Not voluntarily. Nine months ago, I was struck by a sudden acute pancreatitis shock and was interned urgently in a hospital. The first provision taken by the surgeons was to put me under a treatment that included a six-day fasting to protect the pancreas that was irritated. I was later operated to unblock my common bile duct and two or three days afterwards, despite my post-fasting and post-operative condition, I found it slightly easier to walk along corridors in the hospital. The positive effects lasted me for about a month with a feeling to have achieved a slight permanent improvement. On informing this to my neurologist, a young and bright doctor working also as a researcher, she told me that the improvement might have been a result from both the fasting and the easier digestion of food thanks to the free movement of bile and enzymes through my bile duct. I learned two things, therefore, that fasting and food metabolism do have a bearing on my PD.
