Symptoms of intestinal obstruction in dogs and cats?

Intestinal obstruction is a physical or functional obstruction of the intestinal cavity, which prevents the intestinal substances from descending smoothly. It is clinically characterized by severe abdominal pain and obvious systemic symptoms. According to the degree of intestinal obstruction, it can be divided into complete obstruction and incomplete obstruction.

Vomiting, abdominal swelling, abdominal pain, and inability to defecate. Frequent vomiting can lead to obvious symptoms of dehydration in dogs. Due to intestinal obstruction, a large amount of gas accumulates in the intestines, and it is obvious that the dog's abdomen can be swelled. In severe cases, there will be symptoms such as gradual abdominal pain, and the dog's body temperature will also increase and weaken, and sometimes shock will occur.

There are foreign bodies in the intestine, fecal constipation, intestinal parasites, tumors inside and outside the intestine, enteritis, intestinal insufficiency, intestinal strangulation, intestinal torsion, scar formation after intestinal surgery, etc., causing intestinal cavity occlusion to cause mechanical obstruction.

The nerve disorder or inflammation or necrosis that governs the intestinal wall leads to weakening or disappearing intestinal peristalsis, or mesenteric thrombosis, causing disorders in intestinal blood circulation, which in turn paralyzes the muscles of the intestinal wall and retains the contents of the intestinal content.
