Most women’s periods come every 21 to 35 days. If yours doesn’t arrive around the same time every month, or you skip some months, it might mean that you have too much or too little of certain hormones (estrogen and progesterone).
If you aren’t getting enough shut-eye, or if the sleep you get isn’t good, your hormones could be at play. Progesterone, a hormone released by your ovaries, helps you catch Zzz’s. If your levels are lower than usual, that can make it hard to fall and stay asleep. Low estrogen can trigger hot flashes and night sweats, both of which can make it tough to get the rest you need.
A breakout before or during your period is normal. But acne that won’t clear up can be a symptom of hormone problems. An excess of androgens (“male” hormones that both men and women have) can cause your oil glands to overwork.
Changes in estrogen and progesterone can make your head feel “foggy” and make it harder for you to remember things. Some experts think estrogen might impact brain chemicals called neurotransmitters. Attention and memory problems are especially common during perimenopause.
Your gut is lined with tiny cells called receptors that respond to estrogen and progesterone. When these hormones are higher or lower than usual, you might notice changes in how you’re digesting food. That’s why diarrhea, stomach pain, bloating, and nausea can crop up or get worse before and during your period.
Are you tired all the time? Fatigue is one of the most common symptoms of a hormone imbalance. Excess progesterone can make you sleepy. And if your thyroid – the butterfly-shaped gland in your neck – makes too little thyroid hormone, it can sap your energy. A simple blood test called a thyroid panel can tell you if your levels are too low. If they are, you can get treated for that.
