A distended belly can also be gas. If not allowed to pass, it may develop into bloat which is a painful condition.

There is no medication I know of that would help him quickly eliminate the sludge in his bladder.
dongzheng410's request for ill hamster advice [edit: guinea pig]
Yes, I've been applying heat packs to his abdomen for the past two days, and he seems to be feeling better now. My greatest concern is the sludge in his bladder. After his IV drip that day, he passed a significant amount of sludge. Does this indicate the sludge might be expelled naturally? Is this a positive sign? Additionally, she defecated eight times the day before yesterday and today passed over 150 well-formed stools. Are these also positive signs? She continues to urinate, but refuses to move afterwards, resulting in persistent dampness around her abdomen. I've also noticed clear nasal discharge. Twice today I heard snoring-like breathing sounds. Recent examinations persistently reveal epithelial cells, leading me to suspect that maintaining the indoor temperature around 24°C with the air conditioning on may have caused her to catch a chill, potentially leading to a pulmonary infection. Her systemic inflammation appears persistent—the previous bladder infection was only temporarily alleviated by antibiotics without resolving the underlying issue. Thus, despite outward normality, closer observation reveals recent symptoms including lethargy, listlessness, and teeth grinding. Local vets routinely employ canine/feline treatment protocols, prescribing only amoxicillin or sulphonamide antibiotics, which I believe are unsuitable for her. Can pigs catch colds?
