Scurvy may sound like a problem for old-time sailors, but it’s still common in pet guinea pigs. The good news is that it’s easy to prevent and usually treatable when caught early. This guide explains the causes and symptoms of scurvy in guinea pigs, how it’s treated and how to keep your pet healthy.
The Short Answer: Scurvy is a vitamin C deficiency. Guinea pigs can’t make vitamin C, so they need it from food every day. Signs include stiffness, swollen joints, a rough coat and bleeding gums. A vet can treat it with vitamin C supplements and supportive care, and most guinea pigs improve within days.
What Causes Scurvy?
Scurvy develops when a guinea pig doesn’t get enough vitamin C for about 2 weeks or longer. Common reasons include:
- Old pellets. Vitamin C in pellets breaks down over time.
- Feeding rabbit pellets, which don’t contain added vitamin C.
- Too few fresh vegetables, or vegetables low in vitamin C.
- Poor appetite from dental disease, illness or stress.
- Higher needs during pregnancy, growth or illness.

Symptoms of Scurvy in Guinea Pigs
Vitamin C is needed to make collagen, so scurvy affects skin, joints, gums and blood vessels. Signs include:
Early signs
- Less active than usual
- Rough, unkempt coat
- Eating less
- Mild weight loss
Later signs
- Swollen, painful joints, especially in the legs
- Limping or walking with a stiff, “hunched” gait
- Squeaking in pain when picked up
- Bleeding gums or loose teeth
- Bruising or small spots of bleeding under the skin
- Diarrhea
- Slow wound healing
- Increased risk of infections, such as respiratory disease
Guinea pigs with scurvy are also more likely to develop other illnesses, because vitamin C supports the immune system. The Merck Veterinary Manual lists hypovitaminosis C as one of the most common nutritional problems in guinea pigs.
How Vets Diagnose Scurvy
There isn’t a simple home test. Your vet will:
- Ask about your guinea pig’s diet, including the type and age of pellets.
- Examine joints, gums, teeth, coat and weight.
- Sometimes take X-rays to look at bone and joint changes.
- Check for other illnesses, since scurvy often happens alongside dental or respiratory disease.
Treatment
Most cases respond well to:
- Vitamin C supplements, given by mouth or injection at a dose your vet sets.
- Pain relief for sore joints.
- Assisted feeding if your guinea pig isn’t eating well.
- Treatment of any other problems, such as overgrown teeth or infection.
- Diet changes to prevent it from returning.
Many guinea pigs perk up within a few days of starting vitamin C. Joint and bone changes take longer to heal.
Myth vs. Fact
| Myth | Fact |
|---|---|
| “Pellets alone provide enough vitamin C.” | Pellets lose vitamin C over time. Fresh vegetables are essential. |
| “Vitamin C drops in water are the best way to supplement.” | Vitamin C breaks down quickly in water, and drops can make guinea pigs drink less. |
| “Only old guinea pigs get scurvy.” | Any age can be affected. Young and pregnant guinea pigs need more. |
| “If my guinea pig eats lettuce every day, it’s fine.” | Iceberg lettuce has very little vitamin C. Bell peppers and leafy greens are better. |
How to Prevent Scurvy
- Feed about one cup of fresh vegetables daily, including vitamin C-rich bell pepper.
- Use a guinea pig pellet with stabilized vitamin C, and check the date.
- Store pellets in a cool, dark, airtight container.
- Never substitute rabbit food.
- Weigh your guinea pig weekly to catch appetite changes.
- Check teeth regularly, since dental pain can stop eating.
When to Call Your Vet
Call your vet soon if your guinea pig:
- Has a rough coat or seems less active
- Is losing weight
- Walks stiffly or limps
Get same-day care if your guinea pig:
- Has stopped eating
- Cries out when touched
- Has bleeding gums or blood in the urine
- Has breathing problems. See our guide to respiratory infections in guinea pigs.
Frequently Asked Questions
How quickly does scurvy develop?
Signs can appear after about 2 weeks without enough vitamin C, sometimes sooner in young or sick guinea pigs.
Can scurvy kill a guinea pig?
Yes, if it isn’t treated. Severe deficiency weakens the immune system and causes serious pain and bleeding. Early treatment is very effective.
Can guinea pigs recover fully from scurvy?
Most do, especially with early care. Some joint changes may take weeks to heal, and a few guinea pigs have lasting stiffness.
