The short explanation
Psyllium husk, often called isabgol, is a natural fibre supplement. It works by absorbing water and making stools softer and bulkier, which helps them move through the bowel. For many people it is considered a gentle option for ongoing constipation when used with enough water. Regular use is generally considered acceptable for many people, but it is still worth asking a doctor if you have needed it for a long time. Constipation can sometimes be caused by low thyroid, diabetes, certain medicines, pelvic floor problems or bowel conditions, and these need their own attention. Increasing fibre from food, drinking enough water, staying active and a regular toilet routine can reduce how much you depend on it.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Always take fibre supplements with plenty of water. Without enough fluid, they can make constipation worse or, rarely, cause blockage.
- Some people get bloating or gas when they start fibre; increasing slowly helps.
- A new change in bowel habit, bleeding, weight loss or pain needs a doctor's review.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether regular isabgol is right for you or what is causing your constipation. A doctor can advise.
