Is it possible to get pneumonia more than once? If so, is it worse the second time (i have lung scars) or better (immune system memory)?

Is it possible to get pneumonia more than once? If so, is it worse the second time (i have lung scars) or better (immune system memory)?

Yes, it is: Pneumonia isn't a specific disease so much as fluid collecting in the air spaces of the lungs. This can be caused by a wide variety of pathogens, some of which we become immune to (some viruses) but many of which we do not (bacteria, mycoplasma, etc). So you can have pneumonia multiple times. This doesn't mean that future cases will be better or worse, although bad cases can damage the lungs.

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

What is the diagnosis and treatment for scarring on the lungs due to repeated pneumonia?

What is the diagnosis and treatment for scarring on the lungs due to repeated pneumonia?

Depends on cause: Recurrent pneumonia should be investigated and cause of the scarring determined to ensure that there is no ongoing inflammation in the involved segment of the lung. Treatment depends on underlying cause that is identified. If there is persistent infection in the lungs, it can lead to development of bronchiectasis over time. Please consult a lung specialist for detailed assessment.

Do you have to treat walking pneumonia? If recovered without treatment, does it leave permanent scarring in the lungs?

Do you have to treat walking pneumonia? If recovered without treatment, does it leave permanent scarring in the lungs?

In a way: In a way, you need to treat of course, as if it was viral (your probable case since you recovered without antibiotics) you would rest and push fluids and treat it supportively. If bacterial, you would need antibiotics. Usually, the body will heal itself, but on a rare occasion, you may leave some scarring from an old infection.

Father has multiple small lung nodules. Does not smoke. Had pneumonia several times and scarring from it on lungs 25 yrs ago. Is 70. Risk of cancer?

Father has multiple small lung nodules. Does not smoke. Had pneumonia several times and scarring from it on lungs 25 yrs ago. Is 70. Risk of cancer?

Possible: Histoplasmosis and granulomas more common in midwest. Comparison with old x-rays or ct is very helpful. New multiple lesions, and growth of lesions inclines to cancer.

I recently had a ct scan with contrast. It said I had some linear scarring in lower left lung. Everything else looked ok. I had a small granuloma on a previous scan same area. I had pneumonia in that area a year ago. I have great oxygen. That was all that

That was like you..: ..said, scarring due to pneumonia in the past. If you don't have any symptoms of fever, cough, sputum, shortness of breath, sweating or weakness, then you most likely don't have pneumonia. And a granuloma would not be anything to lose sleep over. Size and all. I would continue to monitor the situation from a distance.

I was treated for sob, after tests they saw scarring on my lungs. But I never had phenumonia, serious injury or trauma. What causes the lung scaring?

I was treated for sob, after tests they saw scarring on my lungs. But I never had phenumonia, serious injury or trauma. What causes the lung scaring?

Many possibilities: Smoking, second hand smoke (even if you never smoked), smog, air pollution, dust, fungal infections (even though you've never had pneumonia), allergic lung diseases, auto-immune lung diseases, sarcoidosis, healed TB - just to name a few. If you're still sob, you should see a pulmonary specialist. Have you had a ct scan?

Chest x Ray shows subtle scarring in left lung base after pnemounia and pleurisy. Is this bad and can it become a problem?

Chest x Ray shows subtle scarring in left lung base after pnemounia and pleurisy. Is this bad and can it become a problem?

Mgt: A virtual consult can be booked online, so that the imaging may be viewed. From your description, this type of residual scarring should not result in a decrease in lung function.

Cold, ear infection, alternative dry cough and wet cough for a month. Chest Xray showed clear lungs, chronic appearing lung scarring but no Pnuemonia. Smoker. Urgent care doctor suggested to see Pulmonary specialist. What does this mean? Is scar a problem?

Cold, ear infection, alternative dry cough and wet cough for a month. Chest Xray showed clear lungs, chronic appearing lung scarring but no Pnuemonia. Smoker. Urgent care doctor suggested to see Pulmonary specialist. What does this mean? Is scar a problem?

Nothing specific: The x-ray is really just a good screening tool and sometimes picks up old issues with little if any importance but if never seen before lead to more testing to make sure no treatment is needed. Smokers can have "dirty lungs" as can asthmatics. The term "scar" is a gestimate. It might be an old calcified lymph node or something worrisome.Urgent care is not the venue to pursue a head scratcher.

Will inflammed lung be okay after one yr after pneumonia?

Will inflammed lung be okay after one yr after pneumonia?

Pneumonia: This can be due to bronchiectasis, chronic abscess, and a variety of other factors depending upon the cause of the pneumonia, whether it was infective vs. Autoimmune vs drug-induced, etc. Need more info to answer this question effectively. Please rephrase and ask again. Good luck.

Chest and back pains. Possibly my lungs. COULD it be pneumonia? CGD? OR fibrosis?

Chest and back pains. Possibly my lungs. COULD it be pneumonia? CGD? OR fibrosis?

Not likely: Most common causes of chest and back pains are musculoskeletal in origin. More severe conditions like pneumonia, CGD, and fibrosis would likely present with additional signs/symptoms. Focus on common causes first before worrying about rare conditions. See your PCP to discuss your concerns and get a more detailed physical exam.

My 3 week old neice has pneumonia, could it be related to her underdeveloped lungs?

My 3 week old neice has pneumonia, could it be related to her underdeveloped lungs?

Possibly: It depends on the cause (type of germ) of the pneumonia and the health of the baby. A child who was premature may have more problems fighting certain virus infections or may have lung damage continuing from the nursery. A newborn who is healthy may inhale milk as a common cause of pneumonia or may get pneumonia from a germ she got from a sibling or parent. See what the doctor thinks.

My 3 week old choked/strangled on vit D drops. If it got into her lungs, what will happen? Could it cause something like pneumonia or dry drowning?

Not really: It's unlikely that you will notice any sequelae from this little event. The reason we cough and "choke" - it's our body's way of protecting itself and trying to keep stuff out of the lungs. Even with this protection sometimes, rarely stuff will get by, but most of the time actually nothing ever occurs. The tiny amount of medicine given for infant Vit D drops is inconsequential. Relax. It's okay.

14mo boy- pneumonia in both lungs. Preparing to go home from hospital tmrow. I'm nervous about raking him home. Helpful care tips once we are home?

Most treated at home: If a kid is taking fluids well, eating some and capable of taking oral meds he can do well at home. He will need adequate rest when he tires, and simple balanced nutrition for a normal recovery. As long as he wets a diaper every 4-6 hours and appears to be regaining his pre-illness playfulness, his recovery is going well.
