Perhaps you could tell us what the signs are that led your vet to suspect ovarian cysts and if another possible diagnosis has been offered?
Several people here have had pigs with ovarian cysts and other conditions involving the reproductive system. I´m sure they´ll be willing to help if you have any specific questions.
Unfortunately the outcome is not always good, these are serious health problems for a guinea pig.
Female guinea pigs may suffer from cystic ovaries as they age. It is estimated that over 75% of female cavies between 1.5 and 5 years of age have them. The cysts, which develop spontaneously, can be of varied sizes, and there may be one or several, on one ovary or both. A breeding sow may show decreased fertility. Pet guinea pigs may develop bilaterally symmetrical hair loss over the trunk and flanks. Ovarian cysts can be diagnosed through ultrasound. Medical treatment with chorionic gonadotropin injections may be attempted, and cysts may be drained with ultrasound-guided needle aspiration, but these treatments will usually only result in temporary improvement and the cysts may return. Surgery to remove the affected ovaries is curative, and usually a complete ovariohysterectomy is performed (commonly called a "spay").
If it is mites, all pigs must be treated. Just treating her may determine if it is mites (she should show improvement) but if it appears she does have them, you´ll have to go back and get everyone treated as the other pigs will be carriers.
Good luck. The ultrasound is definitely a less invasive option.
Where is the hairloss? What makes you think her hormones are out of whack?
And usually cysts can be palpated unless they are very close to an organ.
I think cysts are more likely to appear after the age of 3. And I believe Josephine as well as Vicki of Jack Pine Guinea Pig Rescue also haven´t noted as high a number of cystic pigs as the med texts claim as a norm.
I think we discussed this in another thread. Try doing a search on ovarian cysts.
Snowflake was about 2 1/2.
The young one with the cysts is also hyperthyroid and has heart disease. Doesn´t rain but it pours.
We just had an ultrasound recheck on a pig with typical hair loss that would appear to be hormone related. Not a cyst in sight. Another pig we had ultrasounded for cysts(bilateral hairloss) turned out to have Cushings Disease. Not cyst in sight.
