Hi, Yes, laxatives are advisable for the symptomatic relief of constipation. Scientific studies have shown that sleeping on the left side lets gravity help intestinal contents get from the small intestine to the large intestine and then to the lower colon on the left side. This increases the likelihood of having bowel movement first thing in the morning. However in addition you must take lot of dietary fibers in the form of vegetables or fluids, increased physical activity, adequate fluid intake, avoid carbonated soft drinks and high caloric foods which can prevent constipation. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Mohammed Taher Ali
