It is well known that almost all people with parathyroid disease will have obvious parathyroid symptoms, while some aren't quite so sure they have any. For this latter group (about 2-5%), it can only be known several months after the operation to remove the bad parathyroid gland. Almost all of those patients who thought they didn't have any parathyroid symptoms preoperatively will claim to sleep better at night, be less irritable, and find that they remember things much easier than they could when their calcium levels were high ( nervous system problems ). Just ask your family members if you have become more irritable or cranky over the past couple of years!
Sometimes, it’s possible to find cancer before having symptoms. The American Cancer Society and other health groups recommend cancer-related check-ups and certain tests for people even though they have no symptoms. This helps find certain cancers early, before symptoms start. For more information on early detection tests, see our document called American Cancer Society Guidelines for the Early Detection of Cancer . But keep in mind, even if you have these recommended tests, it’s still important to see a doctor if you have any symptoms.
Testosterone is a steroid hormone produced in the adrenal glands of both sexes and in the testes of males and the ovaries of females. Testosterone is largely responsible for the formation and maintenance of male sex characteristics, including both the larger bone and muscle development seen in males. The testosterone levels in humans are regulated by hormones released from the brain; in males the hypothalamus and pituitary glands in the brain increase testosterone during puberty and male characteristics develop (for example, penile enlargement, facial hair, interest in sex).
