To keep it short & sweet, during pregnancy fluid volume increases by as much as 50% & electrolytes help to keep the body’s minerals in balance ✨
For the longer version, I’m going to share some quotes from a great article by about electrolytes & I’ll drop the link for the article in the comments.
“In the context of nutrition, electrolytes are essential minerals that carry an electric charge once dissolved in fluid. Sodium, potassium, chloride, calcium, and magnesium all act as electrolytes. In pregnancy, fluid volume increases by as much as 50% and this gradual increase starts fairly early in the first trimester. Not only does blood volume increase, but as baby grows and your uterus expands, amniotic fluid accumulates in the uterus where it:
Cushions baby
Supports lung development (baby “breathes” amniotic fluid, which has hormones, nutrients, and antibodies)
Maintains a consistent temperature
Supports their developing digestive system
Assists in nutrient delivery and the excretion of wastes
Helps baby’s skeletal and muscular system develop (amniotic fluid provides the right amount of room for baby to move and kick/punch the walls of the uterus to stimulate muscular growth and bone density)
Outside of these pregnancy-specific roles, adequate fluids allows for maintaining good circulation, provides shape and structure to every cell in your body, helps regulate body temperature, and aids in the digestion and absorption of nutrients.
As fluid needs go up, electrolyte needs increase in tandem. Electrolyte deficiencies carry risks, such as issues with fetal growth or certain pregnancy complications (to include blood pressure issues, like preeclampsia, as well as polyhydramnios).
