Thanks a lot sir for the reply..The transit of Saturn over natal Jupiter since October/2017 has caused health issues to your husband. The situation of Saturn in the fifth house always causes trouble relating to job.
In the natal chart Saturn is in Swati constellation (nakshatra) of Rahu and opposite the Moon, Venus and Mercury. Therefore during the major-period of the Moon the trouble has started.
He will take one more year to improve.
Will write in short.
Saturn is not harmful though this is causing illness, job obstacles.So just relax he will be alright.Saturn is weak for few houses including 6th,5th and 10th.Till end of this year things might be upseting you and then saturn antardasa will skip.
