Chakras are part of your energy body. The energy body is heavily interconnected with your physical body as well you as a consciousness (mental, subconscious etc.).
Physical, mental, psychic etc. disorders can have Millions of different origins and causes. Just fixing the Chakras, which are only a small part of the whole energy body, is not a universal solution.
I recommend you browser the internet on the many bodies of the human body and how they are interconnected with each other. And then still, overall health is a super complex interaction of Millions of aspects working together. The energy body is as complex as the physical body. And just to understand the physical body in its basic functions, one requires to have quite some knowledge about biology and chemistry.
If there are any universal regulating factors that oversee all the layers and all other factors, then it would be one’s Subconscious Mind and Higher Self.
