Reasons for delayed menstruation in girls

People's normal menstrual cycle should be about 28-30 days. Seven days earlier and seven days later are both normal phenomena. However, if menstruation is often delayed, you should consider whether it is caused by the effects of drugs, surgical reactions or other factors. However, if menstruation is suddenly delayed, the possibility of pregnancy cannot be ruled out, and you need to go to the hospital for examination as soon as possible.

1. Pregnant

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 very likely pregnant. If the result is negative, then vice versa. 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. The amplitude of drug effect

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 gastrokinetic 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. Surgery

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

4. other

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

Expert tip: If menstruation is delayed only 1-2 times occasionally and there are no other accompanying symptoms, it does not fall into the category of menstrual disorders. When the interval between menstrual cycles is more than 35 days, it is called oligomenorrhea, and when menstruation stops for more than 3 menstrual cycles, it is called amenorrhea. The absence of ovulation after menopause can also lead to problems such as osteoporosis and endometrial hyperplasia, which must be taken seriously. You should go to the hospital immediately for a comprehensive examination.

Delayed menstruation

A delay of more than one week in the menstrual cycle is called late menstruation. A person whose menstrual period is normal but whose menstrual flow is reduced is called oligomenorrhea. Late menstruation and scanty menstruation often occur together. This disease can be divided into deficiency and excess. If you see symptoms such as sore waist and cold limbs, tinnitus and dizziness, abdominal pain with a feeling of emptiness and sagging, and likes to be pressed and warmed, it is generally a deficiency and cold disease caused by kidney and blood deficiency. If you see lower abdominal distension and pain that refuses to be pressed, dark menstrual blood with clots, pain and distension under the clots reduced, and depression, then these are signs of blood stasis and qi stagnation. The self-treatment of this disease adopts two methods: tonifying and clearing.

Self-treatment precautions

(1) If menstruation is delayed or the menstrual flow is reduced but there is no obvious discomfort, there is no need to rush to self-treat. We can observe for 2-3 cycles before making a conclusion. (2) Food and drinks should be nutritious and well-balanced. Eat less cold foods, such as watermelon, cucumber, clams, snails, mussels, lily, potatoes, mung beans, etc. Avoid acidic foods or foods that have astringent effects, such as black plums, ginkgo nuts, pomegranates, etc. (3) Be cheerful. Depression can cause obstruction of qi, poor blood flow and difficulty in menstruation.

(4) Late menstruation is associated with low menstrual volume and physical weakness. Patients should participate in more recreational and sports activities to improve their body's resistance. (5) Reduce sexual intercourse.
