Potassium

mmol/L · Vitamins & minerals

Serum potassium is an electrolyte essential for nerve, muscle, and cardiac rhythm — tightly regulated in pregnancy.

Low or high potassium can reflect vomiting, medications, renal handling, or acute illness — not diet alone. The app's sodium:potassium balance flag complements but does not replace a lab draw.

How to read it

Single values outside range need medical context. Dietary potassium from vegetables and fruit supports the Na:K ratio modelled in daily scoring.

Trimester context

Stage	For the mother	For the baby
First trimester	—	—
Second trimester	Expanding blood volume shifts electrolyte concentrations — compare to local pregnancy intervals.	Adequate maternal status supports placental perfusion.
Third trimester	Marked abnormalities raise arrhythmia and pre-eclampsia concern.	Severe maternal imbalance can affect fetal wellbeing.
