In teenage at puberty many types of changes but why in some boys delay in physical changes?
Answers
Explanation:
Puberty can be delayed for several reasons. Most often, it's simply a pattern of growth and development in a family. A guy or girl may find that his or her parent, uncle, aunt, brothers, sisters, or cousins developed later than usual, too. This is called constitutional delay (or being a late bloomer), and it usually doesn't require any kind of treatment. These teens will eventually develop normally, just later than most of their peers.
Medical problems also can cause delays in puberty. Some people with chronic illnesses like diabetes, cystic fibrosis, kidney disease, or even asthma may go through puberty at an older age because their illnesses can make it harder for their bodies to grow and develop. Proper treatment and better control of many of these conditions can help make delayed puberty less likely to occur.
A person who's malnourished — without enough food to eat or without the proper nutrients — may also develop later than peers who eat a healthy, balanced diet. For example, teens with the eating disorder anorexia nervosa often lose so much weight that their bodies can't develop properly. Girls who are extremely active in sports may be late developers because their level of exercise keeps them so lean. Girls' bodies require a certain amount of fat before they can go through puberty or get their periods.
Delayed puberty can also happen because of problems in the pituitary or thyroid glands. These glands produce hormones important for body growth and development.
