Dehydration Causes OB Contractions? YES, and NO.
Manage episode 444510624 series 2280622
Proper hydration is important for physiology whether male or female, and if female… hydration in pregnancy is important for proper uterine blood flow and proper amniotic fluid production. Interestingly, water recommendations do not specify differential water needs or hydration status recommendations by pregnancy month or trimester, nor do they take into account body composition, knowing that overweight and obesity increase the probability of being underhydrated. During pregnancy, dehydration is thought to contribute to Braxton-Hicks contractions possibly due to lactic acid buildup in the myometrial cells or via reflex secretion of ADH (vasopressin). But this is theoretical. Here is where IV hydration comes into clinical practice. What's hoped for in administering intravenous (IV) hydration is that the fast fluid volume increase will stop uterine activity and hence avert cervical change. Theoretically, hydration may reduce uterine contractility by increasing uterine blood flow and by decreasing pituitary secretion of antidiuretic hormone and oxytocin. Does mild-moderate dehydration lead to preterm labor? Is IV hydration a way to prevent preterm birth. There has been data since the 1980s up until 2021 which says, “No”. Listen in for details.
