Can anxiety with GAD-7 score of 14 worsen my IBS-D symptoms?

Question

Hello doctor,

I am a 37-year-old female diagnosed with irritable bowel syndrome (IBS) three years ago, predominantly the IBS-D type. I have frequent loose stools four to five times a day, especially after meals, along with abdominal cramping, bloating, and occasional urgency.

My recent stool tests were negative for infection, and the colonoscopy six months ago was normal. I also have had generalized anxiety disorder for the past five years, with my last GAD-7 score at 14, indicating moderate anxiety. My BMI is 23.6 kg/m², blood pressure averages 116/74 mmHg, and fasting blood sugar is 92 mg/dL.

I am currently taking Dicyclomine 10 mg as needed for cramps and Escitalopram 10 mg daily for anxiety. I avoid dairy and high-fat foods, which worsen my symptoms, and I drink around 67.628 ounces of water daily. My vitamin D level is 20 ng/mL, and my hemoglobin is 11.4 g/dL. I do not smoke or drink alcohol.

I am concerned that my anxiety is making my IBS worse and that flare-ups are affecting my work and social life. I would like to know if gut-directed therapies, probiotics, or dietary plans like the low-FODMAP diet could help manage both my IBS and anxiety effectively.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

Your symptoms suggest that both your IBS-D (irritable bowel syndrome with diarrhea, a chronic gastrointestinal disorder marked by frequent, loose, or watery stools, along with abdominal pain, cramping, and urgency) and anxiety are contributing significantly to your quality of life. It is very common for stress and anxiety to worsen IBS flares through the gut–brain axis.

Since your colonoscopy and stool tests were normal, management focuses on symptom control and lifestyle adjustments.

Gut-directed therapies such as cognitive behavioral therapy (CBT) and gut-directed hypnotherapy have been shown to improve both IBS symptoms and anxiety by addressing this gut-brain connection.
Dietary strategies, particularly the low-FODMAP diet (a three-phase, short-term eating plan for two to six weeks designed to identify food triggers for IBS and digestive issues by eliminating, then systematically reintroducing, fermentable carbohydrates), can be highly effective in reducing bloating, cramping, and diarrhea, though it is best done with guidance from a dietitian to avoid unnecessary restrictions.
Probiotics may also help regulate gut microbiota and reduce IBS (irritable bowel syndrome) symptoms, though responses vary depending on the strain.
Since your vitamin D is low and your hemoglobin suggests mild anemia (a common condition characterized by a slightly low red blood cell count, often causing no symptoms or minor fatigue, weakness, and dizziness), supplementation and further evaluation of iron status would also be beneficial.
Overall, a combined approach continuing your current anxiety treatment with Escitalopram, adding structured dietary management like low-FODMAP, considering probiotics, and exploring gut-directed psychological therapies offers the best chance of improving both your IBS and anxiety together.

I hope this answers your query.
