What causes headaches nuasea fatigue in women?

Headaches, nausea, and fatigue in women can be caused by a variety of factors, including:

* Hormonal changes: Women's hormones fluctuate throughout their menstrual cycle, and these fluctuations can cause a variety of symptoms, including headaches, nausea, and fatigue. These symptoms are most common during the menstrual period (premenstrual syndrome, or PMS) and the week before (premenstrual dysphoric disorder, or PMDD).

* Pregnancy: Headaches, nausea, and fatigue are all common symptoms of pregnancy, especially in the first trimester. These symptoms are caused by the sudden increase in hormones that occurs during pregnancy.

* Menstrual disorders: Some menstrual disorders, such as endometriosis and polycystic ovary syndrome (PCOS), can cause headaches, nausea, and fatigue. These disorders can also cause other symptoms, such as heavy bleeding, pelvic pain, and infertility.

* Other medical conditions: Headaches, nausea, and fatigue can also be symptoms of other medical conditions, such as thyroid problems, anemia, and depression. If you are experiencing these symptoms, it is important to see a doctor to rule out any underlying medical conditions.
