Management options for IBS

Successful IBS management
relies on a strong patient and
healthcare provider relationship. 

Clinical care pathway

Management strategies for IBS may include lifestyle and dietary changes, over-the-counter medications, and prescription medications.1,2 Successful management of IBS involves an individualized treatment approach by working closely with patients over time to better understand the patients’ characteristic symptoms and needs, provide education, and identify the most suitable treatment plan together.1-3 Below are some key steps that may help guide effective long-term management of IBS. 

Patient Education AND Shared Decision-Making

The overall goal should be to develop a mutually agreeable management plan with realistic expectations.4 Encourage patients to lead discussions through patient-centered interviewing regarding their experiences, worries, preferences, and expectations. 

You can provide education regarding the causes and natural history of IBS.3 Shared decision making is distinct from and goes beyond patient education or the provision of informed consent in that it is bidirectional communication wherein the patient gains insight into treatment options and the clinician gains an appreciation for what matters to the patient. This can be reassuring to the patient and help improve outcomes.4-8 

Be sure to inform patients regarding common points of concern:

  • Symptoms are not life-threatening; focusing on creating a treatment plan to alleviate symptoms can provide optimism for patients that IBS can be successfully managed3,9
  • There is no increased risk of cancer in patients with IBS; careful explanations of the nature of the disease will help reduce fears3
  • There is no direct “cure” for IBS; reassurance and explanation of the disease course are vital3

Lifestyle AND diet

Encourage your patients to practice healthy habits, such as:3

  • Regular exercise, e.g., a 20-minute walk each day3
  • Good sleep hygiene, e.g., having a period of time for relaxation before going to bed, avoiding food or drinks with caffeine for at least 4 hours before bedtime, and refraining from viewing a TV screen before sleeping10
  • Healthy eating behavior, e.g., taking time over meals, sitting down to eat, and eating regularly11

Specialized diets, such as a low-FODMAP diet, may be an appropriate recommendation based on the patient’s history and symptoms.12-14 Consider if symptoms appear linked to specific “triggers,” and if so consider if reducing or avoiding these is appropriate. Common triggers include:15,16

Caffeine

Artificial sweeteners (e.g., diet candies and chewing gum)

Spicy foods

Legumes (e.g., beans and lentils)

Dairy products

High-fiber foods

Psychosocial considerations

Anxiety, depression, and other psychological disorders may be present in some patients with IBS.17 Therefore, it is important to assess patient history and observe whether psychological issues are present.18,19 Anxiety in patients with IBS may also be symptom-related and stress reduction may be beneficial.20 The following relaxation techniques may be worth discussing with your patients based on their symptom history:20

  • Meditation
  • Deep breathing
  • Yoga

The pathophysiology of IBS is multifactorial, and personalized approaches based on IBS severity, most bothersome symptom(s), and factors that drive symptom experience are critical to effective care. Gut-directed psychotherapies (GDPs), which as a class include cognitive-behavior therapy (CBT) and gut-directed hypnotherapy (GDH), improve IBS symptom severity by targeting the cognitive and affective factors known to drive symptom experience. Cognitive and affective states are driven by the emotional centers of the brain and determine how input from the gut is perceived, interpreted, and regulated.21

Examples of cognitive-affective factors that negatively impact IBS are fear of symptoms, pain catastrophizing, attentional bias/hypervigilance, somatization, and stress sensitivity. GDPs are less effective in patients with comorbid mental health conditions; these patients should be referred to non-GI mental health professionals for care.21

Pharmacological management

Pharmacological interventions are often important and potentially necessary along with dietary and lifestyle changes.3 Treatments should be tailored to the individual patient and take into account the severity of the disease (mild, moderate, or severe), which is typically assessed subjectively in practice based on frequency of symptoms and impact of symptoms on patients’ daily lives.22 Over-the-counter medications that target specific symptoms, such as laxatives, antidiarrheals, or antispasmodics, may be appropriate for patients with mild IBS symptoms, and can often be used on an as-needed basis.3

Other pharmacological options for treatment of IBS can be considered depending on the patient’s history and symptoms.3

Reassessment

IBS management is an ongoing process. It is important to work with patients by providing information on lifestyle, diet, and pharmacological options to ultimately improve their quality of life.22 A regular follow-up should be conducted to assess patient progress, depending on the patient’s personal and symptom history.22 If patient symptoms are not improving, additional or alternative treatment options should be considered.22

Linaclotide Indications and Safety25

Linaclotide is a guanylate cyclase-C agonist indicated for the treatment of:

  • Irritable bowel syndrome with constipation (IBS-C) in adults
  • Chronic idiopathic constipation (CIC) in adults
  • Functional constipation (FC) in pediatric patients 6 to 17 years of age

WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS LESS THAN 2 YEARS OF AGE

Linaclotide is contraindicated in patients less than 2 years of age; in non-clinical studies in neonatal mice, administration of a single, clinically relevant adult oral dose of linaclotide caused deaths due to dehydration.

Contraindications

Linaclotide is contraindicated in patients:

  • Less than 2 years of age due to the risk of serious dehydration
  • With known or suspected mechanical gastrointestinal obstruction

Warnings and Precautions

Risk of Serious Dehydration in Pediatric Patients Less Than 2 Years of Age: Linaclotide is contraindicated in patients less than 2 years of age. The safety and effectiveness of linaclotide in patients with FC less than 6 years of age or in patients with IBS-C less than 18 years of age have not been established.

Diarrhea: In adults, diarrhea was the most common adverse reaction in linaclotide-treated patients in pooled IBS-C and pooled CIC double-blind placebo-controlled trials. In a double-blind placebo-controlled trial in pediatric patients 6 to 17 years of age with FC treated with linaclotide, diarrhea was the most common adverse reaction. If severe diarrhea occurs, dosing should be suspended, and the patient rehydrated.

Common Adverse Reactions (incidence ≥2% and greater than placebo)

  • In IBS-C clinical trials (in adults): diarrhea (20% vs 3% placebo), abdominal pain (7% vs 5%), flatulence (4% vs 2%), headache (4% vs 3%), viral gastroenteritis (3% vs 1%) and abdominal distension (2% vs 1%).
  • In CIC trials of a 145 mcg dose (in adults): diarrhea (16% vs 5% placebo), abdominal pain (7% vs 6%), flatulence (6% vs 5%), upper respiratory tract infection (5% vs 4%), sinusitis (3% vs 2%) and abdominal distension (3% vs 2%).
  • In a CIC trial of a 72 mcg dose (in adults): diarrhea (19% vs 7% placebo) and abdominal distension (2% vs <1%).
  • In a FC trial (in pediatric patients age 6 to 17 years): diarrhea (4% vs 2% placebo).
