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.
Direct democracy is a system of governance that started in ancient Athens, around 508 BCE. In it, all eligible citizens vote on decisions for the government rather than relying on representatives. A representative democracy, by contrast, is one in which voters select representatives who vote on their behalf.
