The following are the most important diseases or complications that can be caused by oligomenorrhea:
Neoplasms – Tumor diseases (C00-D48).
- Endometrial cancer (cancer of the uterus) – chronic anovulation (failure to ovulate) increases the long-term risk of endometrial hyperplasia (thickening of the lining of the uterus) and endometrial cancer.
Psyche – Nervous System (F00-F99; G00-G99).
- Problems in the partnership, for example, due to self-esteem reduction.
Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99).
- Reproductive disorders (due to follicle maturation disorder/ovule maturation disorders with consecutive anovulation (failure to ovulate) or luteal insufficiency/jelly body weakness).
