If your bowels are not moving at least once a day then this is considered constipated.
Here are a few tips to help with constipation;
Identify and remove food allergies
Water - drink adequate filtered water
Salt- mix 1 tablespoon of sea salt in 15-170mls of water and drink. This should help the bowels to move. This can be done for 3-4 days then decrease it to half teaspoon daily as maintenance. NB do not use regular table salt, only good quality sea salt.
Oil - get adequate oils from your diet or supplements. Consider oily fish, sesame, sunflower and other seeds, good quality olive oil, flax seed oil, evening primrose oil, fish oils.
Bulk- good quality fibre from vegetables, fruit or other sources of fibre such as Premier Research Labs Galactan supplement which is high in fibre, holds water in the bowel and ferments to butyrate to feed GUT flora and easily dissolves in water for a pleasant drink.
If the above suggestions don't help you may need a thorough evaluation to get to your underlying cause of constipation.
