Most patients with tuberculosis do not have a low fever in the morning, but have a persistent low fever in the afternoon, usually starting from 1-2 o’clock at midnight, and then gradually returning to normal until the afternoon, when they have a low fever in the afternoon, accompanied by sweating, hot flashes, and sweating profusely after waking up. It is accompanied by coughing, coughing up blood, coughing up sputum, and long-term wasting and weakness, and in the worst case, loss of appetite and mental atrophy. Tuberculosis is a chronic wasting disease, so the general hypothermic state of body temperature is such a pattern that most mornings do not have a low fever.
