Unlike in the glandular stomachs of carnivore and ominvores, the epithelium of the rumen is not protected by a layer of mucus. This means that ruminal epithelial cells are sensitive to chemical damage, for example in increased acidity. Low ruminal pH therefore leads to rumenitis, with erosion and ulceration of the ruminal epithelium. Bacteria can then colonise the ruminal papillae and be absorbedinto the portal circulation. This bacteraemia can seed infection to many tissues and can result in, for example, liver abscesses, pneumonia, endocarditis, pyelonephritis, or arthritis  if the liver, lunds, heart valves, kidneys or joints become infected. Any of these conditions are therefore potential complications of SARA.

Subacute ruminal acidosis has also been associated with coriosis (lamintis), hoof overgrowth and solar abscesses/ulcers, which may occure weeks to months following the inciting acidotic event. The mechanism of coriosis is currently poorly understood.
