Does Hemorrhoids Go Away

Never hemorrhoids disappear on their own?
I'm 16 and I have external hemorrhoids. I have constipation, because I do not eat very well. They never hurt and are pretty small, but I do not have them, it seems crude. They are not very big, I bought Preparation H ointment yesterday, it works well? I do not really know what to buy because I do not need anything for relief because they do not cause of me ill, I want something to reduce them. Will I need surgery for my hemorrhoids to go away forever? Then they went go on their own if I start to eat more fruits and vegetables? If yes, how long can it take for them to be gone?
Have you thought of eating well then? If you are constipated for the rest of your life, you have hemorrhoids for the rest of your life, and they will get worse and worse and cause you severe pain. So, change your habits now while you're young enough. Do not be stupid.
