Stouts & Porters. Thereâs very little distinction between a Porter and a Stout, but they do have their differences. Porter is a dark, almost black, fruity-dry, top fermenting style. An ale, porter is brewed with a combination of roasted malt to impart flavour, colour and aroma. Stout is also a black, roast brew made by top fermentation.
Infections and illnesses are amongst the most common causes of temporary muscle fatigue. This is usually through muscle inflammation. Even though recovery is usual, if inflammation is severe (such as a bad bout of influenza), the weakness can last quite a while. This can sometimes trigger chronic fatigue syndrome (CFS).
When AFib causes heart failure, fluid in the lungs can cause fatigue and shortness of breath. Oxygen-rich blood is not being delivered to the body and brain, causing physical and mental fatigue and reduced stamina. Fluid also can build up in the feet, ankles, and legs, causing heart-failure related weight gain.
