Lighter after use Perhaps you are thinking now: but after taking a laxative pill I did lose weight. This may seem true, but it is not. Because the laxatives cause you to lose a lot of moisture and you seem to have lost some weight. However, a fluid deficiency is anything but good for your body. Threats Losing weight with laxatives is a very dangerous way to lose weight. For example, it can cause dehydration and you even run the risk of permanently damaging your intestines. It can also be harmful to your kidneys. When you combine laxatives with little food, you also miss a lot of nutrients and this is anything but good for you. Painful Taking laxatives is not painless. You will suffer from extreme cramps that are quite dominant. You may also experience this after going to the toilet. Keep in mind that you really have to run to the toilet a few times a day. Diet tea People do not always notice it, but there are many different slimming teas that also contain laxatives. So don't be fooled by the word ' slimming tea ', because it is anything but good for you.
