First, read the English article below.

Fatigue is one of the primary signs of low iron levels. Iron is essential to your red blood cells, and your red blood cells carry oxygen throughout your body. When your red blood cells are low, your body isn't getting as much oxygen as it's accustomed to, which can make you feel very tired and weak. Generally, this symptom is more than feeling a little tired for a day or two. It's a deeper tiredness that lasts over time. Because your body isn't getting enough oxygen, you may feel dizzy or lightheaded due to lack of oxygen. This can, in extreme circumstances, lead to issues with breathing, such as feeling like you can't take a deep breath. Such symptoms are rare, and typically associated with situations where someone is actively losing blood. You may also notice headaches, which are a related symptom. With low iron levels, your heart is having to work harder to pump blood to your body because it doesn't have as many cells to carry oxygen. Therefore, your fingers and toes may feel colder than normal. With your heart not pumping as efficiently, you may end up with pale skin. You may also notice this symptom in your nail beds and your gums. Because your heart is working harder to move blood through your body, you can end up with heart problems. For instance, you may have a heart arrhythmia or murmur, which can feel like your heart is skipping a beat. Your body knows it's deficient in a needed nutrient, iron, and it may come up with odd cravings for things that aren't food. For instance, you may crave dirt, ice, or starch. The main symptoms of high iron have to do with your stomach. You may experience constipation, vomiting, nausea, or stomach pain, all of which could indicate high iron levels. Stomach issues can be a sign of many diseases, so don't automatically assume these issues are from high iron.
