Weakness and sweating may be due to fever caused by upper respiratory tract infections and may be accompanied by cicatricial inflammation of the upper respiratory tract such as runny nose, sore throat, cough and sputum. Hypoglycemia can also be associated with sweating, panic attacks, and a feeling of hunger. Heart disease can also cause weakness, chest tightness, chest pain, and sweating, such as angina pectoris, heart attack, or severe arrhythmias, such as SC syndrome attacks. Weakness and sweating can also be an idiosyncratic infection, such as tuberculosis, and can result in false sweating, night sweats, hypothermia, afternoon hot flashes, and loss of appetite. It is recommended to visit the hospital for consultation and further detailed examination to clarify the cause of general weakness and night sweats. If it is a cold, give symptomatic treatment, drink more water and strengthen physical exercise to enhance physical fitness. If it is a heart disease, it is recommended to consult a specialist for heart disease for examination and treatment. If it is hypoglycemia, clarify the cause of hypoglycemia and give sugar supplements.
