Life Coach or Health Coach…?

I’m certified as both a Life and Health Coach. I promote myself as a Life Coach who focuses on the integrated relational dynamics of life. Helping my clients realize how the individual parts of life affect the whole. I help bring all the parts together to make them whole. Can this niche be used to help someone with one of the major diseases (diabetes, heart disease, high cholesterol etc.) I don’t want to confuse people but also don’t want to miss the opportunity to help those who can benefit from my knowledge. As a Life Coach, can I help someone with diabetes?
