To review:
The rationale behind endocrine disruptions causing more harm to the children than adults.
Introduction:
Endocrine glands secrete chemical messengers (hormones) that are the mediators for various functions in the body. The hormones secreted by these glands help in wide functions like maintaining basal metabolic rate or BMR to the maturation of T-cells. There are certain chemicals found in the environment that can cause changes in endocrine functions, known as endocrine disruptors. These chemicals are especially bad for the health of the children.
Explanation of Solution
Endocrine disruptors can be defined as exogenous agents, which interfere with the production, release, transport, metabolism, binding, action, or elimination of the natural body hormones. Thus, the function of hormones to maintain the homeostasis and regulate the development process is hindered in the presence of endocrine disruptors.
Endocrine system plays an important role not just in biochemical processes, but it triggers and supports various events like childbirth, lactation, metabolic events, maturation, and puberty. In short, all the major bodily functions and life events are controlled by the endocrine system.
The endocrine disruption interferes with these functions. Thus, the body systems cannot perform their function properly. The endocrine hormones impose the harm in two basic ways that include the decreased or increased availability of the hormones.
These disruptions can cause more serious effects in children as compared to adults as children need different hormones for various events that can affect their entire life. Some of the major ones are as follows:
Bone length depends on the hormone calcitonin. Reduced level of calcitonin can result in stunted growth of the child.
Overall growth depends on the availability of growth hormone. When the growth hormone is underproduced, it can cause pituitary dwarfism while the extra availability of growth hormone causes gigantism. Both conditions affect different organs systems and psychological health of the child.
The thymus gland is active in children. The primary function of the thymus gland is the maturation of T cells. When this hormone is affected, the immunity of the child remains low throughout the life.
Thyroid hormones perform a variety of functions in the human body. Disruption of this gland can cause cretinism leading to mental retardation, growth retardation, and decreased BMR.
Most of the endocrine disruptions that happen in the later stages of life are manageable as the body is fully developed. Replacement of the hormones is enough for adults suffering from endocrine disruptions, but it is different in children.
The disturbed endocrine functions early in the growing period affect the children for the rest of their lives. Early diagnosis may help some of the children, but most of them develop irreversible changes due to endocrine disruption.
Therefore, it can be concluded that the endocrine disruption causes more harm in the children as the complications of these disruptions to affect the growth of the children and its implications are irreversible. The children affected by endocrine disruptions have to live with the certain deformities and reduced physical and mental functions for the rest of their lives.
