Loose motion and vomiting in pregnancy

Diarrhoea and vomiting may happen with gastroenteritis or food poisoning. Pregnancy-related nausea can occur alongside a separate bowel illness, so do not assume every episode is ordinary morning sickness. Gallstones, migraine, or pancreatitis can also cause vomiting or abdominal symptoms, while rotavirus infection is one infectious possibility. The pattern matters: note when symptoms began, how often you are passing urine, whether you have fever or abdominal pain, and whether anyone else who shared food is ill. Vomiting is a symptom rather than a diagnosis.

Take frequent small sips of water or an oral rehydration drink if you can keep fluids down. Rest, wash hands carefully, and return to light foods gradually when nausea eases. Avoid taking anti-diarrhoea, anti-sickness, or herbal products unless a maternity clinician or doctor confirms they are appropriate in pregnancy. Keep a record of fluids, urine, pain, fever, and any blood in vomit or stool so the clinician can assess the situation.

Contact your maternity team or seek urgent care if you cannot keep fluids down, pass very little or dark urine, feel faint or confused, have severe or persistent abdominal pain, blood in vomit or stool, a high fever, a stiff neck, or signs of dehydration. Seek urgent advice as well if you are worried about reduced fetal movement or contractions. Severe headache with vomiting needs assessment because it may reflect a condition such as [Meningitis](/conditions/meningitis/) or another urgent problem; symptoms do not identify the cause on their own.

Ask which rehydration product and anti-sickness option are suitable for you, whether you need blood or urine tests, how to monitor fetal wellbeing, and which changes should bring you back for review.
