What would happen if there is an increase or decrease in the secretions of the pituitary, thyroid and pancreas?

Increase Decrease

Pituitary Excessive growth hormone (produced by this gland) for a long period of time produces a condition known as acromegaly, in which patients have swelling of the hands and feet and altered facial features. These patients also have organ enlargement and serious functional disorders such as high blood pressure, diabetes and heart disease. Shows a poor growth in children. In adults, it causes a reduced sense of wellbeing, increased fat, increased risk of heart disease and weak heart, muscles and bones.

Thyroid The release of too much thyroxine in the bloodstream is known as thyrotoxicosis, it can be recognized by a goiter which is a swelling of the neck due to enlargement of the thyroid gland. Other symptoms of thyrotoxicosis include intolerance to heat, weight loss, increased appetite, increased bowel movements, and irregular menstrual cycle. Hypothyroidism is a condition in which the thyroid gland does not make enough thyroid hormone.

Hyperthyroidism induces a hyper-dynamic cardiovascular state which manifests by a faster heart rate, higher systolic and diastolic function i.e. higher blood pressure, atrial fibrillation, and reduced exercise performance.

Pancreas With too little insulin, the body can no longer move glucose from the blood into the cells, causing high blood glucose levels. If the glucose level is high enough, excess glucose spills into the urine. If there is a decrease in insulin, cells will take in too much glucose from the blood. This leads to abnormally low blood glucose levels (hypoglycaemia).
