It's common for your bowel habits to change during pregnancy. Most women notice some constipation, often accompanied by irregular bowel movements. Hemorrhoids may occur more often. You can help yourself avoid constipation problems during pregnancy. Increase your fluid intake.
Exercise also helps.
Many doctors suggest a mild laxative, such as milk of magnesia or prune juice, if you have problems. Certain foods, such as bran and prunes, can increase the bulk in your diet, which may help relieve constipation. If constipation is a continuing problem, discuss treatment with your doctor. Try not to strain when you have a bowel movement, if you are constipated. Straining can lead to hemorrhoids.
