Horse Colic Symptoms: A Concise Guide to Early Detection

Horse colic is a term used to describe a variety of conditions that cause abdominal pain in horses. Colic has a wide range of causes and severity levels, making it essential for horse owners and caretakers to recognize the symptoms and seek appropriate treatment when necessary. An understanding of a horse’s digestive system and the causes of colic is crucial in identifying the symptoms and taking timely action to help the animal.

Some common signs of colic in horses include biting or kicking at their flank or belly, frequently looking at their side, and lying down or rolling more than usual. Additional symptoms may include disruptions in passing manure, such as passing little or no manure, smaller fecal balls, or dry or mucus-covered manure. These signs may vary depending on the horse’s personality and the underlying cause of the colic. By closely monitoring a horse’s behavior and physical health, owners can identify potential colic symptoms and take appropriate steps to address the issue and ensure their horse’s well-being.

Identifying Horse Colic Symptoms

Typical Signs

When identifying horse colic symptoms, it’s essential to know the typical signs that a horse might display. Some of the most common signs include restlessness, pawing at the ground, and rolling. Horses suffering from colic may also kick at their belly, indicating abdominal pain. Another sign to watch for is if the horse is consistently lying down and getting up multiple times, as this can signal discomfort.

Colic-affected horses may also have increased heart rates, usually over 50 beats per minute. Monitoring the horse’s pulse is crucial in detecting early colic signs, as an elevated pulse can indicate a painful condition. It’s also essential to observe any changes in behavior, including dullness or lethargy, which can be symptoms of colic.

Abnormal Behaviors

Aside from the common signs mentioned above, there are other abnormal behaviors to look for that could indicate colic in horses. One such behavior is playing in their water bucket without actually drinking. This unusual activity can be a sign of discomfort or pain related to colic.

Another noteworthy symptom is the absence of defecation. If the horse is not passing feces, it may signify an issue with their digestive system, such as an impaction or twist in the intestines, indicating colic. Additionally, a lack of appetite can be a sign, as horses experiencing colic may not feel well enough to eat.

Lastly, excessive sweating can signal colic in horses, especially when accompanied by other symptoms like restlessness or increased heart rate. This excessive perspiration could be a response to the painful abdominal condition.

Understanding Different Types of Horse Colic

Impaction Colic

Impaction colic occurs when there is a blockage in the horse’s intestinal tract, often caused by a buildup of ingested material that becomes dry and difficult to pass. This type of colic is relatively common and is often associated with dehydration, changes in diet, or decreased physical activity. An impacted large intestine can result in severe pain for the horse, and treatment usually involves administration of fluids and medications to soften and pass the impaction.

Gas Colic

Gas colic is characterized by an excessive buildup of gas within the horse’s large intestine. Gas can accumulate in the intestines when a horse consumes large amounts of feed, or when it is experiencing stress or other gastrointestinal issues. This type of colic typically causes the horse to look bloated and experience abdominal pain. Treatment for gas colic involves medication to help relieve the buildup of gas and alleviate discomfort.

Spasmodic Colic

Spasmodic colic, also known as intestinal cramping, is one of the most common types of colic in horses. It is often the result of intestinal spasms, which can be induced by sudden changes in diet, stress, or enteritis. Horses with spasmodic colic may display signs of pain, such as pawing at the ground, rolling, or turning to look at their sides. Medical intervention with antispasmodic medications can help alleviate the pain and discomfort experienced in this type of colic.

Sand Colic

Sand colic occurs when horses consume large amounts of sand or soil while grazing, often accidentally. This ingested material accumulates in the large intestine, which can lead to impaction and irritation of the intestinal lining. Factors such as environmental conditions and management practices can contribute to a higher risk of sand colic. To prevent sand colic, it is essential to provide a clean and safe grazing environment and monitor horses for signs of sand ingestion, such as changes in manure consistency.

Displacement and Torsion Colic

Displacement colic occurs when a portion of the horse’s intestine moves from its normal position within the abdominal cavity, causing stretching, irritation, and pain. Torsion colic, also known as twisted gut, is a more severe condition, where the intestine has twisted upon itself, effectively cutting off the blood supply. Both displacement and torsion colic can be life-threatening and often require emergency surgery to correct the issue.

Causes of Horse Colic

Feed-Related Causes

One of the primary causes of colic in horses is related to their feed. Sudden changes in diet, such as transitioning from hay to grain or vice versa, can disrupt the balance of microorganisms in the gastrointestinal tract, leading to colic. Moreover, feeding poor-quality hay can increase the risk of impaction due to its low digestibility.

In sandy areas, sand accumulation in the gut may also cause sand colic, which results from the ingestion of sand during grazing. To prevent this issue, owners should ensure proper feeding management by offering raised hay/feed nets and providing mineral oil to help sand pass through the digestive system.

Environmental Causes

Environmental factors, such as stress, temperature changes, and inadequate water intake, can also contribute to the onset of colic. Cold weather during winter can cause horses to drink less water, leading to dehydration and an increased risk of impaction colic. It is crucial to maintain a consistent supply of fresh water at a suitable temperature, so the horse remains hydrated throughout the year.

