In extreme cases, patients may develop double vision, corneal ulcers, and blurred or reduced vision. If left untreated, hyperthyroidism can cause heart problems due to overstimulation of the heart, leading to atrial flutter or congestive heart failure, Family Doctor explains.Thyroid is the only endocrine gland whose product is stored in such a large quantity. The storage occurs in an unusual place- the extra cellular colloid. The hormones of the colloid have four functions.
The Pituitary Tumor Network Association offers a full guide to services, resources and professionals in pituitary specialties. "Dedicated to improving the quality of life and well-being for all patients with pituitary adenomas or afflictions m/ THYROID GLAND hyperthyroidism: Graves's disease, considered an autoimmune disease, shows elevated metabolic rate, excessive perspiration, rapid, irregular heartbeat, nervousness and.Ii) They promote growth of body tissues and development of mental faculties. iii) They stimulate tissue differentiation. Example: Metamorphosis in a frog. iv) Thyroxin also controls the working of kidneys. Its deficiency results in decreased urine output and vice versa.
It is characterised by puffy appearance due to accumulation of fat in the subcutaneous tissue because of low metabolic rate and retarded oxidation. The patient lacks alertness, intelligence and becomes lethargic.TOP OF PAGE ESTROGEN AND PROGESTERONE ENDOCRINE HISTOLOGY PAGE NORMAL HORMONE SECRETIONS HOME TESTIS You are not responsible for any effects of hypo or hyper secretion of testosterone.

Ad Choices.The disorder can be treated by an early administration of thyroid hormone. It is caused by deficiency of thyroid hormones in adults. It is more common in women than in men.
It makes hormones that regulate the body's base metabolism by controlling how much energy cells use on a regular basis. Hypersecretion of hormones from the thyroid gland, which is also known as hyperthyroidism, can affect the entire body and be caused by multiple conditions.The disease is common in hilly areas and causes enlargement of thyroid gland. Hypersecretion (Hyperthyroidism) Back to Top Grave's disease (Exophthalmic Goitre) Back to Top. It is autoimmune disorder in which the person produces antibodies that mimic that action of TSH, but not regulated by normal negative feedback controls.
Improper secretion of the above thyroid hormones causes the following disorders. Hyposecretion (Hypothyroidism) Back to Top Deficiency of the secretion of the gland at birth produces this condition in infants. A cretin has markedly reduced metabolic rate and oxidation.Low intake of iodine indicated thyroiditis, whereas high uptake of the labeled iodine suggests Graves disease or a thyroid nodule. There are several ways in which hyperthyroidism can be treated. Radioactive iodine can be given to kill off any nodules, which are producing too much thyroid hormone.

It is caused by deficiency of iodine in the diet. Iodine is needed for the synthesis of thyroid hormone.
I) They control the general metabolism of the body by regulating the rate of oxidation and production of energy. They maintain the basal metabolic rate of the body and normal body temperature.Ml If you are a diabetic, the Diabetes Net can keep you updated on treatments, services and products: m/ml. ADRENAL GLAND hypersecretion of corticosteroids: Cushing's syndrome - changes in carbohydrate and protein metabolism resulting in a puffy appearance.
Patients may also suffer from fine muscle tremors, intolerance to heat and perspiration. Other symptoms include a rapid or irregular heartbeat, brittle hair, weight loss despite normal food intake and an increase in the number of bowel movements experienced each day.Finally, hyperthyroidism can cause a condition known as thyrotoxic crisis, which leads to a sudden worsening of the symptoms of hyperthyroidism. Thyrotoxic crisis is a medical emergency and requires immediate medical care.
