Diagnosed to Gilberts in 1974 which unfortunately included two liver biopsies.
Flew short/long range - instructed light aircraft and gliders including aerobatics and still paraglide.
Stress effects the condition - mental, fatigue and physical.
Avoid alcohol although I still participate in a glass of plonk a day - but didn't drink for ten years when younger.
Turbulence and long night flights especially through the ITCZ weren't good.
A**e warming currys particularly bad.
Motocross also isn't the best idea.
Just had two days of climbing mountains to paraglide and have a typical Gilberts headache this morning.
Symptoms include headaches, sore eyes (bright lights a problem), irritability and when chronic liver ache and itching all over -(possibly caused by sweating the billirubin out through the pores).
With all of the above still managed to reach and enjoy the top of my profession but I would advise you to understand the effect of your irritability on others!
