Patients with hives should try not to drink coffee because it is a stimulating diet. In addition, spicy and irritating food such as raw onion, raw garlic, strong tea, chili pepper and mustard are also not allowed to be consumed. Patients with hives should also avoid eating beef and mutton, seafood, eggs, milk, duck eggs, goat’s milk and scallops and other hairy items. If the patient has severe gastric disease and a combination of H. pylori infection, active treatment of the original disease is required. If the patient has a definite infection, such as tonsillitis or severe pharyngitis, anti-infective treatment is also required. Patients with secondary medical conditions, such as coronary heart disease, diabetes, hyperlipidemia, etc., should also be treated aggressively for medical-related conditions. These are all causes of hives that need to be avoided.
