Bronchitis usually takes 1-2 weeks, but some patients with weak body resistance or those who do not pay attention to taboos may take longer. For patients with acute bronchitis, the disease can be cured in 1-2 weeks by taking some herbal medicines with diet regimen. For patients with chronic bronchitis, in addition to taking medication, special attention should be paid to diet and rest. If you just pay attention to the medication but not to the diet, the disease will take a little longer. First of all, patients with chronic bronchitis must avoid eating sweet, salty, spicy, cold, seafood, beef and mutton, fried, baked, all these things are not allowed. You can combine this with some dietary therapy by cooking some radish, green or white, to help dissolve phlegm and help the recovery of the disease.
