It is normal to feel particularly tired when you have your period, and most women can feel this way. The endometrium is shed during menstruation and the body loses some blood. Especially patients with uterine fibroids or excessive menstrual flow are more likely to feel tired and strained. This time, you should pay attention to rest, ensure sufficient sleep and nutrition, avoid strenuous sports or heavy physical labor, but also eat more blood and iron-supplementing foods. For example, you can eat more celery, cherries or animal blood, which are rich in iron. You also need to eat more protein, such as eggs, milk and soy milk, which help synthesize hemoglobin and improve the feeling of general weakness and fatigue.
