Xiao Wu is a slightly fat girl. She is almost 30 years old and has yet to get married. She talked about a few boyfriends before without success. She thinks that she is too fat. Determined to lose weight, not only did I get a fitness card, but I also bought private lessons. I spent three hours in the gym every day, and I often ran outdoors.

The effect is obvious. In more than two months, people have lost a lot of weight, but troubles have also come. Xiao Wu found that her regular menstruation did not come. She suspected that it was caused by fitness, is that so?

After starting to exercise, many people pay extra attention to their posture, diet and training. In the process of losing fat, if you consume too much calories (low calorie intake, high calorie consumption) or stay in this state for a long time, it may cause the body to undergo metabolic regulation, and women may have irregular menstruation problems. Even the case of menstrual cessation (not coming for more than 3-6 months).

This phenomenon is called secondary amenorrhea, or secondary amenorrhea, which refers to the situation where menstruation has occurred, but now it is more than three menstrual cycles or more than six months without menstruation. There are many conditions that can cause this and may include: pregnancy, hyperprolactinemia, endocrine dysfunction, ovarian dysfunction, stress, being under or overweight, eating disorders, and more.

What are the possible causes of menstrual irregularities after exercising?

For menstrual disorders after exercise, we must first rule out other problems, such as genes, abnormal physiological structure, abnormal ovarian function, etc., and then find the specific reasons. Then, the cause of menstrual disorders may be classified as functional hypothalamic amenorrhea. (FHA).

Functional hypothalamic amenorrhea is mainly divided into three types:

1. Related to mental stress

2. Associated with weight loss

3. Related to sports

This is because of stress, weight, exercise and other reasons, the abnormal release of hormones in the human hypothalamus, resulting in gonadotropins secreted by the hypothalamus and estrogen produced in the ovaries are affected. Amenorrhea occurs when the ovaries do not function properly in the absence of estrogen.

In addition to this situation, some women may stop menstruation as soon as they start exercising. What is the reason for this?

Why do some girls have no menstrual period after starting to exercise?

1. Metabolic regulation

After starting to exercise, especially women will pay special attention to their posture, diet and training status. In the process of losing fat, if the gap between calorie intake and consumption is too large (low calorie intake, high calorie consumption), or if you are in a state of high consumption for a long time, for women who are relatively weak, it is easy to cause the body to appear. Metabolic regulation.

To put it simply, when a woman’s body finds a chronic energy deficit, the body will reduce energy expenditure in all aspects to ensure that it can survive. Fertility-related functions may be suspended because of this. At this time, there may not only be amenorrhea, but also the characteristics of decreased sexual desire.

The training intensity

High-intensity or high-volume training can cause hormonal fluctuations in the body (GnRH, cortisol, testosterone, etc.). If a person performs high-intensity or high-volume training and is in a state of substantial calorie reduction for a long time, it may occur due to excessive fluctuations (high-intensity training) + too little recovery and adjustment ability (metabolic adjustment) in the brain’s hypothalamus. Abnormal hormone release, and the phenomenon of amenorrhea occurs.

3. Abnormal diet adjustment

Excessive dieting (excessive calorie consumption or long-term fat loss) is one possible cause of menopause. In addition to the calorie investigation, the intake of nutrients also needs attention.

Everyone’s physiological response to different eating habits (low-fat, low-carb, intermittent fasting, etc.) is different, but drastic changes in eating habits often affect hormone levels in the body. Try to avoid drastic changes in eating habits, and gradual changes will be more conducive to the body to regulate homeostasis.

In addition, the intake of micronutrients is equally important. Diet is not only to take into account the three major nutrients (carbohydrate, fat, protein), various micronutrients (vitamins and minerals) are also necessary for the maintenance of body functions. Chicken breast + cauliflower + rice may be the first choice of food for many fitness people, but if you eat this kind of food every day, you will not be able to absorb many other necessary trace elements, resulting in nutritional imbalance.

Fourth, weight loss, body fat loss

Being underweight or having low body fat may affect hormone secretion. Significant weight loss and body fat loss are usually the result of excessive or prolonged caloric consumption. If women experience menopause in the process of weight loss and fat loss, it means that women may need to reconsider their fat loss rate, or temporarily increase their calorie intake.

According to the above situation, we can actually find that Xiao Wu’s menstrual disorders after exercising are mainly caused by life changes, substantial weight loss, and increased exercise intensity and other comprehensive problems, so she needs to lose weight for herself It is possible to return to normal by adjusting in a way and maintaining comprehensive nutrition.

So, does it mean that low body fat will definitely have menstrual disorders, that is, thin women will definitely have menstrual disorders?

Does low body fat prevent menstrual disorders? Do only thin people have menstrual irregularities?

Low body fat does not necessarily mean menstrual disorders, and menstrual disorders are not only a problem for thin girls.

Some girls have low body fat, but they consume enough calories to support their activities and body functions. Low body fat does not necessarily mean that the body is in a state of metabolic adjustment.

How much body fat is lower than what may cause menstrual disorders? This is a common question many people have. But its solid fat and menstruation have not been proven to have any direct link. In addition to body fat, genes, large calorie consumption, eating habits, lifestyle habits, etc. may be related to menstrual disorders.

Maybe women’s body fat is not low, but they have menstrual disorders after starting to exercise and diet. Don’t take it seriously! Menstrual irregularities are often abnormal signals from the body that remind women that they need to pay more attention to their health.

For the average person, please suspend the fat loss plan at this time and seek the help of a doctor or professional.
