Final answer:
Complementary medicine is used alongside conventional medicine, alternative medicine replaces conventional medicine, and integrative medicine combines both approaches.
Step-by-step explanation:
Complementary medicine refers to the use of non-mainstream approaches in conjunction with conventional medicine, whereas alternative medicine is used in place of conventional medicine. On the other hand, integrative medicine combines both mainstream medical treatments and complementary approaches to provide a comprehensive approach to healthcare.
For example, if a patient with chronic pain is receiving conventional medical treatments like pain medications, they may also explore complementary approaches such as acupuncture or chiropractic care to improve their overall well-being. In contrast, a patient who chooses alternative medicine may opt for herbal remedies or homeopathy instead of conventional treatments.
It's important to note that while complementary and integrative medicine are often used alongside conventional medicine, they should never replace evidence-based medical treatments for serious conditions.
