Ulcers are a common issue for horses, with over 60% of horses suffering from gastric ulcers. These are often caused by the high levels of acid in the horse's stomach, combined with stress and gut disturbances. Horses with gastric ulcers may experience chronic muscle tension, particularly in the Psoas muscle group, which is one of the largest and strongest muscle groups in the horse's body. This tension can lead to restricted movement, reduced performance, and an increased risk of injury. The link between ulcers and muscle tension in horses is a complex issue, with physical imbalances and stress potentially contributing to a cycle of ulcers and physical compensations.

Ulcers can cause chronic tension in the Psoas muscle group, which is one of the largest and strongest muscle groups in a horse's body
Ulcers are a common issue for horses, with over 60% of horses suffering from gastric ulcers. They are described as painful lesions in the stomach lining, often caused by the high levels of acid in the horse's stomach. This acid can burn holes in the stomach lining, the small intestine, or the large bowel. When these burns heal, they can create scar tissue, which can lead to colic. Horses with gastric ulcers may experience pain and restricted movement, impacting their performance and making them more prone to injury.
One muscle group that is often affected by ulcers is the Psoas muscle group, which is one of the largest and strongest muscle groups in a horse's body. The Psoas muscle group is responsible for stabilising and protecting the pelvic girdle. It helps to prevent fractures of the pelvis, for example, when a racehorse bolts from the starting gate. When the Psoas muscle is in pain, the pelvis and croup muscles cannot function properly, leading to spasms and pain.
The presence of ulcers can cause chronic tension in the Psoas muscle group. This tension can be a result of the horse's posture and movement in response to the pain and discomfort caused by the ulcers. Horses with stomach problems may adopt a compensatory posture, keeping their backs stiff and moving with tension. They may also show signs of tightness, listlessness, bucking, or refusal to work. The pain caused by stomach ulcers can be transmitted through the nerves at the withers to the brain, leading to increased muscle tension and sensitivity in the withers area.
Additionally, the physical pain and discomfort associated with ulcers can contribute to a cycle of increased tension in the Psoas muscle group. The pain can lead to a reduction in appetite and weight loss, further weakening the horse's overall condition. This can result in a loss of muscle mass, including in the Psoas muscle group. The cycle of pain, discomfort, and weight loss can perpetuate the chronic tension in the Psoas muscle, impacting the horse's performance and well-being.
Treating ulcers and managing pain and tension in the Psoas muscle group is crucial for the horse's health and performance. This may include veterinary care, medication to relax muscles and reduce pain, and chiropractic therapy to loosen joints and relieve muscle tension. It is important to work with a veterinarian to determine the root cause of the ulcers and tension and to implement appropriate treatments and management strategies.

Ulcers can cause a horse to adopt a compensatory posture, such as keeping its back stiff, which can lead to muscle tension
Ulcers are a common issue for horses, with over 60% of horses suffering from gastric ulcers. These are painful lesions in the stomach lining caused by the high levels of acid in the horse's stomach, in combination with stress and other gut disturbances. Horses are designed to eat small meals frequently, so the modern practice of feeding horses large meals of hay or grain can contribute to the development of ulcers.
The Psoas muscle group, which is frequently impacted by ulcers, is one of the largest and strongest muscle groups in the horse's body. It stabilizes and protects the pelvic girdle. When the Psoas is in pain, the croup muscles cannot function properly and go into spasm, causing further pain. This can lead to a significant loss of performance ability.
The diaphragm is also prone to spasms and dysfunction in horses with ulcers, which can cause a wide range of issues. Horses with ulcers may also experience pain in the back, right hind, and flank as they attempt to brace against the discomfort. This can result in a stiff back and further muscle tension.
It is important to note that the relationship between ulcers and muscle tension can be complex, with physical imbalances potentially making horses more susceptible to ulcers, and ulcers creating physical compensations that inhibit healing.

Ulcers can cause physical imbalances in a horse's body, leading to impaired performance and muscle tension
Ulcers are a common issue for horses, with over 60% of horses suffering from gastric ulcers. These are caused by the high levels of acid in the horse's stomach, in combination with stress and other gut disturbances. As a result, horses with ulcers can experience a range of physical imbalances and impaired performance.
One of the most common signs of ulcers in horses is a reluctance to finish meals or being a "picky eater". This is likely due to the abdominal discomfort caused by the ulcer. Horses with ulcers may also lose weight, develop a coarse coat, and exhibit signs of chronic discomfort, such as listlessness, introversion, or mild depression. They may also show physical signs of muscle tension, such as a stiff back or tightness in the right hind.
The Psoas muscle, which is a group of three muscles that stabilise and protect the pelvic girdle, is often affected in horses with ulcers. Pain in this muscle can lead to spasms in the croup muscles, causing significant loss of performance ability. Horses with ulcers may also experience increased muscle tension in their backs as a result of the pain caused by stomach problems. This can make them more sensitive in the area of the withers and lead to a reluctance to move or run.
In addition, ulcers can cause physical imbalances in the horse's body, such as misalignments in the spine or soft tissues. These imbalances can compromise the nerves that supply proper function to other systems, including organs. As a result, horses with ulcers may develop a compensatory posture, moving with tension and showing signs of bucking or refusal to work. They may also be reluctant to jump in good form, run downhill, or perform specific movements.
It is important to note that the relationship between ulcers and physical imbalances may be a "'chicken and egg' scenario. The physical imbalances may make it more likely for ulcers to develop, or the ulcers may develop due to stress, travel, or training, creating physical compensations in the horse's body to avoid discomfort. Proper diagnosis and treatment of ulcers in horses, in combination with therapies such as chiropractic care or acupuncture, can help to alleviate muscle tension and improve the horse's overall performance.

