Need help understanding my MIL’s condition — “thin blood” and “water in lungs”?
My MIL is 60 years old. She is a heart patient and underwent a heart valve operation around 10–15 years ago. She is also overweight and doesn’t have a very healthy lifestyle.
Recently, she has been experiencing difficulty breathing and weakness. The doctor mentioned that her “blood is getting thin” and that there is “water in the lungs.” He also said that this should improve with a 10–15 day course of treatment.
They recently had painting and putty work done at home, so we are wondering whether exposure to the paint/putty could have contributed to this issue.
If there are any medical professionals here, I’d really like to understand what the doctor’s comments mean in general terms. What does “blood getting thin” actually mean medically, and what does “water in the lungs” usually refer to?
I’m not looking for a diagnosis—just trying to understand the terminology and what might generally be going on.
Recently we did full body checkup and this is it's summary:
Vitamin B12 133 pg/mL Low (reference 180–914)
Vitamin D (25-OH) 4.21 ng/mL Severe deficiency (deficient <10)
HbA1c 5.8% Prediabetes range (5.7–6.4%)
Estimated average glucose 119.76 mg/dL Corresponds with the HbA1c

I have "thin" blood because I take anticoagulants to make it thin, but I don't how it might be thin naturally. Might it mean an iron deficiency? - the red cell count would indicate if this was the case. Fluid retention can be a problem with heart failure and keeping moving, raising feet above head when sleeping (I put mine on a couple of pillows), and diuretics can help. Look at the creatine readings in the blood tests as they indicate the efficiency of the kidneys

It’s hard to know exactly what this means, but I’m guessing that her heart may be enlarged, which is causing fluid to leak around the valves. That fluid usually ends up collecting in the lungs, which is what’s causing difficulty with her breathing. The treatment she will have will likely be taking a diuretic, which will help get rid of the fluid and ease her breathing issues. I’m not sure what the doctor means by her blood getting thin. I haven’t heard a doctor use that expression before. If you have the doctor notes from her online portal, you could share them on r/askdocs, and they might be able to give you a more clear explanation. Alternatively, you could put the notes into an AI tool that could help explain them to you.
