Ketu is in 6th house in Sagittarius

As a Jyotish astrologer, I would interpret Ketu's placement in the 6th house in Sagittarius sign to indicate a focus on health, service, and work. Ketu is known for its detachment and may create a desire to withdraw from the material world in some way, which can lead to a spiritual or philosophical approach to health and service.

The 6th house rules over health, disease, and conflict, so there may be some challenges related to these areas of life. But with Ketu's presence in this house, there is a potential for healing and transformation through developing a deeper understanding of the true nature of health and wellbeing.

Additionally, Sagittarius is a sign that is associated with travel, higher education, and philosophy, so these themes may come up in relation to the work or service you undertake. You may find that you are drawn to service or work that involves cross-cultural exchange, or that requires a broad understanding of different perspectives.

Overall, Ketu in the 6th house in Sagittarius can be seen as a call to service and healing that is rooted in a holistic and philosophical approach to health and wellbeing.
