“In the days leading up to the start of the menstrual cycle, many women experience insomnia and bloating, which disturb sleep,” says Phillips. “Make sure you give yourself time for extra rest and exercise, which mitigates PMS symptoms.” For women going through menopause, the drops in estrogen can cause insomnia, says Phillips. In addition, she says, thyroid and adrenal glands play major roles in energy levels—thyroid disorders can slow metabolism and digestion, making you feel tired; adrenal disorders, often triggered by stress, can induce chronic fatigue and body aches. If you think you have a hormonal disorder that’s draining your energy, ask your doctor about treatment options.
That last bit of advice is key to handling exhaustion. “Fatigue is essentially a side effect of every single medical condition,” says Phillips. If you’re getting enough sleep and eating right, but still feel exhausted, see your doctor.
