Oligomenorrhea: Or something else? Differential Diagnosis

Congenital malformations, deformities, and chromosomal abnormalities (Q00-Q99).

Laurence-Moon-Biedl-Bardet syndrome (LMBBS) – rare genetic disorder with autosomal recessive inheritance; differentiated by clinical symptoms into:
- Laurence-Moon syndrome (without polydactyly, i.e., without the appearance of supernumerary fingers or toes, and obesity, but with paraplegia (paraplegia) and muscle hypotonia/reduced muscle tone) and
- Bardet-Biedl syndrome (with polydactyly, obesity and peculiarities of the kidneys).

Endocrine, nutritional and metabolic diseases (E00-E90).

Hyperandrogenemia (elevation of male sex hormones in the blood).
Hyperprolactinemia (increase in prolactin levels in the blood).
Hypothyroidism (hypothyroidism) or latent (subclinical/mild) hypothyroidism.
Ovarian hypoplasia – underdevelopment of the ovaries due to various diseases such as Turner syndrome (gonadal dysgenesis).
Polycystic ovary syndrome (PCO syndrome) – cyst formation in the ovary, which leads to impaired hormonal function.
Sheehan syndrome – postpartum (after childbirth) anterior pituitary insufficiency (HVL insufficiency; insufficient hormone production by the anterior lobe of the pituitary gland (pituitary gland)).
Premature ovarian failure – ovarian function depletion with progressive follicular atresia (failure to produce follicles).

Neoplasms – tumor diseases (C00-D48).

Psyche – nervous system (F00-F99; G00-G99)
