Hello loneskate, Thank you for your question regarding the potential link between diastasis recti and fluid retention. Diastasis Recti and Fluid Retention: Diastasis recti, a condition where the abdominal muscles separate, can indeed create a noticeable gap in the abdominal wall. However, this condition is not directly known to cause fluid retention. Here are some points to consider: Interstitial Space: Diastasis recti may increase the interstitial space in the abdominal region, but this space is primarily occupied by tissues and organs. The increased space itself is unlikely to cause significant fluid retention. Causes of Fluid Retention: Fluid retention, or edema, can be caused by various factors, including heart, liver, or kidney issues, as well as certain medications and hormonal imbalances. Since you mentioned that no medical exams found anything amiss and diuretics were not advised, it is less likely that your fluid retention is directly related to diastasis recti. Abdominal Surgery and Fluid Retention: Surgeries, including laparoscopic hernia repairs, can sometimes lead to temporary fluid retention due to the body's response to trauma. However, long-term retention from such procedures is uncommon. Considering a Tummy Tuck: A tummy tuck (abdominoplasty) involves repairing diastasis recti by suturing the separated muscles together, which can restore abdominal integrity and potentially improve core stability and appearance. While this procedure can address the muscle separation, it is not primarily aimed at resolving fluid retention. Next Steps: Consult a Specialist: Before proceeding with any surgery, it is essential to consult with a board-certified plastic surgeon who has experience in treating diastasis recti. They can provide a thorough evaluation and discuss whether a tummy tuck is appropriate for your condition. Medical Evaluation: Since fluid retention can have multiple causes, it is crucial to continue working with your healthcare providers to monitor and manage your symptoms. Ensure all potential underlying causes have been thoroughly investigated. Consider All Options: Surgery is one option for treating diastasis recti, but there may be non-surgical approaches, such as physical therapy, that can also provide relief and improve muscle function. Conclusion: While diastasis recti may contribute to changes in abdominal structure, it is unlikely to be the primary cause of significant fluid retention. A comprehensive medical evaluation and consultation with a plastic surgeon will help determine the best course of action for your specific situation. Good luck, and I hope this helps to answer your question regarding diastasis recti and fluid retention. Sincerely, J. Timothy Katzen, MD, FASMBS, FICS Plastic Surgeon
