Understanding Functional and Refractory Constipation and the Role of Physiotherapy

Constipation is a common gastrointestinal problem affecting people of all ages, characterized by infrequent, difficult, or incomplete bowel movements. It can significantly impact quality of life, causing discomfort, bloating, and fatigue. Broadly, constipation is classified into functional (primary) and refractory (resistant) types, each requiring tailored management strategies.

What is Functional Constipation?

Functional constipation is a diagnosis given when bowel habits are abnormal but no underlying structural or biochemical cause is identified. It is often related to lifestyle factors such as inadequate fibre intake, dehydration, sedentary lifestyle, or ignoring the urge to defecate.

Functional constipation includes symptoms such as infrequent bowel movements (less than three per week), hard stools, straining, a sensation of incomplete emptying, and the absence of underlying disease.

What is Refractory Constipation?

Refractory constipation refers to cases where usual treatments (dietary modifications, laxatives, or behavioural interventions) fail to provide relief. This form may involve complex anatomical, neurological, or motility disorders and often requires a comprehensive and multidisciplinary approach.

Role of Physiotherapy in Managing Constipation

Specialist Physiotherapy is an effective strategy in managing both functional and refractory constipation, especially through pelvic floor muscle training (PFMT), biofeedback therapy, and lifestyle modifications.

1. Pelvic Floor Muscle Assessment and Specific Training : This involves comprehensive assessment of an individual's pelvic floor and sphincter muscles. Following this, specific exercises are given to coordinate the pelvic floor muscles to aid effective bowel evacuation. Proper technique can reduce straining and improve symptoms.

2. Biofeedback Therapy : A specialised physiotherapy approach that uses visual or tactile feedback to help individuals learn how to control and improve pelvic floor muscle function. It is particularly beneficial in cases of pelvic floor dyssynergia, where muscle coordination is dysfunctional.

3. Postural and Breathing Exercises:These can enhance diaphragmatic breathing and abdominal muscle function, which support bowel movements.

Additional Physiotherapy Tips

• Bladder and bowel training: Establishing regular toileting routines.

• Education: Teaching proper toileting posture (e.g., squatting position or footstools to elevate the feet).

• Lifestyle modifications: Encouraging increased physical activity to stimulate bowel motility.
