Many people don't realize that as they get older they often become intolerant to milk products (except for yogurt or goats milk). Even some vegetables that didn't cause gas when you were younger begin to cause gas (and pain) as you get older. Then if you have adhesions the pain gets really bad and you don't know why. It's often because of the food your eating. Also, overeating can cause pain as well.
One more thing: Have you noticed how old people prefer to eat their big meal at noon? It's because as we get older our bodies (and bowels) become sluggish as the day wears on. When older people eat a big meal at night they feel full all night, have indigestion, bloated, etc. It's worse for those of us with adhesions. Don't eat a big meal at night! All my bowel obstructions have been at night!
Once I learned to take BEANO and Lactase (vegetable and milk enzymes) and Gas-X, I no longer need pain pills!! Besides, pain pills are so constipating and that's the last thing anyone with adhesions needs! Take a stool softener at bedtime with lots of water. ~ Kathleen
