This is a quick-reference overview of the health issues Indian guinea pig owners are most likely to encounter, alongside the specific articles in this series that go into more depth on several of them.
Respiratory infections
Caused mainly by bacteria such as Bordetella and Streptococcus, respiratory infections can progress to pneumonia quickly and are one of the most urgent conditions in this species. Watch for sneezing, nasal discharge, coughing, laboured breathing, and lethargy. Treatment involves antibiotics chosen carefully, since many common antibiotics are dangerous for guinea pigs, alongside supportive care.
Dental disease
Guinea pig teeth grow continuously throughout life. Without enough hay and fibre to wear them down evenly, teeth can overgrow or develop sharp spurs that cut the mouth. Signs include drooling, a wet chin, dropping food, weight loss, and reluctance to eat. Treatment usually means trimming or filing the teeth under sedation by an experienced vet.
Gastrointestinal stasis
A slowdown of the gut, often triggered by dental pain, stress, or a sudden diet change, is an emergency in guinea pigs. A guinea pig that has stopped eating and stopped producing droppings for twelve hours or more needs same-day veterinary care.
Vitamin C deficiency (scurvy)
Covered in detail elsewhere in this series, this remains one of the most preventable conditions and shows up as a rough coat, joint pain, poor wound healing, and lowered resistance to other illness.
Diarrhoea
Usually diet-related, but can also signal infection or parasites. Treated seriously in this species since guinea pigs cannot vomit and can deteriorate quickly. See the dedicated article in this series for more detail.
Eye infections
Often bacterial, sometimes linked to respiratory disease or vitamin C deficiency. See the dedicated article in this series.
Skin and coat problems, including mites and lice
Hair loss, itching, and scabbing can point to parasites, fungal infection, or stress. Sarcoptic mange mites in particular can cause severe, seizure-like itching and need prompt ivermectin treatment. See the dedicated article on lice in this series.
Bladder and urinary problems
Bladder stones and urinary tract infections are common, particularly in a diet too high in calcium. See the dedicated article on bladder stones in this series.
Reproductive issues
Ovarian cysts are common in unspayed females over a year old. Breeding is also generally discouraged due to the risks involved, covered in a separate article in this series.
Abscesses
Infected swellings that can affect the skin, jaw, or teeth. Guinea pig pus is thick and does not drain easily, so most abscesses need surgical treatment rather than at-home management.
The single most useful habit
Because guinea pigs hide illness so effectively, a short daily check of appetite, droppings, breathing, and general alertness catches most of these problems earlier than owners expect. Combined with a vet who is genuinely comfortable treating guinea pigs, this habit does more for a guinea pig's long-term health than almost anything else on this list.
Guinea pigs do not need fruit to stay healthy, hay and fresh vegetables do the heavy lifting, but a small piece of fruit a couple of times a week makes a welcome treat. The trick is knowing which frui
Unlike most mammals, guinea pigs cannot manufacture their own vitamin C and cannot store it in the body for long. It must come from their diet every single day, and this single fact shapes a great dea
Some hair loss is completely normal for a guinea pig, but a lot of it points to something worth investigating. Working out whether the hair loss is itchy or non-itchy is usually the fastest way to nar
