Expert Answer:

Both over secretion and under secretion of hormones can disrupt the normal functioning of the body.

This can be understood by the following examples:

i) Thyroid hormones are very important in maintaining the overall metabolism of the body. Hypothyroidism is a common endocrine disorder resulting from deficiency of thyroid hormone. Some of the symptoms of hypothyroidism are fatigue, loss of energy, lethargy, weight gain, decreased appetite, hair loss,  muscle and joint pain, depression, emotional lability, impaired memory, constipation, impaired fertility, blurred vision etc.

ii) Aldosterone, a hormone produced and secreted by the adrenal glands. In hyperaldosteronism, overproduction of aldosterone leads to fluid retention and increased blood pressure, weakness, and, rarely, periods of paralysis.

iii) Insulin is secreted by the endocrine region of pancreas. Insufficient secretion of insulin causes the rise of blood sugar leading to diabetes.
