Everything Pregnant

Prenatal weight gain

A healthy weight gain in first trimester should be between 3 to 4 lbs, gaining approximately one pound per week. A further 12 to 14 should be gained in second trimester, making the total weight gained around 14 to 16 pounds at the end of second trimester.

Continue to gain about a pound per week for the rest of the pregnancy should reach a total of 20 pounds towards the end. Weight gained between 20 to 30 pounds is perfectly healthy and normal. It is impossible to control your prenatal weight gain precisely, but between this range should be ideal for an average woman. An underweight mother could gain more and an overweight one should be more cautious.
