Menstrual Disorders Indian Medical PG Practice Questions and MCQs

Question 211: Primary amenorrhea is defined as:

A. Imperforate hymen exists
B. None of the above
C. Menstruation does not occur even after 15 years of age (Correct Answer)
D. Menstruation does not occur even after 18 years

Explanation: ***Menstruation does not occur even after 15 years of age*** - Primary amenorrhea is defined as the **absence of menstruation by age 15** in individuals with normal secondary sexual characteristics. - This definition is crucial for determining when to initiate investigation for underlying causes. *Imperforate hymen exists* - While an imperforate hymen can cause **cryptomenorrhea** (menstruation occurring but not flowing out), it is a specific cause of primary amenorrhea, not the definition itself. - An imperforate hymen is identified by a **bulging, bluish membrane** at the vaginal introitus. *None of the above* - This option is incorrect because the first option accurately defines primary amenorrhea. - The definition of primary amenorrhea is clinically well-established and widely accepted. *Menstruation does not occur even after 18 years* - This age cut-off is **too late** for the definition of primary amenorrhea, as investigations should ideally begin earlier. - Delaying evaluation until age 18 could potentially delay the diagnosis and treatment of underlying conditions affecting fertility and overall health.

Question 212: Which of the following statements is true regarding menorrhagia?

A. Bleeding volume greater than 80 ml per cycle
B. Heavy and irregularly timed episodes of bleeding
C. Heavy and regularly timed episodes of bleeding (Correct Answer)
D. Menstrual bleeding lasting more than 7 days

Explanation: ***Heavy and regularly timed episodes of bleeding*** - **Menorrhagia** is defined as **excessive menstrual blood loss** occurring at **regular intervals** (cyclical pattern). - This is the classic definition distinguishing it from other abnormal uterine bleeding patterns. - The key features are: **heavy flow** + **regular timing** (maintains normal cycle length). *Heavy and irregularly timed episodes of bleeding* - This describes **irregular heavy bleeding**, which would fall under abnormal uterine bleeding with irregular timing. - The **irregular timing** is the key differentiator that excludes this from being simple menorrhagia. *Bleeding volume greater than 80 ml per cycle* - While **>80 ml blood loss** is the objective measurement for menorrhagia, this alone doesn't capture the complete definition. - Menorrhagia specifically requires this heavy bleeding to occur at **regular intervals**. - In clinical practice, subjective assessment (soaking through pads/tampons, clots, impact on quality of life) is often more practical than measuring volume. *Menstrual bleeding lasting more than 7 days* - Duration **>7 days** describes **prolonged menstrual bleeding**. - This can occur with menorrhagia but is not the defining feature. - A patient can have menorrhagia with normal duration (3-7 days) if the volume is excessive during that period. - The definition of menorrhagia focuses on **amount** (heavy), not duration (prolonged).

Question 213: Dysfunctional uterine bleeding (DUB) is best treated by:

A. Curettage of uterus
B. Progestogen (Correct Answer)
C. Estrogen
D. Clomiphene

Explanation: ***Progestogen*** - **Progestogen** therapy helps stabilize the **endometrium**, reducing excessive or irregular bleeding in DUB by counteracting unopposed estrogen. - It induces a more organized shedding of the uterine lining, which can regularize the menstrual cycle. *Curettage of uterus* - While **curettage** can provide temporary relief by removing the endometrial lining, it is primarily a diagnostic procedure to rule out pathology rather than a primary long-term treatment for DUB. - It does not address the underlying hormonal imbalance that causes DUB, leading to a high recurrence rate of symptoms. *Estrogen* - **Estrogen** therapy alone is generally not used to treat DUB because unopposed estrogen is often the cause of DUB, leading to **endometrial overgrowth** and irregular shedding. - Administering estrogen without a progestin could exacerbate the condition and increase endometrial proliferation. *Clomiphene* - **Clomiphene** is an anti-estrogen medication primarily used to induce **ovulation** in women with infertility. - It is not indicated for the management of dysfunctional uterine bleeding or for regulating menstrual cycles directly.

