Pleasure is a subjective word.
To my opinion, eating is pleasurable. Breathing is much more pleasurable. Just ask those lungs / asthma patients. What would they give to be able to breathe properly. Similarly, to be able to pass motion is another pleasure that we often overlooked. What is being kept inside in not healthy. What is supposed to be discarded by the body system, gets stuck in between and ended up becoming toxins to the body.
"Behold! In the creation of the heavens and the earth, and the alternation of night and day - there are indeed Signs for men of understanding" Al Quran : Surah Ali Imran 3 : 190
When we we get sick, it signals that our body cannot cope with the amount of work it has to do. Overeating, over indulging. At times we love the sweet and the aromatic, we forget to take in the goodness of plain mineral water. Of which, we need between 2 to 2.5 litres a day.
Acupuncture can also assist in getting the systems on the go, to work optimally. Primarily, the meridian point of LI4 could be used but it would not be suitable for pregnant women.
