Disorders of the Endocrine System


Disease Occurs due to Irregular Amounts of Hormones Being Produced

  • Hyperfunction: too much hormone being produced

  • Hypofunction: not enough hormone being produced


Gigantism

  • Hyperfunction of the pituitary so too much growth hormone is produced during childhood

  • Symptoms:

    • Excessive height


Acromegaly

  • Hyperfunction of the pituitary so too much growth hormone is produced in adulthood

  • Symptoms: Overdevelopment of bones in the face, hands, and feet; protruding chin


Dwarfism

  • Hypofunction of the pituitary so not enough growth hormone is produced in childhood

  • Symptoms: Short stature


Hyperthyroidism

  • Thyroid produces too much thyroxine

  • Symptoms:

    • Goiter: Enlargement of the thyroid gland

    • Exophthalmos: Bulging eyeballs


Hypothyroidism

  • Thyroid does not produce enough thyroxine

  • Symptoms:

    • Obesity

    • Dry, itchy skin

    • Dry, brittle hair

    • Muscle cramps


Tetany

  • Hyperfunction of the parathyroid causing it to produce too much parathyroid hormone

  • Decreased calcium levels effect the function of the nerves

  • Symptoms:

    • Convulsive twitching develops

    • Person dies due to spasms of the respiratory muscles


Cushings’ Syndrome

  • Hyperfunction of the adrenal cortex which causes and increase in adrenocorticosteroids

  • Symptoms:

    • Obesity

    • Muscle weakness

    • High blood pressure

    • Excessive hair growth

    • Buffalo hump


Addison’s Disease

  • Hypofunction of the adrenal cortex results in not enough adrendocorticosteriods produced

  • Symptoms:

    • Bronzing of the skin

    • Not enough glucose in the blood

    • Low blood pressure


Diabetes Mellitus

  • Hypofuction of the pancreas causing a decrease in insulin production

  • Too much glucose is left in the blood

  • Symptoms:

    • Increased hunger and thirst

    • Increased urination

    • Weight loss

    • Blurred vision
