Key message: Hormonal change and pressure from the growing uterus commonly cause heartburn, constipation and piles. Small lifestyle changes and pregnancy-compatible medicines can help, but bleeding or severe pain should not be assumed to be harmless.
Get urgent help: Seek urgent care for severe or persistent abdominal pain, repeated vomiting, vomiting blood, black stools, heavy rectal bleeding, faintness, inability to pass stool or gas with swelling, fever, or pregnancy pain with bleeding or contractions.
Why does heartburn happen?
Pregnancy hormones relax the valve between the stomach and oesophagus, while the growing uterus increases pressure. Symptoms include burning behind the breastbone, acid taste, burping or nausea after food.
What helps heartburn?
- Smaller meals and avoiding lying down soon after eating.
- Identifying personal triggers such as very fatty, spicy or acidic food without unnecessary restriction.
- Raising the head and shoulders for sleep and lying on the left side if comfortable.
- Avoiding smoking and alcohol.
- Using an antacid or alginate confirmed as suitable in pregnancy; separate some products from iron or folic acid as advised.
- Discussing an acid-suppressing medicine when symptoms persist.
Why does constipation happen?
Progesterone slows the bowel, activity and diet may change, and iron tablets can worsen constipation. Passing hard stool and straining can contribute to piles.
What helps constipation?
- Increase fibre gradually from vegetables, fruit, pulses and whole grains.
- Drink enough fluid and remain physically active when medically able.
- Use a regular unhurried toilet routine and do not ignore the urge.
- Review the type or dose of iron rather than stopping it if anaemia treatment is needed.
- A bulk-forming or osmotic laxative may be recommended; stimulant medicines are selected individually.
What are piles?
Haemorrhoids are swollen veins around or inside the anus. They can cause itching, discomfort, a lump or bright-red blood on toilet paper.
Rectal bleeding still deserves review, especially if persistent, mixed with stool, dark, associated with weight loss or not clearly from piles.
What helps piles?
- Prevent constipation and straining.
- Avoid sitting on the toilet for long periods.
- Use cool compresses or a warm bath for comfort.
- Choose a pregnancy-compatible local cream or suppository after pharmacist or clinician advice.
- Seek assessment for severe pain, a hard painful lump, ongoing bleeding or symptoms that do not improve.
Can these symptoms indicate something else?
Chest pain with breathlessness is not simply heartburn until assessed. Severe right-upper-abdominal pain with headache or visual symptoms may relate to pre-eclampsia. Persistent vomiting, fever or focal abdominal pain can have other causes.
Do not treat a new severe symptom repeatedly without review.
Frequently asked questions
Can I take antacids with iron?
Some antacids reduce absorption, so separate doses according to pharmacist or clinician advice.
Should I stop iron if it causes constipation?
No. Ask about a different preparation, dose or bowel plan.
Is bright-red blood always piles?
No. Piles are common, but persistent or unexplained rectal bleeding needs assessment.
Are laxatives safe in pregnancy?
Several are used safely, but the best type depends on symptoms and medical history.
Does heartburn mean the baby has hair?
No reliable clinical decision should be based on this popular belief.
Your next step
Discuss persistent digestive symptoms and all medicines or supplements at antenatal visits. Significant bleeding, severe pain or systemic symptoms need prompt assessment.
