When I started menopause five years ago, I began having severe heart palpitations, insomnia, memory loss, fatigue, and back pain. I had my thyroid removed in my 20’s, so I thought that might have made my menopause worse. I went to several different doctors trying to find relief. I was told to reduce stress, drink less coffee, take more calcium, get more exercise–all the standard menopause advice. I continued to get worse. I kept changing doctors trying to get another answer.. They kept running the same tests and saying the same things. FINALLY a doctor tested my calcium level and then ran more tests based on that result and discovered that I had hyperparathyroidism!!!! I can’t believe so many doctors missed that. I can’t believe no one tested my calcium levels, especially when most women are told to take 1200mg of calcium daily as they approach menopause!!! All the women on my mother’s side died before reaching 60 because of heart disease. I can’t help but think they may have all died from undiagnosed hyperparathyroidism.
