausea?
Maybe. Some women cope with mild-moderate nausea at work with adjustments (snacks at desk, fresh-air breaks, anti-sickness meds). Severe HG often makes work impossible — frequent vomiting, dehydration, exhaustion. UK / US: pregnancy-related sickness counts as sickness absence; risk assessments under Equality Act 2010 (UK) / ADA accommodations (US) may apply. Talk to occupational health. Don't push through if you can't — getting treated is the priority.
What is pregnancy sickness support?
Pregnancy Sickness Support UK — charity supporting women with NVP / HG (pregnancysicknesssupport.org.uk). Help: peer support helpline, online forum, information leaflets, advocacy. HER Foundation (US) — Hyperemesis Education and Research Foundation (hyperemesis.org). Both offer evidence-based info, support networks, links to specialist clinicians. Particularly useful for women whose GP / midwife isn't taking severe nausea seriously enough.
Will my next pregnancy be the same?
Often yes. Recurrence rate for HG: ~80% if untreated; lower with proactive treatment. Recurrence for milder NVP also common. Strategies for next pregnancy: START ANTIEMETICS BEFORE symptoms hit (pre-emptive doxylamine/B6); plan early antenatal review; have emergency plan ready (which medicines, when to go to hospital); ensure family / employer aware. Some women find subsequent pregnancies milder; for many, especially HG, the recurrence is real and worth preparing for.
