When considering when health issues can occur in women, it is important to define "woman." We tend to think of women as adult females. This means that a young woman who has reached puberty is entering womanhood. Therefore, it stands to reason that a young woman can have health issues.
The most common health issues that women seek care for include the following: problems with their menstrual cycles; contraception, abortion; anorexia, anemia; pre-conception counseling; infertility; pregnancy (low and high risk); sexually transmitted infections; cancers of the reproductive system and breast; perimenopause; menopause; sexuality issues; sexual dysfunction; gender concerns; abuse; heart disease and many other chronic health issues such as diabetes, fibromyalgia, lupus, etc. Any of these health issues can occur at any time in an adult woman's life.
