When should you worry about fainting?

People who faint, or often feel like they’re going to faint, need medical attention. Fainting usually is caused by a temporary drop in blood pressure. Serious reasons for blood pressure to drop include internal bleeding, heart problems, and seizures. Less serious causes of fainting include stimulation of the vagus nerve, which can occur when straining while having a bowel movement (or, for men, passing urine), having blood drawn, getting an injection, hearing bad news, or even laughing too hard.

Iron and your health

Fatigue is usually not related to a shortage of iron. In adults, iron deficiency is most common in women of childbearing age. Anemia caused by low iron does become more common with aging, affecting 10% or more of people 65 and older. This is sometimes caused by internal bleeding related to cancer or gastrointestinal disease. Most people can meet their daily iron needs from food. Red meat, poultry, eggs, and fish supply the most iron per serving. Plant foods also supply iron, but in a form that is harder for the body to absorb. People who eat few or no animal foods need to compensate by eating a larger amount of iron-rich plant foods, such as leafy greens, legumes, whole grains, and mushrooms. Foods fortified artificially with iron also help Americans to meet their iron needs. (Locked) More »
