How about the Saturn in the 6 house in Sagitarius?
Izzy, Saturn in the 6th House of health? In Sag? Can't be that bad if nicely aspected. I have no idea what else is in your chart so I would hesitate to offer advice.
But having said that and its almost home time so I can visit my favourite forum, basically Saturn solidifies what the House represents or rules. Saturn is organisation, structure and so we look at our bones and skeleton for that in the body. Bones and skeletons add structure to our body, they old us upright and give us shape, Saturn qualities.
What we worry about in Health is the other qualities of Saturn. Psychologically he can be depression, or sadness, or physically he can be structural illness, but then, EVERY planet can be illness if poorly aspected in the natal chart or triggered by transit.
If I had Saturn in my 6th House I wouldn't worry too much, it could be a positive motivator to structure your healthy living. In fact, we could say Saturn in the 6th House in Sagittarius suggests that he motivates you to exercise.
Saturn in the 4th in Virgo, for Summer Joy, suggests that your home life and your childhood are structured and ordered, you love to serve your family and your children. Negatively your childhood was excessively structured and discipline ruled. You had to clean your plate before you left the table, and remove your shoes before entering the house.
Every planet has a good side and a bad side, we always consider them as part of the whole chart, not singularly like I just did.
Saturn isn't always bad, he is often set up with bad press yet he doesn't always deserve it.
