Thanks for the query to H.C.M. Forum.
Irregular bleeding , lump on the left side of abdomen ( lower abdomen ) may be due to ,
1 Poly Cystic Ovarian Disease
as in young child bearing age female this is the most common cause of irregular bleeding . Diagnosis can be confirmed by ultrasound
of both ovaries with emphasis over left side ( lump )side.
2 Next reason of this type of irregular bleeding may be due to any disease in uterus
. Diagnosis can be confirmed by ultrasound of uterus .
, excessive sleep , increase in appetite , waist line size may be due to overeating . Tension is one more cause for such symptoms.
In my opinion please consult a gynecologist and get his opinion.
Good luck. Dr. HET
