Spicy foods and hemorrhoids

Is it true that eating spicy foods too much can cause hemorrhoids? That's what i heard from my aunt the other day. She said her husband is suffering from hemorrhoids and apparently her husband loves to eat spicy a lot. Now he is undergoing hemorrhoids treatment. Well i think i have to research and study about hemorrhoids, my husband loves to eat spicy foods too and if it's true then i have to warn or remind him to eat spicy foods in moderation before it' too late.
