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!
Although you cannot change the genes that determine how thick your skin is or how well the collagen and fibers hold up in the dermis, you can control other causes of skin thinning. For example, you can limit your amount of sun exposure. Overexposure to the sun's harmful ultraviolet rays breaks down and damages collagen in the dermal layer. When this happens, your skin is less likely to rebound from inevitable daily stretching and twisting. Avoiding or reducing your exposure to the sun's UV rays can reduce collagen loss [source: National Institute on Aging ].
