Secondary dysmenorrhea refers to
menstrual pain of new onset in a woman previously void of menstrual pain
or the presence of worsening menstrual pain over a period of time.It
is secondary to an underlying pelvic disease.
Causes
These include diverse set of diseases or disorders affecting the uterus (womb), adnexea and the pelvic cavity. They are:
Presentation
The
presentation varies and depends on the underlying disease condition. It
typically presents as any other pattern of menstrual pain different
from that described for primary dysmenorrhea. It has no singular pattern
of presentation and may occur at any phase of the menstrual cycle as
well as during menstruation and unlike primary dysmenorrhea that
typically appears few months after menarche,
it may appear at anytime during the reproductive years. It may also
present as worsening primary dysmenorrhea or as a new onset of cyclical
lower abdominal pain felt in a woman who never experienced primary
dysmenorrhea. With multiple possible causes, its severity varies with
its cause and resolution of symptoms usually occurs following the
treatment of the underlying cause.
It
may also present with other symptoms typical of the underlying cause of
the dysmenorrhea. For example, secondary dysmenorrhea may be associated
with heavy menstrual bleeding in uterine fibroids, adenomyosis and in women with IUCD. Similarly, women with uterine fibroid and adenomyosis may present with a lower abdominal swelling and an abdominal mass on physical examination while those with PID may present with an offensive vaginal discharge associated with fever. Endometriosis another
common cause of secondary dysmenorrhea often present with severe
symptoms associated with painful intercourse on deep penetration (dyspareunia).
Diagnosis
This
involves taking a detailed history, performing a thorough examination
and employing the use of necessary investigations. Usually from the
clinical history, it is easy to differentiate primary dysmenorrhea from
secondary dysmenorrhea, but not always so from the different causes of
secondary dysmenorrhea. Specific presentation, investigations and
treatment of the various causes of secondary dysmenorrhea will be
discussed in detailed in respective articles written about them. In the
main time, basic investigations necessary for the diagnosis of secondary
dysmenorrhea are discussed below.
Differential diagnosis
This includes primary dysmenorrhea as well as any of the above listed causes of secondary dysmenorrhea.
Investigations
Investigations commonly done are;
Abdominal ultrasound:
This is important in making a diagnosis of uterine fibroids,
adenomyosis as well as to diagnose the presence of ovarian masses in
suspected cases of endometriosis.
Laparoscopy: This is the gold standard of diagnosis of PID, endometriosis and pelvic adhesions.
It can also be used to view first hand, the presence of any other
pelvic diseases such as the uterine fibroids and ovarian cysts. It has
the advantage in expert hands to be used for the treatment of many of
the causes of secondary dysmenorrhea.
Chlamydia and Gonorrhea screening tests: Patients with vaginal discharge and those with symptoms suggestive of pelvic inflammatory disease (PID) should be screened for Gonorrhea and Chlamydia infection. These include antibody tests for Chlamydia and endo-cervical swab M/C/S for Gonorrhea. If present other STDs should be investigated and all contacts traced to disrupt the chain of transmission.
Treatment
The
definitive treatment of secondary dysmenorrhea is by the treating its
cause. However, many of the above listed approach for the treatment of
primary dysmenorrhea may help to reduce the symptoms till a definitive
approach of treatment is available or desirable. For example, patients
with uterine fibroids, endometriosis and adenomyosis presenting with secondary dysmenorrhea may benefit from the use of NSAIDs, OCPs or the insertion of Mirena for
the relief of their menstrual pains pending their definitive management
with surgery. For treatment of specific causes of secondary
dysmenorrhea, kindly please see a gynaecologist.
