One of the hardest parts of dealing with colic as a horse owner is knowing when to wait and when to act immediately. Many horses show mild digestive discomfort from time to time, but some colic episodes escalate rapidly and become life-threatening.
Understanding when colic is an emergency can save your horse’s life. This article explains the warning signs that should never be ignored, why certain symptoms are so serious, and how to make calm, informed decisions under pressure.
This guide is written for everyday UK horse owners — not vets — and focuses on clear, practical decision-making.

Why Some Colic Becomes Life-Threatening
Colic becomes an emergency when:
- Pain is severe or uncontrollable
- Blood supply to the gut may be compromised
- The intestine may be twisted, displaced, or blocked
Unlike mild colic, emergency colic does not improve on its own. Delay in treatment can result in irreversible damage, shock, or death.
The Most Important Rule: Severity Matters More Than Duration
A common misconception is that colic must last “a long time” to be serious.
In reality:
- Severe pain for a short time can be more dangerous
- Rapid deterioration is a major red flag
- Intensity of symptoms matters more than the clock
If a horse shows intense pain at any stage, treat it as an emergency. full list of colic symptoms and what they look like
Emergency Sign #1: Violent or Uncontrolled Rolling
Rolling is one of the clearest indicators of serious pain.
Emergency rolling looks like:
- Throwing the body down forcefully
- Repeated attempts to roll
- Inability to stay standing
- Lack of response to distraction
This type of behaviour increases the risk of:
- Injury
- Intestinal twisting
- Shock
👉 Immediate veterinary attention is essential.
Emergency Sign #2: Pain That Does Not Improve
Pain relief that:
- Doesn’t work
- Wears off quickly
- Only provides brief relief
is a major warning sign.
Horses whose pain returns quickly after treatment may have:
- A twist in the intestine
- A severe displacement
- Compromised blood supply
These cases often require urgent referral.
Emergency Sign #3: Excessive Sweating
Sweating without exercise indicates severe stress and pain.
Watch for:
- Patchy or full-body sweating
- Damp or dripping coat
- Sweating combined with restlessness
Sweating is often associated with:
- Severe abdominal pain
- Shock
- Rapid deterioration
Emergency Sign #4: Rapid Heart Rate and Breathing
Increased heart rate is one of the most reliable indicators of severity.
Concerning signs include:
- Heart rate consistently above normal
- Rapid, shallow breathing
- Flared nostrils
These changes indicate the horse is under extreme stress and may be entering shock.
Emergency Sign #5: Abnormal Gum Colour
Checking gums can provide valuable information if you know what to look for.
Warning signs:
- Pale or white gums
- Dark red or purple gums
- Slow capillary refill time
Abnormal gum colour suggests poor circulation, which is a medical emergency.
Emergency Sign #6: Signs of Shock
Shock is a life-threatening condition.
Possible indicators include:
- Weakness
- Cold extremities
- Dull or glazed eyes
- Rapid deterioration
Shock requires immediate veterinary intervention.
Repeated Colic Episodes in a Short Time
Even if individual episodes seem mild, repeated colic within hours or days can indicate a serious underlying issue.
Never ignore recurring pain — it often points to:
- Ongoing obstruction
- Gut displacement
- Management-related problems

Why “Waiting to See” Can Be Dangerous
Owners often hesitate because:
- The horse looks better briefly
- They fear overreacting
- They hope it will pass
Unfortunately, waiting is one of the biggest risk factors in severe colic outcomes.
Calling the vet early is always the safer choice.
What To Do Immediately in an Emergency
If you believe colic is an emergency:
- Call the vet immediately
- Remove all feed
- Keep the horse as safe as possible
- Avoid unnecessary movement
- Follow veterinary instructions closely

Emergency Colic and Referral Decisions
Some cases require referral to an equine hospital.
Factors that influence referral:
- Severity of pain
- Response to treatment
- Heart rate
- Findings on examination
Referral decisions can feel overwhelming, but early referral often improves outcomes.
Emotional Decision-Making and Colic
Colic emergencies are emotionally charged.
Remember:
- Acting early is responsible, not dramatic
- Asking for help is good horse ownership
- Calm decisions save lives
No owner should feel judged for calling the vet.
How Knowing the Early Signs Helps Prevent Emergencies
Many emergencies start as mild cases.
Recognising:
- Subtle behaviour changes
- Appetite changes
- Dropping irregularities
can prevent escalation.
