OSTEOPOROSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Pregnancy and lactation is known to:
A
Decrease calcium requirements
B
Result in bone mineral loss from the skeleton
C
Decrease the rate of dietary calcium absorption
D
Affect bone mineral content later in life
Explanation: 

Detailed explanation-1: -High calcium demand during pregnancy and lactation make women more prone to bone resorption and subsequent osteoporosis. Although hormonal changes cause calcium loss and result in increased bone resorption, bone resorption may be reversed after delivery (13, 14).

Detailed explanation-2: -During pregnancy and lactation there is an increased need for calcium in the mother to meet the fetus’ calcium requirements (8). In humans, this need is met during pregnancy by increased intestinal calcium absorption and during lactation by increased calcium resorption from bone.

Detailed explanation-3: -Here’s the part that may surprise you: Bone loss can occur-and in fact usually does occur-right after pregnancy, with or without breastfeeding. That’s because this is the time when estrogen levels tend to take a nosedive, just as they will when a woman’s periods slow to a stop.

Detailed explanation-4: -Poor diet, low in vitamins and calcium. Changes in hormones (from smoking or menopause) Age. Medical conditions like rheumatoid arthritis, chronic kidney disease, overactive parathyroid gland or celiac sprue.
