Fall can be a challenging time for horses with metabolic issues, even when you’ve spent months doing everything right.
Today, we’re exploring five reasons metabolic horses struggle in the fall. You’ll learn how to recognize seasonal setbacks, track meaningful signs of improvement, and support your horse without abandoning a program that may still be working.
Metabolic horses
Shorter days trigger hormonal changes that prepare horses for winter. Rising ACTH and cortisol can increase blood sugar and insulin, promoting fat storage. Metabolic horses may also develop fat pads, retain fluid, and experience increased inflammation.
Fall grass
Sunny days followed by cold nights can cause sugars to accumulate in grass. Frost-stressed, short or brown grass may also be high in sugar, increasing risks for sensitive horses.
Dietary changes
Abruptly switching from grass to hay disrupts the hindgut microbiome and may contribute to inflammation and digestive problems. Instead, transition gradually over two to three weeks.
Inflammation
Digestive problems, unresolved hoof damage, and poor circulation can contribute to inflammation. Inflammation may increase insulin, while high insulin promotes fat storage. Fat deposits can further contribute to inflammation.
Stress
Feed restriction, prolonged isolation and confinement can all increase stress and cortisol levels, even when a horse shows no obvious signs of anxiety. Some horses become withdrawn and apathetic rather than restless or agitated. Supporting metabolic health therefore means looking beyond diet to the horse’s overall well-being, with particular attention to the three Fs: forage, freedom and friendship.
Setbacks
Horses with existing metabolic dysfunction or incompletely healed hooves are more vulnerable to seasonal changes. Temporary setbacks do not automatically mean your management plan has failed.
Keep track
Track the horse’s energy, comfort level, mobility, digestion, and social engagement alongside physical changes. Record symptoms and pain levels to establish a baseline and objectively measure the horse’s progress.
Hoof problems
Stronger digital pulses, reluctance to move, or changes in stance warrant prompt attention. Assess the horse’s hoof trim, circulation, existing pathologies, and provide nutritional support.
Hormone tests
ACTH and insulin levels naturally fluctuate with the seasons, making isolated test results difficult to interpret. Assess the results alongside seasonal reference ranges and also consider the horse’s clinical signs and, ideally, hormone measurements taken over time. A single elevated result during fall should not automatically trigger a diagnosis or a decision to begin lifelong medication, as treatment decisions require a more complete picture of the horse’s health.
Preparing for fall
Transition gradually to hay, obtain a hay analysis, monitor pasture after cold nights, and maintain appropriate hoof care. Address stress, nutrition, and any other potential contributors to metabolic dysfunction.
Root causes
Persistent problems despite careful sugar management may be due to stress, gut dysfunction, nutrient deficiencies, toxicity, or chronic hoof inflammation. Similar symptoms can have different underlying causes, so each horse requires an individualized approach.
Recovery takes time
Equine metabolic syndrome requires consistent, long-term management. Addressing the underlying causes may help reduce seasonal setbacks and improve recovery over time. My forthcoming course, Your Horse's Root Cause Reset for Equine Metabolic Syndrome, will focus on identifying these causes.
Takeaways
Fall setbacks are not necessarily evidence of failure. Owners need to understand seasonal changes, track meaningful improvements, and investigate the horse’s individual needs rather than reacting to isolated symptoms. Remember that no two horses are the same, so their management programs should always address each horse’s individual needs.
