Constipation in pregnancy is very common. The hormone progesterone can cause unwanted side effects, including heartburn, varicose veins, haemorrhoids, and constipation. Before using laxatives, try natural methods such as drinking plenty of water and juice. Increase the fibre in your diet by eating lots of fresh fruit and veg, wholemeal bread and cereal.
Regular exercise can also help generally when your system becomes "sluggish". If you still need a laxative, ask your midwife, as she can recommend a gentle one that's suitable for use during pregnancy.
