Good morning Sheila, thank you for asking at HealthReplies.com. Menstruation is a normal medical event that occurs in every woman of her reproductive age, from adolescence, to about middle age. Regular menstruation usually occurs in 3-7 days, and recurs in 21-35 days later.
If there are irregular periods, the causes include:
Stress or anxiety
Fatigue and lack of sleep
Too much activity
Active or passive smoking
Using contraception that contains hormones
Thyroid hormone disorders
Body weight goes up and down too dramatically
Consumption of junk food, fast food and fatty foods
Sports are too extreme
A diet that is too extreme
Ovarian cyst syndrome
So what you experience can indeed be related to one another, for example if you have too much activity, and you eat less, you can lose weight, fatigue, which affects the appearance of these symptoms. This does not need to worry too much, because what you need to do is enough to improve your lifestyle, by limiting activities, adequate rest, avoiding stress and cigarette smoke, multiply the consumption of nutrient-rich foods such as vegetables, fruit and meat, maintaining ideal body weight and regular exercise according to ability. It is only when all efforts to improve lifestyle is done but menstruation is also not regular, check yourself to the obstetrician. So, hopefully answering your question.
