Inquiry regarding field-specific checklist when considering multiple procedures simultaneously

I am considering multiple procedures simultaneously. Please provide a checklist of essentials and contraindications for each field.

Plastic Surgery (anesthesia, quitting smoking), Dentistry (implant bleeding, antibiotics), Ophthalmology (discontinuing contact lenses before LASIK, pain management), Dermatology (timing of laser treatment, UV rays), Hair Loss & Obesity (nutritional status, medications), Nutritional Supplements (pre- and post-surgery contraindications, recommendations). Please also provide tips on choosing a hospital.
