Being at an ideal weight for a healthy pregnancy is important for both maternal and infant health. Obesity is a significant factor that increases the risk of gestational diabetes, hypertension, and preeclampsia during pregnancy.
In this guide, we answer the questions that those planning a pregnancy frequently ask about the Allurion Program.
1. Can a Gastric Balloon Be Placed During Pregnancy?
No. The Allurion Balloon and all swallowable gastric balloons are contraindicated during pregnancy. This is a clear red line.
If pregnancy is detected:
- The balloon (if it is still in the stomach) is removed immediately.
- The program is stopped.
For this reason, a pregnancy test before starting the Allurion Program is part of the routine protocol.
2. Can a Gastric Balloon Be Done Before Planning a Pregnancy?
Yes, when the timing is planned correctly. General guidance:
- The Allurion Balloon passes naturally at around week 16 (the 4th month).
- The program lasts 6 months.
- After the program is completed, pregnancy can be planned once you have waited at least 3–6 months and reached a stable weight.
Recommended minimum time: 6 months after the end of the program.
Your clinician makes this decision through an individual assessment.
3. Benefits of Weight Loss for Pregnancy
In Ienca et al.'s study of 1,770 patients, a mean total body weight loss of 14.9% was documented (Obes Surg 2020, PMID: 32279182). A weight loss at this level:
- Reduces the risk of gestational diabetes
- Lowers the likelihood of hypertension
- Reduces birth complications
- Lowers the risk of macrosomia (excessive growth) in the baby
4. Long-Term Weight Maintenance
In Caballero et al.'s study of 522 patients, 95% of patients were shown to maintain part of their weight loss at the first year after the program (Obes Surg 2025, PMID: 40676353).
This is important for pre-pregnancy planning: the sustainability of weight loss brings pregnancy into a safe window.
5. Frequently Asked Questions
Can the balloon be placed during breastfeeding? No. The breastfeeding period is also within the scope of contraindication.
Does a gastric balloon affect fertility? No, the balloon itself does not affect the reproductive system. It is known that weight loss may positively influence hormonal balance.
What happens if weight is regained after the program? Pregnancy should not be planned before the program is completed. Pregnancy carries increased risk if weight is not stable.
Conclusion
The Allurion Program can be an effective option for pre-pregnancy weight management. The critical point: complete the program at least 6–12 months before planning a pregnancy and keep your weight stable.
