I am from Europe, Mediteraninan part of it. I believe olive oil has so many great uses. I used to suffer horribly from constipation. Eating vegetables with a good dose of olive oil (your husband can even drink the leftover olive oil from the plate) really helps. Did you try dates and prunes?. That may help. I also experienced good results with hot peppers (it stimiulates your metabolism) - like chilli peppers. Your husband should also drink a lot of water or green tea. Don't let him drink too much soda drinks, that will make the situation worse. Please don't get angry at him, that won't help. Maybe you can try stool softerners. Don't give him the traditional cleansing pills - they can negatively effect the lining of the stomach. I also used to use the gell like suposatories - they work like magic, they are more natural and won't hurt his stomach. Let me know if any of my suggestions work.
The best of luck to you guys.
