I had chronic constipation for two decades. Now I drink lots of water, use psyllium and acacia fiber, and soaked chia seeds. I also take magnesium citrate, magnesium glycinate and take walks.
Eating lots of fruits and veggies, whole grains, and legumes helps. An apple a day really works!
I take trulance for it and a natural laxative.
Miralax, drinking, prune juice. and a adding extra fiber to your diet.
