In women of childbearing age, the most common cause of iron deficiency anemia is a loss of iron in the blood due to heavy menstruation or pregnancy. A poor diet or certain intestinal diseases that affect how the body absorbs iron can also cause iron deficiency anemia.
Direct democracy (also known as pure democracy) is a form of democracy in which people decide (e.g. vote on, form consensus on) policy initiatives directly. This differs from the majority of modern Western-style democracies, which are indirect democracies.
A direct democracy is a democracy in which members of the public vote on laws. They make the political decisions in the country. Compare with representative democracy, one that elects people to make and vote on the laws for them. An example of a republic with a large degree of direct democracy would be Switzerland.
