I can't advise u on continuing or stopping ur fast at this particular case (coz u do need to take care of the famiy).. I think u need to wait for other suggestions on this forum and act according to what is around u. :)
Look I also have galbladder issue (do not remember how it is called in English).. it is when the wall of the bladder is thickened (and actually on ultra sound, as in my case, they do not see stones). I asked Chris on this forum and he said that if the wall of galbladder is thicker than it supposed to be then it is galstones and he wrote: Try 12 to 15 days but rest most if not all of the time. You may need to clear any sludge from your bile ducts and fasting will do the trick... Yes a Liver Flush is fine beforehand. Carrot juice (fresh and organic cleans and rejuvenates the Liver... up to 6 pints per day. up to and only carrot juice. you will most likely get more benefit from the carrot juice. at least 6 days just on carrot juice and only carrot juice. Carrot juice does not contain Vitamin A only Beta-carotene (its precursor) or what comes before the liver transforms it into the Vitamin. This is regulated by the liver itself. So no you will not overdose on Vitamin A.... Yes you could water-fast but the carrot juice is a better option for you in my opinion. Only freshly extracted organic carrot juice.
Chris: all disease and health problems stem from an impaired Liver, including your gallbladder problems such as sludge... but your gallbladder is fed by the liver as that is where your bile comes from.........about 3 litres of it per day. Clean out and rejuvenate your Liver first... REST is vital throughout with no worries.. Of course it will help. of course. read the link I sent you.
So here we go! Perhaps it wil help u considering u can't fast longer... Just make sure u eat plant based diet after ur fast is over.
Also I do not remember i read it in above mentioned link or collected other info related to drinking organic carrot juice for those days... so it is advised to drink a glass of raw carrot juice every hour eveny while u are awake.. so that ur liver will repare itself smoothly may be.
