Bloating and pregnancy: what to know

Pregnancy hormones can slow movement through the digestive tract, making gas, constipation and early fullness more noticeable. As pregnancy progresses, the growing uterus can add pressure to nearby organs. Bloating may also have a separate cause, such as food intolerance, lactose intolerance, irritable bowel syndrome, coeliac disease or an infection, so the timing and accompanying symptoms matter.

Try smaller meals spaced through the day, chew carefully and drink fluids regularly. Gentle walking may help bowel movement; ask your maternity team what activity suits you. Add fibre gradually if constipation is present, because a sudden increase can worsen gas. Check every medicine, laxative, supplement or herbal product with a pharmacist, midwife or doctor before using it. Nutrition counselling can help maintain a balanced intake when symptoms limit food choices.

Contact your maternity team promptly for persistent vomiting, inability to keep fluids down, painful urination, fever, or bloating with ongoing abdominal pain. Seek urgent help for sudden severe pain, vaginal bleeding, fainting, a rigid abdomen, or reduced fetal movement when you normally feel movement. Symptoms that are rapidly worsening should not be assumed to be ordinary pregnancy discomfort.

Ask which relief products are suitable at your stage of pregnancy and whether constipation, reflux or another problem is contributing. Tell the clinician when the bloating began, your bowel pattern, fluid intake, pain location, vomiting, bleeding, current medicines and any possibility of food-related symptoms.
