Seasonal allergies and vaginal discharge can actually be related.
“Once the seasonal allergies hit, a lot more people have vaginal discharge,” says Dr. Loanzon. So your discharge in the summer may not indicate a vaginal infection, but rather, just a reaction to the environment. “The same way that [you] have itchy eyes and scratchy throats, you can also have itchy vaginas,” she continues. To err on the side of caution, it’s always safe to check with a doctor.
If your vaginal discomfort is purely allergy related, it can be treated with antihistamines and decongestants, just like your more standard seasonal allergies.
