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

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)

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