Anemia

Anemia is a health risk of being underweight and is characterized by a lower number than normal of red blood cells. It is usually measured by a decrease in the amount of hemoglobin which is the red pigment in red blood cells that transports oxygen. Anemia can be caused by nutritional deficits common in people who are underweight and not eating a balanced diet rich in iron. Some symptoms of anemia are fatigue, pain in the chest and shortness of breath. If you are suffering from anemia, you should focus on a weight gain diet rich in nutrients and eat a lot of leafy green vegetables like kale and spinach.
