Does IVF in the US and Mexico Cause Weight Gain? Understanding Real Body Changes During Preconception

With the growing popularity of assisted reproductive technologies, IVF and egg freezing in the US and Mexico have become choices for many families. A common question among women preparing for pregnancy is whether IVF will lead to weight gain. In reality, changes in body weight are not solely caused by the IVF process itself but are influenced by hormones, diet, psychological factors, and other variables.

 

Before starting the IVF cycle, women typically enter the ovarian stimulation phase. To encourage the ovaries to produce multiple mature eggs simultaneously, doctors create hormone protocols tailored to each individual. Some women may experience mild bloating or temporary weight gain during this phase, primarily due to water retention rather than fat accumulation. Once the medication is discontinued, weight usually returns to normal.

 

The egg retrieval and embryo transfer stages are often the periods when body weight concerns are most pronounced. Some patients, worried about embryo implantation failure, may reduce physical activity or increase intake of high-calorie foods, causing an imbalance between energy intake and expenditure. While this “protective weight gain” may make sense psychologically, medically it is recommended to maintain regular routines and balanced nutrition for optimal embryo development.

 

If pregnancy is achieved, weight gain naturally follows. This is a normal response to pregnancy and not unique to IVF. Doctors generally advise controlling early pregnancy weight gain to avoid issues such as elevated blood sugar or blood pressure. Adequate protein and vitamin intake, along with moderate exercise, help the body adapt to pregnancy changes more smoothly.

 

US and Mexican fertility clinics emphasize individualized care. During the IVF process, doctors assess each woman’s basal metabolism, hormone levels, and lifestyle to provide tailored medication and nutrition guidance. Scientific monitoring and precise management help minimize unnecessary side effects, keeping the body in the best condition during preconception.

 

For women planning egg freezing, the situation is similar. Short-term hormone stimulation may cause slight bloating but does not have a significant long-term effect on body weight. Egg freezing allows women to preserve high-quality eggs while young, providing greater flexibility for future family planning and serving as a scientific approach to fertility management.

Dr. Nathan Zhang’s IVF USA team has provided overseas assisted reproductive consulting for over a decade, offering US egg freezing, US IVF, and third-party reproduction services. With nearly 20 years of expertise in international reproductive medicine, IVF USA has established a presence in Mexico as the Chinese representative for Power Fertility Center (POWER IVF) and expanded services to Japan, Thailand, Taiwan, and Hong Kong. In a more scientifically guided era of fertility, each choice opens the door to more possibilities for the future.
