Menstruation is supposed to be a period when a woman’s resistance decreases, and if she does not eat normally and on time during her period, it may cause malnutrition. Poor nutrition during menstruation, especially vitamin and iron deficiency, may cause anemia. Failure to eat properly during menstruation can also have an impact on the stomach and intestines, causing stomach ulcers or acute gastroenteritis. Failure to keep up with nutrition during menstruation can directly affect menstruation, causing menstrual disorders and irregularities, which can have a bad effect on the reproductive system. When resistance is low during menstruation, failure to eat can induce diseases that do not normally occur. It is recommended to supplement nutrition and eat on time during menstruation.
