**Direct answer:** Take psyllium with the full amount of liquid stated on the label and never swallow it dry. Ask a pharmacist how to space it from medicines, and seek help for chest pain, vomiting, trouble swallowing, or breathing problems.

## Use fiber as one part of the plan

Fiber can support bowel regularity, but symptoms also depend on food, fluid, medicines, activity, and health conditions. Make one gradual change at a time so its effect is easier to judge.

## How quickly should fiber be increased?

Increase it gradually rather than making a large change at once. This gives the digestive system time to adjust and can reduce gas or bloating.

## Does fluid intake matter?

Yes. Follow the supplement label and drink enough fluid for your health needs. Ask a clinician first if you have a fluid restriction.

## When is self-care not enough?

Get medical advice for blood in stool, persistent or severe abdominal pain, vomiting, unexplained weight loss, swallowing trouble, or constipation that does not improve.
