Can asthma cause coughing up blood?

If asthma patients keep coughing for a long time, they may develop symptoms of coughing up blood. For these patients, if they want to effectively solve and improve the problem, they should pay attention to correct treatment and care. Smokers should quit smoking. At the same time, they should strengthen physical exercise, improve the body's immune ability, pay attention to temperature changes, and prevent colds.

(1) Patients who smoke should first quit smoking. The incidence of chronic bronchitis in smokers is many times higher than that in non-smokers. After quitting smoking, the patient's lung function will be greatly improved. At the same time, passive smoking should also be avoided.

(2) Strengthen physical exercise to enhance the body's resistance. The amount of exercise should be determined according to your physical condition. You can take a walk, do boxing, jog, etc. every morning to breathe fresh air and promote blood circulation. Exercise in winter can improve the ability of the respiratory mucosa to adapt to cold air.

(3) Adjust the room temperature properly to prevent colds. The indoor temperature should not be too high in winter, otherwise the temperature difference with the outdoor temperature will be large, making it easy to catch a cold. In summer, you should not seek coolness and should use air conditioners at moderate temperatures. Otherwise, you may get a "heat cold" when going out, which may trigger an attack of bronchitis. During the influenza season, try to avoid going out in crowds and do not take off your clothes suddenly when you sweat a lot to prevent catching a cold. Pay attention to adding or removing clothes with the seasons. The elderly can get influenza vaccines to reduce the chance of influenza infection.

(4) Select necessary multifunctional treatment and protective measures.
