How laxatives work?
In: Biology
Some like psyllium husk are pretty just fiber, which makes the stool bigger and easier to push out.
Others are salts (most commonly known one is table salt), which are compounds made of a positively charged atom and a negatively charged atom. These compounds draw water to them, for complex chemistry reasons I don’t want to get into (I have no idea what they are), and some of them arent well absorbed by the body and sit in your intestines with the stool, which draws water to it and makes it liquid.
Others are stimulants, which are compounds that irritate the nerve cells in your butt causing a natural muscle movement known as peristalsis, which is where muscles contract in order to push stuff out your butt.
