Yes, it is important to monitor your potassium intake during pregnancy. Potassium plays an essential role in the growth and development of a fetus, as well as helping maintain normal fluid balance and healthy blood pressure levels. Consuming too much or too little potassium can have serious implications for both mother and baby. High amounts of potassium can cause nausea, vomiting, constipation, weakness, tingling sensations in the extremities, irregular heartbeats and even cardiac arrest. Low levels of potassium can result in fatigue and muscle cramps due to inadequate nerve function and electrolyte imbalances. Therefore monitoring your potassium intake is important to ensure adequate levels are consumed throughout pregnancy for optimal health outcomes for both mother and baby.
