Oligomenorrhea is a disorder characterized by markedly diminished menstrual flow
or shortened menstrual period (one to two days) but with regular menstrual
cycles. Clinically, it is usually accompanied by a delayed menstrual cycle and
appears as a prodrome of amenorrhea.
Etiology and Pathogenesis
Deficient blood production or exhausted essence and blood resulting in the
insufficiency of blood sea is the cause of oligomenorrhea of the asthenic type,
and the retention of blood stasis or the stagnation of phlegm-dampness leading
to obstruction of channels is the cause of sthenic type.
Diagnosis and Differential Diagnosis
Oligomenorrhea may be differentiated from regular menstruation during pregnancy.
The former is characterized by an insidious onset, a gradual diminution of
menstrual flow and an absence of other signs of early pregnancy. The latter is
characterized by a sudden occurrence of oligomenorrhea accompanied by symptoms
of early pregnancy such as dizziness, nausea, etc., and a positive pregnancy
test.
Syndrome Differentiation and Treatment
A. Asthenic type: Gradual diminution of menstrual flow with lightcolored and
thin menses, and no distention or pain over the abdomen.
B. Blood-stasis type: Diminution of menstrual flow with dark purplish menses
containing clots and accompanied by abdominal pain and tenderness.
C. Phlegm-dampness type: Sudden diminution of menstrual flow with pink, viscous
menses.
Since the asthenic type of oligomenorrhea is more frequently seen than the
sthenic type, the therapy of nourishing essence and blood should be emphasized.
Even in the cases of blood-stasis syndrome (a subgroup of sthenic type), they
may be accompanied by astheniasyndrome, so the drugs for eliminating blood
stasis should be used with precaution in order to avoid the impairment of qi and
blood. The treatments are as follows:
A. Blood-deficiency syndrome
Manifestations: Markedly diminished menstrual flow with pale and unclotted
menses, dizziness, palpitations, sallow complexion, empty and bearing-down
