How does a laxitive work?
laxitives are made for people who can not poop and for people who want to lose weight even though using them to lose weight isn't healthy at all. The concept behind the role of laxatives in reducing weight is that they increase bowel movement. By stimulating the rate of bowel activity, the laxatives prevent the large intestine from absorbing food, where normally, the maximum food gets absorbed. This means that laxatives conduce rapid movement of food from bowel to the exterior, before absorption of food can take place. Regular intake of laxatives affects fat absorption in the body, resulting in diarrhea. The food ingested passes through the body without getting absorbed, thereby preventing any weight gain.
Should you take water with laxatives?
You shouldn't eat for a while, because the laxatives will be trying to rid your body of whatever food and substance it has in the stomach. Eating soon after taking the laxatives would only complicate the process, and possibly make it more painful.

What are the functions of the small intestine?
The main and most important function of the small intestine is * absorption. While digestion of food practically starts in the mouth (mechanical digestion, enzymatic digestion), and continues in the stomach (digestion of proteins), the small intestine finished the digestion (others then protein), and absorb everything the body needs. Leaving the large intestine to deal with the absorption of water, and as a place for some bacterial activity (certain vitamins). The small intestine also * transport received the chime from the stomach, its peristaltic movement further it (what's left of it) down to the large intestine. It secrets * enzymes, digestive juices necessary for the digestion/absorption/pH regulation. * It receives other necessary enzymes, chemicals from other organs (bile ect.) which it utilises in the above process.

Why is lactase not found in stomach or large intestine?
this is because Lactase activity increase at a pH of 7 and 8 but at a pH of 7, the activity is maximum. At a pH above 7, the activity is decreasing. At a pH of 1 and 2, Lactase is inactive. Therefore, Lactase work best at a pH between 7 and 8.
Why is intestinal bowel syndrome called a functional disorder?

What do large intestine do?
The large intestine is about 1.5 m long and consists of the caecum, appendix, colon and rectum - which are distributed in the abdominal cavity. The large intestine is the part of the digestive system where waste products from the food you eat are collected and processed into feces. A major function of the large intestine is to recover water used in processing the food, reducing the waste to a drier form. It also absorbs certain vitamins, some of which are released by the activity of helpful bacteria. (see also the related link)
How do you lose weight on laxatives?
You don't. The only weight you lose with ex-lax will be water weight, which you'll eventually gain back. Taking laxatives is dangerous, can cause dependency, and won't help you to lose weight.
