Bleeding gums in guinea pigs is not normal and usually indicates an underlying dental, nutritional, or systemic issue that needs prompt care. Here’s a full guide 👇
🩸 Causes of Bleeding Gums in Guinea Pigs
1. Vitamin C Deficiency (Scurvy)
The most common cause.
Guinea pigs cannot synthesize Vitamin C, so deficiency leads to:
Bleeding gums
Loose teeth
Swollen joints
Poor wound healing
Lethargy and pain
🩺 Treatment:
Supplement Vitamin C:
25–50 mg/day orally (as advised by vet).
Use chewable tablets, liquid drops, or C-rich foods (bell peppers, kale, parsley).
Ensure the diet includes fresh vegetables daily and guinea pig pellets fortified with Vitamin C.
2. Dental Problems
Overgrown or misaligned teeth can cause:
Gum trauma or ulceration
Inability to eat properly
Drooling (“slobbers”)
Weight loss
🩺 Treatment:
Vet trimming of overgrown incisors/molars under anesthesia
Soft diet until healed
Address underlying malocclusion causes (e.g., low hay intake)
3. Injury or Foreign Object
Sharp hay pieces, cage bars, or rough pellets may injure gums.
🩺 Care:
Gently inspect the mouth (if safe).
Rinse with diluted chlorhexidine or saline.
Remove sharp bedding or toys.
4. Infection (Gingivitis, Abscess)
Bacterial infection from trapped food or poor dental alignment.
May cause swelling, pus, and pain.
🩺 Treatment:
Vet cleaning or abscess drainage.
Antibiotics safe for guinea pigs (e.g., enrofloxacin or trimethoprim-sulfa).
⚠️ Avoid penicillin, amoxicillin, or cephalosporins — they are toxic to guinea pigs.
5. Systemic Illness or Toxin Exposure
Liver disease or clotting disorders may cause spontaneous bleeding.
Rat poison (anticoagulant) exposure can lead to bleeding gums and nosebleeds.
🩺 Treatment:
Emergency vet care.
Vitamin K and supportive therapy.
🥦 Supportive Home Care
Feed soft, fresh vegetables and timothy hay for gentle chewing.
Avoid hard pellets or rough items.
Provide Vitamin C daily (no skipping days).
Keep cage clean and dry to prevent infections.
⚠️ When to See a Vet
Continuous bleeding or swelling
Difficulty eating or drooling
Weight loss or lethargy
Blood around mouth or in droppings
Prompt dental or lab evaluation is needed — guinea pigs hide illness until it’s advanced.
✅ Summary
| Cause | Key Sign | Treatment |
|---|---|---|
| Vitamin C deficiency | Swollen, bleeding gums, weakness | Vit C supplement, fresh veggies |
| Dental overgrowth | Drooling, weight loss | Tooth trimming, diet correction |
| Injury | Localized bleeding | Saline rinse, remove sharp objects |
| Infection | Pus, pain | Vet antibiotics |
| Systemic/toxin | Widespread bleeding | Emergency care |