Question 214: Menorrhagia is defined as:

A. Menses occurring in less than 28 days
B. Intermenstrual bleeding
C. Increased loss of blood than normal during menstruation (Correct Answer)
D. Menses occurring more than 45 days apart

Explanation: ***Increased loss of blood than normal during menstruation*** - **Menorrhagia** is specifically defined as **heavy or prolonged menstrual bleeding** that interferes with a woman's physical, emotional, social, and material quality of life. - This typically means a blood loss of more than 80 mL per cycle or menses lasting longer than 7 days, though a subjective assessment of excessive bleeding by the patient is also key. *Intermenstrual bleeding* - **Intermenstrual bleeding**, also known as metrorrhagia, refers to **bleeding that occurs between menstrual periods**. - It is distinct from menorrhagia, which concerns the characteristics of the menstrual period itself. *Menses occurring in less than 28 days* - This describes **polymenorrhea**, which is characterized by **frequent menstrual periods** (e.g., cycles shorter than 21 days). - While it can be associated with increased bleeding frequency, it does not directly define the volume or duration of blood loss like menorrhagia does. *Menses occurring more than 45 days apart* - This describes **oligomenorrhea**, which refers to **infrequent menstrual periods** (e.g., cycles longer than 35 days but less than 6 months). - It is the opposite of polymenorrhea and is not related to the excessive blood loss that defines menorrhagia.

Question 215: 22-year-old female comes to your outpatient department complaining of frequent periods, which occur every 18 days. What is this condition called?

A. Polymenorrhea (Correct Answer)
B. Metrorrhagia
C. Hypermenorrhea
D. Menorrhagia

Explanation: ***Polymenorrhea*** - This term describes **menstrual bleeding** that occurs **more frequently than normal**—specifically, an interval of **less than 21 days** between periods. - The patient's 18-day cycle falls within this definition, indicating abnormally frequent menstruation. *Menorrhagia* - **Menorrhagia** refers to **heavy or prolonged menstrual bleeding**, where the duration is typically more than 7 days or blood loss exceeds 80 mL. - It does not specifically describe the frequency of the periods. *Metrorrhagia* - **Metrorrhagia** is characterized by **irregular, acyclic bleeding** between menstrual periods, or bleeding that is not associated with the expected menstrual cycle. - This patient's periods are regular in their frequency, although too frequent, rather than irregular or intermenstrual. *Hypermenorrhea* - This term is often used interchangeably with **menorrhagia**, referring to **excessively heavy menstrual bleeding**. - It does not address the issue of the short interval between menstrual cycles.

Question 216: What is the IUCD of choice in women with menorrhagia?

A. Progesterone containing IUCD (Correct Answer)
B. Copper-T 200
C. Copper-T 380A
D. Lippe's loop

Explanation: ***Progesterone containing IUCD*** - **Progesterone-releasing IUCDs** (e.g., **Mirena**) are known to significantly reduce menstrual blood loss by causing **endometrial atrophy**. - This type of IUCD can effectively treat **menorrhagia** (heavy menstrual bleeding) and can even be used in some cases of **adenomyosis**. *Copper-T 200* - **Copper-containing IUCDs** generally **increase menstrual blood loss** and cramping, making them unsuitable for women with menorrhagia. - The **copper** evokes a local inflammatory reaction in the uterus, which can exacerbate heavy bleeding. *Copper-T 380A* - Similar to other **copper IUCDs**, the **Copper-T 380A** works by causing a local inflammatory reaction and releasing copper ions, which can lead to **increased menstrual bleeding**. - It would therefore worsen rather than improve menorrhagia. *Lippe's loop* - **Lippe's loop** is an older, non-medicated plastic IUCD that is no longer widely used and is associated with **increased menstrual bleeding** and cramping. - Its mechanism of action does not involve hormone release, and it does not offer any benefit for reducing menorrhagia.

Question 217: What is the average menstrual flow during normal menses?

A. 80ml
B. 15ml
C. 30ml (Correct Answer)
D. 50ml

Explanation: ***30ml*** - The average menstrual blood loss during a normal period is approximately **30 mL**. - While there is a range, 30 mL is often cited as the mean for defining **normal menses**. *50ml* - Although it falls within the broader definition of normal, 50ml is slightly higher than the statistically observed **average menstrual flow**. - Blood loss exceeding **80 mL** is generally considered **menorrhagia**. *15ml* - A menstrual flow of **15 mL** is on the lower end of the normal range and could sometimes be indicative of **hypomenorrhea**. - While not necessarily abnormal, it is less common as an average compared to 30 mL. *80ml* - A menstrual flow of **80 mL** is consistently considered **menorrhagia** or heavy menstrual bleeding. - This level of blood loss can lead to **anemia** and often requires investigation and treatment.

Question 218: At what age is menstruation considered precocious in females?

