Horse Gas Colic: Causes, Symptoms, and Treatment


Horse gas colic is a common digestive disorder that affects horses of all ages and breeds. It is caused by an accumulation of gas in the horse’s gastrointestinal tract, which can cause discomfort, pain, and even death if left untreated. Gas colic can occur for a variety of reasons, including changes in diet, stress, and lack of exercise.

Symptoms of horse gas colic can vary depending on the severity of the condition. Mild cases may only cause mild discomfort and restlessness, while more severe cases can cause severe abdominal pain, bloating, and even collapse. Treatment for gas colic typically involves a combination of medication, dietary changes, and exercise to help relieve the symptoms and prevent further complications.

Signs and Symptoms

Horse gas colic is a common condition that can cause discomfort, pain, and even death in horses. It is important to recognize the signs and symptoms of this condition to provide prompt and appropriate treatment.

Physical Indicators

One of the most common physical indicators of gas colic in horses is rolling. Horses with gas colic will often roll on the ground repeatedly, trying to find relief from the pain. They may also paw at the ground, lie down and get up frequently, stretch their flank, and kick at their belly.

Another physical indicator of gas colic is sweating. Horses with this condition may sweat profusely, particularly  around the neck and shoulders. They may also bite at their sides and stretch outs if trying to relieve the pain.

Behavioral Changes

In addition to physical indicators, horses with gas colic may exhibit behavioral changes. They may become depressed, lethargic, and show a lack of interest in food and water. They may also show a decrease in activity and become less responsive to their surroundings.

It is important to note that the signs and symptoms of gas colic can vary from horse to horse. Some horses may show only mild symptoms, while others may exhibit severe signs of pain and distress. If you suspect that your horse may have gas colic, it is important to contact a veterinarian immediately.

Causes of Gas Colic

Dietary Factors

Dietary factors are one of the most common causes of gas colic in horses. Overfeeding or feeding the wrong type of feed, such as too much grain or too little forage, can lead to excessive gas production in the hindgut. Feed changes, particularly sudden changes, can also contribute to the development of gas colic. Horses that are fed low-quality hay or forage may be at a higher risk of developing impactions, which can lead to gas colic.

Environmental Factors

Environmental factors can also play a role in the development of gas colic in horses. Stress, lack of exercise, and confinement can all contribute to the development of gas colic. Horses that are kept in stalls for extended periods of time may be more prone to developing colic due to decreased gut motility and increased gas production.

Biological Factors

Biological factors can also contribute to the development of gas colic in horses. Bacteria, parasites, and other microorganisms in the intestinal tract can produce excessive gas, leading to colic. Inflammation, impactions, twists, and displacements in the large colon and intestines can also cause gas colic. Dehydration and overload of the hindgut with excessive feed can also lead to gas colic.

In order to prevent gas colic in horses, it is important to provide a balanced diet with adequate forage and to make any feed changes gradually. Providing regular exercise and turnout can also help to promote gut motility and prevent the buildup of gas in the intestinal tract. Regular veterinary check-ups and deworming can also help to prevent the development of gas colic.

Diagnosis and Monitoring

Veterinary Examination

When a horse shows signs of gas colic, the first step is to call a veterinarian. The vet will perform a physical exam and assess the horse’s vital signs, including heart rate and respiratory rate. The vet will also perform a rectal exam to check for impactions or other abnormalities in the abdominal cavity.

In some cases, the vet may take a sample of the horse’s manure or feces for analysis. This can help determine if there is an infection or other underlying condition causing the colic.

If the vet suspects that the horse has gas colic, they may recommend additional monitoring. This may include checking the horse’s heart rate and vital signs every few hours, and monitoring the horse for signs of improvement or worsening.

Owner’s Role

As a horse owner, it is important to be aware of the signs of gas colic and to contact a vet immediately if you suspect your horse is experiencing colic. You can help the vet by providing information about your horse’s symptoms and behavior, as well as any recent changes in diet or routine.

During the veterinary exam, it is important to follow the vet’s instructions and to stay calm and quiet around the horse. The vet may ask you to help hold the horse or to provide additional information about the horse’s behavior or medical history.

After the vet has diagnosed gas colic, it is important to follow their instructions for monitoring and treatment. This may include administering medications, adjusting the horse’s diet, or providing additional monitoring and care. By working closely with your vet, you can help ensure the best possible outcome for your horse.

Treatment and Management

Horse gas colic is a serious condition that requires prompt treatment and management. The following interventions can be used:

Medical Interventions

Medical interventions are the first line of treatment for horse gas colic. The following medications can be used:

  • Pain relief medications such as flunixin meglumine and butorphanol tartrate can be administered to relieve pain.
  • Stomach tubes can be used to relieve gas and fluid buildup in the stomach.
  • Mineral oil can be administered to lubricate the intestines and help pass any blockages.
  • Antibiotics can be used to treat any bacterial infections that may have caused the colic.

Surgical Interventions

Surgical interventions are necessary in severe cases of horse gas colic. The following surgeries can be performed:

  • Laparotomy: This surgery involves making an incision in the horse’s abdomen to remove any blockages or twists in the intestines.
  • Colic surgery: This surgery involves removing a portion of the intestine that has been damaged beyond repair.

Home Care

After medical or surgical interventions, the horse requires proper care and support to recover. The following steps can be taken:

  • The horse should be walked to help prevent complications such as laminitis and encourage bowel movement.
  • The horse should be provided with a clean and comfortable environment.
  • The horse should be given plenty of fluids to prevent dehydration.
  • The horse’s diet should be monitored and adjusted as needed.
  • Parasite control and regular health care should be maintained to prevent future episodes of colic.

Prevention of Gas Colic

Gas colic is a preventable condition, and there are several steps that horse owners can take to minimize the risk of their horses developing it. Here are some key prevention measures to keep in mind:

Feeding Practices

One of the most important factors in preventing gas colic is maintaining a consistent feeding routine. Horses should be fed at the same time each day, and their diet should be consistent. Sudden changes in feed or feeding schedule can lead to digestive upset.

It’s also important to ensure that horses have access to plenty of clean water at all times. This will help keep their digestive system functioning properly and prevent dehydration, which can exacerbate colic symptoms.

Exercise and Stress Management

Regular exercise is crucial for maintaining a healthy digestive system and reducing the risk of colic. Horses should have access to turnout or exercise on a daily basis, and their workload should be gradually increased over time.

Stress can also contribute to colic, so it’s important to minimize sources of stress in horses’ environments. This can include reducing exposure to loud noises or sudden movements, as well as providing horses with plenty of social interaction and mental stimulation.

Regular Veterinary Care

Regular veterinary care is essential for preventing and managing colic. Horses should receive regular check-ups and dental exams, and their deworming schedule should be carefully managed to prevent parasite infestations.

In addition, horse owners should be familiar with the signs of colic and know when to seek veterinary attention. Early intervention is key to successful treatment and a positive prognosis.

By following these prevention measures, horse owners can minimize the risk of gas colic and promote overall horse health.
