Why might women experience tiredness all the time more frequently than men?

Some health conditions that can make people feel tired (also known as fatigue) are more common in women than men, such as iron deficiency anemia, depression, and chronic fatigue syndrome. Feeling tired can also be caused by conditions involving the female reproductive system including menopause, premenstrual syndrome, premenstrual dysphoric disorder, pregnancy, and postpartum depression. If you are wondering why you often feel tired, you should contact a healthcare provider to receive a personalized medical evaluation and advice.
