The following are the preventive measures for pink foamy sputum: Emphysema may be asymptomatic at the beginning or only feel short of breath during labor and exercise, and gradually it is difficult to perform the original work. As the disease progresses, the degree of dyspnea will worsen, to the extent that a little activity or even completely rest still feel short of breath.

To prevent colds, try to take some natural and pollution-free green organic health food. 2.Control the dietary structure: avoid excessive intake of acidic substances, which will aggravate the acidic body. Drink more food rich in plant organic active alkali, eat less meat, eat more vegetables. Chama-gu is rich in plant organic active alkali, can quickly eliminate acid toxicity in the body, so that the body’s lipid and sugar metabolism is normal, so as to control the stability of blood sugar. After the blood sugar acid-base balance, it can make the acidic deposits on the blood vessel wall fall off and excrete them out of the body with blood circulation.
