For women who suffer from insomnia and sweating after hysterectomy, it is generally considered to be related to the body not recovered and lack of estrogen in the body. Amino acid infusion has certain therapeutic effect on women whose body has not recovered; however, the improvement of the symptoms is not obvious for women who lack estrogen. 1. The body has not recovered: Since surgery is a great trauma for women, if women do not have sufficient rest or supplemental nutrition, it may lead to slow recovery of the body and symptoms such as insomnia, sweating, fatigue and easy fatigue, etc. Since amino acids are essential nutrients for the human body, the patient’s symptoms may improve after supplementation. 2. Lack of estrogen in the body: As the uterine artery will be blocked during hysterectomy, affecting the blood supply to the ovaries, so patients may experience insomnia, sweating, hot flashes, and other menopausal symptoms after the operation, and this is considered to be caused by the lack of estrogen, so it should be supplemented with estrogen and progesterone as prescribed by the doctor, or the use of traditional Chinese medicine to adjust the balance of the body, and the effect of supplementation of amino acids is not generally significant. For women who suffer from insomnia and sweating after hysterectomy, it is recommended that they go to a regular hospital to get a clear cause of the disease and then be actively treated under the guidance of the doctor, and not blindly use drugs.
