Nowadays, many womens suffer from sudden weight loss caused by malnutrition, it can be by following a severe or wrong diet.

Diets with low omega-3s can cause a severe restriction of the calories amount that are needed for production of hormones which are involved in your ovulation.

Also, suffering from eating disorders like anorexia nervosa or bulimia is a warning sign that your body is not functioning correctly, and should not be taken lightly. It is better for you to visit a nutrition specialist.

2- Stress: (Sickness of the 21 Century)

Stress has been dubbed the Health Epidemic of the 21st Century by the World Health Organization, evidence continues to say that high levels of stress cause negative health outcomes through increasing a body hormone: 

  • Cortisol: high cortisol levels over a prolonged time suppress normal levels of reproductive hormones which potentially leads to abnormal ovulation.

It’s better to lower your stress level during the day by avoiding stressful activities or try to practice some deep breathing exercises etc …


If your body suffers from  obesity, with a BMI more than 30, your Body may produce an excess amount of estrogen that has a direct effect on ovulation.

Estrogen triggers the brain to release two hormones: luteinizing hormone (LH) and Follicle-stimulating hormone (FSH).

These two hormones then causes the dominant follicle to rupture and release the mature egg from the ovary, from where it enters the fallopian tube. it’s  known as ovulation.

So, women who carry excess fat cells may experience anovulation, because they react as a natural birth control due to the excess estrogen production.

If you suspect this might be an issue for you, see your healthcare provider.

4-Polycystic Ovary Syndrome (PCOS):

Currently, (PCOS) is  one of the most common hormonal endocrine disorders among women of reproductive age, recent research has estimated that between five to 10 percent of U.S. women of childbearing age have PCOS. Which makes the number to 5 million women in all.

Recent studies has approved that  such syndrome is caused by excess male hormone (androgen) levels in the blood, that leads to fluid accumulation in the ovaries  in the form of small numerous follicles, which may  affect the releasing of eggs.

How do I know if I have this syndrome ?

Firstly you must go to your doctor, he will start with a discussion about your medical history. He’s gonna ask you about your menstrual periods and weight changes. because there’s no special  test to diagnose it.

Also checking insulin resistance and acne may give a huge idea about this.

5-Thyroid dysfunction:

Suffering from  hypothyroidism and hyperthyroidism , can disturb your menstrual cycle or cause it to  stop for several months or longer, this  condition is called amenorrhea.

People with such diseases have an increase in the Thyrotropin-releasing hormone (TRH) which directly induces an elevation in prolactin levels.

This hormone leads to thinning of the uterine lining and changes the control of ovaries by the  pituitary gland; both can result in periods distribution.

6-Changing your sleeping schedule:

Any changes in the sleeping schedule by traveling or night shifting can affect your period. Recent studies proved that lack of sleep have a large effect on your period. It is by the elevation of cortisol in your blood.

7-Using Contraceptives:

 Hormonal contraceptives contain estrogen which cause your body to slow the secretion of your natural cyclical hormones.

Using such types of pills can lead to disturbed menstrual cycle. So  it’s better to seek a doctor before using it.


The menstrual cycle is a very important indicator of a woman’s overall health. That’s why any changes in your life can have a positive or negative impact on it.

So the best choice  to stay in good health is to contact your health provider regularly.
