So exhausted after a little exertion makes me not want to do anything

Do you see a pulmonologist? Did you have pulmonary function test? And do you have oxymeter and check your oxygen level? Something is definitely wrong and please call your family doctor, say everything and ask for tests and a referral to a pulmonologist- Insist do not ask although I know how hard it is tomorrow demand things. Please get help

That is good news if your gases are ok! My blood gases are quite high and I do have hypercapnia and hypoxia. Drs say if anyone were to have my levels all of a sudden they would die. But my body has acclimated over time. My kidneys compensate by producing bicarbonate. The body is amazing.

Also when I was put on Oxygen in 2025 my O2 levels were in the 60's. I should not have lived with that but my body slowly adjusted. I must have been struggling with levels in the 80's for a long time not realizing it. Then it kept going down until it became critical and I was hospitalized. For some time I thought my Oximeter was inaccurate but it was not. So get a good high quality one and trust it and use it.

I wonder why some of you use Oxygen at night but not during the day. At night I can turn mine down to almost 1. During the day it has to be 2.5 or 3. Even so cannot do much that is physically active. Sitting feels the best.

@rpec Has the doctor talked about using supplemental oxygen? It really is important to keep moving to avoid losing even more capability.

@irenea8 you are saying when you are on O2 you still can't do anything physical? If so, that's the way I was. I thought it would give me a boost to do things. All I can say is all these commercials and ads that show people on portable O2 playing golf and doing physical stuff must be fake. That's why I rarely use it. Normally my O2 is 93, 94, 95 when doing nothing.

If I were not on Oxygen I would not be able to breath. My levels went down into the 60's without it (back when I was put on Oxygen). So I can certainly do more on Oxygen than off it! I can at least function now. But I cannot do much that is physical. Without the Oxygen I would not even be able to sit. By late afternoon I can usually get on the treadmill for 20 minutes. I have it set without any incline and just walk easily. Otherwise I can walk around our small house and do little tasks and sit often inbetween.

@irenea8 Glad O2 helps you. Wish it helped me. My O2 is pretty normal for having bronchiestis. It's my lungs that are functioning at 42%. Lungs are struggling to pump the O2 through the body.

Possible Reasons for Shortness of Breath (Normal O2)

Anxiety or Panic Attack: Can cause hyperventilation, creating a feeling of breathlessness.
Heart Conditions: Heart failure, arrhythmia, or valve problems.
Lung Issues: Asthma, COPD, bronchitis, pneumonia, or pulmonary embolism.
Structural Factors: Stiff lungs, fluid buildup, or scarring (pulmonary fibrosis).
Other Factors: Anemia, extreme fatigue, obesity, or lingering effects of COVID-19 ("long-hauling").
