How long does bloating take to go away i've been bloated for like three weeks very constapated what do i do had kub said i had fos?

Bloating: It sounds like your bloating may be related to constipation. The bloating will not go away until the constipation is relieved. I would start with a high fiber diet, 64 ounces of water a day, regular exercise and possibly a stool softener medicine. If not resolving, their could be another medical cause for your constipation and bloating and further testing could be needed.

Treatment: Try to treat the constipation. There are many otc remedies. As that resolves, so will the bloating.