A. After 12 years of age
B. At 12 years of age
C. Before 10 years of age (Correct Answer)
D. At 11 years of age

Explanation: ***Before 10 years of age*** - Menstruation occurring **before the age of 10** is generally considered **precocious puberty**, warranting investigation. - While definitions can vary slightly, a threshold of **before 10 years** is a common diagnostic criterion for precocious menarche. *After 12 years of age* - Menarche **after 12 years** is within the normal range of pubertal development, with the average age being around 12.4 years in Western populations. - This age is considered **normal** or even slightly later than average, not precocious. *At 12 years of age* - **12 years of age** is well within the normal range for the onset of menstruation. - This age represents the **average or expected time** for menarche to occur. *At 11 years of age* - Menarche at **11 years of age** is considered to be within the normal, albeit earlier, end of the physiological spectrum. - This age does **not meet the criteria** for being precocious.

Question 219: Which of the following conditions can contribute to congestive dysmenorrhea?

A. Uterine fibroids causing pelvic congestion
B. Pelvic inflammatory disease leading to inflammation
C. Intrauterine device (IUD) usage causing pelvic inflammation
D. All of the options contribute to pelvic congestion (Correct Answer)

Explanation: ***All of the options contribute to dysmenorrhea*** - **Congestive dysmenorrhea** is an older term referring to secondary dysmenorrhea associated with pelvic pathology and vascular congestion. All mentioned conditions can contribute to painful menstruation through various mechanisms. - These conditions represent causes of **secondary dysmenorrhea** (dysmenorrhea with underlying pelvic pathology). *Uterine fibroids causing dysmenorrhea* - **Uterine fibroids** (leiomyomas) cause dysmenorrhea through multiple mechanisms: increased prostaglandin production, uterine distension, and compromised blood flow. - Submucosal fibroids are particularly associated with **menorrhagia and dysmenorrhea** due to increased endometrial surface area and altered uterine contractility. - Large fibroids can cause pelvic heaviness and pressure symptoms. *Pelvic inflammatory disease causing dysmenorrhea* - **Pelvic inflammatory disease (PID)** causes chronic pelvic pain and dysmenorrhea through inflammation, adhesion formation, and tubo-ovarian pathology. - The resulting **chronic inflammation** and scarring can lead to persistent pelvic pain that worsens during menstruation. - PID is a common cause of secondary dysmenorrhea in reproductive-age women. *Intrauterine device (IUD) causing dysmenorrhea* - **Copper IUDs** are particularly associated with increased dysmenorrhea and menorrhagia due to local inflammatory response and increased prostaglandin production. - The foreign body reaction causes increased uterine contractility and cramping, especially in the first few months after insertion. - Levonorgestrel IUDs typically reduce dysmenorrhea rather than cause it.

Question 220: A 32-year-old woman presents with irregular, heavy menstrual bleeding. After thorough evaluation including pelvic ultrasound, hormonal assays, coagulation profile, and endometrial sampling, no structural abnormalities, systemic disorders, or medication-related causes are identified. This clinical scenario is best described as:

A. Presence of systemic causes
B. Presence of iatrogenic causes
C. No identifiable causes present (Correct Answer)
D. Presence of identifiable organic causes

Explanation: ***No identifiable causes present*** - As per its definition, **dysfunctional uterine bleeding (DUB)** is diagnosed when no structural, systemic, or iatrogenic etiology for abnormal uterine bleeding can be found. - The diagnosis of DUB is essentially a **diagnosis of exclusion**, meaning it is made after ruling out other potential causes of bleeding. *Presence of systemic causes* - If systemic causes, such as **coagulation disorders** or **thyroid dysfunction**, are identified, the bleeding is attributed to these conditions, and it is not considered DUB. - DUB specifically implies that systemic factors have been investigated and found to be absent or not the primary cause of the bleeding. *Presence of iatrogenic causes* - **Iatrogenic causes** refer to abnormal bleeding induced by medical interventions, such as specific medications (e.g., anticoagulants, hormonal contraceptives) or medical devices (e.g., IUDs). - If such causes are identified, the bleeding is categorized accordingly, and the diagnosis of DUB is excluded. *Presence of identifiable organic causes* - **Organic causes** include structural abnormalities of the uterus or reproductive tract, such as **fibroids**, **polyps**, **adenomyosis**, or **malignancy**. - The presence of any of these identifiable pathology rules out DUB, as DUB is by definition non-organic.
