No, it's my dad (77 years old) that is having them and they are increasing in frequency. I know that hyperthyroidism can be a cause as can hypoglycemia. He could be either of those two things but not severely enough to be diagnosed. I was wondering if anyone else on here had any other ideas. Heavy metal toxicity could be an issue (tons of Amalgam fillings) or the other things you mentioned. He's not sick enough to do anything radical though but I do my best to try and coax him to a healthier lifestyle (which is not bad but lots of room for improvement). Thanks for your reply.
