Many metabolic diseases in guinea pigs are caused by nutritional deficiencies. Here it is necessary to especially note vitamin C hypovitaminosis, the clinical symptoms of which are paralysis, joint seals, bleeding in the muscles, unwillingness to move and death. 

As a treatment and preventive measures, it is recommended to give animals a food rich in vitamin C: sprouted cereals, fresh grass and green food, as well as ascorbic acid mixed with water (100 mg / 100 ml of water). Another nutritional disease is Soft Tissue Calcification, which can be caused by an imbalance of phosphorus and calcium (1: 2), as well as vitamin D hypervitaminosis. This disease, which affects most males, is most often possible only during autopsies. Clinically, the disease rarely manifests itself. Feeding the animals with enough hay should prevent organ recognition, in which lime deposits are found in the stomach, intestines and liver. 

Other nutrition-related metabolic diseases are also described in the literature. During the history, the veterinarian should ask in detail about the diet to which the animals are accustomed to indicate the change in the composition of the feed necessary for prevention. Improper nutrition often sets the stage for infectious and parasitic diseases. 

Leukemia 

In guinea pigs, virus-induced leukemia caused by oncoviruses is known. The leukocyte count rises to 250,000 per cubic millimeter. The lymph nodes swell. No cure is known, no chance of recovery.
