Symptoms of Hormonal Imbalance

Okay, so we’ve looked at the key hormones in the menstrual cycle — estrogen, progesterone, testosterone, cortisol, and thyroid. But what are the key symptoms you might notice when these hormones are out of balance? In my experience, the biggest imbalance I see in clinical practice is between estrogen and progesterone. It’s really important to see them together because it’s the ratio between the two that matters. When they’re out of balance, that “naughty” estrogen can start doing things we don’t want it to do. The most obvious signs of hormonal imbalance tend to show up in the menstrual cycle itself. For example, missing periods, very light or very heavy bleeding, or cycles that are too short or too long can all indicate an imbalance. A heavy period can mean too much estrogen building the uterine lining, while a scanty flow can indicate low progesterone or a lack of ovulation. If cycles are irregular or the luteal phase is shorter than 10 days, that often points to low progesterone. Spotting before your period can mean progesterone isn’t strong enough to maintain the uterine lining, while cramps and pain can also indicate low progesterone — remember, progesterone relaxes smooth muscle. Clotting, irregular cycles, fertility issues, or difficulty maintaining a pregnancy can all be connected to this imbalance. Miscarriages often reflect entering pregnancy with low progesterone or high estrogen. Even morning sickness or nausea can be a sign of poor estrogen clearance. PMS symptoms are another clear sign of imbalance. One of the pioneers in this field, Dr. Katharina Dalton, was the first to show that PMS was linked to low progesterone in the second half of the cycle — not something “all in our heads,” as was once believed. So if you experience headaches, mood changes, breast tenderness, or low energy that show up cyclically in the second half of your cycle, it likely reflects this hormonal interplay. Low mood, anxiety, irritability, and insomnia can all stem from estrogen being too stimulating without enough progesterone to balance it. Cyclical headaches and migraines, acne, and joint pain are also common signs, especially around perimenopause and menopause. Estrogen dominance can contribute to inflammation, thyroid issues, autoimmune conditions, and even gallbladder problems. These issues are much more common in women, partly due to estrogen’s pro-inflammatory nature when it’s unbalanced. Other symptoms can include low or excessive libido (too low may mean low testosterone or progesterone; too high can reflect estrogen dominance), bowel changes, cysts, fibroids, water retention, or night sweats. Estrogen can make cells more “leaky,” which contributes to bloating and swelling. Histamine issues are also increasingly common, especially in perimenopause — itchy eyes, runny nose, or skin reactions. That’s because estrogen increases mast cell activation and inhibits the enzyme (DAO) that breaks down histamine. Conditions such as PCOS, endometriosis, and adenomyosis are often driven by estrogen-progesterone imbalance, as well as inflammation and stress. Varicose veins, hemorrhoids, weight gain, and hair loss can also reflect underlying hormonal issues, especially when linked with thyroid or progesterone deficiency. Even emotional patterns — like difficulty letting go, constant rumination, or low resilience to stress — can reflect low progesterone. You might notice you “lose it” easily, feel dramatic or reactive, or struggle to feel calm. These are all connected to that lack of the calming, soothing influence of progesterone. In some women, even nosebleeds or biting the inside of the cheeks have been observed when estrogen is high, since it promotes tissue growth and vascular leakiness. Now, I know that’s a long list, and you might be thinking, “Oh my gosh, I have so many of these symptoms.” Please don’t panic. Symptoms are not signs that you’re broken — they’re your body’s way of getting your attention. Your body is saying, “I don’t feel safe right now; please listen.” When we ignore those signals, the body simply gets louder. So rather than seeing symptoms as something to fear, see them as communication — your body’s way of asking for balance, support, and safety. In Module Three, we’ll look deeper into why these imbalances happen, what drives them, and most importantly, what you can do to start restoring balance.
