Can anything help alleviate polysaccharide storage myopathy (PSSM) in my horse?
PSSM horses can remain asymptomatic for years (average age of first appearance of symptoms is 6 years) until there is some change in their schedule, such as being laid off due to injury or not getting regular exercise due to weather. Regular daily exercise for horses with PSSM has been shown to produce a dramatic decrease in serum CK following exercise. Adjusting to a lower-starch, higher-fat diet will further support these efforts. For some horses, improvement may be evident within a few days of the new diet and exercise program. Others will take longer to metabolically adjust and show a change for the better.