Stressful situations, such as transportation or changes in routine, can also lead to colic in horses. Maintaining consistency in your horse’s environment and routine can help minimize stress-related colic incidents.

Health-Related Causes

Various health issues can increase the risk of colic in horses, including parasites, infections, and underlying diseases. A comprehensive worming program is essential to maintain your horse’s ongoing gastrointestinal health and prevent colic caused by internal parasites. Regular fecal testing and administration of appropriate deworming medication help keep internal parasites in check.

Certain infections and diseases, such as gastric ulcers and enteritis, can also contribute to colic episodes. To minimize these risks, proper ongoing health management, including regular veterinary exams and monitoring your horse’s behavior for any signs of discomfort or distress, is essential.

Initial Responses to Colic Symptoms


When you suspect colic symptoms in your horse, the first step is to carefully observe the animal’s behavior and physical condition. Common signs of colic include restlessness, biting at the abdomen, sweating, and frequent changes in position. You should monitor your horse’s temperature and pulse to identify any abnormalities. It is important to pay close attention to the horse’s abdominal area, as the pain can intensify and manifest in different ways, such as rolling, excessive stretching, or lying down and getting up frequently.

In order to accurately assess the situation, you should also observe the horse’s environment and recent changes, such as alterations in diet or exercise routines, which may contribute to colic symptoms.

Making the Call to the Veterinarian

Once you have identified potential colic symptoms, it is crucial to contact a veterinarian immediately. Early detection is vital, as a timely response can increase the chances of a successful recovery for the horse. A confident and knowledgeable veterinarian will guide you on how to manage the situation until a professional examination can be conducted. This may involve instructions to withhold feed, administer first-aid treatment, or conduct ongoing monitoring of the horse’s condition.

The veterinarian will assess the severity of the colic and decide whether the horse requires medical intervention, surgery, or if the situation can be resolved through conservative management. By working together with a skilled veterinarian, you can ensure that you provide the best possible care for your animals during a colic episode.

Diagnosis of Horse Colic

Physical Examination

A thorough physical examination is the first step in diagnosing horse colic. The veterinarian will evaluate the horse’s overall condition by assessing the heart rate, respiratory rate, temperature, and any abnormal behaviors. A history of the horse’s health, management, and recent activities will also be collected. An increased heart rate and signs of abdominal pain may suggest colic. It’s important to note any changes in manure production, as this may be a clue to the underlying cause.

Rectal Examination

Rectal palpation is a crucial diagnostic tool for horse colic. The veterinarian gently inserts a gloved hand into the rectum to assess the position and contents of the abdominal cavity. This helps identify any abnormalities, such as impactions, displacements, or masses. It’s important to be gentle during a rectal examination, as there is a risk of causing injury to the horse.

Ultrasound and Other Diagnostic Tools

Additional diagnostic tools may be required to provide a definitive diagnosis for horse colic. These may include a nasogastric tube, which is inserted through the nostril and into the stomach to check for reflux and gastric content. Reflux may indicate an obstruction or impaction causing the horse’s discomfort.

Ultrasound is a valuable tool for diagnosing colic, as it allows the veterinarian to visualize structures in the abdominal cavity. This can be especially helpful in identifying fluid accumulation or changes in the intestines. Radiography may also play a role in diagnosis, particularly if there is a concern for a foreign body or when examining foals with suspected colic.

Abdominocentesis, or the collection of fluid from the abdominal cavity, can also be useful in the diagnosis of colic. Analyzing this fluid can provide information about inflammation, infection, or injury that could contribute to the horse’s discomfort.

Treatment and Management of Horse Colic

When dealing with colic in horses, it’s essential to proceed with appropriate treatment and management strategies. Timely intervention can make a significant difference in the horse’s recovery and overall health.

Medical Management

In most cases, mild colic can be medically managed with the help of a veterinarian. For spasmodic colic and gas colic, the veterinarian may administer medication like bute or banamine to alleviate abdominal pain and relax the intestinal muscles. The horse may also need a nasogastric tube to remove excess gas or fluids from the stomach.

Encouraging the horse to walk gently, exercise, or roll can help release trapped gas and relieve discomfort. However, it’s crucial to monitor the horse closely during these activities to avoid further complications. If lying down, make sure the horse rests on a padded surface to prevent injuries.

Managing the horse’s feed and water intake is also essential. Provide clean, fresh water, and monitor the horse’s consumption. Gradually reintroduce feed after the colic episode, starting with hay before slowly reintroducing grain. Implementing a regular deworming schedule and monitoring for diseases can also help prevent future colic episodes.

Surgical Intervention

In some cases, medical management might not be sufficient to treat colic, especially in cases involving impaction, torsion, or strangulation. When this occurs, surgical intervention may be necessary.

The veterinarian will determine if surgery is the best course of action based on the horse’s symptoms, the severity of the colic, and the response to medical treatment. During surgery, the veterinarian may remove any obstructions, untwist the intestines, or repair damage to the digestive tract.

Post-surgical care is crucial for a horse’s recovery. Monitor the horse for complications, administer prescribed medications, and maintain a clean and comfortable environment. The veterinarian may also recommend a specialized diet and exercise regimen, as well as regular check-ups, to ensure a smooth recovery process.
