Hiccups at 36 weeks pregnant: what to know

A hiccup is an involuntary spasm of the diaphragm followed by quick closure of the vocal cords. In late pregnancy, the growing uterus can crowd the stomach and change how comfortably you digest a meal. Eating quickly, a large meal, fizzy drinks, or acid moving upwards can irritate the diaphragm. Hiccups themselves do not tell you whether labour has started and do not reliably show how your baby is doing.

If hiccups come with burning behind the breastbone, sour fluid, nausea, or discomfort after meals, discuss possible acid reflux with your maternity clinician. Hiccups accompanied by upper-abdominal pain or repeated vomiting may need assessment for another cause.

Sit upright, loosen tight clothing, and take slow, comfortable breaths. Sip water, eat smaller portions, and avoid lying flat soon after eating. Notice whether a particular food or drink triggers the episodes. Do not hold your breath for a long time, frighten yourself, or use forceful swallowing tricks during pregnancy.

Do not start an over-the-counter remedy or acid-reflux medicine without checking that it is suitable for pregnancy. A clinician or pharmacist can recommend an option if reflux is contributing.

Contact your maternity unit promptly if hiccups occur with vaginal bleeding, leaking fluid, regular painful contractions, severe abdominal pain, chest pain, trouble breathing, fainting, or repeated vomiting. Seek urgent advice if your baby’s movements are less than usual or feel noticeably different; do not wait for the hiccups to stop.

Arrange a routine review if episodes keep returning, disturb sleep, make eating difficult, or continue alongside reflux symptoms. The clinician can review your symptoms, medicines, hydration, and pregnancy history.

Ask whether your pattern sounds like reflux, whether a pregnancy-safe treatment is appropriate, and which symptoms should prompt a call to the maternity unit. Mention when the hiccups began, how long each episode lasts, what you had eaten, and any change in fetal movement.
