Sweating may be associated with heart disease, or with factors such as hyperthyroidism and menopause. 1. Heart disease: myocardial ischemia is severe during acute attacks of cardiac insufficiency and angina pectoris, and sympathetic nerve excitation can lead to sweat gland secretion of sweat. 2. Hyperthyroidism: thyroid hormone is high in the blood of hyperthyroid patients, who are in a state of sympathetic excitation and high metabolism, and often have high metabolism symptoms such as sweating, hyperphagia, easy to get hot, and easy to get excited. 3. Menopause: Menopausal patients have lower estrogen secretion and unstable vasodilatation symptoms, which often lead to sweating, hot flashes (a burst of fever) and other symptoms. 4. Others: In addition to the above factors, sweating may also be associated with anemia, infection, rheumatism and immunity. It is recommended that the patient go to the local hospital as soon as possible for further examination, clarification of the cause of the disease and early treatment.
