Resistance to insulin in body cells increases.
HDL cholesterol levels decreases and LDL cholesterol and triglyceride levels increase.
Increase in blood pressure.
Decrease in bone mineral density.
Calcium density in circulatory system increases.
Functioning of kidney decreases.
Neurons are lost in brain. This leads to Parkinson’s, Senile and, Alzheimer’s dementia.

Secretion of growth hormone also decreases.
Estrogen and progesterone levels drop in women.
Thyroid level decreases.
Melatonin hormone (regulates body clock) decreases.
