Pneumonia generally does not cause swelling of the feet. Pneumonia is mainly due to various infectious or physicochemical factors that damage our alveoli, causing inflammation in the lungs, which leads to pneumonia. The main symptoms of pneumonia include coughing, fever, difficulty breathing, chest tightness, and expectoration. Generally, swelling of the feet does not occur. The occurrence of foot swelling is mostly due to right heart failure or poor venous flow in the cavity, and the stagnation of blood flow in the lower limbs leads to this edema. If this occurs, it is important to consider whether it is due to heart failure in the elderly, or conditions such as kidney or liver diseases leading to hypoalbuminemia, and relevant tests should be conducted. This is not a complication caused by pneumonia itself, but rather a problem with some other organs of the patient.

What should a child with pneumonia eat?

Childhood pneumonia is an infectious disease that not only presents symptoms related to the respiratory system but also may include symptoms from the gastrointestinal tract, such as vomiting, diarrhea, loss of appetite, and abdominal distension. Therefore, the diet for pneumonia must be light and easy to digest. For instance, if the child is breastfed, the mother should consume a light and digestible diet. If the child is fed with cow's milk, the milk can be diluted appropriately to aid digestion. Supplementary foods can generally include thin porridge, noodles, rice paste, vegetables, and fruits, as well as a moderate amount of lean meat and eggs, but not in excess. Oily and spicy foods should not be included.

What are the symptoms of pneumonia?

Pneumonia can have many manifestations, and each person's symptoms can be different. It is highly heterogeneous, varying from mild to severe and can last for short or long durations. The main factors depend on the type of pathogen involved and the state of the body. The most common symptoms of pneumonia are coughing and producing sputum. The cough can be mild or severe and may be accompanied by sputum. The amount of sputum can vary and may be yellow, green, red, or rust-colored. Other possible symptoms include chest pain, difficulty breathing, respiratory distress, and most cases of pneumonia also involve fever. The duration and severity of the fever are somewhat related to the course of the illness. However, a small portion of patients may have atypical symptoms, especially older adults, who may not show direct respiratory symptoms but instead exhibit consciousness disturbances such as coma, confusion, fatigue, and more.

Is pneumonia serious?

Is pneumonia serious, and what will happen if it worsens or goes untreated? Severe pneumonia can lead to septic shock and can even be life-threatening. If pneumonia is not treated or not treated thoroughly, it can deteriorate into the following conditions: First, it can cause lung abscesses and empyema, and even lead to pericarditis, meningitis, and more; Second, the infection can enter the bloodstream, causing bacteremia and even septic shock; Third, the patient's continuous high fever can lead to febrile convulsions and even the possibility of coma; Fourth, extensive pneumonia can reduce the function of the alveoli, causing hypoxia and carbon dioxide retention. Hypoxia can affect the function of the nervous system, and patients with severe pneumonia may experience drowsiness, irritability, and even convulsions and coma.

Can pneumonia recur?

Can pneumonia recur? It should be decided based on an individual's constitution. If one has normal immunity and a good constitution, generally, it will not recur after recovery. If one is frail or has low immunity, there is also a certain chance of recurrence clinically. Therefore, it is important to timely adjust the constitution and enhance immunity. One should drink more water, quit smoking and alcohol, avoid exposure to smoke, dust, second-hand smoke, and irritating chemicals, and do more aerobic and endurance exercises. This can help improve the body's immune capabilities and aid in disease recovery.

How many shots are in the pneumonia vaccine?

Currently, there are two general types of vaccines for preventing pneumococcal pneumonia. One type is the 23-valent vaccine, suitable for high-risk populations over two years old. The other type includes the 7-valent or 13-valent vaccines, which are for preventing pneumococcal infections in infants under two years old. Infants under two usually follow a "three plus one" vaccination regimen, which involves three primary immunization doses with at least one month between each dose, followed by a booster shot. Additionally, adults over two years old or other high-risk groups are advised to take the 23-valent vaccine, which requires only a single dose. However, those who are frail or have poor immune responses may need a second booster dose five years after the initial vaccination.
