Step on the accelerator: modern treatment of constipation

Abstract

Purpose of review This review aims to explore effective management of constipation, examine challenges in making a positive diagnosis, and highlights the significance of a positive patient-provider relationship and emerging treatments. Recent findings Less than one-fifth of patients feel satisfied with treatment of their constipation. Sixty percent of patients with functional dyspepsia and gastroparesis have severe to very severe constipation that correlates with their upper gastrointestinal symptom severity. Two gold kiwifruits are noninferior to 10 g of psyllium in the treatment of constipation. More than 40% of patients undergoing lumbar fusion continue to fill opioid prescriptions 90 days after surgery, contributing to 80 000 chronic opioid users annually. Most patients are using over-the-counter (OTC) treatments for constipation with greater than 60% dissatisfied. Pharmacologic management involves the use of GCC agonists and emerging drug classes such as bile acid transport inhibitors and sodium hydrogen exchanger isoform 3 (NHE3) inhibitors. Nonpharmacologic treatments, including neuromodulation and FDA-approved vibrating capsule, show promise in improving symptoms and quality of life. Summary Constipation significantly impacts patients’ quality of life and well being and the majority of patients are refractory to conservative measures and OTC treatments. Both pharmacologic and nonpharmacologic treatments hold promise for improving constipation and quality of life.
