Atorvastatin increased my sensitivity to histamines, most of which are dietary.
Symptoms of histamine intolerance include persistently itching skin, tired or sore muscles especially shoulders, occasional migraines and stabbing pains in the gut, bloated abdomen, slow-thinking, and a few other things including runny nose when eating, and hay-fever. Blue cheese, matured, preserved - pickled, salted, dried or smoked - and fermented foods, wheat and alcohol are most likely to trigger symptoms.
It can be difficult to pick this up as we can deal with a certain amount of dietary histamine - only when it reaches a threshold do the symptoms appear.
The consequence for my diabetes was that blood glucose could rise 15mmol/L overnight, or fall 6 mmol/L depending on the histamine overload.
Controlling my histamine intake stabilised my background glucose levels; stopping Atorvastatin improved my capacity to deal with dietary histamine.
