What works for many constipated people is total elimination of all grains, all milk products, all fried foods, all foods with Sugar added, all industrially processed foods like foods with additives, and basing diet 100% on raw vegetable, raw fruits and berries, raw fish, raw nuts, some cooked beans.
Just because it works for majority, it may not be enough for you, but if you haven't tried it, it is something to try.
water enema can help with acute constipation, to evacuate whatever hard matter is inside colon.
Do not attempt water enema daily ... you may get addicted, and you may need it the rest of your life to evacuate bowel.
Far better is to change and normalize intestinal flora by changing your diet ... as it is the intestinal flora that is the main key to preventing constipation, and also clean liver.
Learn about the Liver Flush and start flushing your liver.
Going Water Fasting with constipated colon may result in autointoxication ... and serious worsening of all of your symptoms, and total failure of your water fast.
At best, your Water Fasting experience will be a negative experience.
Fruit, berry and nut smoothies are a great way to keep your bowel soft and moving every day.
Walking or running several km per day is also a great way to keep your bowel soft and moving every day.
Also fasting on fruits, berries and nuts is a great way to prepare for a real water fasting, once you are actually ready for it.
People have ended up in hospital attempting Water Fast with constipated bowel.
Autointoxication caused by constipation can cause serious health problems, sudden loss of blood pressure, fainting, strong headaches, feeling extremely weak and sick, feeling so sick that you wish you were dead.
You don't want that. Every year someone dies attempting long Water Fast with poor functioning bowel and poor liver. This is of course the worse possible outcome, and very unlikely .... but why taking any risks ?
Few spoons of magnesium sulfate (epsom salt) dissolved in water can fix acute constipation.
Again, not something to take daily, as it may make you addicted to.
