What is the cause of nausea caused by delayed menstruation?

If female friends encounter delayed menstruation and nausea in their lives, the first thing they think of is whether there is a possibility of pregnancy. If so, they can check their body first, using pregnancy test sticks or test paper for testing. If you are not pregnant, you should go to a regular hospital for a physical examination to see if there is any endocrine disorder in your body.

First of all, after considering the possibility of pregnancy due to delayed menstruation, it is still possible that it is due to poor endocrine function. It is recommended that you should actively adjust your diet, pay attention to eating less raw, cold and irritating foods, and improve gastrointestinal discomfort.

We all know that normal women have a menstrual period every month. However, once menstruation is irregular, women will be particularly worried, and some symptoms will seriously affect women's physical health, especially irregular menstruation will even affect women's normal pregnancy, so female friends are often particularly concerned about the menstrual cycle. Many women will encounter symptoms such as not being pregnant but not having menstruation, and they don’t know what the cause is and how to regulate it. Let’s understand what is going on with not being pregnant and not having menstruation.

I am not pregnant and I don't have my period. What's going on?

Excessive weight loss and bad living habits, such as irregular diet, late bedtime and late waking up, skipping breakfast for a long time, etc. Women are under too much pressure at work and in study, which can lead to an uncoordinated lifestyle.

The main reason for delayed menstruation in women is gynecological diseases, such as cervicitis, endometritis, vaginitis, etc., which can cause menstrual disorders in women.

The menstrual cycle is generally 28 to 30 days. About 7 days earlier or later is still within the normal range, and the length of the cycle varies from person to person. But if it exceeds this time, women with normal menstruation will definitely worry. There are four situations:

1. Pregnancy

You can use the "Early Pregnancy Test Strip" to test your urine 7 days after your period is delayed. If the result is positive, you are likely to be pregnant. If the result is negative, the opposite is true. But if you are pregnant, there will be other symptoms such as nausea, breast tenderness, etc. Of course, the last resort is to go to the hospital for an ultrasound examination.

2. Side effects of medication

For example, endocrine disorders after long-term use of contraceptives can also cause delayed menstruation. Doctors also found, based on patient feedback, that a new generation of gastric motility drug, metoclopramide, also known as domperidone, may also cause this condition. Since metoclopramide does not easily cross the blood-brain barrier, it is believed that it has no inhibitory effect on central dopamine receptors. Central dopamine receptors are inhibited, resulting in a decrease in the amount of hypothalamic release factors entering the anterior pituitary. As a result, the anterior pituitary secretes less gonadotropin and corticotropin, leading to amenorrhea and delayed ovulation.

3. Caused by surgery

For example, intrauterine surgery may cause cervical adhesions, which may lead to menstrual blood stasis and thus delay menstruation.

4. Others

Such as psychological factors such as mental tension, stress, environmental changes, and some diseases that affect endocrine system. Can cause delayed menstruation.

No regular living habits. According to research, when women are exposed to cold during menstruation, the blood vessels in the pelvis will contract excessively, which can cause oligomenorrhea or even amenorrhea. Therefore, women should have a regular daily life, avoid excessive fatigue, and especially keep away from cold and damp during menstruation.

Excessive weight loss causes delayed menstruation: In real life, women who love beauty take some weight loss drugs or diet excessively in order to maintain their figure and control their weight, which may cause delayed menstruation.
