Health Risks with Pineapples & Guinea Pigs

Even though pineapple is one of the better fruits for guinea pigs, you’ll want to be careful with how much pineapple you’re feeding them. If you feed them large quantities of pineapple it can lead to some major health issues.

Too much pineapple can lead to:

  • Kidney problems. Kidney problems are actually very common in guinea pigs. Pineapple has a large amount of calcium in it and a high amount of calcium can lead to kidney stones as guinea pigs have a hard time breaking down all the excess nutrients.
  • Diarrhea. Guinea pigs have a weak digestive track compared to other small animals. They can’t handle large portions of many foods and they have a hard time processing sugar. Diarrhea can become a serious problem if untreated and cause dehydration making your guinea pig even sicker.
  • Obesity. For any food, overfeeding your guinea pig can lead to weight issues and unhealthy lifestyles. Guinea pigs can gain weight very easily and being overweight will diminish their health greatly and lead to many health problems such as heart issues, high blood pressure, arthritis and more.
  • Bloating. Bloat is the formation of gas in your guinea pig’s stomach and can occur from overeating. Bloat can be very painful and even deadly to guinea pigs if it hinders their ability to breathe.
  • Mouth sores. Since pineapples are more acidic than other fruits it can lead to irritation in your guinea pig’s mouth which can turn into lesions. If your guinea pig has lesions they will be less likely to eat which can cause issues with their weight and overall health. You’ll likely have to provide your guinea pig with a liquid diet and should talk to a vet immediately.
