One cause of this is kidney weakness.  I would concentrate on foods / 
protocols to strengthen and support the kidneys.  Some ideas I've seen 
include acupuncture, Swedish massage, contrast hydrotherapy (hot/cold 
application), herbs such as Hawthorn, etc.  Fish is a suitable 
substitute if red meat is contra-indicated.  Magnesium supplementation 
can help regulate potassium levels.  Foods high in magnesium include 
nuts and veggies such as spinach, chard, etc.  Ayurvedic medicine has 
some rasayanas (mixes of herbs/minerals in specific proportions, for 
example) that target the organs.  Gokshura is a prime herb for that 
purpose and is usually mixed with other balancing herbs.  I would look 
for a Gokshura Rasayana.  When changing over to alternative therapy, it 
is a good idea to check with the MD a little more often to see what 
effect the therapy is having.
