Wearing really tight pants can do some internal damage that you will not know about far a while and if there are any red marks from pants or even a bra they are too tight (wrong size, too small) ask your doctor.
I think it affects people differently. I fell upon this forum because I think my tight jeans give me constipation. I recently bought some slim jeans and am experiencing constipation. I drink a bunch of water and I don't think my body is retaining it or going to the right places. Hope you find comfort in numbers on this one. I'm going to try not to wear my jeans for three days and monitor the results.
I don't believe that wearing tight pants will cause constipation
Not at all, tight pants don't give you constipation.
