Colon Enlargement in cats
Colon enlargement in cats, also known as megacolon, is an abnormal enlargement of the large intestine that leads to severe constipation and difficulty defecating.
Can Occur with the Following Diseases:
Basics and possible causes
Colon enlargement is a condition in which the large intestine, also called the colon, loses its ability to transport stool normally. This can be triggered by a variety of causes, which can be both functional and structural in nature. The main function of the colon is to absorb water from the stool and pass the undigested residue out of the body. In colon enlargement, this function is impaired, leading to an accumulation of highly compacted stool.
The most common causes include idiopathic factors, meaning that the origin is unknown. Sometimes there may be a neuromuscular dysfunction of the intestine, in which the nerves and muscles of the colon do not work properly. Mechanical obstructions, such as tumors or strictures, can also impede normal stool transport. Another possibility is secondary enlargement, which results from chronic constipation, in which the colon becomes overstretched and loses its normal peristalsis.
In addition to these causes, neurological disorders affecting the intestine can also lead to colon enlargement. Injuries to the spinal cord or neurological diseases that affect the nerve supply to the colon could also play a role. Finally, certain medications or systemic diseases, such as hypothyroidism, can also lead to intestinal motility disorders, resulting in colon enlargement.
Typical accompanying symptoms
-
Chronic constipation: The cat has difficulty defecating, and the stool is often hard and dry, indicating a prolonged stay in the colon.
-
Lethargy: The cat often appears tired and disinterested in its surroundings, which may be due to the strain of the accumulated stool.
-
Loss of appetite: Due to discomfort or abdominal pain, the cat may eat less or not at all.
-
Vomiting: A cat with colon enlargement may occasionally experience vomiting, especially if the gastrointestinal tract is severely affected.
-
Weight loss: In the long term, food intake may be impaired, leading to a steady weight loss.
-
Abdominal pain: The cat may show signs of pain when the abdomen is touched, which is due to the distension of the intestine.
When to visit the vet?
A veterinarian should be consulted immediately if the cat has not passed stool for more than two days or if it shows signs of discomfort, such as vomiting, loss of appetite, or lethargy. These symptoms may indicate a serious disorder that requires immediate medical intervention.
Also, if blood is visible in the stool or vomit, or if the cat shows severe pain, a quick visit to the veterinarian is necessary. This could indicate a complication that requires immediate treatment to prevent permanent damage.
In addition, it is advisable to consult the veterinarian for recurring episodes of constipation or other intestinal problems in order to clarify the underlying cause and initiate appropriate therapy.
Symptom recognition for animal owners and veterinary diagnostic procedures
The symptoms of colon enlargement can be difficult for the pet owner to recognize, as cats are often discreet when it comes to pain or discomfort. Close observation of stool behavior is therefore crucial. If the cat passes stool less often than usual or shows straining without success, this is a clear indication of a problem.
The veterinarian will first perform a thorough clinical examination to assess the cat’s general health. Palpation of the abdomen can provide information about whether the colon is enlarged or whether hard stool residues are palpable. In some cases, the veterinarian may order an X-ray to better assess the size and shape of the colon.
Additional diagnostic tests may include blood tests to rule out other systemic diseases that could lead to colon enlargement. Ultrasound examinations can also be helpful in identifying structural abnormalities or obstructions in the intestinal tract.
What can pet owners do and professional therapy options
As a first step to relieve symptoms, the pet owner can try feeding the cat a high-fiber diet to promote intestinal motility. It is important to ensure that the cat drinks enough to soften the stool and facilitate passage.
In some cases, the pet owner can try to encourage the cat to get more exercise, as physical activity can stimulate intestinal activity. However, this should be done carefully and without coercion to avoid additional stress.
If the constipation is severe or the symptoms cannot be relieved quickly, the pet owner should not hesitate to seek the support of a veterinarian. The veterinarian can then prescribe appropriate medications to soften the stool or stimulate bowel movements, and in extreme cases, an enema may be necessary to relieve the bowel.
