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. ...Read more

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. ...Read more

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. ...Read more

H0w serious is pleural & parenchymal scarring in both upper lobes of my lungs. I had double pneumonia at the age of two?

It depends: On the extent. If it is a minor degree of scarring, it will probably have no impact on your lung function. If it is severe, you may have impaired pulmonary function. ...Read more

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. ...Read more

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

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. ...Read more

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? ...Read more

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. ...Read more

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. ...Read more

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. ...Read more

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. ...Read more

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. ...Read more

When a child grows resistent (esbl kleb o) regularly in their lungs/trach, would high-dose amoxicillan be effective against a pneumonia (no c&s)?

When a child grows resistent (esbl kleb o) regularly in their lungs/trach, would high-dose amoxicillan be effective against a pneumonia (no c&s)?

Likely not: But not impossible. No klebsiella is sensitive to Amoxicillin since all produce an enzyme called betalactamase. Just cause one is colonized by a resistant bug doesn't mean that the bug is in the lungs causing pneumonia isn't a much more sensitive one. ...Read more

The dr said I have a lung lesion from previous pneumonia.. Its white and perfectly round. Can this be cancerous. I'm worried but the dr didn't seem to b?

Possible: But not necessarily, we often find lesions on x rays and ct scans which are not cancerous and amenable to follow up with serial imaging; however, certain radiographic features and size may warrant further investigation with pet/ct or biopsy; I suggest you discuss the findings on your imaging with a pulmonary specialist. ...Read more

Had pneumonia 5 times in 2 yrs, even now that my lungs are clear on X-ray I still have chesty cough on and off but find it hard to cough anything up. Any exercises or anything I can do?

Had pneumonia 5 times in 2 yrs, even now that my lungs are clear on X-ray I still have chesty cough on and off but find it hard to cough anything up. Any exercises or anything I can do?

Test for asthma..: It is possible that you have asthma or some postnasal drip causing you to cough. Would recommend discussing this with your doc to evaluate for likely asthma--cough variant asthma is quite common. Exercises are good for general health, including your lungs, but asthma trouble maybe preventing you from doing them. So, call you doc. Good luck. ...Read more

Is fluid on lungs and pneumonia after gallbladder removed serious?

Is fluid on lungs and pneumonia after gallbladder removed serious?

Pneumonia: Absolutely. Not sure if you are referring to pleural effusion (liquid in the space between the tissues surrounding the lungs), or to congestion due to fluid in air spaces in the lung which could be fluid overload during surgery, congestive heart failure, other. If is hospital acquired pneumonia this can be life-threatening, particularly if due to multi-antibiotic resistant microorganisms. ...Read more
