As we move from summer to fall, and temperatures at night start to cool, subtle changes begin to occur in our horses. 

Shorter days trigger powerful hormonal shifts, often before we even notice. Those shifts play an essential role in the health of our horses- especially those with metabolic conditions.

Hormone Shifts and Metabolism

Seasonal hormone shifts influence how horses process sugar, maintain muscle, and manage inflammation. In fall, ACTH levels naturally rise, increasing cortisol to drive fat storage and coat growth in preparation for winter. When those hormones remain elevated for too long, however, problems like delayed shedding, thick coats, sweating, muscle loss, inflammation, and a higher risk of laminitis may emerge.

Fall as a High-Risk Season

Far more horses tend to experience metabolic flare-ups in the fall as it brings a dangerous mix of hormonal shifts, fat storage, and higher pasture sugar levels, all of which raise the risk for equine metabolic syndrome and PPID. As horses naturally conserve energy and build fat reserves before winter, insulin resistance also tends to worsen.

Testing and Diagnosis

A single test showing high ACTH in fall is not enough to diagnose PPID. As ACTH naturally rises seasonally, it is essential to use multiple test results, and get a complete health profile before deciding on lifelong medication. 

Insulin, Inflammation, and Weight

Insulin is fundamentally a fat-storage hormone. If it is high, horses cannot lose weight. Chronic inflammation from laminitis or hoof pathologies drives insulin even higher, and elevated cortisol keeps blood sugar high, locking horses into a state of fat storage. That combination often causes gain weight and soreness in the fall.

Diet and Forage Management

Careful forage management is the foundation of supporting metabolic horses. Prioritize low-sugar hay and limit access to rich pasture, especially during high-risk seasons, like fall. Slow feeders, soaking hay, and controlled turnout can all help regulate sugar intake. Consistency in diet not only stabilizes insulin and energy levels but also reduces the risk of flare-ups.

Lifestyle and Stress

Stress management is as important as diet. Horses need freedom to move, regular forage, and companionship to regulate their cortisol levels and maintain metabolic balance. Stalled or isolated horses, or horses with long gaps between feedings suffer higher stress levels, which compounds hormone problems, and no supplement can overcome the damage caused by chronic stress and inappropriate living conditions.

Long-Term Management

Consistency is essential. Progress may seem slow at times, but steady attention to low-sugar forage, regular exercise, and stress reduction leads to lasting improvements. Expect seasonal setbacks, but they will be temporary. Over time, consistent care helps horses rebuild their health and resilience.

Hormonal Considerations in Mares

Mares can be susceptible to seasonal hormonal shifts. Changes in daylight and hormone levels often affect their cycles, behavior, and comfort. For mares with metabolic issues, those fluctuations may add another layer of stress, making careful monitoring and consistent management even more essential.

This week, we are diving into skin problems with horses. 

Skin problems are hard to ignore. They are right in your face, so they grab your attention instantly. 

Types of Skin Problems in Horses

Skin issues range from dry, flaky skin to severe allergic reactions. Horses may suffer from hives, sweet itch, infections like rain rot or mud fever, and chronic itchy skin. These conditions may appear as sudden, alarming outbreaks or develop into persistent, long-term struggles.

Why Skin Problems Demand Attention

Unlike hidden health issues, skin problems are visible and alarming, often pushing owners to act quickly. Acute flare-ups can appear to be emergencies, and chronic flare-ups may frustrate owners when topical treatments and medications only provide temporary relief.

Beyond the Surface

The skin is an organ and part of the immune system. When reactions occur externally, it is a sign of deeper imbalances, such as inflammation, immune dysfunction, or a toxin overload that can also affect internal systems.

Digestive Problems

Digestive problems often correlate with skin flare-ups. Ulcers, leaky gut, and poor liver function can raise histamine levels, leading to hives, itching, and chronic skin irritation. When the liver and gut cannot properly eliminate toxins, issues frequently surface in the skin.

The Role of Histamines

Histamine release is a natural immune response that can cause symptoms like swelling, itching, and hives. Horses with gut issues often produce excess histamine, making them more prone to skin outbreaks. Treating your horse only with antihistamines can suppress symptoms, but that does not solve the root cause.

Diet and Allergens

Some feeds can trigger skin reactions. Allergies or intolerances (such as to alfalfa) may take years to appear as acute symptoms. Long-term toxic buildup from feed, medication, or supplements can overload detox pathways and weaken skin health.

Liver Health

The liver plays a central role in detoxification. Over time, medications, poor nutrition, or stress can overwhelm the liver, leading to chronic skin problems. Supporting liver health is the key to sustainable recovery.

Triggers

Hormone imbalances and stress can affect skin health. Stress-related cortisol and adrenaline spikes increase histamine production, sometimes also triggering ulcers and hives. Managing stress is critical for restoring balance.

Long-Term Solutions

Quick fixes rarely last. Holistic management focuses on supporting digestion, detox pathways, nutrient balance, and emotional well-being. Owners may need to experiment and make gradual adjustments to find lasting solutions.

Key Takeaways

Skin health reflects whole-body health. A methodical approach that addresses gut health, liver function, diet, hormones, and stress will lead to lasting improvements, whereas symptom-only treatments will keep horses stuck in recurring cycles.

The thyroid gland plays a crucial role in the metabolic health and overall vitality of horses, yet it is often overlooked or treated only when serious problems arise. 

Understanding the role of the thyroid gland and the factors that support or hinder it is the key to long-term equine wellness. Remember that supporting your horse’s health holistically always begins with their diet, lifestyle, and stress reduction.       

Recognizing Thyroid Imbalance

Changes in the coat are often the first visible sign of thyroid imbalance. Horses may develop coarse or dry hair, experience hair loss, shed slowly, or grow curly hair. Those changes are all tied to the thyroid and could overlap with pituitary dysfunction.

Metabolism and Temperature Regulation

Thyroid health strongly influences weight and temperature regulation. Horses may gain weight despite appropriate feed and exercise, or show cold intolerance by shivering when others remain comfortable. Those signs reflect compromised heat production and metabolic function.

Hormones and Reproductive Health

Hormones are interconnected, so a thyroid imbalance could also affect the cycling and overall reproductive health of mares. Disruption in one hormone system influences others, highlighting the importance of a holistic approach.

Behavior and Energy Levels

Thyroid imbalance could manifest as depression, fatigue, or anxiety. Horses may withdraw from herd interaction, appear less playful, or become unexpectedly reactive despite consistent training. Physiological health can drive behavioral changes that horse owners should never overlook.

Muscle Health and Mineral Balance

Muscle weakness is another possible sign of thyroid imbalance. Selenium deficiency can also present similarly, highlighting the importance of evaluating mineral balance in addition to glandular health. Minerals often influence multiple systems simultaneously.

Closing Thoughts

Thyroid function is complex because it interacts with the pituitary gland, reproductive hormones, metabolism, and mineral balance. Paying attention to any changes occurring in the hair, coat, weight, temperature tolerance, behavior, and muscle strength can provide practical clues to possible metabolic imbalance. When those signs are present, it is essential to seek the right help to explore whether thyroid health may be a contributing factor.
