The treatment means taken after weight loss without menstruation need to refer to the specific weight loss method, because the weight loss method is different, the treatment of not coming to menstruation is also slightly different. If the period does not come for a long time, or does not recover after stopping weight loss, it is recommended to go to the hospital for a comprehensive examination to clarify the cause and deal with it symptomatically.1. Amenorrhea due to dieting: It is recommended to resume a normal diet as soon as possible. Because dieting can lead to a rapid decrease in body fat content, when the energy intake cannot meet the metabolic demand, the normal ovulation function of the ovaries will be affected. So you should resume your normal diet to ensure a normal supply of nutrition and energy, eat more protein-rich and low-fat foods, such as chicken and fish, and eat more vegetables and fruits, and some women’s periods can recover on their own; 2. Amenorrhea due to exercise and weight loss: it is recommended to temporarily stop high-intensity exercise. When infrequent exercisers suddenly exercise vigorously, the body activates the sympathetic nervous system under stress, which can cause amenorrhea. When these exercises are stopped, the absence of menstruation can be relieved; 3. Amenorrhea due to medication for weight loss: If you do not get your period due to medication, you should stop using the medication. In general, there is no absolutely safe and effective weight loss drugs, most of which can lead to endocrine disruption after taking, which in turn can lead to amenorrhea, which can be relieved in some people after discontinuing the drugs. If menstruation does not resume after 1-2 months of taking the above actions, it is recommended to go to the hospital for a comprehensive examination to check whether there are organic lesions in the uterus through ultrasound and to clarify the endocrine function through hormone six examination, and to take or inject estrogen and progesterone as prescribed by the doctor if necessary, which can achieve the purpose of treatment.
