. There are many different types of menstrual disorders that vary with signs and symptoms, including pain during menstruation, heavy bleeding, or absence of menstruation. Normal variations can occur in menstrual patterns but generally menstrual disorders can also include periods that come sooner than 21 days apart, more than 3 months apart, or last more than 10 days in duration. Variations of the menstrual cycle are mainly caused by the immaturity of the hypothalamic-pituitary-ovarian (HPO) axis, and early detection and management is required in order to minimize the possibility of complications regarding future reproductive ability. Though menstrual disorders were once considered more of a nuisance problem, they are now widely recognized as having a serious impact on society in the form of days lost from work brought about by the pain and suffering experienced by women. These disorders can arise from physiologic sources (pregnancy etc.), pathologic sources (stress, excessive exercise, weight loss, endocrine or structural abnormalities etc.), or iatrogenic sources (secondary to contraceptive use etc.).

Types of menstrual disorders

Premenstrual Disorders

* Premenstrual syndrome (PMS) or premenstrual tension refers to the emotional and physical symptoms that routinely occur in the two weeks leading up to

menstruation Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hor ...

. Symptoms are usually mild, but 5-8% of women experience moderate to severe symptoms that significantly affect daily activities. Symptoms may include anxiety, irritability, mood swings, depression, headache, food cravings, increased appetite, and bloating. * Premenstrual dysphoric disorder (PMDD) is a severe mood disorder that affects cognitive and physical functions in the week leading up to menstruation. Premenstrual dysphoric disorder is diagnosed with at least one affective, or mood, symptom and at least five physical, mood, and/or behavioral symptoms.

Disorders of ovulation

Disorders of ovulation include oligoovulation and anovulation: *

Signs and symptoms of menstrual disorders

The signs and symptoms of menstrual disorders can cause significant stress. Abnormal uterine bleeding (AUB) has the potential to be one of the most urgent gynecological problems during menstruation. Dysmenorrhea is the most common.

Premenstrual Syndrome (PMS)

Symptoms may include irritability, bloating, depression, food cravings, aggressiveness, and mood swings. Fluid retention and fluctuating weight gain are also reported. Precipitating risk factors include: stress, alcohol consumption, exercise, smoking, and some medications.

Amenorrhea

Lack of a menses by the age of 16 where secondary sexual characteristics have developed or by the age of 14 where no secondary sexual characteristics have developed (primary amenorrhea), or lack of a menses for more than 3–6 months after first menstruation cycle. Although missing a period is the main sign, other symptoms can include: excess facial, hair loss, headache, changes to vision, milky discharge from the breasts, or absence of breast development.

Abnormal Uterine Bleeding

One-third of women will experience abnormal uterine bleeding in their life. Normal menstrual cycle has a frequency of 24 to 38 days, lasts 7 to 9 days, so bleeding that lasts longer could be considered abnormal. Very heavy bleeding (for example, needing to use 1 or more tampons or sanitary pads every hour) is another symptom.

Dysmenorrhea

Especially painful or persistent menstrual cramping that occurs in the absence of any underlying pelvic disease. Pain radiating to the low back or upper thighs with onset of menstruation and lasting anywhere from 12 to 72 hours. Headache, nausea, vomiting, diarrhea, and fatigue may also accompany the pain. Pain may begin gradually, with the first several years of menses, and then intensified as menstruation becomes regular. Patients who also have secondary amenorrhea report symptoms beginning after age 20 and lasting 5–7 days with progressive worsening of pain over time. Pelvic pain is also reported.
