Please give your date of birth, time of birth and place of birth to discuss. For Taurus lagna, Jupiter may become 7th lord or 8th lord or 9th lord. Sometimes there may not be any house in Sagittarius.
In Placidus system of house divisions, it may happen.
Jupiter is the 8th house lord in 6th house. A planet gives its results by location, aspect, ownership, its star lord. The result is : 6th house results can be expected through 8th house and Jupiter. Unless 6th house is connected to 1st house illness will not be there. 6th house deals with servants, pet animals and maternal uncle. 8th house is 3rd to him. So your maternal uncle will have longevity and go on tour or some other communication. As Jupiter is a benefic, he or your servant goes on a short tour.
So please provide the details and discuss.
