jaundice, pruritus, (it is autoimmune) other autoimmune conditions AMA

Constipation treatment? Treatment for opioid induced constipation?

Conservative measures - increase fibre and fluids, exercise, balanced diet If conservative measures don’t work: - > 1st line = bulk forming laxatives ISPHAGULA/PSYLLIUM, METHYLCELLULOSE - > if unsuccessful, add an Osmotic laxative MACROGOL(polyethylene glycol) first then LACTULOSE DO NOT prescribe bulk forming laxatives for opioid induced constipation.
