At Hatch Fertility, we recognize that qualifying to become a surrogate involves several nuances that can create hesitation for those looking to help a family. An important and frequently discussed qualification is maintaining a healthy Body Mass Index (BMI). In this blog, we’ll explore why BMI is a key factor in surrogacy, shedding light on the implications of high and low BMI and providing clarity on how it impacts the health and safety of both the surrogate and the baby. We hope this article offers understanding for this qualifying factor and helps you feel more confident in your surrogacy journey.

What is BMI?

Body Mass Index (BMI) is a commonly used measure to assess whether a person has a healthy body weight for a given height. It’s calculated by dividing a person’s weight in kilograms by their height in meters squared. This simple formula gives a number that categorizes individuals into underweight, normal weight, overweight, or obese categories, helping healthcare professionals evaluate weight-related health risks.

However, BMI has its limitations. It doesn’t differentiate between muscle mass and body fat, meaning that muscular individuals might be classified as overweight or obese despite having a healthy body composition. Additionally, BMI doesn’t account for fat distribution, which is an important factor in assessing health risks—central or visceral fat is more closely linked to conditions like heart disease and diabetes than fat located in other areas.

While BMI can be a useful tool in a clinical setting, it’s important to consider its limitations and look at it as one piece of the overall health puzzle. For a more precise evaluation, other measurements and factors should be taken into account.

In the context of surrogacy, BMI is considered to ensure the health and safety of both the surrogate and the baby. A healthy BMI range can reduce the risks associated with pregnancy and delivery, providing the best possible outcome for all parties involved. Calculate your BMI, and remember, it’s always best to discuss your results with a healthcare professional for a comprehensive assessment.

What is a "Healthy" BMI?

While BMI is a helpful tool for assessing body weight in relation to height, it should not be seen as an official representation of overall health. It’s just one piece of the health puzzle and doesn't account for factors such as muscle mass or fat distribution as we previously mentioned.

Here are the standard BMI ranges:

  • Underweight: BMI less than 18.5
  • "Healthy Weight: BMI between 18.5 and 24.9
  • Overweight: BMI between 25 and 29.9
  • Obese: BMI of 30 or higher

A “healthy” BMI range is generally associated with lower health risks, but it’s crucial to consider other aspects of health and well-being. Factors such as physical fitness, diet, and overall lifestyle also play significant roles in determining true health. 

BMI Requirements for Surrogates

At Hatch Fertility, one common question we receive is: "Why is BMI so important for surrogates?" Our BMI range for surrogates is no higher than 32. This requirement ensures the health and safety of both the surrogate and the baby. It’s important to note that this requirement can vary from agency to agency. However, given our high success rate, we've found this range to be highly effective.

BMI matters for surrogates because it impacts the success of the medications necessary for IVF and the embryo transfer. Maintaining a healthy BMI range can minimize risks of complications during pregnancy and delivery, providing the best possible outcome for all parties involved. Ensuring a surrogate’s health is paramount, as it directly affects the overall success and well-being of the surrogacy journey.

Understanding these requirements helps in assessing eligibility and planning the journey ahead. Next, we’ll delve into the potential surrogacy disqualifications related to both high and low BMI. We’ll shed light on the specific risks involved and how these factors are crucial to ensuring a safe and healthy experience for everyone. 

High BMI Surrogacy Risks

High BMI can lead to complications and various health issues during pregnancy. These risks are not limited to the following:

  • Preeclampsia
  • Gestational diabetes
  • Gestational hypertension
  • Macrosomia (having a larger-than-average baby)
  • Increased risk of cesarean delivery
  • Sleep apnea
  • Higher chances of miscarriage
  • Postpartum hemorrhage

Understanding these risks highlights the importance of maintaining a healthy BMI to ensure the safety and well-being of both the surrogate and the baby. Next, we’ll explore the potential risks associated with low BMI in surrogacy.

Low BMI Surrogacy Risks

Low BMI can also lead to complications and health issues during pregnancy. These risks include, but are not limited to:

  • Premature birth
  • Low birth weight
  • Fetal growth restriction
  • Developmental issues
  • Increased risk of miscarriage
  • Nutritional deficiencies
  • Anemia

Maintaining a healthy BMI is essential to minimize these risks and ensure the well-being of both the surrogate and the baby. Understanding the implications of both high and low BMI helps provide a safer and healthier surrogacy journey.
