What could cause abdominal swelling?

• A. Dehydration
• B. Possible foreign object
• C. Allergic reaction
• D. Constipation

Answer: (B)

Abdominal swelling happens when gas or fluid builds up in the abdomen, often from a blockage in the digestive tract. If a pet swallows a foreign object, it can get stuck in the stomach or intestines, causing an obstruction. That blockage traps gas and fluids behind it, so the abdomen becomes visibly distended and may feel tight or tender. This situation commonly brings signs like restlessness, arching the back, vomiting, and sometimes an inability to pass stool or gas. Because an intestinal obstruction can progress quickly to a serious emergency, it requires prompt veterinary care. Dehydration mainly causes dry mucous membranes and skin, not a swollen belly. An allergic reaction tends to cause swelling in the face or limbs and possible breathing issues, not a distended abdomen. Constipation can cause some abdominal distension, but it’s typically linked to straining and firm stools, while a foreign object is a classic cause of acute, noticeable swelling.
