hormone: thyroxin overactivity (too much hormone) - increased metabolic rate - increased food intake...

Hormone: Thyroxin

Overactivity (Too much hormone)- Increased metabolic rate- Increased food intake but loss of weight- Hyperthyroidism (Grave’s disease)- Goitre (swollen neck, maybe bulging

eyes)

Grave’s disease

Hormone: ThyroxinUnderactivity (Not enough

hormone)- Hypothyroidism (Hashimoto’s disease)- Reduced metabolic rate- Low food intake but gain of weight- Myxoedema (when onset in adults)- Cretinism- stunted mental and physical

growth (in children)- Can also cause a goitre

Puffiness (swelling) Fatigue Obesity Dry, thickened skin Mental impairment Thin, brittle hair

Protuberant abdomen

Short Stature Infertility Neurological

impairment Constant Fatigue Obesity

Hormone: Calcitonin

Overactivity- Increased Bone Ca, decreased Blood Ca- Tetany (nerve problems leading to muscle spasms

or cramps)

Underactivity- Increase Blood Ca, decreased Bone Ca- Osteoporosis (brittle bones)- Kidney stones

Hormone: Parathormone (PTH)

Underactivity- Low Blood calcium, High Bone Ca- Tetany

Overactivity- High Blood calcium, Low Bone Ca- Osteoporosis

Hormone: Insulin

Overactivity- Low blood sugar level ( ↓BSL)- Hypoglycemia

Underactivity- High blood sugar level ( ↑BSL)- Hyperglycemia - Diabetes

Hormone: Glucagon

Overactivity- High blood sugar level ( ↑BSL)- Diabetes

Underactivity- Low blood sugar level ( ↓BSL)- Hyper insulinism

Hormone: Growth Hormone

Overactive- Giantism (children - very tall)- Acromegaly (adults - bones & skin

thicken)

Underactive- Dwarfism (very short)

The man holding the baby in the photo is 8 ft, 2.5 inches tall

Dwarfism occurs when there is short supply of GH in childhood. There are two types of dwarfism – Lorrain and Frohlich’s
