Can you tell me if you have a deficiency that makes you tired (like iron but not really anemia) can it stop you from growing?

Need Details. Our bodies require energy, protein, fat, carbohydrates, vitamins, and minerals. A deficiency can have consequences that are specific for what is missing. Low iron stores without anemia probably doesn't make you tired or prevent growth. For most of us, a healthy diet provides what we need. If you have health problems, you may be at risk for certain deficiencies. Ask your doctor.
