Can birth control make your heart beat fast? I am 33, 5 8 tall, 220 pounds. I have been having a racing heart since december on and off. When it first started it would really pound after I ate supper or when I would lay down at night. It s calmed down some, but almost always about 1 week before my period it will do it every night for 1 week and then go away. i ve had my heart checked and had normal test results. Seen an endocrinoligist and he says I have hypo-thyroidism, which doesn t make sense to me for these symptoms and I ve bee on meds for that for 3 months and no change. could it be my birth control?
