Cold and vomiting in the back may be caused by cold, acute gastritis, acute cholecystitis and other diseases. 1. Cold: when the patient is cold and chilled, it may cause the body’s resistance to decline by the invasion of viruses, causing viral colds, which tends to produce an inflammatory reaction throughout the body, with symptoms of fever and sweating, thus making the patient feel cold in the back. The virus can also affect the function of the gastrointestinal tract, vomiting and other symptoms. 2. Acute gastritis: when eating cold, spicy and stimulating foods, it is easy to damage the mucous membrane of the gastrointestinal tract causing acute gastritis, leading to symptoms of acid reflux in the stomach causing vomiting. Frequent vomiting may cause the patient’s body to become dehydrated, causing electrolyte disorders, and may also lead to symptoms of back cold. 3. Acute cholecystitis: When cholecystitis is in acute attack, due to the obstruction of bile excretion, the gastrointestinal tract digestive function decreases, there may be dyspepsia, causing symptoms of vomiting. Inflammatory factors may also stimulate the organism to develop chills and fever, which may cause the patient to develop the symptom of a cold back. Patients with cold back accompanied by vomiting should go to the hospital in time for relevant examinations and receive regular treatment under the guidance of the doctor.
