To meet personal health goals, which step involves recognizing a health problem?

The first step involved in recognizing a health problem is to seek the help of a medical professional. Seeking the help of these trained professionals would help the person become educated about the severity of the health problem and the different way/s that it can be managed or further progressed into more complicated health risks. 

As soon as a person seeks the help of a professional, this means that he/she is accepting that there is something wrong with his/her health. Acceptance is the best way to start solving health concerns because the step-by-step process of solution and commitment will arise from there.
