Thank you for the query.
No, its not from disc disease
. Only some serious spinal cord
injuries can cause chronic constipation
but typical disc herniation with some slight symptoms should not cause constipation.
Chronic constipation can be caused by bad diet (low fiber and mineral water intake), hypothyroidism
, medicines (antidepressants and Ca-blockers), inflammatory bowels diseases.
I suggest you to start with diet change (increase fiber rich products and mineral water intake), start probiotic intake. If it wont help in a week or so, please visit your doctor. Stool test, stool culture test, thyroid tests should be done at first.
In case of any doubts, colonoscopy
Hope this will help.
