What is the normal expectation for weight gain in the first trimester of pregnancy?

During the first trimester of pregnancy, the typical expectation for weight gain is between 1 to 5 pounds. This range is considered normal as many women experience minimal weight gain during this early stage. The reason for this modest gain is that the first trimester is primarily focused on supporting the initial development of the embryo and the body adjusting to pregnancy.

Additionally, hormonal changes, nausea, and other early pregnancy symptoms may affect appetite and food intake, leading to a smaller increase in weight compared to later trimesters. This weight gain is usually sufficient to support early fetal growth, and it provides a foundation for the increased energy needs during the subsequent months of pregnancy.

In contrast to this, choices indicating a greater weight gain within the first trimester do not align with typical physiological expectations or guidelines from health organizations regarding healthy pregnancy weight gain.
