Excessive signs of weight loss in rabbits could indicate infection from which disease?

Excessive signs of weight loss in rabbits can often indicate coccidiosis, which is a parasitic infection that affects the intestinal tract of rabbits. This disease is caused by protozoan parasites from the genus Eimeria, which can lead to significant weight loss due to malabsorption of nutrients and severe diarrhea. When the parasites invade the intestines, they damage the lining, impeding the rabbit's ability to absorb food properly, which contributes to weight loss and overall poor health.

In contrast, other conditions have different manifestations or causes. Myxomatosis is a viral disease that typically presents with swelling around the eyes and excessive discharge, rather than direct weight loss alone. Dental disease can also lead to weight loss, but it is more often accompanied by signs of oral pain or difficulty eating, as the rabbit struggles to consume food. VHD (Viral Hemorrhagic Disease) can lead to sudden death or very rapid decline in health without prolonged weight loss being the primary sign at the onset.

Understanding the specific impacts of coccidiosis on a rabbit's health reveals why it is crucial for owners to monitor for signs of this condition and recognize excessive weight loss as a serious indicator that requires veterinary attention.
