The doctor reminds: When there are nodules in the lungs, the body generally has 3 manifestations, please pay more attention

The lung is a very important respiratory organ in the human body. Compared with other organs in the body, it is the only organ exposed to the external environment. The external vehicle exhaust, smoke pollution, dust and dust can directly enter the lungs without obstruction. .

Fortunately, the lungs have a certain cleaning ability, and can expel these toxic and harmful substances from the body through coughing, spitting, etc. However, for some children and the elderly with weak immunity, the lungs are very vulnerable to the violation of bacteria and viruses, so more attention should be paid to protecting the lung function in peacetime.

What is a pulmonary nodule?

With the popularization of CT examination technology, many friends choose to use CT instead of traditional X-rays during physical examination, so many small lung nodules that are still in the "latent period" appear their original shape. The detection rate of small pulmonary nodules is increasing year by year, and patients who are found to have pulmonary nodules may be in panic

So what exactly are pulmonary nodules?

From the imaging findings, pulmonary nodules are mostly localized, round-like shadows with increased density. The common one is a single nodule, and four or five nodules in both lungs have been seen clinically, and the borders are generally clear. Pulmonary nodules are mostly lesions less than 3 cm in diameter, and those larger than 3 cm are generally referred to as masses.

1. Impaired lung function

Because lung nodules compress surrounding tissues and nerves, patients experience mild pain due to impaired lung function, and breathing is also affected, manifested as coughing, expectoration, or chest tightness.

The onset of these symptoms is relatively short-lived, but they tend to recur. In general, the frequency of attacks is higher when the patient is exposed to bad air or has excessive mood swings.

2. Decreased appetite

If a person develops pulmonary nodule disease, the appetite will be greatly affected due to physical fatigue and reduced physical activity, such as not liking greasy food, reducing food intake or skipping meals for a long time.

If this condition persists for a long time, the patient will not only be thin, lose a little hair, but also have conditions such as immune deficiency.

3. Co-infection

If a patient develops pulmonary nodule disease and is not treated in time, it may develop co-infectious diseases, such as emphysema or bronchiectasis. At the same time, lung nodules can affect other organs.

So there are some changes in the body, such as erythema nodosum, which usually appear on the face, neck or shoulders, affecting the appearance of the skin.
