7 Common Signs of Impaction in Tortoises

(Last Updated On: January 31, 2023)

Fecal impaction is often used interchangeably with bowel obstruction (intestinal obstruction).

A bowel obstruction refers to a blockage caused by foreign objects (pebbles, substrate, hair, etc.), while fecal impaction only refers to a blockage caused by hardened feces (poop).

Impaction is regularly confused with constipation. While the latter condition is uncomfortable, it’s not as serious. Fecal impaction is a life-threatening condition that needs immediate medical attention.

If you think that your tortoise is impacted, take them to a vet for an X-ray.

Tortoise Straining To Poop

If your tortoise is straining to poop, it likely has constipation or impaction.

Constipation is when the stool becomes hard and lumpy, so a tortoise will find it hard to pass. Impaction happens when the stool becomes stuck in the bowels.

If you notice your tortoise straining to poop, let your tortoise soak for 20-30 minutes and offer it a natural laxative, such as mashed banana and pumpkin.

If your tortoise is truly impacted, home remedies won’t be sufficient.

There are two common ways that the bowels can be blocked:

Bowel Obstruction

Bowel obstruction, also known as intestinal obstruction, is often caused by ingesting foreign objects, such as cat litter, grass, or hair.

Ingesting substrate is a common cause of blockage in tortoises. For example, the Journal of Small Animal Practice discusses how a testudo ingested pebbles, causing bowel obstruction.

Also, bladder stones and egg binding can cause a blockage, leading to bowel obstruction.

Fecal Impaction

Fecal impaction is similar to a bowel obstruction but is caused by hardened feces. Because both are functionally similar, fecal impaction and bowel obstruction are used interchangeably.

The most common reason for fecal impaction is dehydration. Because the stool doesn’t have enough moisture, it can become hard and lumpy and cannot be passed.

Tortoise Impaction Symptoms

Impacted tortoises will share the symptoms of constipated tortoises. However, they’ll have some additional signs that are unique to the condition.

Here are the most common indicators of impaction in tortoises:

1/ Straining

Tortoises that strain have trouble with their bowel movements, and they may even vocalize with grunts as they try unsuccessfully to pass their stool.

If your tortoise has been impacted for a long time, it may not strain. Impaction can weaken a tortoise, leaving it with little energy to strain.

If your tortoise stops straining, it doesn’t mean that constipation or impaction has resolved.

If your tortoise has no other symptoms, it may be constipated.

2/ Prolapse

When a tortoise strains too much, it can cause prolapse. Prolapse occurs when an internal organ can be seen outside the tortoise’s body, specifically its vent.

Not all types of prolapse are a cause for concern. Males, during intercourse, will have a prolapsed sexual organ, but this organ should return to the body within a few minutes.

Aside from this instance example, prolapse is a medical emergency. Prolapsed internal tissue will look like red material from the vent in a fold or bubble shape.

This internal tissue will become swollen and damaged. The longer it remains outside the body, the more it becomes necrotic.

A vet will determine the cause of the straining. If it’s fecal impaction, the impaction will need to be removed to prevent prolapse from happening again.

Any rotten tissue will be surgically removed, and the organs will be placed back inside the body.

3/ Vomiting

Impaction can cause vomiting when the food has nowhere else to go.

A buildup of food inside the gut may cause it. For example, the Journal of Herpetological Medicine and Surgery describes how a Red-footed Tortoise was vomiting due to an intestinal blockage.

4/ Lack of Poop

If you notice that your tortoise hasn’t pooped for more than 3 days, it could be impacted.

However, a lack of poop isn’t the most reliable symptom of impaction, especially if it’s the only symptom your tortoise is experiencing. For example, a lack of poop can mean a tortoise isn’t eating.

Give your tortoise a 20-minute soak in a shallow bowl of warm water.

5/ Lethargy And Weakness

If your tortoise doesn’t poop and seems weak, it’s likely to be impacted. After all, impaction strains a tortoise’s internal organs, making it sluggish.

If a tortoise is lethargic, it’ll display the following behaviors:

6/ Breathing Difficulties

Fecal impaction makes breathing hard as pressure is exerted on the internal organs.

Breathing problems in tortoises will manifest in the following ways:

  • Extended neck
  • Moving the head strangely to get better airflow
  • Neck placed outside of shell for longer or more often than usual

7/ Lack of Appetite

A constipated tortoise is likely to reduce the amount of food it consumes.

It may feel bloated and won’t want to eat as much as it usually does. Impacted tortoises may stop eating altogether. Aside from feeling bloated, it may simply feel too tired to eat.

Note that a lack of appetite is a common symptom of many illnesses. For example, your tortoise may have an infection, feel uncomfortable in its enclosure, and dislike the food you’re offering.

Fecal Impaction vs. Constipation

Here’s how to tell fecal impaction and constipation apart:

ConstipationFecal Impaction
Definition:Difficulty in passing stools.A blockage of the bowels.
Symptoms:Hard and lumpy stool, painful bloating, and stomach crampsSymptoms of constipation, pain or swelling in the lower back or lower abdomen, breathing difficulty, weakness, and lack of appetite.
Causes:Fecal impaction or bowel obstruction, stress, illness, intestinal parasites, poor nutrition, and damage to the gastrointestinal muscles.Ingestion of foreign objects, improper nutrition, egg binding, and bladder stones.

How Long Can A Tortoise Go Without Pooping?

Tortoises poop less often than most pets, passing waste once every 2-3 days. Some tortoises will poop more often than others.

How often a tortoise goes to the toilet depends on its diet, especially how much water is in it.

How To Prevent Impaction In Tortoises

Impaction is a serious condition, but there are ways to avoid it:


Avoid giving your tortoise any dried food.

Even if it’s soaked in water afterward, dried food contains little moisture compared to fresh food.

The best diet for tortoises resembles the meals they would eat in the wild. Provide your tortoise with a diet rich in fiber and calcium but with low levels of protein and fat.


When tortoises are dehydrated, they’re at a greater risk of developing hard stools.

To prevent impaction, ensure that your tortoise has access to water, and its diet is high in moisture. Also, make sure that your tortoise’s habitat has sufficient humidity.

Small Stones

If you want to add stones to your tortoise’s enclosure, ensure they’re too large to fit in your tortoise’s mouth. Remove any mouth-sized rocks or pebbles.


Ensure that your tortoise has bedding that can be easily passed if consumed.

Substrates to avoid include the following:

  • Walnut shells
  • Corn cob
  • Cat litter
  • Sand

Avoid anything that is undigestible and can block the gastrointestinal tract.

Tortoise Impaction Treatment

A vet should see impacted tortoises promptly, as impaction can be fatal if left untreated. A vet can use x-rays to determine the cause of the impaction, offering surgery to remove the blockage.

In the interim, you can make your tortoise more comfortable. This can be achieved by soaking it in warm water, giving it a natural laxative, and keeping its enclosure warm and humid.
