Respiratory distress in snakes can manifest similarly to symptoms in other animals.

Symptom	Possible Cause	Location	Concern Level	Action Needed
Foul Smells	Infected wounds	Body	High	Consult vet
Cloacal Discharge	Infection/Inflammation	Cloaca	High	Seek treatment
Oral Discharge	Mouth rot	Mouth	Severe	Veterinary care
Nasal Discharge	Respiratory disease	Nose	Urgent	Medical evaluation
Bleeding or Pus	Bacterial infection	Wounds or mouth	Critical	Immediate action

Changes in Eye or Mouth Condition

Pay close attention to your snake’s eyes and mouth.

Hazy or sunken eyes may signal dehydration or retained spectacles, common snake eye problems.

Sticky saliva, mouth inflammation, or discharge could point to mouth rot, also known as snake mouth rot.

Left untreated, these snake mouth problems can worsen, making annual checks and prompt care for snake mouth discharge essential.

Common Snake Health Issues

Snakes can suffer from a variety of health issues, many of which may go unnoticed without close observation.

Knowing the common illnesses, like respiratory infections, parasites, and nutritional deficiencies, helps you spot problems early and keep your snake healthy.

Respiratory Infections and Pneumonia

Respiratory infections, including pneumonia, can cause breathing difficulties in snakes, like wheezing or mouth-breathing.
