Hello, Thanks for the query. Constipation can be relieved by following measures : 1) Increase intake of green leafy vegetables and salads as well as fruits daily, 2) Drink enough water every day. 3)Avoid bakery items and junk foods, pastries etc. 4) EVery morning consume a whole glass (250 ml) of hot water as soon as you get up, preferably with half a lemon in it. If these measures do not help, then may take a preparation containing Lactulose 10 to 15 ml at bed time. As regards itching at the anus, most often it is due to a helminthic infestation called Enterobious vernicularis.(pin worm). This can be treated by taking Albendazole 400 g once and should be repeated after 10 days. Plus all the inners and bed sheets to be washed in boiling water. Thanks
