Experiencing more frequent bowel movements in the third trimester is a common occurrence. This change is a normal physiological adjustment as the body prepares for childbirth, indicating natural processes leading up to labor.
Hormonal and Physical Changes
Increased bowel activity in the third trimester is influenced by hormonal shifts and the growing uterus. As labor nears, the body produces higher levels of prostaglandins. These hormone-like substances ripen the cervix, stimulate uterine contractions, and can affect intestinal smooth muscles, leading to increased bowel activity and looser stools.
The growing uterus and baby exert significant pressure on the digestive tract, contributing to changes in bowel habits. This physical pressure can lead to more frequent bowel movements. The body’s natural preparation for labor also includes a “cleansing” effect, emptying the bowels to create more room for the baby’s descent through the birth canal.
While physiological changes are primary drivers, dietary factors can also play a minor role. Increased fiber intake to prevent constipation, or developing food sensitivities, can contribute to digestive upset and altered bowel patterns.
When to Seek Medical Advice
Distinguishing between normal increased bowel movements and symptoms requiring medical attention is important. Normal changes typically involve more frequent, but still formed or slightly looser, stools. True diarrhea, however, is characterized by loose, watery stools, often accompanied by urgency, occurring three or more times within a 24-hour period.
Contact a healthcare provider for severe abdominal pain or cramping, fever, chills, or blood in the stool. Signs of dehydration, including excessive thirst, dry mouth, dark urine, decreased urination, or dizziness, also require medical attention.
Increased bowel movements can precede labor, but are usually accompanied by other signs if labor is truly imminent. These additional signs might include regular contractions, ruptured membranes (water breaking), or loss of the mucus plug. If combined with concerning symptoms or worries about preterm labor, consult a doctor or midwife.
Managing Digestive Comfort
Maintaining digestive comfort involves several steps. Stay well-hydrated, especially if stools are looser, to prevent dehydration. Drink adequate fluids, primarily water, throughout the day.
Dietary adjustments can help manage discomfort. Choose easily digestible foods and avoid spicy, greasy, or high-fat items that may exacerbate digestive upset. A balanced diet of fruits, vegetables, and whole grains supports digestive health.
Perianal hygiene helps prevent irritation if bowel movements are frequent. Gently clean the area after each movement to maintain comfort.
Always discuss persistent or concerning digestive symptoms with a healthcare provider for appropriate guidance and care.
