Physical symptoms .- Headache, pain, or increased breast tenderness, bloating, weight gain, back pain, nausea, fatigue, diarrhea or constipation, urinary problems, dry skin, cold sores, acne, etc. .
And these are felt to a greater or lesser extent depending on the woman of your age or fitness level.
But why do we feel weak?
Physical weakness that occurs during menstruation is often caused by a drop in the amount of iron we have in the body. Because of the bleeding, women hold less iron than men. That's why nutritionists recommend eating before and during menstruation foods high in iron: beet, sesame, Spirulina algae, dulse, green vegetables and lentils are the most important.
Furthermore, note that the negative connotations that have accumulated about menstruation and certain hormonal changes may alter and affect in some way your mood, feeling weaker.
If weakness is exaggerated or is accompanied by dizziness is normal to see a doctor, you may be suffering anemia.
