The answer to your question is yes that can happen, because of the hemorrhoid things don't close or seal as well.
Hemorrhoids have been helped by drinking Kombucha tea. I love the stuff and drink it everyday. Try Emperors Best from spam link, I have tried many others and this is the best in my opinion. While that is helping your roid, try eating Dannons Activia yogurt to help stop the leaking.
Vitamin c and horse chestnut are supplements that make sense to use as well. Both have been noted to help with vein health.
Good luck and God bless!
