Hi thanks for contacting HCM... Noted you are mentioning white thread coming from anus in stool... So here it looks like larva of parasite like hook worm or round worm Get your stool examination for it... For it albendazole given.... If stool show pus cells then antibiotic needed as that is suggesting bacterial infection..... Meanwhile take more water. Avoid fried and fatty food in excess. Chamomile in tea good for constipation. Whole grain, wheat bran , apple , carrot like fiber food taken more.... Blueberries loaded with fiber and vitamin c . So can be taken... Peaches fruit rich in fiber , iron , vitamin c and potassium ...so help in proper digestion... Take care.... Dr.Parth