Ulcers can cause a horse to become reluctant to finish meals, leading to weight loss and muscle atrophy
Horses are biologically designed to graze and forage for food. However, domesticated horses are often fed two large meals a day, which can cause problems. Their stomachs continuously produce acid, even when there is no feed in the stomach. When there is no feed to neutralise the acid, it attacks the stomach lining, causing sores known as ulcers. This can be prevented by ensuring horses have constant access to forage, or by feeding them multiple smaller meals throughout the day.
Ulcers are common in horses, with a prevalence of between 50 and 90%. They can affect any horse but are most frequent in horses that perform athletic activities. Horses with ulcers may show signs of abdominal discomfort, such as reluctance to finish meals or being "picky eaters". This can lead to weight loss and a poor body condition, which may be further exacerbated by decreased absorption of nutrients.
In addition to abdominal pain, ulcers can cause muscle pain and restricted movement. One muscle that is frequently affected is the Psoas, which is one of the largest and strongest muscles in the body. Its function is to stabilise and protect the pelvic girdle. When the Psoas is in pain, the pelvis and croup muscles cannot function properly, leading to spasms and further pain. This can result in a significant loss of performance ability.
To prevent and treat ulcers, it is important to reduce stress and feed horses appropriately. Small, frequent meals or free-choice forage can support the horse's natural digestive function and reduce the risk of ulcers. Medication such as omeprazole can also be used to treat existing ulcers. In addition, working with an equine chiropractor or veterinarian can help to loosen joints, relax muscles, and relieve back pain.

Ulcers can cause gastrointestinal discomfort, resulting in increased stress levels and subsequent muscle tension
Ulcers are a common issue for horses, with an estimated 60-90% of performance horses developing Equine Gastric Ulcer Syndrome (EGUS) at some point. Ulcers are described as painful lesions in the stomach lining, caused by the vast amount of acid the horse's stomach produces, along with stress and other gut disturbances.
The pain caused by ulcers can lead to increased muscle tension in horses. For example, the Psoas muscle, which is one of the largest and strongest muscles in the horse's body, is frequently dysfunctional in ulcer cases. This muscle group stabilises and protects the pelvic girdle. When the Psoas is in pain, the croup muscles can go into spasm, causing further pain and discomfort. Horses with ulcers may also experience diaphragm spasms, which can cause a wide range of issues.
The sympathetic innervation of the stomach is located at the vertebrae at the withers, so when a horse experiences stomach pain, the pain is transmitted through the nerves at the withers to the brain. This leads to increased activity in the autonomic nervous system, resulting in increased muscle tension, particularly in the area of the withers. Horses may also adopt a compensatory posture in response to stomach pain, keeping their backs stiff and moving with tension.
Additionally, the stress associated with ulcers can further contribute to muscle tension. Stress is both a cause and a consequence of ulcer pain. Horses may exhibit stress-related behaviours such as yawning, cribbing, or a change in demeanour, becoming more introverted or withdrawn. This increased stress can lead to a cycle of chronic ulcers and physical compensations, impacting the horse's overall performance and well-being.

Frequently asked questions
Some common signs that your horse may be suffering from stomach ulcers include:
- Loss of appetite
- Weight loss
- A coarse coat
- Frequent yawning
- Listlessness
- Mild depression
- Reluctance to move downhill
- Tightness in the back or right hind
- Sensitivity in the flank
- Bucking
Ulcers cause chronic muscle tension in horses due to the transmission of pain through the nerves at the withers to the brain. The resulting increased activity in the autonomic nervous system leads to increased muscle tension, making the horse more sensitive in the area of the withers. In addition, due to stomach pain, the horse adopts a relieving posture in which it tenses its back.
To relieve muscle tension in horses with stomach ulcers, it is recommended that the training program be reversed. In acute phases, the horse should not be ridden at all. When reintroducing riding, it is important that the horse runs forward and downhill and is satisfied under the saddle. Medications may also be prescribed to help relax the muscles and soft tissue, as well as reduce pain and inflammation.
