Acidity and vomiting in pregnancy

Try small, plain meals, take frequent sips of fluid, and stay upright after eating. Before using an antacid, anti-sickness medicine, herbal product, or supplement, check with a maternity clinician or pharmacist that it is appropriate during pregnancy.

Pregnancy-related hormonal changes can slow digestion and relax the valve between the stomach and oesophagus, allowing acid to move upward. As the uterus grows, pressure on the stomach can add to heartburn or regurgitation. Nausea and vomiting may occur separately from reflux and can be worse when the stomach is empty.

Not every episode is pregnancy-related. Gastroenteritis commonly presents with vomiting and diarrhoea, while gallstones may present with upper-right abdominal pain and nausea. Fever, diarrhoea, headache, urinary symptoms, or pain in one particular area offers useful clues and deserves discussion with a clinician.

Eat slowly and choose smaller portions more often. Keep a simple snack nearby if an empty stomach triggers nausea. Separate drinks from large meals if fullness worsens reflux, but continue taking small sips through the day. Sit upright after food and raise your upper body for sleep if night-time reflux troubles you.

Notice personal triggers such as fatty meals, chilli, citrus, caffeine, or strong smells instead of imposing a broad diet restriction. If fluids are difficult, try cool drinks or oral rehydration solution in repeated small amounts. A clinician can recommend pregnancy-compatible treatment when lifestyle changes are not enough.

Contact your maternity service promptly if you cannot keep fluids down, pass very little or dark urine, feel faint, become unusually drowsy, or continue losing weight. Repeated vomiting can cause dehydration and may need prescribed medicine or fluids.

Seek urgent assessment for vomiting blood, green vomit, severe or localised abdominal pain, a severe headache with visual changes, fever with neck stiffness, chest pain, breathing difficulty, vaginal bleeding, fluid leakage, or a noticeable reduction in your baby's usual movements after movements have become established.

Explain when vomiting began, how often you can drink and urinate, whether reflux or pain accompanies it, and which medicines or supplements you take. Ask which acid and anti-sickness treatments are suitable, how to maintain hydration, and what change should trigger a same-day review.
