what is Early weight gain is mainly?

Early weight gain primarily refers to the initial increase in weight that occurs during pregnancy, typically in the first trimester. This gain is mainly due to factors such as the growth of the fetus, increased blood volume, and the accumulation of bodily fluids and tissues.

It is an important aspect of a healthy pregnancy, as it supports fetal development and prepares the mother's body for childbirth.
