Irregular Periods in Teens – Causes and Treatment

Q: I have had my period now for 12 days. My periods are very irregular during which my breasts get swollen. I have terrible cramps and extremely heavy periods that last 4 days or less. The last period I had before this one was in March. Also, I passed a large clot, about a quarter size; I am somewhat concerned about it. My period is not super heavy. I go through maybe 2 regular tampons per day but it seems like it will never end. Help please.

Most of the time, irregular periods are part of the normal changes that can happen when you’re a teen. At some point as you get older, your cycle will probably settle into a recognizable pattern. 

It is common and absolutely normal to have the following symptoms during menses:

  • back cramps or stiffness
  • heavier breasts or breast soreness
  • headaches
  • acne breakouts
  • disturbed sleep patterns
  • mood swings
  • bloating
The presence of any of these symptom is normal and needs no treatment medically. Symptomatic relief can be provided in the form of a pain reliever and a muscle relaxant during those days.

Causes of Irregular Periods

Disturbed or irregular periods can have medical causes too:

  • It can be as a result of a hormone imbalance. This is common for a few years after puberty and before the menopause. This can cause your menstrual cycle to become longer or shorter. Your periods may also become lighter or heavier. 
  • Extreme weight loss or weight gain
  • Excessive exercise
  • Stress 
  • Sudden withdrawal of any contraceptive pill being taken
  • A thyroid disorder is another possible cause. The thyroid gland, found in the neck, produces hormones that maintain the body’s metabolism). Your doctor may test for a thyroid problem by taking a blood test to check the levels of thyroid hormones in your blood.
To make an exact diagnosis, I need to know more about your case:
  • When did you start having your first period, what age? 
  • Were the periods regular then?
  • Any other symptom you have beside your menstrual problem?

      Irregular periods can happen by any factor that disturbs or affects the hormonal levels of the female reproductive hormones.

      The menstrual cycle is regulated by two hormones basically, estrogen and progesterone. So anything that affects their production is liable to affect the your periods.

      For example, mental stress of any kind triggers the production of cortisol, the so called stress hormone.
      Cortisol can affect the ovary and hence the production of female hormones. So menses can get affected.

    I’m fourteen and I’ve had my period since I’ve been 12. Ever since then, my period has been very irregular, never coming on the same time and it comes twice a month. Each time for seven to eight days and my flow makes me bleed through two super tampons per thirty minutes. My doctor keeps telling me to wait it out but my mom was talking to my sister’s doctor and she said to bring me in so we can get me on the pill. I’m so confused!

      Menses do take time to stabilize in young females. There is nothing to be worried about.

      In most girls, after 6 to 8 menstrual cycles, the pattern gets stabilized and regular. However, some girls may take more time.

      Since it has been two years now, you may go for a medical evaluation. Do you have any other symptom, like lethargy, weight gain etc? Thyroid problems may also present in a similar way.

      Get your thyroid profile done to rule any endocrine cause from this gland. Read more about other causes of disturbed menses.

      Treatment with pills is not recommended, since you are too young. Pills have many side effects and are not the best way to treat unless very essential.

      You need to see a gyne for evaluation. An U/S pelvis may be done.

      Ayurvedic medicines are not prescribed here.

    23 years and have not started menstruating and I went for a pelvic U/S scan and the result say small size uterus. The ovaries are not visualized. There is no abnormal adnexal mass. The POD is empty. What should the person do?

      Why were the ovaries not visualized? What about your hormonal levels?

      Do you have some underlying medical condition, like thyroid problem etc.
