These are gases build up during nite time, as we devour our
foods, our digestive system goes to work, alots of juice, enzyme,
and digestion take place, some of us are more prone to produce more
gastirc gases than others, or simply, it could be taking too much
gaseous oily stuff. Therefore if can, do not take food at nite,
younger peoples may not suffer from it, cos they have a better
digestive engine, however as they grow older, illness or sickness
may fall in. For older peoples, they should not over eat. Either
you are young or old, keep a good proper diet, if needed, take
light food or alkaline stuff like warm milk at nite to subdue to
gastric formation that can trap the gases in a bloating condition
resulting in abdominal pain.
