If excretion does not take place,there will be accumulations of toxins in the body which may affect the body system and may kill living cells.Toxicity may also occur in the body system which may be very dangerous to it.So excretion is neccessary.
What Would Happen If Excretion Do Not Take Place?
That answer would have to depend on how long you have been without excretions. I can be a very serious problem. You should have movements preferably everyday. You have heard, maybe, that you need to drink 8 glasses of water per day. It is true and very important. Also, your food must contain a large amount of fiber to help the bowel work properly. Laxatives or an enema could help you overcome this situation, but it is not advisable to do so on a regularly basis. Your situation could become so sever, if allowed to continue,that you would have to go to a doctor or hospital. So you must take action right away.
