pem

Wondering if PEM itself contributes to POTS. I remember reading Prof Neil McGregor's studies showing PEM involves a hypermetabolic state where we urinate out metabolites. Does anyone know if this contributes to orthostatic intolerance / lowered blood volume?

I was browsing research and noticed that some harmful effects of hypoxia on the brain are delayed by days or even a week. The affected person appears to recover from the immediate effects but then has a delayed and marked worsening of brain health. This is in cases of major hypoxic brain damage...

So, I'm sure many of us are familiar with the idea of establishing an activity baseline, which is where the activity that you are able to manage doesn't trigger PEM. I would argue though that the concept of a baseline is inherently dangerous for PwME as it implies a position that can then be...

I have seen some discussions here and there around the puzzling fact of muscle pain being a consequence of neural exhaustion, whatever that actually means in pathophysiology, but not within a formal thread. It's not quite clear how much distinction there is between PEM and PENE. Maybe they are...

I’ve previously considered myself to be unlikely to have POTS. I can be almost normally active on very good days (paid for later). But a recent experience of tachycardia (110-135bpm when normal resting was 58-70) for days on end, and repeated instances in the days before and after that of...

https://mro.massey.ac.nz/bitstream/handle/10179/14653/02_whole.pdf?sequence=2&isAllowed=y New Zealand study of PEM using 2xCPETs at 48 or 72 hours. ABSTRACT PURPOSE: To investigate the timeline of post-exertional malaise (PEM) using objective and subjective measures in Myalgic...

A study that is of interest because it measured activity levels with an accelerometer. https://www.ncbi.nlm.nih.gov/pubmed/22032215 Unfortunately the authors did not investigate further to find out the "direction of these relations".

Abstract Myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) is a syndrome of unknown etiology characterized by profound fatigue exacerbated by physical activity, also known as post-exertional malaise (PEM). Previously, we did not detect evidence of immune dysregulation or virus...

Do you get post-exertional malaise (PEM) from going outdoors, not related to exercise? If so, do you know what causes it in your case? I've tried to reduce all the triggers of PEM I could think of when going outside, but I still get PEM. The possible triggers and solutions I've tried...

New study on PEM by the research team of Leonard Jason. I'm sure many on this forum will have filled in the online questionnaire:

The Norwegian Institute of Public Health has today published a literature search about PEM. The Norwegian ME Association asked them to make an overview of research on PEM in ME in 2015. The literature search was done in February 2019 by Lillebeth Larun (from the contested Cochrane review on ME...

A note for those who use sleep medication to help combat ME sleep issues - this might be more difficult to answer since the body becomes somewhat dependent on medication when taken chronically. If you could try to answer based on your time with ME before you ever took sleep meds or, if that is...

This new thread has been split from this thread. A Members Only thread also has relevant content. oh hallelujah. I've been thinking for years that how can any of it be of any proper use until we are really clear on what it is we're studying, especially re PEM. I think this is the only way to...

Slightly confused, as Lenny Jason is saying that this was just published when the journal webpage says first published 2016, so I went with the journal. Paywalled at https://journals.sagepub.com/doi/full/10.1177/1359105316664139

One of the most debilitating aspects of my ME is that the disease causes me major sleep inversion. On most evenings, after significant enough exertion builds up from the previous day(s), I primarily get a very strong brain wired-but-tired feeling and my gut starts becoming irritated. I also...

At the other place I started a thread (Feeling very heavy - symptom that rarely gets mentioned) with this post: " I have come across anecdotal mention of this symptom but never seen it included in any diagnostic criteria I can remember. It is something that I regularly experience a lot...
