This week, we examine how dopamine affects horses with PPID.

There is a significant link between dopamine, diet, lifestyle, nutrition, and the symptoms commonly associated with PPID. So today, I share various lifestyle and nutritional ways horse owners can support dopamine levels in their horses.

Dopamine is a neurotransmitter responsible for motor skills, cognitive abilities, and the reward system, so it is vital for physical and mental health. Low dopamine levels in horses can lead to lethargy, depression, and poor concentration.

Dopamine plays a significant role in the reward system, and it also controls the overproduction of hormones like ACTH. When dopamine-producing brain cells degenerate, ACTH levels rise, leading to overworked pituitary glands and inflammation.

Stress and lifestyle factors can significantly impact dopamine levels in horses with PPID. Dopamine plays a crucial role in mood regulation, motivation, and overall well-being, so when horses are chronically stressed or have frequent inflammation, dopamine levels can drop. By addressing environmental stressors, changing diet, and providing a stable environment, owners can improve the dopamine levels of their horses.

Toxic hindgut conditions, often caused by poor diet and lack of movement, can negatively impact the microbiome of horses, leading to lower dopamine and serotonin levels. Unhealthy gut conditions also contribute to metabolic issues and hormonal imbalances, which can complicate health issues.

Connection Between Dopamine, ACTH, Cortisol, and Insulin

There is a relationship between dopamine, ACTH, cortisol, and insulin levels. Low dopamine leads to higher ACTH and cortisol levels, which increases blood sugar and insulin production. That imbalance is particularly problematic for horses with conditions like laminitis, so early intervention is essential to prevent further deterioration.

Managing conditions like PPID requires a holistic approach that focuses on diet, lifestyle, and mental and emotional health. As there is no quick fix for those chronic conditions, consistent management practices are essential for preventing disease progression and supporting horse health.

Maintaining dopamine levels through lifestyle changes and reward-based training is crucial. By engaging their horses in learning and activities that stimulate dopamine production, owners can help preserve their brain cell integrity and potentially slow the progression of PPID.

This week, we focus on Cushing syndrome, now known as PPID.

There is currently an epidemic of horses being diagnosed with this issue. It is a complex condition involving much chemistry and many hormones. So, I will continue exploring it in the next few episodes.

Even though the term Cushing's Syndrome in the horse health industry recently transitioned to Pituitary Pars Intermedia Dysfunction (PPID), I still prefer referring to it as Cushing's Syndrome, as that term encompasses the complexity of the condition, which involves multiple glands, not just the pituitary gland.

Cushing’s Syndrome might be defined more accurately as a hormonal imbalance rather than a pituitary issue. It is a complex condition involving many hormones and bodily systems, and many believe that underlying factors such as diet and lifestyle contribute to it, as it cannot be due to random occurrences.

Stress and inflammation are the key contributors to developing PPID or Cushing's Syndrome. When overstimulated due to stress or inflammation, the pituitary gland produces ACTH, leading to an overproduction of cortisol by the adrenal glands. That hormonal imbalance can lead to various health issues in horses over time.

In advanced stages of PPID or Cushing's Syndrome, a growth known as an adenoma may develop on the pituitary gland, which complicates treatment. Addressing the underlying causes, like diet and lifestyle, can sometimes reverse early-stage symptoms and reduce ACTH levels.

A multi-faceted, individualized approach is essential for treating horses with PPID or Cushing's Syndrome. Since symptoms, conditions, and history of horses vary, a one-size-fits-all treatment is ineffective. For that reason, customizing programs to the individual horse is crucial for managing the condition.

Horses with PPID often exhibit symptoms related to hormonal imbalances, like changes in shedding patterns, hair coat, excessive sweating, and fatigue. The symptoms can vary from horse to horse, making it essential to assess each case individually.

PPID affects the metabolism of horses, often leading to weight gain or loss, depending on the stage of the condition. The immune system also gets compromised, making horses more susceptible to infections and other health issues. Long-term elevated cortisol levels can cause muscle wasting and a weakened immune response.

Diet plays a significant role in managing PPID, as there is a link between sugar and inflammation in the condition. It is crucial to ensure that horses receive proper nutrition without any inflammatory ingredients. Monitoring and adjusting diet based on individual needs can help manage symptoms and improve overall health.

Managing PPID in horses requires a holistic approach that considers the complexity of the condition. By addressing underlying factors such as stress, inflammation, diet, and lifestyle, horse owners can help regulate hormonal imbalances and improve the quality of life of their horses.

This week, we are exploring sweet itch, also known as summer eczema.

This condition usually affects horses with hypersensitivity to insect bites and often occurs from bites from flies, mosquitoes, and especially biting midges, commonly called no-see-ums.

The occurrence and severity of sweet itch largely depend on environmental factors and the individual immune system of each horse.

Black horses and those with weakened immunity are more susceptible to sweet itch. Bugs target weaker horses, causing severe allergic reactions. Those reactions manifest as itching, rubbing, and discomfort, often leading to hair loss, sores, and bleeding. The immune response to these bites results in inflammation and welts, similar to how mosquito bites affect humans.

Diet and environmental factors significantly influence the susceptibility of each horse to sweet itch, and the condition can become exacerbated by high sugar intake, inappropriate grains, and poor-quality fats. Horses with compromised immune systems due to ulcers, metabolic issues, or nutrient deficiencies are more prone to severe reactions.

The acid mantle is a protective layer of the skin. It is crucial in defending against insect bites and infections. However, it can get damaged by a poor diet and toxins.

A holistic approach to managing sweet itch involves strengthening the immune system and overall health. That includes addressing underlying conditions such as ulcers, metabolic issues, and nutrient deficiencies. Natural remedies, dietary adjustments, and supportive supplements play a vital role. An example is vitamin C, which supports the immune system and helps maintain skin health.

Natural fly sprays and topical applications, like Riva's Herbal Skin Oil, can relieve itching and prevent infections. Holistic treatments, such as the Summer Tincture containing calendula, echinacea, linden, and milk thistle, help neutralize allergic reactions and support overall immune health. When you combine the use of those remedies with a clean diet and toxin elimination, it can significantly improve the condition of your horse.

Sweet itch is a challenging condition that requires a comprehensive approach to manage effectively. By addressing diet, immune health, and environmental factors, horse owners can help their horses overcome this uncomfortable ailment. Natural remedies and supportive supplements can offer significant relief and lead to long-term health.
