I have a friend who suffers from chronic constipation. She's had it all her life, but it's goten worse in the last year. She has stool blockages in the colon, inability to defecate for days on end, accompanied by bloating, pain and nausea. She eats TONS of fibres, takes laxatives regularily (Dulcolax, Dulcoease), drink 1-2 litres of water a day but still it doesn't help. Eventually, she does void, but this is preceded by days of painful constipation.
She's been to the doctor and a specialist, it didn't solve the problem; enemas and surgical-grade laxatives had only minor effects. Anyone ever heard of this, or know someone who has this?
