GI/Colic

Maintaining a healthy equine gastrointestinal (GI) system is essential for performance, longevity, and overall well-being. Colic remains one of the most common and serious equine emergencies, yet change to and ongoing research continues to improve our understanding of its causes, prevention, and treatment. From optimizing feeding practices and managing gastric ulcers to identifying risk factors for impaction, gas, or displacement colic, effective digestive care can make a measurable difference in every horse’s health and comfort.

This section explores the latest evidence-based approaches to colic prevention, diagnosis, and recovery, including advances in medical treatment, such as prokinetic medications and fluid therapy, as well as surgical care, including minimally invasive surgical techniques. You’ll also find insights on hindgut health, feed management, and microbiome balance, along with practical strategies to support intestinal motility and reduce stress-related digestive issues in performance horses.

Because equine digestion is closely connected to other systems—including dental health, immune function, and pain management—our coverage highlights a whole-horse approach to GI care. Explore the articles below to discover how veterinarians and nutritionists are applying science-driven solutions to minimize colic risk and promote optimal digestive health in horses.

Frequently Asked GI/Colic Questions

What are the main causes of colic in horses?

Common contributors include gas accumulation, impaction, feed changes, dehydration, sand ingestion, and management stressors. Individual risk varies with diet, dental status, parasite control, and housing; early veterinary assessment is critical to prevent progression.

How can diet changes reduce colic risk?

Gradual transitions, consistent forage access, and adequate water intake stabilize the hindgut and reduce motility disturbances. Frequent small meals and attention to electrolyte balance are especially important for performance horses with high workloads.

When should omeprazole be used for gastric ulcers?

Omeprazole is used under veterinary guidance for diagnosed or strongly suspected equine gastric ulcer syndrome, particularly in training or competition horses. Treatment plans consider dose, duration, tapering strategy (if any), and concurrent management changes such as feeding and turnout.

What is metoclopramide’s role in delayed gastric emptying?

As a prokinetic, metoclopramide may be used in select cases to stimulate upper GI motility and aid gastric emptying. Use is case‑dependent and should follow diagnostic evaluation and monitoring for efficacy and adverse effects.

Which management practices help prevent recurrent colic?

Provide frequent small meals, maximize turnout, maintain regular exercise, and schedule routine dental exams. Consistent routines, appropriate parasite control, and careful re‑feeding after illness help reduce recurrence.

Do feed additives and probiotics help equine gut health?

Evidence suggests certain probiotics, prebiotics, and fiber sources can support hindgut balance and barrier function. Product selection and dosing should be tailored with veterinary input to the horse’s diet, workload, and clinical history.
