Back cold sweat, may be physiological reasons, such as shock, etc.; may also be pathological reasons, such as colds, diabetes, gastric ulcers and other causes.
1. Physiological reasons: when a person is frightened, the mood is suddenly tense, the sympathetic nerves are strongly excited, and the heartbeat is accelerated, which leads to the stimulation of the sweat glands, and at this time the secretion of sweat glands will increase, so the back sends out cold sweat.
2. Pathological causes
(1) Colds: If the body is cold and the resistance drops, it is easily infected by bacteria and viruses, thus causing colds. Patients with colds may also have the symptom of cold sweat from the back, which may be accompanied by symptoms such as cough and runny nose.
(2) Diabetes: Diabetic patients often have the manifestation of hypoglycemia, patients often show palpitations, sweating, hand tremors and other symptoms, serious cases may appear mental changes, and even life-threatening.
(3) Gastric ulcer: Increased gastric acid or reduced protective mucus, resulting in damage to the gastric mucosa, which can lead to the formation of gastric ulcers, or even gastric perforation. Typical symptoms of gastric perforation are sudden epigastric pain, which is cut-like, radiates to the shoulder and soon spreads to the whole abdomen. Patients often appear pale, cold sweat, cold limbs, thin pulse and other symptoms of shock.
The above are only some of the common causes. If physiological causes are ruled out, the patient should consult a doctor in time to clarify the specific cause and, if necessary, carry out the corresponding standardized treatment.
