How can my sister manage her IBS-D in the long-term?

Question

Hello doctor,

My sister is 30 and has been experiencing chronic diarrhea, abdominal cramping, and daily bloating. She was told it may be IBS-D, but she has not received a clear management plan. These symptoms are really affecting her work and social life, and she’s becoming increasingly anxious about eating out or traveling.

Could you advise whether there are effective long-term treatment options?
We are also wondering if her symptoms could be influenced by anxiety or hormonal cycles. She attempted the low-FODMAP diet but found it overwhelming to follow.
Could you please explain what typically causes IBS-D in women and what realistic options she has to better manage her symptoms?

She just wants to feel like herself again.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

Your sister seems to be having quite a tough time with IBS-D (irritable bowel syndrome with diarrhea), and it is no wonder you would seek more specific guidance in such a case. IBS-D is a chronic disorder that causes abnormal digestive symptoms between the gut and the brain, leading to symptoms such as chronic diarrhea, cramping, and bloating. Hormonal changes, especially around the menstrual cycle, can exacerbate symptoms in women. Anxiety and stress also play a notable role because of the close interconnection between the gut and the nervous system through the gut-brain axis.

While there is no single cure for IBS-D, effective management is absolutely possible, and treatment options have included dietary adjustments, medication, and stress management strategies. A low-FODMAP diet, which limits certain fermentable carbohydrates that trigger symptoms, has been especially helpful for many. If your sister finds this diet confusing, working with a dietitian experienced in IBS can make it much more manageable.

Medications can also be helpful, such as:

Antispasmodics like Dicyclomine to reduce cramping, Loperamide to help control diarrhea, and Rifaximin, a short-course antibiotic that may relieve symptoms by modifying gut bacteria. Newer options include those like Eluxadoline that target gut nerve function; low-dose tricyclic antidepressants, such as Amitriptyline, can reduce gut pain and urgency even when not used for mood.

If anxiety is contributing to her symptomatology, therapies like cognitive behavioral therapy (CBT) focused on IBS have very strong evidence of benefit. While IBS can be unpredictable, many people achieve good symptom control with the right combination of treatments.

She might need to see a gastroenterologist for a personalized plan and even a therapist if stress is a big trigger. IBS-D is quite genuine, and it is treatable; if she receives the right support, then she can regain her confidence and comfort in her daily life.

I hope this helps.

Kindly revert if there are any queries.

Thank you.
