Protein–energy undernutrition (PEU), once called protein–energy malnutrition (PEM), is a form of malnutrition that is defined as a range of conditions arising from coincident lack of dietary protein and/or energy in varying proportions. The condition has mild, moderate, and severe degrees.
Post-exertional malaise (PEM), sometimes referred to as post-exertional symptom exacerbation (PESE) [1] or post-exertional neuroimmune exhaustion (PENE), [2] is a worsening of symptoms that occurs after minimal exertion.
[33]: 49 PEM usually starts 12 to 48 hours after the activity, [34] but can also follow immediately after. PEM can last hours, days, weeks, or months. PEM can last hours, days, weeks, or months. [ 10 ] : 6 Extended periods of PEM, commonly referred to as "crashes" or "flare-ups" by people with the illness, can lead to a prolonged relapse.
Polioencephalomalacia (PEM), also referred to as cerebrocortical necrosis (CCN), is a neurological disease seen in ruminants that is caused by multiple factors, one of which is thiamine depletion in the body.
Kwashiorkor is a type of severe acute malnutrition (SAM). SAM is a category, composed of two conditions: marasmus and kwashiorkor. [9] Both kwashiorkor and marasmus fall under the umbrella of protein–energy malnutrition (PEM). [10]
The biggest differences between criteria are whether post-exertional malaise (PEM) is required, and the number of symptoms needed. [ 1 ] The pathology of ME/CFS is poorly understood, and it can be a difficult condition to diagnose because there is no standard test, many symptoms are non-specific, and because doctors and patients may be ...
Protein-Energy Malnutrition (PEM) is another form of malnutrition that affects children. PEM can appear as conditions called marasmus, kwashiorkor, and an intermediate state of marasmus-kwashiorkor. Although malnutrition can have severe and lasting health effects on women and children, they are still susceptible to other water-related dangers. [10]
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form.
