Why is my guinea pig skinny? Is it digestion or other health issues?

Pet's info: Small Animal | Guinea Pig | Male | unneutered

I have a guinea pig and he is getting skinny day by day, I took him too the vet but he says that milo(my guinea pig) is having some digestion problem and I should give him some liver tonic but I searched the whole internet and couldn't find anything regarding this, so I'm worried whether he is really having some digestion problem or something else.

Thanks for reaching out about Milo. There are many possible causes of weight loss in guinea pigs including dental disease, metabolic disorders (liver, renal), urinary disease (urinary tract infections, bladder stones), nutritional deficiencies (vitamin C is common) and others. Many of these can also cause gastrointestinal upset, therefore treating the GI disorder is not the primary problem. It is recommended you seek a veterinary visit with one with experience in small exotic companion mammals. You can try the website for the Association of Exotic Mammal Veterinarians (AEMV.org). Try offering softer food for now. Good luck.
