Menstrual Issues and Amenorrhea problem.

 

Menstruation, commonly known as a period, is the natural, monthly shedding of the uterus lining. It is a key part of the menstrual cycle, signaling that the body is preparing for a potential pregnancy. Most individuals with a uterus experience this biological process, which usually begins between 9 to 15 years old and continues until menopause. 

A typical menstrual cycle spans from the first day of bleeding to the first day of the next period is about 28 days plus or minus. 

Clinically speaking, we see a lot of young girls experiencing menstrual pain during their teenage.  Also they have delayed menses, early menses, or amenorrhea problems.  These girls usually like to take cold drinks, some even like to bite ice cubes.

Delayed or irregular menstruation in young girls can happen for many reasons, and some are completely normal while others may need medical attention.

A girl’s periods are often irregular for the first 2–3 years after they begin because hormones are still maturing. But if periods are very delayed, absent, or suddenly stop, common causes include:

• Normal puberty variation — some girls simply start later than others.
• Low body weight or excessive exercise — intense sports, dieting, eating disorders.
• Weight gain or obesity — can affect hormone balance.
• Stress or emotional changes — exams, anxiety, family stress, poor sleep.
• Thyroid problems — both overactive and underactive thyroid can disrupt periods.
• Polycystic ovary syndrome (PCOS) — a hormone condition that may also cause acne or excess hair growth.
• Nutritional deficiencies — especially iron deficiency or poor nutrition.
• Chronic illness or medications — some medical conditions affect hormone cycles.

Doctors usually become more concerned if:

• periods have not started by age 15, or
• there is more than 3 months without a period after periods had already started regularly, or
• there are symptoms like severe pain, excessive hair growth, major weight changes, or milky breast discharge.

A pediatrician, family doctor, or gynecologist may check:

• growth and puberty development,
• diet and exercise,
• stress levels,
• blood tests for hormones or thyroid,
• sometimes an ultrasound.

• signs of PCOS,

A “normal” teen cycle usually means:

• First period age: commonly between 12–15 years
• Cycle length: often 21–45 days in the first few years
• Bleeding duration: about 2–7 days,
• Flow: light to moderate,
• Irregularity: skipped months or uneven timing can happen during the first 2–3 years

After a few years, cycles usually become more regular:

• around 21–35 days per cycles

Doctors may want evaluation if:

• no periods by age 15
• periods started but then stop for more than 3 months
• very heavy bleeding (soaking pads hourly)
• severe pain preventing school/activities
• cycles remain very irregular years after starting

Signs of Polycystic Ovary Syndrome (PCOS)

PCOS is a hormone imbalance that can affect teenagers and young women. Symptoms vary, and not everyone has all of them.

Common signs include:

• Irregular or missed periods
  • periods far apart
  • very light or very heavy periods
  • skipped months
• Acne
  • especially persistent or severe acne on the face, chest, or back
• Excess hair growth
  • thicker/darker hair on the face, chest, abdomen, or chin
• Weight gain or difficulty losing weight
• Oily skin
• Thinning scalp hair
  • hair shedding similar to male-pattern hair loss
• Darkened skin patches
  • especially around the neck, armpits, or groin (can suggest insulin resistance)

Some girls with PCOS also have:

• mood changes
• fatigue
• trouble with blood sugar control

Doctors diagnose PCOS using:

• menstrual history
• physical examination
• blood hormone tests
• sometimes ultrasound

In teenagers, diagnosis can be tricky because irregular periods and acne are also common during normal puberty, so doctors look for a consistent pattern over time.

Treatment may include:

• healthy nutrition and exercise
• weight management if needed
• acne or hair-growth treatments

If you want, I can also explain:

• how doctors test for PCOS,
• the difference between normal teen irregular periods and PCOS,
• or foods/lifestyle changes that may help regulate periods.

There are a lot of women having uterus issues such as endometriosis or polycystic ovary syndrome (多囊卵巢综合征)
