Can hormones worsen IBS during fertility treatment?

Question

Hi doctor,

My 33-year-old wife was diagnosed with IBS six years ago, and her symptoms have worsened significantly since we started trying to have a baby.

She experiences severe abdominal cramping, bloating, and alternates between constipation and diarrhea. We have consulted three gastroenterologists and tried the low FODMAP diet, which provided some relief but is too restrictive for her to maintain long-term.

Her symptoms become especially severe right before her period; during the week leading up to menstruation, she can barely leave the bathroom. We have tried peppermint oil, probiotics, and fiber supplements, but nothing seems to provide lasting relief.

Her IBS is also impacting her fertility treatments, as she feels very uncomfortable during ovulation. Recently, she had an HSG test as part of her fertility workup, which showed that her tubes are open. However, the procedure triggered an IBS flare-up that lasted for two weeks.

Her gynecologist believes that the stress from infertility may be exacerbating her IBS symptoms. While antispasmodics like Dicyclomine help with cramping, they make her too drowsy. We are wondering if hormonal changes could trigger IBS symptoms as well.

We really need better management for her condition, as it is affecting our attempts to conceive.

Please help.

Hi,

Welcome to icliniq.com.

I am genuinely concerned about your worries.

I am really sorry that you and your wife are facing this challenge. Dealing with IBS (irritable bowel syndrome), along with the emotional and physical strain of trying to conceive, can be incredibly overwhelming and feel deeply unfair.

It is completely understandable that both of you are feeling exhausted. Hormones can definitely trigger and worsen IBS symptoms. Many women notice their symptoms flare up during the week before their period when fluctuations in progesterone and estrogen affect gut motility and pain sensitivity.

During this time, the intestines can become more sensitive to stretching and gas, leading to cramping, bloating, and frequent, urgent bowel movements.

Additionally, stress plays a significant role through the gut-brain axis, meaning that fertility treatments, medical procedures like hysterosalpingogram (HSG), and the pressure of timing ovulation can exacerbate symptoms even if she is doing everything right.

This does not mean that her symptoms are psychological or imagined; rather, her gut is responding to genuine hormonal and nervous system signals. The good news is that IBS does not affect fertility itself, and better management of her symptoms can make this process more bearable. Since Dicyclomine causes too much drowsiness, there are other options to consider.

These may include lower doses of antispasmodics taken only during flare-ups, gut-targeted medications like Rifaximin for IBS with diarrhea, or low-dose neuromodulators like Amitriptyline or Nortriptyline at night, which can reduce gut pain sensitivity without acting as antidepressants.

Some women find relief by adjusting the type of fiber they consume rather than the amount, such as opting for soluble fiber like psyllium instead of mixed fibers.

Gentle pelvic floor physical therapy can also help, especially if bowel urgency and cramping are severe around ovulation or menstruation. Given that her symptoms worsen during her cycle, coordinating care between her gastroenterologist and gynecologist could help tailor treatments to address hormonal peaks, rather than relying on constant medication.

Most importantly, this is not a failure on her part, and it does not mean she cannot go on to have a healthy pregnancy. Many women with IBS do conceive, and symptoms can even improve once pregnancy hormones stabilize.

Right now, the priority is to help her feel more comfortable and supported during this challenging time, rather than trying to push through the pain.

With a more individualized treatment plan that acknowledges the hormonal component, there is genuine hope that her IBS can become more manageable while you continue your family-building journey.

If you have any more questions, feel free to ask. I would be happy to guide you. Please keep your valuable feedback for better patient care.

Thank you so much.
