Equine Infectious Pulmonary Hemorrhage (EIPH) is a critical and often misunderstood condition that affects the health and performance of horses. As a responsible horse owner or enthusiast, it is essential to understand the intricacies of EIPH, its causes, symptoms, diagnosis, and treatment options. This knowledge can help you identify the condition early, provide proper care, and improve the overall well-being of your equine companion.
What is EIPH in Horses?
EIPH, also known as “bleeding,” is a condition where horses experience internal bleeding in their lungs, leading to a range of symptoms that can impact their athletic performance and overall health. The condition is characterized by the presence of red blood cells in the lungs, which can be detected through a process called endoscopy.
Why is EIPH Important to Understand?
EIPH is a common condition that affects a significant number of horses, with studies suggesting that up to 50% of horses may experience some degree of bleeding during their lifetime. The condition can have a significant impact on a horse’s performance, and if left untreated, can lead to serious health complications. By understanding EIPH, horse owners and enthusiasts can take proactive steps to prevent, diagnose, and treat the condition, ultimately improving the health and well-being of their horses.

In this article, we will delve into the world of EIPH, exploring its causes, symptoms, diagnosis, and treatment options. We will also discuss the importance of understanding EIPH, its impact on horse health and performance, and provide valuable insights for horse owners and enthusiasts. By the end of this article, you will have a comprehensive understanding of EIPH and be better equipped to care for your horse.
What is EIPH in Horses?
EIPH, also known as Exercise-Induced Pulmonary Hemorrhage, is a condition that affects horses and is characterized by bleeding in the lungs during intense exercise. It is a common condition that affects performance horses, particularly those involved in high-intensity activities such as racing, endurance riding, and show jumping.
Causes of EIPH
The exact cause of EIPH is still not fully understood, but several factors are thought to contribute to its development. These include: (See Also: How Many Horses In The Us)
- Increased pressure in the lungs: During intense exercise, the pressure in the lungs increases, causing the blood vessels to stretch and become more permeable. This can lead to bleeding in the lungs.
- Inflammation and oxidative stress: Intense exercise can cause inflammation and oxidative stress in the lungs, leading to damage to the blood vessels and bleeding.
- Genetic predisposition: Some breeds, such as Thoroughbreds and Quarter Horses, are more prone to EIPH due to their genetic makeup.
- Environmental factors: Environmental factors such as high altitude, hot and humid weather, and poor air quality can contribute to the development of EIPH.
Signs and Symptoms of EIPH
The signs and symptoms of EIPH can vary in severity and may not always be immediately apparent. Common signs and symptoms include:
- Coughing and nasal discharge: Horses with EIPH may develop a cough and nasal discharge due to the presence of blood in the lungs.
- Shortness of breath and fatigue: Horses with EIPH may become short of breath and fatigued more easily due to the reduced oxygen-carrying capacity of the blood.
- Decreased performance: Horses with EIPH may experience a decline in performance, including reduced speed, endurance, and overall athletic ability.
- Epistaxis: In severe cases of EIPH, horses may experience epistaxis, or nosebleeds, due to the bleeding in the lungs.
Diagnosis of EIPH
Diagnosing EIPH can be challenging, as the signs and symptoms can be similar to those of other respiratory conditions. A veterinarian may use a combination of the following diagnostic tests to confirm a diagnosis of EIPH:
- Endoscopy: A flexible tube with a camera on the end is inserted through the horse’s nostrils to visualize the lungs and airways.
- Bronchoalveolar lavage: A procedure in which a small amount of fluid is inserted through the endoscope and then collected to examine for the presence of blood and other cells.
- Blood tests: Blood tests may be used to measure the levels of certain enzymes and proteins that are elevated in horses with EIPH.
- Imaging studies: Imaging studies such as radiographs (x-rays) and ultrasound may be used to visualize the lungs and airways.
Treatment and Management of EIPH
Treatment and management of EIPH typically involve a combination of the following:
- Rest and recuperation: Horses with EIPH should be given time to rest and recover to allow the lungs to heal.
- Medications: Medications such as furosemide (Lasix) may be used to reduce the pressure in the lungs and prevent further bleeding.
- Environmental changes: Environmental changes such as reducing the intensity of exercise, providing adequate ventilation, and using nasal strips to reduce nasal resistance may help reduce the severity of EIPH.
- Surgical intervention: In severe cases of EIPH, surgical intervention may be necessary to repair damaged blood vessels or remove blood clots.
Prevention of EIPH
Preventing EIPH involves a combination of the following:
- Gradual conditioning: Gradually increasing the intensity and duration of exercise can help reduce the risk of EIPH.
- Adequate warm-up and cool-down: Providing adequate warm-up and cool-down periods can help reduce the risk of EIPH.
- Proper nutrition and hydration: Ensuring that horses receive proper nutrition and hydration can help reduce the risk of EIPH.
- Regular veterinary care: Regular veterinary care and monitoring can help identify horses at risk of EIPH and prevent its development.
Complications of EIPH
If left untreated or poorly managed, EIPH can lead to several complications, including:
- Chronic bronchitis: Repeated episodes of EIPH can lead to chronic bronchitis, a condition characterized by inflammation and scarring of the airways.
- Pulmonary fibrosis: EIPH can lead to pulmonary fibrosis, a condition characterized by scarring of the lung tissue.
- Respiratory failure: In severe cases of EIPH, respiratory failure can occur, leading to a life-threatening condition.
Conclusion
EIPH is a common condition that affects performance horses, particularly those involved in high-intensity activities. While the exact cause of EIPH is still not fully understood, several factors are thought to contribute to its development. Early diagnosis and treatment are critical in managing EIPH, and preventing its complications. By understanding the causes, signs, and symptoms of EIPH, horse owners and trainers can take steps to prevent its development and provide optimal care for horses affected by this condition.

Frequently Asked Questions about EIPH in Horses
What is EIPH in horses?
EIPH stands for Exercise-Induced Pulmonary Hemorrhage, which is a condition where horses experience bleeding in their lungs during intense exercise, such as racing or high-intensity training. This can lead to a range of symptoms, including coughing, nasal discharge, and fatigue.
What causes EIPH in horses?
The exact cause of EIPH is still not fully understood, but it is believed to be related to the high pressures and stress placed on the horse’s lungs during intense exercise. Factors such as genetics, training methods, and environmental conditions may also contribute to the development of EIPH.
How is EIPH diagnosed in horses?
EIPH can be diagnosed through a combination of physical examination, endoscopy, and imaging tests such as radiographs (x-rays) or ultrasound. A veterinarian may also perform a bronchoalveolar lavage (BAL) to collect a sample of fluid from the lungs, which can help confirm the presence of bleeding.
How is EIPH treated in horses?
Treatment for EIPH typically involves rest and recovery, as well as management changes to reduce the risk of further bleeding. This may include adjusting the horse’s training program, providing anti-inflammatory medications, and using nasal strips or other devices to help reduce lung pressure. In some cases, surgery may be necessary to repair any underlying anatomical issues.
Can EIPH be prevented in horses?
While EIPH cannot be completely prevented, there are steps that can be taken to reduce the risk of its occurrence. These include providing regular breaks during training, using proper warm-up and cool-down techniques, and ensuring the horse is properly conditioned and fit. Additionally, some studies suggest that the use of certain supplements or medications may help reduce the risk of EIPH.
