Pregnancy brings many changes, including Braxton Hicks contractions and occasional diarrhea. These common occurrences can raise questions about their connection. This article explores Braxton Hicks contractions and diarrhea during pregnancy, clarifying potential links.
Understanding Braxton Hicks Contractions
Braxton Hicks contractions are sensations of uterine tightening, often called “practice contractions” or “false labor.” While they can begin early, most individuals typically notice them in the second or third trimester. These contractions feel like an uncomfortable, but usually not painful, tightening across the abdomen.
Braxton Hicks contractions tone the uterine muscle and prepare the cervix for birth. They are irregular in frequency and intensity, and generally do not increase in strength or duration over time. Unlike true labor, they often subside with changes in activity or position, such as walking or resting.
Diarrhea During Pregnancy
Diarrhea, defined as three or more loose or liquid bowel movements in 24 hours, is common during pregnancy. It can occur for various reasons, many unrelated to pregnancy. Common causes include hormonal changes, such as prostaglandin level fluctuations that increase digestive tract movement.
Dietary adjustments, new food sensitivities, or prenatal vitamin side effects can also contribute. Minor infections like stomach bugs or food poisoning are frequent culprits for diarrhea in pregnant individuals, similar to the general population.
The Connection Between Braxton Hicks and Diarrhea
Braxton Hicks contractions do not directly cause diarrhea. These symptoms typically arise from different physiological processes. Braxton Hicks relate to uterine activity and labor preparation, while diarrhea is a digestive system response influenced by hormones, diet, or external factors.
However, both can co-occur, especially as pregnancy advances into the third trimester. This co-occurrence is often due to the body preparing for labor, where increased prostaglandin levels can trigger both uterine contractions and increased bowel motility. Diarrhea can be an early sign of impending labor for some, though it is not a symptom of Braxton Hicks themselves.
Telling the Difference Between Braxton Hicks and Labor
Distinguishing Braxton Hicks contractions from true labor contractions is important as the due date approaches. Braxton Hicks are irregular in timing and intensity, and tend to ease with movement or position changes. They usually do not increase in frequency, duration, or strength. True labor contractions, in contrast, occur at regular intervals, become progressively stronger and longer, and get closer together over time.
True labor contractions do not subside with activity changes and often cause pain that wraps from the back to the front of the abdomen. When diarrhea is present, it might indicate the body is beginning the process of labor, especially if accompanied by other signs like regular contractions, a lower back ache, or changes in vaginal discharge. This combination of symptoms can signify the onset of true labor.
When to Contact Your Healthcare Provider
While Braxton Hicks contractions and occasional diarrhea are common during pregnancy, certain signs warrant medical attention. Contact a healthcare provider if diarrhea lasts longer than 24 to 48 hours, or if accompanied by severe abdominal pain, fever, chills, or blood or mucus in the stool. Signs of dehydration, such as decreased urination, dark yellow urine, dry mouth, excessive thirst, or dizziness, require prompt medical consultation.
Regarding contractions, seek medical advice if they become more frequent, stronger, or regular, especially before 37 weeks of pregnancy. Report any vaginal bleeding, leaking fluid, or a noticeable decrease in fetal movement. These symptoms could indicate a more serious condition requiring immediate evaluation.
